Brief summary
Post-operative nausea and vomiting (PONV) is common for the patients undergoing laparoscopic gynecologic surgery. PONV is a major factor for patient dissatisfaction, delayed patient recovery and increased medical expenses. Opioid-reducing anesthetic regimen is known to decrease PONV and facilitate early recovery after surgery (ERAS) and has been widely accepted recently. In this study, the researchers intend to investigate whether opioid-free anesthesia effectively reduces PONV, and whether it is clinically safe and feasible.
Interventions
Anesthesia induction: thiopental, rocuronium, desflurane + single dose of alfentanil for endotracheal intubation Anesthesia maintenance: desflurane (without any opioid) Rescue for hypertension, tachycardia: desflurane and beta blocker/calcium channel blocker
Anesthesia induction: thiopental, rocuronium, desflurane + continuous infusion of remifentanil (TCI, Minto model) Anesthesia maintenance: desflurane, remifentanil Rescue for hypertension, tachycardia: desflurane, remifantanil and beta blocker/calcium channel blocker
