Comparison of Awake Craniotomy with Craniotomy Under General Anesthesia for Resection of Tumors in Eloquent Areas of Brain

Objective: To compare awake craniotomy with craniotomy under general anesthesia for early post-operative parameters in patients undergoing resection of tumors in eloquent areas of brain. Study Design: Quasi experimental study. Place and Duration of Study: Department of Anesthesia, Combined Military Hospital, Rawalpindi Pakistan Apr 2021 to May 2022. Methodology: All the patients who underwent resection surgeries for brain tumors in eloquent areas of brain were included in the study. They were divided into two Groups via lottery method. Group A underwent awake craniotomy while Group B underwent craniotomy under general anesthesia. Relevant intraoperative and early post-operative parameters were compared in both the Groups. Results: A total of 60 patients who underwent resection of eloquent area brain tumors in our hospital during the study period were included in the final analysis. Out of these 40(66.7%) underwent craniotomy under general anesthesia while 20(33.3%) underwent awake craniotomies. Mean age of the study participants was 45.61±7.889 years. Frontal lobe tumors were the most encountered brain tumors in our study participants. Patients who underwent awake craniotomy had statistically significantly lower KORNAFSKY score, lesser days of post-operative admission days and lesser neurological deficits (p-value <0.005) as compared to those who underwent craniotomy under general anesthesia. Conclusion: Awake craniotomy emerged as superior option as compared to craniotomy under general anesthesia in terms of early post-operative parameters. Lower KORNAFSKY score, lesser days of post-operative admission days and lesser neurological deficits were seen in patients undergoing awake craniotomy.
