Incidence and Predictor of Post-Operative Wound Infection in Patients Underwent Coronary Artery Bypass Grafting

Abstract

Objective: To determine the incidence and predictor of postoperative wound infection in patients underwent coronary artery bypass grafting (CPB). Methods:This was a prospective comparative study of 577 patients who underwent cardiac surgery with (CPB) was conducted at cardiac surgery department of Punjab Institute of cardiology, Lahore from 1st March 2012 to 31st March 2017. Consecutive patients undergoing elective and isolated CABG, both genders age ≥20 years, with normal ejection fraction were included in the study Results: Out of 577 patients of which 166(87.83%) were male while 23(12.16%) were female. The mean age of the patient was 53.23 ± 8.43. Incidence of post-operative wound infection in patients underwent coronary artery bypass grafting (CPB) was 73(12.65%). Common co morbid conditions were hypertension 50%, diabetes mellitus (43.5%), smoking (31.1%), hyperlipidemia (20.3%), prior of stoke (12.2%), Prior Surgery (6.8%) and prior renal failure (4.1%), mean CPB time (61.69 ± 32.27), ICU stay 976.03 ± 31.93), mean Cross clamp time(25.27 ± 19.17mg/dl) and Hospital stay (10.16 ± 5.6 day) were more in WI group. Themortality was found to be high in WI group (23.3%). Logistic regression showed that significantly predicted of the post-operative WI were elder age,diabetes mellitus, smoking, family history of IHD, hyperlipidemia, cardiopulmonary bypass time, ICU stay, hospital stay. Conclusion:We can conclude that wound infected patients are at significantly greater risk of incidence, morbidity and mortality after cardiac surgery.

Effects of a telehealth program for wound healing promotion on the wound healing level in patients with diabetes undergoing coronary artery bypass graft surgery: A randomized controlled trial

“…Although the wound usually heals within 21 days or three weeks (Annesley, 2019 ), wound healing is relatively slower in patients with diabetes (Patel et al, 2019 ). Of patients undergoing CABG, 40% have a history of diabetes (Gull et al, 2018 ). Hyperglycemia is correlated with slow wound healing.…”
