Postoperative revision surgery for bleeding in a tertiary heart center

Area of Science:

• Cardiovascular Surgery
• Critical Care Medicine
• Surgical Outcomes Research

Background:

• Re-exploration for bleeding is a significant concern following open heart operations.
• Understanding risk factors for mortality and morbidity is essential for improving patient care.

Purpose of the Study:

• To identify risk factors associated with mortality and morbidity in patients undergoing re-exploration for bleeding after open heart surgery.
• To compare outcomes between early and delayed re-exploration groups.

Main Methods:

• Analysis of 282 patients re-explored for bleeding after 19,680 open heart operations (January 1995 - January 2009).
• Patients were categorized into early (same day) and late re-exploration groups.
• Comparison of mortality, total morbidity, and transfusion requirements between groups.

Main Results:

• Overall mortality was 8.5%.
• Delayed reoperation was associated with significantly higher mortality and morbidity.
• Significant predictors of mortality included old age, female sex, left ventricular dysfunction, noncoronary operations, and delayed reoperation.
• Predictors of morbidity included old age, preoperative dialysis, tobacco use, chronic lung disease, and delayed reoperation.

Conclusions:

• Early re-exploration for bleeding after open heart surgery is associated with better outcomes.
• Risk factors for mortality and morbidity are multifactorial, with delayed reoperation being a key adverse predictor.
• Further research may focus on optimizing timing and management strategies for re-exploration.
