The patients were divided into 2 groups; Group A (n=15) with total cross clamping, and Group B (n= 15) partial cross clamping and mechanic pulmonary ventilation in cardiopulmonary bypass.RESULTS: Postoperative pulmonary functions were studied in 2 main data; 1) the oxygenization rate of artery blood gas, and 2) spirometer results. Additionally, total cardiopulmonary bypass and total cross-clamping times, extubation times, numbers and types of grafts, days of intensive care unit treatment, and hospitalizations were recorded. There was no statistically significant difference between the 2 groups for oxygenization rate, and surgery hospitalization details. We observed a statistically significant difference with advantage in Group B in spirometric results in terms of healing of pulmonary functions.CONCLUSIONS: Total cross clamping and circulatory arrest of the lungs are the main sources of postoperative pulmonary complications based on the pulmonary inflammatory response in coronary artery bypass surgery.
