Recruiting NA Cardiopulmonary Bypass

New treatment option for Cardiopulmonary Bypass

Official title Optimal Cardiopulmonary Bypass and Anticoagulation Management Strategies in Obese Patients Undergoing Cardiac Surgery

ClinicalTrials.gov ID: NCT03302195

What this study is testing

What is Heparin?

Heparin is an investigational medicine, being studied as a potential treatment for cardiopulmonary bypass.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Standard Heparin management, based on total body weight, is not well established for obese patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). The purpose of this study is to assess the safety and efficacy of using lean body mass (LBM) to determine pump flow rate and/or Heparin dosage in obese patients undergoing CPB.
