(CCABG) Vs (OPCABG)

CONVENTIONAL CORONARY ARTERY BYPASS GRAFTING Vs OFF-PUMP CORONARY ARTERY BYPASS GRAFTING; COMPARISON OF POST OPERATIVE PARAMETERS

Abstract

Objectives: The objectives of this study were to compare Off-pump CABG with Conventional CABG regarding; a). Duration of
postoperative mechanical ventilation, b). Amount of postoperative bleeding, c). Volume of blood and blood product transfusions,
d). Total stay in intensive care unit (ICU). Setting: Study was done at Post operative Intensive Care of a Tertiary Care Cardiac
Hospital (AFIC/NIHD) Rawalpindi. Design & Methods: Study was a non interventional comparative study. Data were collected
using a convenient sampling.The patients fulfilling the inclusion and exclusion criteria were selected as subjects. On compilation
in tabulated form the results were analyzed using statistical program for social sciences (SPSS-8). Student’s t Test was applied
and significance was defined if p value was less than 0.05. Period: First forty two patients undergoing conventional CABG
(CCABG) starting from 1 Jan 2001 onwards were included in group I and similarly first 42 patients undergoing Off pump CABG st
(OPCABG) from the same date were included in group II. Results: Patients in OPCABG group had significantly reduced time of
mechanical ventilation and decreased bleeding thus requiring less number of blood and blood products units. OPCABG group
also had significantly shorter stays in intensive care unit in comparison of CCAG. Conclusion: By avoiding cardiopulmonary
bypass (CPB) circuit in selected patients we can reduce the duration of ventilation, total blood loss and thus blood product
transfusions. Total stay in ICU post operatively could also be reduced.
