IMPACT OF PRE-OPERATIVE ANEMIA ON POST-OPERATIVE OUTCOME ON PATIENTS UNDER GOING CARDIAC SURGERY

Abstract

Objective: To assess the effect of patient blood management preoperatively on long term chances of survival
and postoperative morbidity after cardiac surgery.
Study Design: Prospective observational study.
Place and Duration of Study: Study was conducted at Armed Forces Institute of Cardiology from June to
October 2014.
Material and Methods: The study was undertaken on 620 consecutive patients undergoing cardiac surgery.
Of six hundred and twenty patients in study population, 196 (31.6%) patients with pre-operative anemia were
compared with 424 (68.3%) non anemic patients. Data was analyzed on SPSS version 17. Ethical approval was
obtained from Institutional Ethical & Review Board of AFIC.
Results: Overall prevalence of preoperative anemia in study population was found to be 38%. Prevalence of
anemia was higher in females as compare to males (52% vs 25% p = 0.001). Duration of stay in ITC (2.5 ± 2 vs 3
± 3.5 p = 0.003), death in OT (2.4% vs 8.85% p = 0.002), and number of blood transfusions (17% vs 48% p =
0.004) were higher in anemic patients as compared to non anemic patients.
Conclusion: In Patient undergoing cardiac surgery Pre-operative anemia was associated with high risk of
deaths, with increase ITC stay and higher number of blood transfusion.
