Total intravenous anesthesia with spontaneous breathing for transvaginal oocyte retrieval

Abstract

Objective: The aim of this study was to compare the adequacy of spontaneous breathing and assisted ventilation with laryngeal mask 'airway (LMA) during total intravenous anesthesia for transvaginal oocyte retrieval. Methods: One hundred patients, undergoing transvaginal oocyte retrieval under propofol -alfentanil anesthesia were randomly assigned into two groups. Anesthesia was induced with 2 mg.kg-1 propofol and 10 143.kg-1 alfentanil i.v. in all patients . The ventilation was assisted with LMA in group I and was spontaneous in group II. One mg.kg-1 propofol and 5 ng.kg-1 alfentanil i.v. were administered when needed. Systolic and diastolic blood pressure, heart rate, oxygen saturation (SpO2) and end-tidal CO2 pressure (ETCO2), total drug doses administered, side effects and Aldrete recovery score were recorded. Results: Blood pressure and heart rate decreased significantly in all patients after induction (p
