Evaluating Propofol Dosing in Obese Patients

Official title: Evaluation of Propofol Dosing Based on Total Body Weight Versus Adjusted Body Weight in Obese Patients Receiving Total Intravenous Anaesthesia With Automated Closed-Loop Anaesthesia Delivery System: A Randomized Controlled Study

Run by Sir Ganga Ram Hospital · NCT05305313 · Data updated 2026-11-12

This study tests whether using total body weight or adjusted body weight for dosing propofol can help keep morbidly obese patients safely anesthetized during long surgeries.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are morbidly obese patients (BMI > 35 kg/m2) scheduled for laparoscopic or non-laparoscopic surgeries lasting more than 60 minutes.

Probably not a fit

Patients with cardiovascular, neurological, or pulmonary disorders, as well as those with uncontrolled diabetes or allergies to propofol, may not benefit from this study.

What this trial studies

This study evaluates the dosing of propofol, an intravenous anesthetic, based on total body weight in morbidly obese patients undergoing surgery. It aims to address the challenges of drug accumulation and potential overdosing that can occur when using standard dosing methods. The study will compare the effectiveness of dosing based on total body weight versus adjusted body weight for maintaining anesthesia during procedures lasting over 60 minutes. By focusing on the unique pharmacokinetics in obese patients, the study seeks to improve anesthesia management and patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective anesthesia protocols for morbidly obese patients.

How similar studies have gone: While propofol dosing based on total body weight has been researched, this specific approach using adjusted body weight for morbidly obese patients is novel and has not been extensively tested.
