This review examines the principles and practice of antibiotic prophylaxis in surgery. Such prophylaxis is required to decrease the frequency of postoperative infection in most patients with clean-contaminated and contaminated wounds, to prevent infrequent but devastating infection of prostheses in cardiovascular and orthopedic surgery and to prevent endocarditis in noncardiac surgery in patients who have valvular heart disease. Prophylaxis should begin before operation; it is usually unnecessary afterwards. ⋯ The latter is more certain, but oral prophylaxis in bowel surgery may offer additional protection by reducing colonic flora, and topical wound and peritoneal antibiotics may be augment protective antibiotic levels at those sites. Antibiotics, such as the cephalosporin cefazolin (but not cephalothin), which penetrate blood and tissues rapidly and for prolonged periods, afford excellent prophylaxis at most sites. But for prophylaxis in colonic surgery, antibiotics directed against Bacteroides fragilis may be superior, and to prevent endocarditis in noncardiac surgery, vancomycin or a combination of penicillin and an aminoglycoside is best.

Hyperventilation, ventricular drainage, and mannitol remain the mainstays of the treatment of cerebral edema not amenable to or following surgical therapy. There appears to be good therapeutic rationale for the use of "low-dose" mannitol in more prolonged treatment of intracranial hypertension (Table 5.1). ⋯ Certainly, the "ideal" agent for the treatment of cerebral edema, one that would selectively mobilize and/or prevent the formation of edema fluid with a rapid onset and prolonged duration of action, and with minimal side effects, remains to be discovered. In the meantime, research to refine the use of the older agents and determine the usefulness of the newer ones should be encouraged.

ReviewPostoperative chest radiograph: I. Alterations after abdominal surgery.
Postoperative cardiopulmonary complications remain a major cause of mortality and morbidity despite recent advances in intra- and postoperative management. The chest radiograph is a valuable aid in evaluating them. This paper reviews the major chest radiographic alterations after abdominal surgery and attempts to place them in clinical perspective.
