Background: Bleeding is a major concern after cardiac surgery and also a significant cause of morbidity and mortality. Postoperative mediastinal bleeding in patients undergoing cardiac surgery is still one of the most common complications.
Objective: To find out Outcome of Plasma Fibrinogen Level and Postoperative Bleeding Following OPCAB Surgical Patients. Methods: This comparative cross-sectional study was carried out at the Department of Cardiac Surgery in BSMMU hospital from March, 2017 to August, 2019. The study population was 60, with 2 (two) groups having 30 patients in each. Patients from both the groups underwent OPCAB. Statistical analysis of different characteristics between the patients of both groups was done to draw a conclusion.
Results: This study total sixty (60) patients who underwent off-pump coronary artery bypass graft surgery were evaluated in this study. Postoperative care at ICU was given to the patients of both groups as per standard hospital protocol. The findings of the study obtained from data analysis presented in the following pages. Among the study population mean age in group A was 55.43±8.53 years and in group B was 59.63±6.86 years. The difference in age between two groups was statistically significant (p<0.05). There was no statistical significance of gender between the two study groups (p>0.05). The mean BMI in group A was 24.13±2.49 kg/m² and that in group B was 24.62±3.71 kg/m². The findings were statistically not significant (p>0.05). Shows the comparison of postoperative variables between group A and B patients. Amount blood loss in 1st 12 hours immediate after surgery in group A and B were 185.67±35.20 ml and 219.67±57.32 ml respectively. Post-operative blood transfusion in group A and B were 2±0.53 units and 2.5±0.68 units respectively, which was statistically significant (p<0.05. There were no postoperative thromboembolic events, cardiac ischemic incidents, re-exploration and mortality. The most valuable predictor for increased postoperative bleeding after OPCAB.
Conclusion: In conclusion the efficacy were no postoperative thromboembolic events, cardiac ischemic incidents, re-exploration and mortality. Pearson co-efficient correlation test showed an inverse relationship between plasma fibrinogen level and postoperative bleeding following OPCAB. Fibrinogen concentration level was associated with increased postoperative bleeding in patients undergoing off-pump coronary artery bypass grafting surgical patients.
