ReviewLung function during anesthesia and respiratory insufficiency in the postoperative period: physiological and clinical implications.
This review covers the physiological and clinical implications of lung function during anesthesia and respiratory insufficiency in the postoperative period. We have divided it into 3 main sections: 1) lung function changes induced by anesthesia and surgery, in which the impact on pulmonary mechanics, ventilation/perfusion changes and gas exchange are examined; 2) physiological implications of postoperative respiratory function secondary to decreased alveolar ventilation, development of atelectasis, and interstitial lung edema; and 3) clinical implications of postoperative respiratory failure. In this last section we analyze the current therapeutic modalities available to reduce the incidence of postoperative respiratory failure, as well as related morbidity and mortality.

Traumatic hemipelvectomy is a catastrophic injury resulting from violent blunt shearing forces which cause massive skin, bone, and soft-tissue destruction. The initial extent of the injury as well as the complexity of the consequent problems is staggering. As such it constitutes one of the major challenges seen by trauma surgeons. ⋯ The University of California at Davis General Surgery Trauma Service admitted 9,369 major trauma victims from June 1985 to May 1988. During this 3-year period eight patients sustained a traumatic hemipelvectomy, of whom three survived. Given the complexity, yet rarity, of this injury, a review of the world literature was undertaken to compile collective experiences to aid surgeons in the management of this injury.

Review Case Reports
[Intracerebral hemorrhage immediately following the operation of chronic subdural hematoma].
Complications following the operations for chronic subdural hematoma include recurrence of the hematoma, infection, seizure, and failure of the brain to expand due to cerebro-cranial disproportion. This report presents cases with intracerebral hemorrhage which is relatively rare complication. In case 1, a 35-year-old man developed status epilepticus immediately after the operation for chronic subdural hematoma. ⋯ In case 2, a 78-year-old woman whose CT scan had shown bilateral CSH and brain herniation, demonstrated intracerebral hemorrhage in the medial occipital lobe when examined post-operatively by CT scan. It is possible that the mechanisms of intracerebral bleeding following the operation for CSH are 1) diapedesis through increased permeability of parenchymal blood vessels due to the sudden increase in cerebral blood flow following the existence of longstanding extracerebral mass, and 2) hemorrhagic infarction due to recanalization of posterior cerebral artery compressed by the herniating medial temporal lobe. We should therefore avoid sudden decompression in the management of the cases which showed pre-operative consciousness disturbance or abnormal low or high density on CT scan, because these findings may be preoperative indications of brain fragility.

Review Case ReportsPneumoperitoneum due to peritoneovaginal fistula following hysterectomy.
A patient with pneumoperitoneum that developed due to peritoneovaginal fistula following hysterectomy is presented. In addition, we have reviewed the literature and formulated guidelines for the management of this problem. ⋯ Laparotomy may be avoided if the cause of the fistula is suspected. Surgical closure of the fistula may be unnecessary since spontaneous closure occurs frequently.

Review Comparative Study
A comparison of monobactam antibiotics in surgical infections.
The introduction of gentamicin almost 20 years ago provided an effective option for the treatment of gram-negative bacillary infections. During the past few years, the availability of aztreonam (a monobactam), imipenem (a carbapenem), and newer cephalosporins within vitro activities comparable with aminoglycosides against many gram-negative bacilli, has stimulated a reassessment of the role of aminoglycosides in treating these infections. When determining the role of new antimicrobials as potential replacements for more established agents, the clinical focus should be on three factors: comparative efficacy, safety, and cost. ⋯ The only member of this class currently in clinical use is aztreonam. A comparison with aminoglycosides is particularly relevant because aztreonam is active against aerobic gram-negative bacilli. This review will discuss the acknowledged concerns with aminoglycoside use and compare the characteristics of aztreonam and currently marketed aminoglycosides.
