Anesthesic Propofol and Remifentanil Requirements in Obese Patients (LoopObese)

This study has been terminated.
(difficulty in recruiting)
Sponsor:
Information provided by (Responsible Party):
Hopital Foch
ClinicalTrials.gov Identifier:
NCT00779844
First received: October 23, 2008
Last updated: September 22, 2016
Last verified: September 2016
  Purpose
Pharmacokinetic models for anesthetic agents are questionable. The objective of the study is to compare the propofol and remifentanil doses required to maintain the bispectral index in the range 40-60 in two groups of patients: obese patients and lean patients

Condition Intervention Phase
Anesthesia Obesity Procedure: bariatric coelioscopic surgical procedure Procedure: supra-umbilical coelioscopic surgical procedure Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Intravenous Anesthesia in Obese Patients: Propofol and Remifentanil Requirements

Further study details as provided by Hopital Foch:

Primary Outcome Measures:
  • Dose of propofol administered [ Time Frame: intraoperatively ]

Secondary Outcome Measures:
  • remifentanil requirement, hemodynamic profile, time to extubation, performances of the automated system of propofol and remifentanil deliver [ Time Frame: intraoperatively ]

Enrollment: 63
Study Start Date: December 2008
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
obese patients
Procedure: bariatric coelioscopic surgical procedure
total intra-venous anesthesia (propofol and remifentanil) being delivered using a close-loop system with the Bispectral Index as the single input for the controller
Active Comparator: 2
lean patients
Procedure: supra-umbilical coelioscopic surgical procedure
total intra-venous anesthesia (propofol and remifentanil) being delivered using a closed-loop system with the Bispectral Index as the single input for the controller
