ABSTRACT
Objective: The aim
of this study is to compare early outcomes in on-pump and off-pump cardiac
surgery.
Methodology: All the patients undergoing CABG surgery were
enrolled after taking informed consent. Demographic and postoperative variables
were entered in the predesigned questionnaire and patients were followed for
early outcomes after surgical procedure.
Results: A total of 470 patients was divided in two groups
235 in ONCAB and 235 in OPCAB.The mean age of
patients was 54.85 ±
9.57 with minimum and maximum age (23-85). There were 400(85.1%) males and
70(14.9%) females. The diabetic patients were 218(46.38%), hypertensive
patients were 271(57.70%), patients having family history of cardiac diseases
were 268(57.02%) smoker patients were 273(58.09%) and hyperlipidemia found in patients
as 210(44.68%). There was a significant difference between Pneumonia (0.014) and
Stroke (0.022) in ONCAB versus OPCAB groups, while the p-values of
neurological dysfunction was insignificant.
Conclusion: The results of current study
showed that early complication in both procedures are nearly same. So we can say both techniques are equally safe and effective.
