Kalp Cerrahisinde Yüksek Vücut Kitle İndeksinin Morbidite ve Mortalite Üzerine Etkileri.

Objective: In this study, we evaluated the effects of body mass index on mortality and morbidity after cardiac surgery. Method: The record of 813 patients who performed open-heart surgery in our clinic were retrospectively analyzed. 505 patients with complete records were included in the study. Postoperative mortality and morbidity developments were compared in patients with a body mass index of (BMI) ≥30 kg/m2 and BMI ≤30 kg/m2 from the records. Results: 389 (%70) of patients were BMI < 30 kg/m2, non-obese (Group N), 166 of them were BMI ≥30 kg/m2, obese (Group OB). The mean age of groups (59.2±12.5, 59.6±9.6 years, respectively, p=0.65) was similar. Female gender, Diabetes Mellitus (DM), hypertension, hyperlipidemia were more common in Group OB (p<0.05). Intraoperative cardiopulmonary bypass (101±43, 98±42 p=0.26) and the duration of aortic cross clamp (64±32.7, 61.6±32.5 p=0.21) were similar. Post-operative complications of pulmonary (%19, %10) and renal (%13, %9) were significantly higher in Group OB (p<0.05), tamponade (%3.1, %0.6) and bleeding revision (%5.7, %1.8) were higher in Group N (p<0.05). Mortality occurred in 27 (5%) patients after surgery. There was no significant difference between mortality rates, ICU and hospital stay (p<0.05). Conclusion: High BMI (≥30 kg/m2) is associated with respiratory system and renal complications after cardiac surgery, and low BMI (< 30 kg/m2) is associated with morbidities such as tamponade and bleeding revision.
