Sevoflurane Versus Intravenous Anaesthetic Agents in Morbid Obese Patients

Status Recruiting

Clinical Trial Summary

The objective of this prospective randomized clinical study was to compare anesthesia, in morbidly obese patents (BMI >50) who underwent BPD-RYGBP with either sevoflurane or propofol with remifentanyl.

Clinical Trial Description

This is a prospective double blind randomized controlled trial. The patients will be assigned to one of 4 groups (gr): (1) SEVO group, guided by a target end tidal concentration 1 - 2 MAC and modified according to the haemodynamics (BP, HR) of the patients using a bolus inhalation (4 MAC), (2) SEVO-BIS group, using SEVO to a target BIS of 40 - 50, (3) PROPO-REMI and (4) PROPO-REMI-BIS groups accordingly. In groups 1 and 2, anaesthesia will be induced with IV PROPO (2 mg/kg TW [TW = ideal body weight, IBW + 0.4 * difference to the excess weight]), REMI (1 μg/kg IBW) and succinylcholine (1mg/kg IBW). In groups 3, 4 anaesthesia will be induced with a continuous IV PROPO infusion (21mg/kg TW/h for 5 min, 12 mg/kg TW/h for 10 min and then 6 mg/kg TW/h), followed by an IV bolus of REMI and succinylcholine as above. Every rise of BP or HR > 15% of baseline will be followed by a bolus SEVO inhalation in grs 1 and 2 or REMI bolus IV (1 μg/kg IBW) and increase in the continuous infusion rate of REMI from 0.1 to 1.0 μg/kg/min in groups 3 and 4. An epidural catheter will be placed prior to induction for postoperative analgesia only. Intraoperative BP and HR, anaesthetic consumption, recovery scores (Aldrete, Chung, White) and anaesthesia cost will be evaluated. ;
