In evaluating and preparing patients with both liver and pulmonary dysfunction, a number of factors must be considered inthe choice of anesthetic drugs and techniques, both inthe intraoperative and postoperative periods. Our contributors emphasize theimportance of creful evaluation of tests of pulmonary and hepatic functions,making every effort to correct deficiencies prior to anesthesia.In weighing the risks of intraoperative and postoperative hepatic versus pulmonary problems, the authors generally prefer a potent inhalation anesthetic such as halothane or enflurane to prevent bronchoconstriction, since pulmonary insufficiency is considerably more frequent than significant hepatic dysfunction.
