These steioids aie capable of preventing or suppressing the development of the sweUing, redness, local heat, and tenderness which characterize inflammation. They inhibit not only the acute symptoms of the inflammatory process, such as edema, fibrin deposition, and capillary dilatation, but also the chronic manifestations. There is evidence that glucocorticoids induce the synthesis of a protein that inhibits phosphoHpase A 2 (60), diminishing the release of arachidonic acid from phosphoHpids (Fig. 2), thereby reducing chemotaxis and inflammation. 

Toxicity of 2-Ghloroethanol. Ethylene chlorohydrin is an irritant and is toxic to the Hver, kidneys, and central nervous system. In addition, it is rapidly absorbed through the skin (73). The vapor is not sufficiently irritating to the eyes and respiratory mucous membranes to prevent serious systemic poisoning. Contact of the Hquid in the eyes of rabbits causes moderately severe injury, but in humans corneal bums have been known to heal within 48 hours. Several human fataUties have resulted from inhalation, dermal contact, or ingestion. One fatahty was caused by exposure to an estimated 300 ppm in air for 2.25 hours. In another fatal case, autopsy revealed pulmonary edema and damage to the Hver, kidneys, and brain (73). 

Diuretics are one of the dmg categories most frequendy prescribed. The principal uses of diuretics are for the treatment of hypertension, congestive heart failure, and mobilization of edema fluid in renal failure, fiver cirrhosis, and ascites. Other applications include the treatment of glaucoma and hypercalcemia, as well as the alkafinization of urine to prevent cystine and uric acid kidney stones. 

Goldberger and Lillie in 1926 found that rats fed certain nutritionally deficient diets developed dermatitis acrodynia, a skin disorder characterized by edema and lesions of the ears, paws, nose, and tail. Szent-Gyorgyi later found that a factor he had isolated prevented these skin lesions in the rat. He proposed the name vitamin Bg for his factor. Pyridoxine, a form of this vitamin found in plants (and the form of Bg sold commercially), was isolated in 1938 by three research groups working independendy. Pyridoxal and pyridoxamine, the forms that predominate in animals, were... 

Leuko trienes are bronchoconstrictive substances released by the body during the inflammatory process. When leukotriene production is inhibited, bronchodilation is facilitated. Zileuton acts by decreasing tire formation of leukotrienes. Although the result is tire same, montelukast and zafirlukast work in a manner slightly differently from that of zileuton. Montelukast and zafirlukast are considered leukotriene receptor antagonists because they inhibit leukotriene receptor sites in the respiratory tract, preventing airway edema and facilitating bronchodilation. 

Mannitol (Osmitrol) is used for the promotion of diuresis in the prevention and treatment of the oliguric phase of acute renal failure as well as for the reduction of IOP and the treatment of cerebral edema Urea (Ureaphil) is useful in reducing cerebral edema and in die reduction of IOE Glycerin (Osmoglyn) and isosorbide (Ismotic) are used in the treatment of acute glaucoma and to reduce IOP before and after eye surgery. 

TH E PATIEN T WITH ED EM A. Fhtients with edema caused by heart failure or other causes are weighed daily or as ordered by the primary health care provider. A daily weight is taken to monitor fluid loss. Weight loss of about 2 lb/d is desirable to prevent dehydration and electrolyte imbalances. The nurse carefully measures and records the fluid intake and output every 8 hours. The critically ill patient or the patient with renal disease may require more frequent measurements of urinary output. The nurse obtains the blood pressure, pulse, and respiratory rate every 4 hours or as ordered by the primary health care provider. An acutely ill patient may require more frequent monitoring of the vital signs. 

The Center for Disease Control and Prevention conducted a randomized epidemiological study on patients who had received morphine nerve paste post-operatively for pain management purposes. Ninety-four percent of the patients used in the cohort presented themselves with surgical-site comphcations such as edema and inflammation 24 days (median) post-operation. Upon culturing of the wounds, 64% tested positive for bacterial infection. It is important to note that aU of the patients were found to have residual morphine paste on board indicative of a chronic morphine state (Sacerdote et al. 2000). 

Acute complications of stroke include cerebral edema, increased intracranial pressure, seizures, and hemorrhagic conversion. In the acute setting, several supportive interventions and treatments to prevent acute complications should be initiated. 

Chronic hepatitis (disease lasting longer than 6 months) is usually associated with hepatitis B, C, and D. Chronic viral hepatitis may lead to the development of cirrhosis, which may induce end-stage liver disease (ESLD). Complications of ESLD include ascites, edema, jaundice, hepatic encephalopathy, infections, and bleeding esophageal varices. Therefore, prevention and treatment of viral hepatitis may prevent ESLD.
