Effects of Continuous Positive Airway Pressure (CPAP) Ventilation During Cardiopulmonary Bypass on Postoperative Outcomes

Abstract

Objective: In this study, the relationship between the duration of intensive care unit stay, hospital stay, and intubation times between nonventilated and continuously ventilated groups of patients who underwent surgery with a cardiopulmonary bypass (CPB) device was investigated.
 Methods: In the study, we divided patients into two groups. Continuously ventilated during CPB group and non-ventilated group. In the continuously ventilated group, respiratory rate was 6 per minute, tidal volume was 6 ml/kg and FiO2 was 50%. In the non-ventilated group, the lungs were completely removed from the ventilator after the cross-clamp was placed.
 Results: Although the duration of intensive care unit stays, length of hospital stay, and intubation times were relatively short in the continuously ventilated group, there was no statistically significant difference between the two groups. 
 Conclusion: There is a need for new studies on continuous ventilation during CPB to be designed based on subgroups and larger volumes.
