Background: Heparin is an anticoagulant used invariably in all cardiac surgery. Intermittent heparin dosing after initial bolus dose is widely practiced to maintain ACT level 200-300 seconds in OPCAB. Fluctuation of ACT level from this range may causes adverse postoperative outcome. This study was aimed to compare early postoperative outcome between intermittent heparin dose and continuous heparin infusion after initial bolus dose during OPCAB. Methods: In this comparative experimental study total 110 patients were enrolled by purposive sampling and divided into 2 groups: group-A where 55 patients received intermittent heparin after initial bolus dose and group-B where 55 patients received continuous heparin infusion after initial bolus dose. Post operative outcomes were compared in both groups. Results: Baseline ACT level of group-A was 87.04±5.51 seconds and group-B was 87.31±5.74 seconds (p = 0.800). After bolus dose of Heparin, ACT level of group-A was 252.02 ± 25.131 seconds and group-B was 259.04 ± 12.645 seconds (p = 0.068). Mean maintenance ACT was 326.34±22.774 seconds in group-A and 258.67±12.285 seconds in group-B patient (p<0.001). Peroperatively 29% from group-A and 11% from group-B developed arrhythmia. Postoperative mean Troponin I level in group-A was 5.78± 1.15 and group-B was 5.32± 1.05 ng/dl (p = 0.030). Postoperative blood loss was significantly higher in group-A than group-B (986.36± 398.31 ml vs 852.73±241.22 ml, p=0.036). There was significantly better reduction of arrhythmia and ischemia in postoperative and on discharge ECG finding in group-B patients (p=0.002). On discharge echocardiography 31% from group-A and 13% from group-B had regional wall motion abnormality (p=0.018). But there was no significant difference in LVEF% (52.65±5.99 vs 53.85±5.77, p = 0.287). There was only one mortality which was from group-A. Conclusion: Early postoperative outcome of continuous heparin infusion is better than intermittent intravenous heparin after initial bolus dose during Off-pump coronary artery bypass surgery. So, during OPCAB use of continuous heparin infusion after bolus dose is eminent time worthy. [ABSTRACT FROM AUTHOR] |
