Randomized Controlled Trial Clinical Trial
Constant positive airway pressure reduces hypoventilation induced by inhalation anesthesia.
To discover if reducing respiratory system impedance would increase tidal volume and improve ventilation during inhalation anesthesia. ⋯ We conclude that constant positive airway pressure titrated to optimal respiratory system compliance will increase efficiency of inspiratory muscles and improve ventilation. Constant positive airway pressure facilitates a pattern of breathing that minimizes some of the adverse pulmonary effects of inhalation anesthesia.

Randomized Controlled Trial Clinical Trial
Effects of atrial natriuretic peptide at a low dose on water and electrolyte metabolism during general anesthesia.
To assess the hemodynamic, renal, and endocrine effects of small continuous doses of atrial natriuretic peptide (ANP) in patients anesthetized with sevoflurane for gastrectomy. ⋯ Continuous intravenous infusion of ANP at 0.05 microg/kg/min during gastrectomy was associated with greater water and electrolyte excretion unaccompanied by changes in potentially interacting hormones. Low-dose infusion may be particularly safe and useful for controlling water and electrolyte metabolism intraoperatively.

To determine the postoperative outcome of narcolepsy patients, a population that may be at increased risk of perioperative complications, including postoperative hypersomnia, prolonged emergence after general anesthesia, and apnea. ⋯ Pharmacological therapy for narcolepsy should be continued during the perioperative period. In addition, treated narcolepsy patients are at no increased risk for postoperative complications.

Meta Analysis Comparative Study
The effectiveness of rescue antiemetics after failure of prophylaxis with ondansetron or droperidol: a preliminary report.
To compare the effectiveness of treating established postoperative nausea and vomiting (PONV) with an antiemetic acting at a different receptor with that of treating PONV with the antiemetic used for prophylaxis. ⋯ In patients who failed prophylaxis with ondansetron or droperidol, promethazine was significantly more effective than the agent used for prophylaxis for the treatment of PONV. In patients who failed prophylaxis with droperidol, dimenhydrinate was also more effective than droperidol for the treatment of established PONV in the postoperative anesthesia care unit.
