COMPARING THE COMPLICATIONS BETWEEN ON-PUMP AND OFF-PUMP CORONARY ARTERY BYPASS GRAFTING
Ayham Habeb*, Montagab Saleh and Ghanem Ahmad
Background: Off- pump coronary artery bypass grafting surgery(OPCAB) was developed in the hope of reducing perioperative complications related to the use of cardiopulmonary bypass (on –pump). Objective: The present study aims to compare the complications between off pump and the conventional CABG (on pump). Materials and Methods: This is Prospective comparative Study conducted in the Department of Cardiovascular surgery from October 2018 to October 2019. The study included 88 patients who underwent CABG surgery (60 on-pump and 28 off- pump). Results: Of all 88 patients,28 underwent off-pump CABG surgery. There were no significant differences between the groups in terms of age, sex, and co- morbidities. Levels of Hb and PLT were significantly decreased after on- pump CABG surgery :(9.3±1.06 vs. 12.4±1.9 preoperative, p: 0.0001) and (156.4±44.6 vs. 229.06±50.8 preoperative ,p: 0.0001) respectively. Creatinine levels were significantly increased in on- pump CABG surgery(1.32±0.3 vs. 1.07±0.2 preoperative, p:0.006). Compared to off-pump, On- pump CABG surgery was associated with more need for blood product transfusions (4.9±3.5 vs. 1.4±1.2, p: 0.0001), and increased drainage output (1086±414.8 vs. 608.9±179.2, p: 0.0001).The incidence of respiratory failure and bleeding was higher in On- pump CABG: (13.3% vs. 3.6%, p: 0.04) and (18.3% vs. 3.6%, p:0.002), and all deaths were in On -pump CABG. Conclusion: In our study, the off-pump CABG surgery is safe and associated with lower complications compared to the on-pump CABG surgery.[Full Text Article]
