Diaphragmatic elevation after cardiac surgery may result in compromized post operative respiratory function, prolonged ventilator use, longer intensive care unit (ICU) stays, poor quality of life and even mortality. 200 patients receiving open-heart surgery during the two years from October 1990 to October 1992 were studied retrospectively. 26 patients developed postoperative diaphragmatic elevation (Group 2). On the other hand, 174 patients did not (Group 1). The mean age of Group 1 (37.3 +/- 20.0 years) was younger than that of Group 2 (57.4 +/- 9.1 years), P < 0.0001. The mean aortic cross-clamp time was 70.1 +/- 38.1 minutes in Group 1. On the other hand, Group 2 had a longer crossclamp time (84.5 +/- 31.3 Minutes), p < 0.03. Our study revealed that the patients who suffered post operative diaphragmatic dysfunction were older and had a longer aortic crossclamp time than the patients who did not.
