Abstract
This study was planned to show the beneficial effects of prostacyclin (PGI2) on pulmonary function after heparin reversal with protamine. Twenty-eight patients entered the study. Half of these patients received prostacyclin, whereas the other patients did not. N-acetyl glucosaminidase (NAG) level was 37.6 ± 4.7 pmoL/mL in the con trol group and 19.7 ± 3.8 pmoL/mL in the PGI2 group (p < 0.001) five minutes after protamine administration. Leukotriene B 4 (LTB4) level was 118 ±13.7 pmoL/mL in the control group and 56 ± 13.8 pmoL/mL in the PGI2 group (p < 0.001). Alveolar-arterial oxygen difference was 69± 15 mmHg in the con trol group and 58 ± 11 mmHg in the PGI2 group (p < 0.05). As a result of this study it was concluded that PGI2 reduced the toxic mani festations of heparin-protamine complex and improved the pulmonary gas ex change.
