Position with towel roll under shoulders or with head over side of bed to extend neck and accentuate the posterior margin of the sternocleidomastoid muscle on the side of the venipuncture b. The external jugular vein will distend if its most proximal segment is occluded or if the child cries. With continuous negative suction on the syringe, insert the needle at about a 30-degree angle to the skin. Indications: Venous or arterial blood sampling in patients with inadequate vascular access or during resuscitation 2. Contraindications: Femoral puncture is particularly hazardous in neonates and is not recommended in this age group. There is also a risk in children for trauma to the femoral head and joint capsule. Avoid femoral punctures in children who have thrombocytopenia or coagulation disorders and in those who are scheduled for cardiac catheterization 3. Complications: Infection, bleeding, hematoma of femoral triangle, thrombosis of vessel, osteomyelitis, septic arthritis of hip 4. Locate femoral pulse just distal to the inguinal crease (note that vein is medial to pulse). Indications: Arterial blood sampling or frequent blood gases and continuous blood pressure monitoring in an intensive care setting 2. Complications: Infection, bleeding, occlusion of artery by hematoma or thrombosis, ischemia if ulnar circulation is inadequate 3. It is optional to infltrate the area over the point of maximal impulse with lidocaine. Prepare the site in sterile fashion (1) Puncture: Insert butterfy needle attached to a syringe at a 30 to 60-degree angle over the point of maximal impulse. Prepare the wrist with sterile technique and infltrate over the point of maximal impulse with 1% lidocaine. Make a small skin puncture over the point of maximal impulse with a needle, then discard the needle. Infuse heparinized isotonic Chapter 3 Procedures 61 fuid (per protocol) at 1 mL/hr.

Secure patient, prepare site, and drape according to the following guidelines for sterile technique6: (1) Wash hands (2) Wear hat, mask, eye shield, sterile gloves, and sterile gown (3) Prep procedure site for 30 seconds (chlorhexidine), allow to dry for an additional 30 seconds (groin: Scrub for 2 minutes and allow to dry for 1 minute) (4) Use sterile technique to drape the site b. Slip a catheter that has been prefushed with sterile saline over the wire into the vein in a twisting motion. Hyperextend the neck to tense the sternocleidomastoid muscle and turn head away from the site of line placement. Palpate the sternal and clavicular heads of the muscle and enter at the apex of the triangle formed. An alternative landmark for puncture is halfway between the sternal notch and tip of the mastoid process. Insert the needle at a 30-degree angle to the skin and aim toward the ipsilateral nipple. Right side is preferable because of straight course to right atrium, absence of thoracic duct, and lower pleural dome on right side. The needle should enter the skin 2 to 3 cm distal to the inguinal ligament at a 30-degree angle to avoid entering the abdomen. Indications: Obtain emergency access in children during life-threatening situations. This is very useful during cardiopulmonary arrest, shock, burns, and life-threatening status epilepticus.

Anterosuperior iliac spine at an angle of 90 degrees to the long axis of the body 4. If the child is conscious, anesthetize the puncture site down to the periosteum with 1% lidocaine (optional in emergency situations) c. With a boring rotary motion, penetrate through the cortex until there is a decrease in resistance, indicating that you have reached the marrow. Marrow can be sent for determination of glucose levels, chemistries, blood type and cross match, hemoglobin, blood gas analysis, and cultures. Complications: Infection, bleeding, hemorrhage, perforation of vessel; thrombosis with distal embolization; ischemia or infarction of lower extremities, bowel, or kidney; arrhythmia if the catheter is in the heart; air embolus 3. It is contraindicated in the presence of possible necrotizing enterocolitis or intestinal hypoperfusion 4. Arterial line: Low line versus high line (1) Low line: the tip of the catheter should lie just above the aortic bifurcation between L3 and L5. This avoids renal and mesenteric arteries near L1, perhaps decreasing the incidence of thrombosis or ischemia (2) High line: the tip of the catheter should be above the diaphragm between T6 and T9. A high line may be recommended in infants weighing less than 750 g, in whom a low line could easily slip out b. Catheter length: Determine the length of catheter required using either a standardized graph or the regression formula. Add length for the height of the umbilical stump (1) Standardized graph: Determine the shoulder-umbilical length by measuring the perpendicular line dropped from the tip of the shoulder to the level of the umbilicus. Determine the length of the catheter to be inserted for either high (T6 to T9) or low (L3 to L5) position b. Identify the one large, thin-walled umbilical vein and two smaller, thick-walled arteries. Use one tip of open, curved forceps to probe and dilate one artery gently; use both points of closed forceps, and dilate artery by allowing forceps to open gently f. Grasp the catheter 1 cm from its tip with toothless forceps, and insert the catheter into the lumen of the artery. Aim the tip toward the feet, and gently advance the catheter to the desired distance. If resistance is encountered, try loosening umbilical tape, applying steady and gentle pressure, or manipulating the angle of the umbilical cord to skin. Often the catheter cannot be advanced because of creation of a false luminal tract. The catheter may be pulled back, but not advanced once the sterile feld is broken h. Observe for complications: Blanching or cyanosis of lower extremities, perforation, thrombosis, embolism, or infection.
Skin samples (2 per donor) were 2 mounted on static diffusion cells with an area of 2 cm during a period of 16 hours treatment of strep throat buy thyroxine 100mcg. Sixteen hours after application remaining 14 formulation was removed from the skin surface medications information buy generic thyroxine. Results the quantities of test substance detected are shown in the following table symptoms you need glasses buy thyroxine line. Both the amount measured in epidermis and dermis as well as the amount in the receptor fluid were taken as systemically available symptoms of pregnancy purchase 200 mcg thyroxine mastercard. The area of the application site was wiped with gauze wetted with lukewarm water and dried before application. Medical and physical examination, a standard electrocardiogram as well as laboratory tests were performed before and 24 hours after application. There were no abnormal laboratory test values that were judged to be clinically important abnormalities in this study. Blood samples for haematological and biochemical parameters were taken prior to treatment and in the control and in the highest dose group prior to termination additionally. Bacteriological investigation of 2 animals revealed an infection with Staphylococcus aureus. One female of the 13 mg/kg bw/day group and one male of the 130 mg/kg bw/day group were found dead and one male of the control group was sacrificed in extremis. Ophthalmoscopic investigation revealed changes in the eyes in one control animal, one animal of the lowest dose group, 3 animals of the 130 mg/kg bw/day group and 3 animals of the highest dose group. Plaques in aorta were reported in one control male, 3 males and 1 female in the 13 mg/kg bw/day group, one male and one female in the 130 mg/kg bw/day group and in 4 males of the 1300 mg/kg bw/day group. No conclusions on dose-dependency of statistically significant changes can be obtained therefore. Dose levels were selected following results of a 7-day preliminary tolerance study performed on the same species at 2000 mg/kg bw/day. In the main study the first six males and females of the control and high dose-level groups were kept at the end of the treatment period for a two-week treatment-free period. The test substance preparations were administered as suspensions in the vehicle, 0. White blood cell and lymphocytes counts were also determined on the first six surviving animals of control and high dose-level groups at the end of the treatment-free period. A microscopic examination was performed on designated tissues for animals of control and high dose-level group at the end of the treatment period. Results No death occurred during the study and no relevant clinical signs were observed. Overall body weight gains or final body weights were similar in control and treated groups and food consumption was unaffected by treatment. In the urine neither qualitative nor quantitative changes were observed at the end of the treatment or treatment-free period. Lower absolute and relative spleen weights were observed in females given 1000 mg/kg bw/day. No treatment related macroscopic or microscopic post-mortem findings were noted at the end of the treatment period. Twenty-four hours before the end of the experiment, four 125 5 animals in each group received 0. Experiment 2 Male and female rats were divided into eight and four groups, respectively, each consisting of eight animals, and given 0 (control) or 2. Groups were killed at weeks 1, 2, 3 and 4 for males and at weeks 2 and 4 for females. Experiment 3 Male rats were divided into six groups, each consisting of eight animals, and given 0 (control) and 2. In females, however, the effects were far less significant, only 20% 125 suppression of I uptake was noted at week 4. Both, serum T3, and T4 level decreased to minimum levels after 2 weeks of Kojic acid treatment and recovered thereafter, although remaining lower than the control levels in both sexes. Experiment 3 125 125 Organic I formation returned to normal after 6 hours, I uptake per unit thyroid weight rose to 70% of the control level within 24 hours. After the end of treatment period blood samples were taken from 5 animals for hormone analysis and animals were autopsied. The remaining animals were sacrificed for measurement of 125 I uptake and its organification in the thyroid. In addition, thyroid capsular fibrosis was evident in all rats of the 2% Kojic acid group. Rat, oral, gavage Guideline: / Species/strain: F344 rats Group size: 10 males/group Test substance: Kojic Acid in 0. Blood samples for hormone analysis were collected 24 hours after final administration. Blood samples were collected 10, 30 minutes and 1, 3, 6, and 24 hours after administration. Results At 1000 mg/kg bw/day rats showed a decrease in motility, inhibition of body weight gain, and a decrease in food consumption. Groups were excluded from further examination when deaths exceeded the number of animals to be sacrificed. In the 2000 mg/kg bw/day group 11 animals died during the treatment period and in the 1000 mg/kg bw/day group one animals died in week three. Observations reported were strong sedation and tonic or clonic spasms in the groups treated with 500 mg/kg bw/day and above and bleeding from eyes, ablepsy, exophthalmos, hematuria, epistaxis and vomiting in the groups treated with 1000 mg/kg bw/day and above. Significant decreases of body weight gain occurred in the groups, which received 500 mg/kg bw/day and above, which persisted during the recovery period. No statistically significant differences in haematological parameters were reported. Urinalysis revealed protein and occult blood in urine in some of the treated animals but no dose-dependency was observed. Changes in relative organ weights occurred in lungs, liver, kidney and testes (500 mg/kg bw/day and above), spleen (1000 mg/kg bw/day) and adrenal gland (2000 mg/kg bw/day). In the 250 mg/kg bw/day group one animal showed congestion, perivascular cell infiltration and granulation in the kidney. These dose levels were selected on the basis of a previous 21-day oral toxicity study in rats and known data of a 13-week study. Treated animals were observed for abnormalities in health conditions and behaviour daily. Two days before necropsy performed 26 weeks after the initial administration and two days before necropsy performed after the end of the recovery period, urine, accumulated for 16 hours was examined. Animals were killed and subjected to macroscopic examination, selected organs were weighed, and organs/tissues were preserved. Two animals in the highest dose groups died because of injuries resulted from treatment. In the groups receiving 250 mg/kg bw/day and more, excitation and subsequent sedation were observed for two and three hours after administration of Kojic acid. In the groups receiving 500 mg/kg and more, there were also some cases accompanied by exophthalmos and salivation. Suppression of body weight gain was reported in groups receiving 250 mg/kg bw/day Kojic acid and above. Decrease of the urine volume was observed in the two highest dose groups and at 1000 mg/kg bw/day a decrease of urinary pH was reported. Decrease in absolute organ weights were reported for the heart in the dose groups treated with 500 mg/kg bw/day and above and for the spleen in the 500 mg/kg bw/day group only. Absolute organ weight increased in the adrenals in the dose groups treated with 500 mg/kg bw/day and above. In two cases of the 1000 mg/kg bw/day dose group vacuolation of anterior cells of the pituary gland was observed to a slightly greater degree compared to the control group. Test concentrations were based on the results in a toxicity test with all strains. Results the test substance was not toxic in all strains tested with and without metabolic activation.
