Evaluation of Post Cardiopulmonary Bypass Complications Related to Aortic Cross Clamp Time in Cardiac Patients from Selected Hospitals of Lahore-Pakistan

Abstract

In this study the frequency and mortality of pulmonary complications have been investigated after cardiopulmonary bypass related to aortic cross clamp time. High rate of pulmonary complication (58%) has been reported by international journal of surgery. This was a cross-sectional study included 120 patients, which were between 16 to 78 years, with predominant male participants. The research was conducted at Punjab Institute of Cardiology and Gulab Devi Hospital, Lahore. The results revealed that about 51(42%) patients had post-operative pulmonary complication due to prolonged aortic cross clamp time (more than 90 minutes), while 37(30%) patients had pleural effusion, 22(18%) patients had prolonged mechanical ventilation, 3(2.5%) patients suffered from pneumonia and 1(0.83%) patient were suffered from pulmonary edema. It was concluded that prolonged aortic cross clamp time (> 90 minutes) is the most predominant post-operative pulmonary complication as compared to pleural effusion and prolonged mechanical ventilation.
