Comparison of Early-stage Outcomes of Spontaneous Drainage Versus Negative-pressure Drainage Monitoring in Patients Undergoing Coronary Artery Bypass Grafting: a Prospective Randomized Controlled Study

Cardiovascular surgery clinics currently employ drainage monitoring methods involving both negative pressure and non-negative pressure systems. Literature reviews indicate that while drainage monitoring using negative pressure has been evaluated in thoracic surgery studies, it has not been assessed in the context of cardiovascular surgery patients. This study was designed to determine the risk-benefit profile of negative pressure drainage monitoring in patients undergoing open-heart surgery and to ascertain whether negative pressure influences the incidence or volume of postoperative tamponade or pericardial effusion.

Inclusion Criteria: * Patients undergoing coronary artery bypass graft surgery * Age range of 18-80 * Elective operations Exclusion Criteria: * Emergency operations * Patients under 18 and over 80 years of age * Reoperations * Patients with significant preoperative pleural or pericardial effusion * Patients with known coagulopathy
