Postoperative outcome is effected by the perioperative status of patients.
Optimization of preoperative pulmonary function results in a decrease in postoperative morbidity and mortality. Another factor which contributes to improvement in postoperative outcome is increased quality of acute pain control. The application of non-narcotic based drugs in conjunction with opioids delivered via innovative techniques leads to increased patient satisfaction and shortening of postoperative stay. The avoidance of unpleasant side effects of anesthetic drugs shortens the length of patient stay in the recovery room and lowers overall cost for hospitalization. Pressure support improves efficency of spontaneous breathing during inhalation anesthesia.
