BackgroundNo administration of supplemental muscle relaxants may be beneficial to the recovery of the ambulatory laparoscopic surgery. For this study, we compared the cardiorespiratory factors during propofol and remifentanil anesthesia for laparoscopic pelvic surgery (LPS) with or without supplemental muscle relaxants.Materials And MethodsIn total, 56 healthy female patients scheduled to undergo laparoscopic pelvic surgeries were randomly assigned to two groups (A and B). Anesthesia was induced with lidocaine 30 mg, propofol target organ concentration 5.0 microg/mL, remifentanil 3.0 ng/mL, and rocuronium 0.6 mg/kg intravenously (i.v.). After tracheal intubation, anesthesia was maintained with 2.0-5.0 microg/mL of propofol and 1-4 ng/mL of remifentanil i.v. All the patients' lungs were mechanically ventilated in both groups and intermittent bolus doses of rocuronium (0.15 mg/kg i.v.) were administered in group A-however, not in group B. Heart rate (HR) and systolic arterial pressure (SAP), diastolic arterial pressure (DAP), end-tidal carbon-dioxide concentration (EtCO(2)), peak inspiratory pressure (PIP), expired minute ventilation (MV), intra-abdominal pressure (IAP), and temperature were measured during the pneumoperitoneum.ResultsThere were no group differences in HR, SAP, DAP, EtCO(2), PIP, IAP, MV, PaO(2), PaCO(2), and temperature between groups A and B.ConclusionsNo supplemental muscle relaxants are required during propofol and remifentanil total i.v. anesthesia for LPS.
