Study drug discontinuation was highest in the first year of treatment with few subjects discontinuing after completing the first year of treatment spasms before falling asleep generic urispas 200 mg otc. Dropout rate in the first year dropped from 33% to spasms right upper quadrant cheap urispas on line 19% in phase 3 studies after implementation of required premedications and other safety mitigations spasms post stroke urispas 200mg with visa. Other common adverse reactions include injection site reactions (93%) spasms baby order 200 mg urispas visa, headache (51%), nausea (32%), abdominal pain (30%), vomiting (28%), cough (26%), hypophenylalaninemia (17%), myalgia (15%), lymphadenopathy (14%), and erythema (13%). The subject was a firefighter who was fatally electrocuted while on his ladder truck carrying a water hose. The investigator reported this event as not related to pegvaliase-pqpz treatment and the review team agrees with the Applicant’s assessment. In clinical trials of pegvaliase-pqpz with induction/titration/maintenance dosing, 26 out of 285 (9%) patients experienced a total of 37 anaphylaxis episodes. Signs and symptoms of anaphylaxis reported in clinical trials included syncope, hypotension, hypoxia, dyspnea, wheezing, chest discomfort/chest tightness, tachycardia, angioedema, throat tightness, skin flushing, rash, urticaria, pruritus, and persistent gastrointestinal symptoms. In clinical trials, anaphylaxis generally occurred with 1 hour after injection (84%, 28/37 episodes), however delayed episodes also occurred up to 48 hours after administration. All occurrences of anaphylaxis were managed successfully with the safe use conditions implemented in the clinical studies and all events resolved without sequelae. Management of anaphylaxis in clinical trials included auto- injectable epinephrine (54%, 20/37 episodes), corticosteroids (54%, 20/37 episodes), antihistamines (51%, 19/37 episodes), and/or oxygen (5%, 2/37 episodes). Eighteen out of the 26 (69%) patients who experienced anaphylaxis were re-challenged and 5 (28%) had recurrence of anaphylaxis. Anaphylaxis requires immediate treatment with auto-injectable epinephrine should be prescribed to patients receiving pegvaliase-pqpz. Prescribers should instruct patients to keep auto-injectable epinephrine readily available at all times during pegvaliase-pqpz treatment, how to properly self-inject epinephrine if needed, and to seek immediate medical care upon its use. Prescribers should also consider the risks associated with auto-injectable epinephrine use when prescribing pegvaliase-pqpz. The risks and benefits of pegvaliase-pqpz should be considered when readministering pegvaliase-pqpz following an episode of anaphylaxis. Prescribers can consider premedications with a H1-receptor antagonist, H2-receptor antagonist and/or antipyretic prior to each dose of pegvaliase-pqpz based upon clinical judgement. Prescribers may consider having an adult observer for patients who may need assistance in recognizing and managing anaphylaxis during pegvaliase-pqpz treatment. If an adult observer is needed, the observer should be present during and for at least 60 minutes after pegvaliase-pqpz administration, should be able to administer auto-injectable epinephrine, and to call for emergency medical support. In animal reproduction studies, subcutaneous administration of pegvaliase-pqpz to pregnant rats during organogenesis resulted in adverse developmental outcomes at the 1. In pregnant rabbits, subcutaneous administration of pegvaliase-pqpz during organogenesis resulted in a high incidence of malformations throughout the skeletal system, and in the kidneys, lungs, and eyes. Embryo-fetal toxicity (increased resorptions and reduced fetal weight) was also observed. The Applicant has proposed a pregnancy pharmacovigilance program to monitor outcomes in patients exposed to pegvaliase-pqpz during pregnancy. The labeling will state that pegvaliase-pqpz should be initially administered under the supervision of a healthcare provider equipped to manage anaphylaxis and the patient should be closely observed for 60 minutes following injection. This instruction is so that prior to self-injection, healthcare providers may confirm patient competency with self-administration, the patient’s ability to recognize signs and symptoms of anaphylaxis and ability to administer auto-injectable epinephrine. After confirmation of self-injection technique and counseling and training on how to recognize and respond to signs and symptoms of anaphylaxis, pegvaliase-pqpz will be administered by the patient or the patient’s caregiver at the patient’s home. The patient is required to have auto-injectable epinephrine readily available at all times during pegvaliase-pqpz treatment. The review team agrees that these additional measures may be useful for some patients and can be implemented at the prescriber’s discretion using clinical judgement, but should not be required for all patients. These strategies included mandatory premedication, mandatory access to auto-injectable epinephrine, a (b) (4) responsible adult to observe the patient for one hour post injection and education to recognize the signs and symptoms of anaphylaxis. The proposed safe use conditions include patient enrollment and counseling and auto-injectable epinephrine. Prescriber certification will ensure that prescribers are informed about the risk and the need to counsel and enroll patients, as well as prescribe each patient auto-injectable epinephrine. Pharmacy certification will ensure that patients and prescribers are enrolled prior to dispensing. Additionally, the pharmacy will verify that patients have access to auto-injectable epinephrine. The safe use conditions will ensure that patients are counseled about the risk and will have auto-injectable epinephrine available during treatment with (b) (4) pegvaliase-pqpz. We do not agree with the other proposed safe use conditions, (b) (4), as they will not ensure that the benefits of pegvaliase-pqpz outweigh the risks (See further comment in Section 8). The impact of these interventions on the anaphylaxis rate was uncertain (b) (4) in the clinical trials and the inclusion pose additional undue burden. Reviewer Comments: the proposed timetable for submission of assessments is acceptable. The Agency informed the Applicant of these requirements, and they were included in the May 22, 2018 submission. All other initially submitted materials were agreed to be necessary by the Agency. Number of completed post-training knowledge assessments for healthcare providers including methods of completion and number of attempts to complete b. The number of patients/healthcare providers/pharmacies/distributors that were de-enrolled and the reason for de-enrollment 4. Number of contacts by stakeholder type (patient/, healthcare provider, pharmacy, distributor, other) ii. Include a line listing of all cases that includes: manufacturer control number, narrative, and assessment of causality b. Audits: Summary of audit activities conducted during the reporting period including but not limited to a. Number of prescribers and pharmacies and distributors de-certified and reasons for decertification and actions to address non-compliance 3. Number of shipments sent to non-certified pharmacies, sources of the reports, and actions taken to prevent future occurrences 9. The need to counsel patients about the risk of anaphylaxis and how to recognize and respond to signs and symptoms of anaphylaxis iii. In those patients who reach a target maintenance dose and meet eligibility criteria, the 20 mg and 40 mg treatment arms maintained Phe reduction while the placebo arms had Phe elevation to pretreatment levels. If patients respond to pegvaliase-pqpz treatment, they may be able to liberalize their restricted diet. This would have psychosocial implications such as not having to calculate protein/Phe intake, eating meals with others, and a more palatable diet. Auto-injectable epinephrine must be prescribed to all patients receiving pegvaliase-pqpz and should be readily available at all times during pegvaliase-pqpz treatment. Appended materials will include: a prescriber enrollment form, prescriber guide, prescriber knowledge assessment, a program overview, pharmacy enrollment form, patient enrollment form, patient guide, safety video, wallet card, and a website. The prescriber knowledge assessment will ensure that prescribers understand the key messages included in the prescriber training at the time they take the assessment. Patient directed materials include a wallet card, a safety video, and a patient guide to present information about the risk and what to do in the event they experience anaphylaxis, and that they must have auto-injectable epinephrine available at all times during treatment. Due to uncertainty of its effect on the anaphylaxis rate in clinical trials and the questionable real-world (b) (4) feasibility, the (b) (4) (b) (4) Agency concluded that the use of monitoring by a trained observer (b) (4) (b) (4) will not mitigate the risk of anaphylaxis for patients using pegvaliase-pqpz. The Agency’s current thinking is that the need for an observer should be determined by the healthcare provider based on individual patients’ needs. Although the use of premedications may provide symptomatic relief of hypersensitivity-associated clinical findings such as rash, itching, and fever, the benefits do not outweigh the risks of required premedications for all patients using pegvaliase-pqpz and anaphylaxis events continued to occur despite patients using premedications. Additionally, the use of multiple medications may mask the early signs of hypersensitivity or anaphylaxis as well as may result in pill burden for patients. The Agency concludes that it should be per the prescriber’s digression whether their patient could benefit from the use of premedications and specifically which premedications to use. Prescribers must understand this risk, the importance of patient counseling and ensure that the patient has access to auto-injectable epinephrine. Additionally, pharmacy certification will help to ensure that the safe use conditions are met by verifying that patients have been enrolled into the program by their prescriber and confirming that the patient has auto- injectable epinephrine before dispensing pegvaliase-pqpz.

Set up Following a general introduction about adverse effects of transfusion of blood components and the differential diagnosis and treatment of acute transfusion reactions (7. Chapter 9 discusses the requirements that a hospital must meet concerning the monitoring of the transfusion chain, such as having access to a functioning blood transfusion committee, a haemovigilance official, a haemovigilance employee, and a training and further education program for all those involved in the transfusion chain. For this guideline, it was decided to divide according to cause, namely into non-infectious and infectious complications. In addition, the categorisation into acute symptoms during or within 24 hours of the transfusion and non-acute symptoms more than 24 hours after the transfusion is also used. All acute reactions – except those due to bacterial contamination – are non-infectious. Acute reactions require an acute diagnostic and – if necessary – treatment policy. For this reason, we will first focus on the diagnosis and treatment of acute transfusion reactions. Fever: fi 2 °C temperature increase and/or cold shivers: consider bacterial contamination, take blood cultures (aerobic/anaerobic) from patient and Blood Transfusion Guideline, 2011 279 279 component; in the case of sepsis, treat as such and start antibiotics; consider haemolytic transfusion reaction (see paragraph 7. Itching/urticaria: If there are no anaphylactic symptoms (such as glottis oedema, hypotension, shock): consider administering an anti-histamine. The recommendations provided below are based on the opinions of experts and international guidelines (evidence level 4). A nurse must observe the patient for 5 to 10 minutes after starting the transfusion of each new unit. Clearly define which parameters should be monitored (heart rate, temperature, blood pressure, etc. In the case of a (suspected) transfusion reaction other than itching or urticaria, the transfusion should be stopped and the unit disconnected if necessary, in consultation with the treating physician. Rapid and targeted examination by the blood transfusion laboratory is also required. The treating physician should be contacted for the differential diagnosis and treatment of acute transfusion reactions. It is recommended that the treating physician follows the above-mentioned algorithm (7. For more detailed recommendations for (suspected) specific reactions: see paragraph 7. If anaphylactic symptoms (such as glottis oedema, hypotension, shock) are present: disconnect the unit immediately, connect a neutral infusion solution. Before disconnecting the unit, it should first be sealed (‘clamped’), in order to prevent the reflux of blood from the patient to the donor unit. If the blood component is disconnected, it should be returned to the blood transfusion laboratory as soon as possible for further examination. The hospital must provide instructions for disconnection, transport & storage conditions, and the method of sampling and these instructions must be followed. Reporting: Transfusion reactions must first be reported to the treating doctor and the blood transfusion laboratory. The blood sample for compatibility testing (also called cross-match blood) must be stored for seven days at a maximum of 4 °C to 8 °C for testing of possible transfusion reactions. Systematic training of nurses in the field of prevention, recognition and treatment of transfusion reactions is indicated. In addition to a haemovigilance official, each hospital should also have a haemovigilance nurse/employee. An important task of the haemovigilance nurse/employee is the training of all people involved in the prescription and administration of blood components (see Chapter 9. The working group is of the opinion that haemovigilance should encompass both transfusions of (short shelf-life) blood components and blood-saving techniques. Symptoms can include: decrease in blood pressure fi 20 mmHg systolic and/or diastolic, fever/cold shivers, nausea/vomiting, back pain, dark or red urine, no or only slight increase in Hb or unexpected decrease in Hb. Incompatible units of plasma and platelet concentrates can also cause haemolysis due to antibodies and in rare cases can cause an acute haemolytic transfusion reaction. Activation of the complement system causes the release of anaphylatoxins (C5a, C4a, C3a), serotonin and histamine, which in turn cause some of the clinical symptoms associated with an acute haemolytic transfusion reaction. Various mechanisms activate the clotting cascade and this Blood Transfusion Guideline, 2011 281 281 results in disseminated intravascular coagulation. The release of haemoglobin in plasma results in haemoglobinuria; the acute renal insufficiency is caused primarily by renal ischaemia (Rudmann 1995, Mollison 1997). Fortunately, the acute haemolytic transfusion reaction is rare, but the true incidence is hard to determine due to under-reporting and the diagnosis can also be missed because the clinical symptoms are not specific. The clinical symptoms of an acute haemolytic transfusion reaction can occur even after transfusion of a minimal amount of incompatible blood; however, the most severe reactions are usually seen after transfusion of larger quantities (> 200 mL). The most common symptoms are fever and cold shivers, but sometimes a transfusion reaction starts with a feeling of general malaise and back pain. In addition, dyspnoea, a light-headed feeling, pain at the infusion site or chest pains and nausea can occur. The most severe cases are accompanied by hypotension and shock, acute renal insufficiency with anuria and a (strongly) elevated tendency to bleed due to disseminated intravascular coagulation. In unconscious patients or patients under general anaesthesia, an increased tendency to bleed can be the first (or only) symptom of an acute haemolytic transfusion reaction. Differential diagnosis should include auto-immune haemolytic anaemia, cold agglutinin syndrome and non-immunological causes such as transfusion of a strongly haemolytic erythrocyte concentrate. C Rudmann 1995, Mollison 1997 Acute haemolytic transfusion reactions are rare, but can be very severe and are usually the result of administrative errors in the transfusion procedure.
The cyst is usually situated in the right cardiophrenic angle and is oval or spherical spasms behind knee 200mg urispas. Lymph nodes – the paratracheal spasms under sternum purchase cheap urispas, tracheobronchial spasms of the esophagus cheap urispas 200mg mastercard, bronchopulmonary and/or subcarinal nodes may be enlarged muscle relaxant powder buy urispas with paypal. This may be due to neoplasm (most frequently metastatic bronchial carcinoma), reticuloses (most frequently Hodgkin’s disease), infection (most commonly tuberculosis, histoplasmosis or coccidioidomycosis) or sarcoidosis. Extramedullary haemopoiesis – with splenomegaly ± bone changes of specifc disease entities. Anterior (Morgagni) hernias are usually on the right, and posterior (Bochdalek) hernias usually on the left. Linear soft-tissue densities representing omental vessels help to distinguish hernias which only contain omental fat from pericardial fat pads. Liposarcoma – can contain calcifcation, and may also appear as a soft-tissue mass with no visible fat, due to excess soft-tissue component of the sarcoma. Mediastinal lipomatosis – associated with Cushing’s syndrome, steroid treatment and obesity. Occasional calcifcation in cyst wall, and air in cyst if communicating with airway. However, measurements are misleading, and a multilobular appearance or focal alteration in shape is abnormal at any age. Thymoma – occurs in 15% of those with myasthenia gravis (usually occurring in the fourth decade) and 40% of these will be malignant. If malignant it is usually locally invasive and can extend along pleura to involve the diaphragm and even spread into the abdomen. Lymphoma* – thymus is infltrated in 35% of Hodgkin’s disease but there is always associated lymphadenopathy. Pulmonary infarct – do not confuse with the mismatched perfusion defect of embolus. Asthma or acute bronchitis – may also show mismatched ventilation or perfusion defects. Aortic valve calcifcation – bicuspid aortic valve, degenerative aortic sclerosis, previous rheumatic fever. Atheroma – the amount correlates with the patient’s cardiovascular risk profle independent of other risk factors. Chronic renal failure – often heavy diffuse calcifcation which is partly related to advanced atheroma. Focal myocardial thickening Hypertrophic cardiomyopathy – the classical form affects the base of the interventricular septum, which can cause obstruction of the left ventricular outfow tract. Lipomatous hypertrophy of the interatrial septum – normal variant associated with obesity and steroid use. Haemopericardium – from acute aortic dissection, trauma including surgery, acute myocardial infarction, tumour (primary, local tumour invasion, metastases, lymphoma). Can occur following pericarditis, trauma including surgery, radiotherapy – underlying cause is often idiopathic. Thrombus – ventricular after acute myocardial infarction and in aneurysms, left atrial in atrial fbrillation, particularly the left atrial appendage, right atrial usually associated with indwelling venous catheters with insuffcient anticoagulation. Benign tumours – the commonest are myxomas, which occur most frequently in the atria. Malignant tumours – primary malignant tumours are rare but tend to be sarcomas, particularly angiosarcomas and rhabdomyosarcomas. Metastases are the commonest form of cardiac tumour (melanoma has a predilection). Myocardial infarction – the distribution is subendocardial or full thickness and in a recognized coronary artery territory. The distribution is not that of infarction and is often mid-myocardial or subepicardial. The fnding of myocardial scar tissue in this way tends to be associated with a worse prognosis. Diffuse late enhancement – can be seen with extensive cardiac amyloid infltration. It is currently believed that an oblique course of the proximal anomalous vessel as it passes through the wall of the aorta is the feature that makes patients with these anomalies most prone to sudden cardiac death. Inferior wall defects – may result from diaphragmatic motion or the increased distance of this wall from the camera. Classifed as type A if it involves the aorta proximal to the left subclavian artery and type B if it involves only the aorta distal to the left subclavian artery. X-ray signs – include widening of the mediastinum, ill-defned mediastinal outline, left pleural effusion or pleural cap, displaced intimal calcifcation. There may be no contrast opacifcation of the right coronary artery if it is involved with the dissection. Focal ulceration of the aortic wall – at the site of intimal atherosclerotic plaques, particularly in the descending aorta. Usually occurs at the isthmus in the proximal descending aorta – due to tethering by the ligamentum arteriosum. X-ray signs – include widening and ill-defnition of the mediastinal contour, left apical cap and left pleural effusion. The normal circular contour of the lumen of the aortic isthmus is lost and there may be a pseudoaneurysm. If segment A atrophies – produces the normal arrangement of the head and neck vessels from a left-sided aortic arch. If segment B atrophies – there is a left-sided arch with an aberrant right subclavian artery. If segment C atrophies – the aortic arch is right-sided with an aberrant left subclavian artery. This is associated with a low (~12%) incidence of congenital heart disease including Fallot’s tetralogy and coarctation. If segment D atrophies – the aortic arch is right-sided with mirror-image branching of the head and neck vessels. This is associated with a high incidence (~98%) of congenital heart disease, particularly Fallot’s tetralogy. Cystic medial necrosis – seen in Marfan’s syndrome, Ehlers– Danlos syndrome and with bicuspid aortic valves. Yes 5 Are the peripheral pulmonary arteries enlarged No Pulmonary hypertension (pulmonary plethora)fi Computed tomography and magnetic resonance imaging of pulmonary hypertension: pulmonary vessels and right ventricle. Atrial or mitral valve level obstruction – mitral stenosis, mitral valve obstruction. Pathogenesis in acute aortic syndromes: aortic dissection, intramural hematoma, and penetrating atherosclerotic aortic ulcer. The most sensitive signs are in the right upper quadrant (often oval gas over the liver or a hyperlucent liver). In infants a large volume of gas will collect centrally, producing a rounded, relative translucency over the central abdomen. Iatrogenic (surgery, peritoneal dialysis) – may take 3 weeks to reabsorb (faster in obese and children). Fluid-flled bowel – closed-loop obstruction, total active colitis, mesenteric infarction (early), bowel washout. Zenker’s diverticulum – posteriorly, usually on left side, between the fbres of the inferior constrictor and cricopharyngeus. Can cause dysphagia, regurgitation, aspiration and hoarseness ± an air–fuid level. Lateral pharyngeal pouch and diverticulum – through the unsupported thyrohyoid membrane in the anterolateral wall of the upper hypopharynx. Diverticula are uncommon and are seen in patients with chronically elevated intrapharyngeal pressure. Lateral cervical oesophageal pouch and diverticulum – through the Killian–Jamieson space. Developmental – failure to complete closure of tracheo- oesophageal communication. Signs characteristic of refux oesophagitis are: (a) A gastric fundal fold crossing the gastro-oesophageal junction and ending as a polypoid protuberance in the distal oesophagus.

Applications Cardiac surgery Re-infusion of the blood evacuated during surgery and the drain blood lost post-operatively is an efficient way of saving on donor blood (Ferrari 2007, Klein 2008). These are usually without clinical relevance (Krohn 2001, Sinardi 2005), but some authors have demonstrated an increase in post-operative blood loss (Schonbergen 1992, Wiefferink 2007). Washing of the collected blood, which significantly reduces these complications, must definitely be performed if the blood is suctioned peri-operatively (Carrier 2006, Westerberg 2005, Djaiani 2007, Svenmarker 2004). Orthopaedics Re-infusion of peri-operatively suctioned washed blood and (un)washed blood lost post- operatively was shown in most studies to be an efficient way of saving on donor blood (Huet 1999,Tylman 2001, Jones 2004, Carless 2006, Tsumara 2006, Smith 2007, Zacharopoulos 2007, Amin 2008, Tripkovic 2008; Munoz 2010, see table 8. Approximatley 75% of post-operative blood loss takes place in the first 6 hours post- operative. This corresponds to the time normally maintained for the interval in which drain blood can be re-infused. There are indications that a 6-hour period results in better wound healing than when a longer period is maintained (Wood 2008). According to some (So-Osman 2006, Kirkos 2006, Hendrych 2006), re-infusion of the unwashed blood causes a mild febrile reaction, although other authors cannot confirm this (Moonen 2008). Blood Transfusion Guideline, 2011 355 355 this concentration is elevated in collected blood in the first 6 hours and even increases 7- fold over the next 6-hour period (Handel 2006). The higher concentration of interferon gamma could point to improved immunity after re-infusion of unwashed drain blood (Gharehbaghian 2004). Vascular surgery Auto-transfusion of washed blood is used frequently during major vascular surgery. Despite this, few randomised studies have been published, including Wong 2002, Takagi 2007; (see table 8. Obstetrics Auto-transfusion of washed blood is used during ectopic pregnancies and Caesarian sections (Thomas 2005, Selo-Ojeme 2007). It has been demonstrated that these harmful substances are removed by washing (Thomas 2005). Re-infusion of erythrocytes from the child can promote antibody formation in the mother. Most Caesarian sections result in very little blood loss, so that routine use is not indicated. Urology Auto-transfusion of washed blood is often used during radical cystectomies and prostatectomies, without irradiation of the blood. Various studies have demonstrated that the survival is the same as for surgical patients who did not receive auto-transfusion (Nieder 2004, 2007, Davis 2003, Ford 2007, Gallina 2007, Stoffel 2005, Waters 2004). A recent randomised study of patients with abdominal trauma with perforation of the bowel found that – with the use of auto-transfusion – significantly fewer blood transfusions (6. Blood visibly contaminated by faecal matter was suctioned into a different container. This means that auto-transfusion can be used under these conditions in emergencies (Bowley 2006). Contra-indications Contra-indications for peri-operative auto-transfusion are: rinsing with toxic substances, locally used heamostatics, bacterial contamination (relative), tumour surgery (relative) and sickle cell anaemia. In emergency situations, antibiotics can be given in the case of bacterial contamination. In general, tumour surgery forms a contra-indication to auto-transfusion due to the risk of haematogenic metastasis of tumour cells. Centrifugation and washing does not result in removal of all tumour cells and results in less than 1 log reduction of the other cells (Hanssen 2002, 2004, 2004, 2006, Thomas 1999, Stoffel 2005). The 7 tumour load in peri-operatively suctioned blood can be up to 10 cells per liter (Hanssen, 2002, 2006). Leukocyte filtration results in 1 log reduction (Thomas 1999, Hanssen 2004, 2006), but irradiation of washed blood with 50 Gy results in at least a 10 log reduction of the number of viable tumour cells (Thomas 1999, Hansen 2002). A combination of leukocyte filtration followed by irradiation effectively disables active tumour cells (Poli 2008). Experiences of peri-operative auto-transfusion (including safety) have now been described for over 700 oncological surgery procedures (Hanssen 2004, Valbonesi 1999). Auto-transfusion can be life-saving during oncological surgery in Jehovah’s Witnesses (Nieder 2004). Ramirez 2002 Orthopaedics 8 filters Fat, leukocytes and micro- C tested for fat filtration aggregates removed by surface filters and not effective with screen filters. Only 21% In other words, 10 of the patients had circulating tumour cells in 500 tumour cells in venous sample. A1 Carless 2006 Peri-operatively, cell savers in which blood is washed, can be used safely and without limitation. Level 1 A2 Carrier 2006, Westerberg 2005, Djaiani 2007, Svenmarker 2004 Post-operatively, both a technique in which blood is washed before being returned and a technique in which it is not washed can be used safely up to 6 hours after connection of the drain (excluding 1 hour required for Level 1 infusion). A1 Moonen 2008 364 Blood Transfusion Guideline, 2011 Blood evacuated peri-operatively during cardiac surgery should be washed before re-infusion in order to prevent complications. Level 1 A2 Djaiani 2007, Westerberg 2005 A2 Carrier 2006 Auto-transfusion of washed blood can be used safety for obstetric bleeding. C Thomas 2005 Auto-transfusion of washed blood during tumour surgery is safe, provided the blood for re-infusion is irradiated at 50 Gy, with or without the use of a Level 3 leukocyte filter. C Hansen 2004, Poli 2008 Other considerations Auto-transfusion of blood lost peri-operatively is the most commonly used blood saving technique in the Netherlands. One advantage of this technique is that the blood can be collected first and one can decide at a later stage whether it should be processed and/or returned to the patient. In the Netherlands, the equipment is usually operated by anaesthesiology technicians or – in the case of post-operative use – recovery room nurses / ward nurses which does not require additional specialised personnel. The safety of re-infusion of peri-operatively collected unwashed blood has not been demonstrated or published in large series. Consider the use of peri-operative auto-transfusion techniques for expected major blood loss. Bacterial contamination poses a contra-indication for use of peri-operative auto- transfusion. This is relative in emergencies, administration of antibiotic prophylaxis is indicated. Oncological surgery is a relative contra-indication for the use of peri-operative auto- transfusion. The technique can be used, provided the blood is irradiated at 50 Gy before re-infusion, with or without a leukocyte filter. Peri-operative auto-transfusion can be life-saving during oncological surgery on Jehovah’s Witnesses. Post-operative re-infusion of unwashed drain blood in cardiac surgery and orthopaedics should be limited to 15% of the circulating blood volume in adults, with a maximum of 1,500 mL. Use of the unwashed peri-operative auto-transfusion technique is not recommended in children. The preferred combination depends on the expected quantity of blood loss, the initial Hb of the patient, the condition of the patient and the nature of the procedure. For heart operations, the combination of acute normovolemic haemodilution and peri-operative auto- transfusion and tranexamic acid is often used. For all combinations, the peri-operative transfusion trigger that is used largely determines the expected yield (Weber 2000). Level 3 C Weber 2000 Other considerations Each technique has its own contribution to prevent allogeneic blood transfusion. By using each specific effect and by careful planning, it is possible to compensate for blood loss over 5 litres without a single allogeneic blood transfusion. For an optimal yield, it is important to determine a strategy in advance, which takes into account the nature of the procedure, the Hb and the expected blood loss. The working group is of the opinion that a specific recommendation per procedure would exceed the scope of the Blood Transfusion Guideline. Where possible, use a combination of techniques to reduce the number of allogeneic blood transfusions.

These predictably poorer long term results likely skewed overall conclusions of the meta-analysis. This will impact the clinical practice of many orthopedic surgeons and will restrict access to a therapy that hundreds of thousands of patients currently benefit from or may 02. Non surgical options for patients with osteoarthritis are limited and are either plagued with compliance issues or have demonstrated potential adverse affects. As we described above, we think that the Strong recommendation is scientifically overstated. We congratulate the authors on their efforts to prepare, interpret, analyse and review the literature set forth in these guidelines. Hyalgan is a viscous solution of purified natural sodium hyaluronate extracted from rooster combs, the salt form of hyaluronic acid. Hyaluronic acid, by virtue of its viscosity, elasticity and other rheological properties acts as a lubricating and shock absorbing fluid in joints. Many trials assessed the efficacy of hyaluronic acid in relation to the knee joint. In 2011, the most recent review of the hyaluronic acids was published by Bannuru et al  with the objective to evaluate the therapeutic trajectory of these agents versus placebo. The investigators computed effect sizes for change from baseline at 4, 8, 12, 16, 20 and 24 weeks, using Bayesian random effects model. Multivariate analysis was performed adjusting for correlation between time points. This therapeutic trajectory was consistent with the subset of high-quality trials and on multivariate analysis adjusting for correlation between time points. With this additional perspective, we are able to infer that hyaluronic acid is efficacious by 4 weeks, reaches its peak effectiveness at 8 weeks and exerts a residual detectable at 24 weeks . Considering the effect sizes of Bannuru pooled analyses all the relative value were above 0. The review identified 40 trials that included comparisons of hyaluronic acid with a placebo (either saline or arthrocentesis). The conclusions of the Cochrane Collaboration Review of Viscosupplementation are diametrically opposite to your current recommendation. In addition, failure to use the studies that compare intra-articular viscosupplementation to non-steroidal anti-inflammatory drugs (all of which seem to identify equal efficacy, with potential improved safety with the intra-articular injections versus oral non-steroidals) has resulted in a strong recommendation for oral non-steroidals, at the same time a strong recommendation against viscosupplementation, while in head-to-head comparison the two are equal with improved safety with the viscosupplementation (as per John C. A 2003 meta-analysis of studies reported from 1966 to 2003 and the Cochrane Controlled Trials Register pooled the results of 22 trials of intra-articular hyaluronan versus intra-articular placebo injections. The authors concluded that hyaluronan injections were superior to the intra-articular saline injections . The magnitude of effect could be considered modest, but it exceeds a minimally clinically significant threshold. Moreover, this treatment can delay the need for surgical procedures within the 2-years follow-up period. All the patients who responded did not need any surgical intervention for at least 2 years during the follow-up period.
