ABSTRACT
Objective: The aim of this study is to compare in
hospital morbidity and mortality in on pump versus off pump CABG.
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 wasdivided in two groups 235 (on pump and off pump).The mean age of patients was 54.85 ±
9.57 (23-85).There were 400(85.1%) males and 70(14.9%) females. The total
data of 470 patients was divided in two groups 235 in on Pump and 235 in off
pump CABG.The mean age of patients was 54.85 ± 9.57 (23-85). There were
400(85.1%) males and 70(14.9%) females. Different
clinical outcomes were compared in both groups (On-Pump versus Off-Pump CABG)
by using Euro Score, we found Peripheral Disease in On-Pump CABG group compared
with Off-Pump CABG as 11(4.68% vs 12(5.11%) with p-value=0.831 which was
statistically insignificant, current data assessed lung disease in both groups
as 11(4.68%) vs 13(5.53%) with statistically insignificant p-value (0.675). and
unstable angina
were 12(5.11%, p-value 1.00) patients founded and Peri and post myocardial
infarction also assessed in
both groups with p-value (0.74 &
1.20). respectively.Data regarding in hospital mortality was analyzed and found
that 7(2.98%) in on pump group compare with off pump group was According to our research mean number of
grafts placed in On-Pump CABG were 9(3.83%) with statistically insignificant p-value (0.611).
Conclusion:Proof is presented that surgery on beating
heart (Off-Pump) is as safe and effective as Conventional CABG, and cheaper
than conventional surgery. However, it is uncertain whether the cost savings
are sustained over a longer period of time.
