Comparison of Regional and General Anesthesia Outcome after Peripheral Vascular Surgery

Background: Compared to other non-cardiac surgical procedures, peripheral vascular surgery is more likely to cause cardiac morbidity and mortality. Planning anesthesia and surgery for open vascular procedures on the lower limbs necessitates a careful examination of the patient's physical capacity and, ideally, includes cardiac and pulmonary evaluation and, if possible, optimization. Methods: An investigation of relationships between anesthesia approach and outcomes of 436 cases (GA=218 and RA=218) was provided by this retrospective, propensity score matched, cohort study. Between May 2019 and July 2021, the study was carried out at the Department of Anaestheology in National Institute of Cardiovascular Diseases and Dhaka Medical College Hospital. Result: In both groups most of the patients (80.7% and 84.4%) were aged less than 80 years. Male participants were more prevalent (57.8% and 60.6%) in both groups. In the GA group, the frequency of both general and surgical problems was considerably higher. The GA group experienced significantly more general medical problems than the control group, including post-operative hemorrhage (1.4% vs. 0.9%), ICU >3 days (0.9% vs. 0.5%), cardiac (2.8% vs. 2.3%), and pulmonary (1.4% vs. 0.9%). After multiple regression analysis, the GA group had a significantly higher 30-day mortality rate and greater instances of all complications. The incidence of general and surgical problems was 6.9% and 3.7%, respectively, and the total 30-day mortality was 3.2%. The average length of stay was 5 (3, 9). The overall one-year amputation rate for the same side was 8.3%. Conclusion: This study highlighted the possibility that RA, as opposed to GA, may be associated with a better outcome following open inguinal and infra- inguinal vascular surgery.
