Obesity surgery
-
According to physical impairments of massive obesity, cardiac, respiratory and gastrointestinal physiology must be considered as much as pharmacokinetic behavior. Anesthetic management of morbidly obese patients has to be carefully planned, in order to minimize the increased risks of aspirative pneumonitis, hemodynamic instability and delay in recovery. The ideal anesthesia should provide a smooth and quick induction, allowing rapid airway control, prominent hemodynamic stability, and rapid emergence from anesthesia. To approach these ideal conditions, a Total Intravenous Anesthesia (TIVA) with midazolam, remifentanil, propofol and cisatracurium was designed and analyzed. ⋯ TIVA with midazolam, remifentanil, propofol and cisatracurium was found to be effective, secure, predictable and economic for the anesthetic management of morbidly obese patients.
