When released into water or air, mercury enters the environment, thereby contaminating lakes, rivers and streams. To minimize the risk of mercury pollution, mercury products, such as thermometers and blood pressure equipment, should be replaced with those that do not contain mercury. In case of a spill from a broken thermometer: x put examination gloves on both hands, x collect all droplets of mercury with a spoon, and x place in a small, closed container for disposal or reuse. Nonrecyclable x Any residual pressure should be released before aerosol containers are Aerosol Containers buried. Regardless of the type of operative procedure, the steps in processing surgical instruments and other items are the same, and are illustrated in Figure 9-1. After completing an operation or invasive medical procedure, and while still wearing gloves, the physician or assistant should dispose of contaminated objects (gauze or cotton and other waste items) in a plastic bag or leakproof, covered container. Finally, all instruments and reusable items such as surgical gloves, syringes and suction cannulae, whether or not they were used in the operation, should be decontaminated by soaking for 10 minutes in a disinfectant. This step is especially important if these items are to be cleaned by hand (Nystrom 1981). Following decontamination, the instruments and reusable items should be thoroughly cleaned with soap and water, completely rinsed and dried. Then, surgical instruments and those items that come in contact with the blood stream or touch normally sterile tissue beneath the skin (critical items) should be sterilized to destroy all microorganisms including bacterial endospores. Processing Instruments, Surgical Gloves and Other Items disinfectant do not destroy endospores reliably. Process that physically removes all visible dust, soil, blood or other body fluids from inanimate objects as well as removing sufficient numbers of microorganisms to reduce risks for those who touch the skin or handle the object. It consists of thoroughly washing with soap or 2 detergent and water, rinsing with clean water and drying. Process that makes inanimate objects safer to be handled by staff before cleaning. Process that eliminates all microorganisms except some bacterial endospores from inanimate objects by boiling, steaming or the use of chemical disinfectants. Specific guidelines for processing instruments, surgical gloves, equipment and other items used to provide healthcare services are summarized in Table 9-1. The next two columns describe how to decontaminate and clean each item, while in the last two columns the conditions for sterilizing or high-level disinfecting the item, if necessary, are presented. Additional information and evidence supporting the use of each of these processes is provided in Chapters 10–12 and Appendices E–H. When performed correctly, these processes provide excellent barriers to preventing the spread of infection from medical instruments, surgical gloves and other items to patients and healthcare personnel.

Processing instruments, gloves and other items, in Infection Prevention Guidelines for Family Planning Service Programs. The greatest risk is for staff who: x perform or assist with surgical procedures (physicians, nurses and midwives); x process surgical instruments and equipment (staff); and x perform housekeeping and waste management tasks, including disposal of infectious waste items. Decontamination and cleaning are two highly effective infection prevention measures that can minimize the risk of transmission of these viruses to healthcare workers, especially cleaning and housekeeping staff, when they handle soiled medical instruments, surgical gloves or other items. These measures are also important steps in breaking the infection transmission cycle for patients (see Chapter 1). Both processes are easy to do and are inexpensive ways of ensuring that patients and staff are at a lower risk of becoming infected from contaminated instruments and other inanimate objects. For example, in the study by Nystrom (1981), 75% of previously soiled instruments had fewer than 10 microorganisms and 98% had fewer than 100 after being decontaminated prior to cleaning. Because of these findings, it was strongly 1 Adapted from: Tietjen, Cronin and McIntosh 1992. Infection Prevention Guidelines 10 1 Decontamination and Cleaning recommended that if instruments and other items are to be cleaned by hand, they first should be decontaminated to minimize the risk of infection following accidental injury to cleaning staff as well as to reduce microbial contamination of their hands. As presented in Figure 9-1, decontamination is the first step in processing soiled surgical instruments, surgical gloves and other items. It is important, before cleaning, to decontaminate these items by placing them in a 0.

After decontamination, instruments should be rinsed immediately with cool water to remove visible organic material before being thoroughly cleaned. For example, some healthcare facilities now keep two buckets in the procedure areas or operating rooms, one filled with 0. Although this will help to 10 4 Infection Prevention Guidelines Decontamination and Cleaning prevent corrosion, even leaving the instruments in plain water for more than 1 hour can lead to rusting. Hypodermic needles and syringes that are to be disposed of should be decontaminated, placed in a puncture-resistant sharps container and, when the container is three-quarters full, burned, encapsulated or buried. If syringes (and needles) are to be reused, however, they should be thoroughly washed and rinsed after decontamination. Because it is the contaminated needle that primarily is responsible for injuries, it is recommended that only the syringe, but not the needle, be processed for reuse. Furthermore, as discussed in Chapter 14, it reduces costs and creates less contaminated waste than disposing of both. Remember: the objective Large surfaces, such as pelvic examination or operating tables, that may of decontamination is to have come in contact with blood and body fluids should be decontaminated. Once instruments and other items have been decontaminated, they can safely be further processed. This consists of cleaning and finally either sterilization or high-level disinfection.

It is either exogenous, in which infection is introduced from the outside in, or endogenous, in which the eye is seeded from the bloodstream. No fever or leukocytosis is present in exogenous cases and may also be absent in endogenous cases on presentation. Gram-positive cocci cause 95% of cases, with coagulase-negative staphylococci the major pathogens (70% of all cases). Rare, this category presents as low-grade infammation in aqueous postoperatively that persists for months. It may respond to topical corticosteroids initially but recurs as the drug dosage is tapered. Major pathogens are coagulase-negative staphylococci and streptococci (25% of cases), the latter usually causing severe endophthalmitis. A fltering bleb is a “bleb” of conjunctiva overlying a surgically created defect in the sclera. Endophthalmitis typically occurs suddenly, months to years postoperatively; incidence is 1. Infection is ofen fulminant because streptococci, including Streptococcus pneumoniae, and Haemophilus infuenzae are major pathogens. Incidence is 3% to 10% afer penetrating eye trauma (“open globe”) but may be much lower afer protocol that includes 48 hours of prophylactic antibiot ics. Sources include endocarditis (Staphylococcus aureus and streptococci are major pathogens), intraabdominal abscess (liver abscess due to Klebsiella pneumoniae in East Asian nations), transient bacteremia. This category is usually endogenous, and chorioretinitis, the earli est manifestation, is ofen asymptomatic. Chorioretinitis usually responds to systemic anti fungal treatment alone, but cases with endophthalmitis (marked vitreous infammation) also require intravitreal antifungal injection and ofen vitrectomy. Usually exogenous, this infection occurs afer eye surgery, eye trauma, or as an extension of keratomycosis (fungal corneal infection). Endogenous cases with positive blood cultures are usually presumed to be due to the same organism. Systemic antibiotics alone are not used to treat endophthalmitis, except in cases of Candida chorioretinitis. Ocular syphilis is presumed in cases of uveitis with positive specifc treponemal serology. Ocular toxoplasmosis is discussed in Chapter 280 of Mandell, Douglas, and Bennett’s Principles and Practice of Infectious Diseases, 8th Edition. Orbital infections usually have one or more of the following fndings: proptosis (which may not be grossly apparent but can be measured as 2 mm or more diference in Hertel’s exophthalmometer measurements), ophthalmoplegia, and vision loss. Subperiosteal abscesses usually require surgical drainage, and orbital abscesses almost always do.

Empirical treatment with pyrimethamine and sulfadiazine is useful when clinical and radiologic fndings are consistent with the diagnosis. Symmetrical paresthesia, numbness, and painful dysesthesia of the lower extremities can occur. Additional challenges may be posed by interrupted health insurance, homelessness, and stigma among young men who have sex with men. Disclosure is best accomplished by early adolescence to more fully engage youth in their own care, preferably before the age of sexual debut. Some are transmitted person to person, whereas others are present in certain environmental niches. Prognosis depends on the severity of the acute illness as well as prognosis for comorbidities and availability of efective and well-tolerated therapies. For some infections such as Pneumocystis pneumonia, Toxoplasma encephalitis, and disseminated Mycobacterium avium complex, primary prevention is efective, safe, and well tolerated and should be part of standard patient management.

Clinical manifestations depend on the anatomic site, age, and immune status of the host and antigenic type (1 or 2) of the virus. Recurrent lesions on the vermilion border of the lip (herpes labialis) are the most frequent manifestation of latent infection. Complications include aseptic meningitis, trans verse myelitis, and sacral radiculopathy. Magnetic resonance imaging is the neuroimaging technique of choice to identify abnormalities.

When used as a screening tool in asymptomatic patients, the sensitivity and specificity are 62% and 97%, respectively. Duplex ultrasound imaging is highly operator dependent, and these values vary widely among institutions. It is less sensitive for detecting calf vein thrombi than those located more proximally. The procedure is not an ideal screening test because of cost and potential morbidity related to the test. The detection of pelvic thrombi is poor, unless direct femoral vein puncture is performed. It may be falsely positive in the thigh after total hip arthroplasty in which there is fibrin present at the surgical site. It has a sensitivity of 100%, specificity of 49%, positive predictive value of 22%, and negative predictive value of 100%. Fondaparinux or enoxaparin for the initial treatment of symptomatic deep venous thrombosis: A randomized trial. At what depth have tissue temperature changes been recorded after treatment with superficial ice Ice application is reported to lower tissue temperature in the skin, subcutaneous tissue, and muscle, depending on the amount of subcutaneous tissue (adipose), type of cold application, and length of time treated. Patients with little subcutaneous tissue showed more significant cooling with a much shorter treatment time. Which method is more effective in lowering tissue temperature: ice massage or ice pack A 5-minute ice massage treatment in the lower extremity decreased skin temperature by 20 °C, subcutaneous tissue by 15 °C, and muscle temperature at a depth of 2 cm by 5 °C and at a depth of 4 cm by 4 °C. The extent of the temperature change seems to relate more to the length of application and the amount of subcutaneous adipose tissue. Clinical considerations include the size and location of the affected area, time allotted for ice application, and patient preference. Ice massage may produce its maximum effect sooner than an ice pack; however, if a large area is to be treated, an ice pack may be more efficient. Lower tissue temperatures produce a decrease in metabolic rate and subsequently a decrease in demand for oxygen. This decreased need for oxygen serves to limit further injury, particularly in the case of acute tissue damage, when the blood supply and oxygen delivery are impaired, resulting in hypoxia. Cold-induced lower tissue temperature raises the threshold of activation of the muscle spindle, rendering it less excitable. How may the physiologic effect of cold application be successful in reducing a muscle spasm or cramp A decrease in muscle tension is produced by the less excitable muscle spindle that is not altered by active or passive stretching exercises, which means that an ice pack can be employed successfully during a passive or active stretch of a muscle that is in spasm. The superficial vasculature has a sympathetic innervation that produces vasoconstriction when stimulated. Norepinephrine secretion and epinephrine secretion are stimulated by exposure to ice and are secreted into the blood vessels, resulting in vasoconstriction. If the tissue temperature drops below 15 °C, vasodilation occurs as a result of paralysis of the musculature, which provides vasoconstriction or a conduction block of the sympathetic nervous system. Vasoconstriction can lead to vasodilation if ice application is such that a tissue temperature <15 °C is reached. If vasodilation results, there is no definite consensus regarding the overall effect on the blood flow. Neither of these temperature ranges should bring the muscle tissue temperature to <15 °C and should not produce vasodilation within the deeper or target tissues. Frostbite occurs when the extremities or face has been exposed to cold such that there is a drop in shell temperature, resulting in freezing of the tissue. Tissue freezing occurs as ice crystals form in the extracellular areas, causing fluid to be drawn out of cells. The earliest or precursor stage of frostbite begins with tissue temperatures of 37 °Fto50°F (3 °Cto10°C). Cold-induced vasodilation occurs at temperatures <15 °C, reaching a maximum at tissue temperatures of 0 °C (32 °F). What is the ideal tissue temperature to achieve the optimal physiologic effects of cryotherapy Optimal physiologic effects from cryotherapy are achieved at tissue temperatures of 15 °Cto25°C. How long do tissue blood flow and tissue temperature remain decreased after application of an ice pack Forearm blood flow has been shown to return to normal gradually over a 35-minute period after a 20-minute ice pack treatment. A 15-minute ice pack treatment has been shown to produce a maximum intramuscular cooling effect at 28. Which form of cold treatment is the most effective at relieving postoperative pain and swelling Previous researchers reported a greater decrease in pain in those treated with a Cryocuff than in those treated with an ice pack. It is possible that, because of the postoperative dressing, the tissue temperature is not decreased to an effective level to produce analgesia or to decrease swelling in some cases. Patients receiving continuous flow cold therapy demonstrated a statistically significant decrease in pain, a decrease in pain medication usage, and an increase in range of motion 1 week after surgery compared with the patients receiving crushed ice. There did not appear to be a correlation between the severity of the disease process and the length of recovery time required. Underlying pathology to explain the slow recovery is probably related to sympathetic nervous system involvement and associated peripheral vascular disease. This needs to be considered in addition to the possibility of peripheral polyneuropathy resulting in impaired touch and hot/cold temperature sensation. Ice may be used for pain relief or decreases in muscle guarding or spasm, which may allow the therapist to achieve other objectives such as joint mobilization, stretching, or strengthening exercises. The hunting response is proposed to occur as a mechanism by which the body responds to extreme cold by vasodilation that occurs secondary to the extreme cold temperature. This vasodilation is proposed to last for 4 to 6 minutes and to be followed by vasoconstriction lasting 15 to 30 minutes. Cold-induced vasodilation has been shown to occur at tissue temperatures <15 °C, and some researchers recommend treatment duration of no greater than 20 minutes to avoid the peripheral vasodilation effect. The maximum temperature effect may not be achieved because recent studies indicate that ice pack treatment may not reach its maximum effect until nearly 39 minutes. It is designed to decrease skin temperature rapidly and to a greater extent than more traditional cold modalities. Skin temperature is rapidly decreased with gaseous cryotherapy triggering systemic cutaneous vasoconstriction. The proposed physiologic effects are pain inhibition through reduction in sodium pump activity, activation of the vasomotor reflex, and reduction in muscle tone. In a study of normal male volunteers hyperbaric gaseous cryotherapy applied to the hand produced a significant decrease in skin temperature in the dorsal hand from 32. An ice pack applied to the same area also produced a significantly reduced skin temperature from 32. At what depth have tissue temperature changes been recorded after treatment with superficial heat This may reach all desired tissues in the hand; however, in other areas of the body, subcutaneous tissue may prevent adequate heating of the desired structures. Therapeutic heating effects are achieved when a tissue temperature of 41 °Cto45°C is reached. Much greater temperatures than can be achieved with superficial heat (60 °Cto65°C) have been proposed to provide a breakdown and structural change in the collagen fiber, resulting in tissue shrinkage.
