No results posted yet for this study

Summary

The aim of this study was to investigate whether robot assisted laparoscopic radical prostatectomy give rise to the impairment of diaphragmatic function postoperatively, and whether combined general/epidural anesthesia could provide better postoperative diaphragmatic function.

Conditions

Interventions

DRUG

epidural 250mL of 0.2% ropivacaine and 2 μg/mL of fentanyl, 5 mL/hr continuous infusion and 0.5 mL bolus dose

Before the induction of anesthesia, epidural catheter was inserted in group GE at T8/9, T9/10, or T10/11 interspinous space with a 17-gauge Tuohy needle in lateral decubitus position and advanced 5 cm cephalad. . Epidural analgesia was maintained using the patient-controlled analgesia technique containing 250 mL of 0.2% ropivacaine and 2 μg/mL fentanyl with setting of 5 mL/hr for continuous infusion and 0.5 mL of bolus dose. Lockout time was set to 15 min. General anesthesia was induced with 2 mg/kg of propofol and 50 mg of rocuronium. After tracheal intubation, anesthesia was maintained with sevoflurane. All the patients were ventilated with controlled mode of 8 mL/kg of ideal body weight and respiratory rate was adjusted to maintain end-tidal carbon dioxide between 35-40 mmHg.

DRUG

no epidural drug administered

Patients allocated to general anesthesia group and DID NOT receive epidural anesthesia. General anesthesia was induced with 2 mg/kg of propofol and 50 mg of rocuronium. After tracheal intubation, anesthesia was maintained with sevoflurane. All the patients were ventilated with controlled mode of 8 mL/kg of ideal body weight and respiratory rate was adjusted to maintain end-tidal carbon dioxide between 35-40 mmHg.
