Abstract

Objectives: To compare the efficacy of perianal block versus spinal anesthesia in patients undergoing perianal procedures.

Study Design: Quasi-experimental study.

Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, from Sept 23 to Feb 24.

Methodology: 56 patients who were planned to undergo elective perianal surgery were included in the study and were divided into Perianal Block Group (Group-A) and Spinal Anesthesia Group (Group-B) alternatively in order of presentation. Intra-operative and post-operative anesthesia related outcomes were assessed and compared between groups. Data was analyzed by SPSS 20.00.

Results: Mean age was 34.98±8.32 years. There were 37(66.07%) males and 19(33.93%) females. Most commonly performed perianal surgeries were fistulotomy 17(30.36%) and fistulectomy 17(30.36%) followed by hemorrhoidectomy 14(25.00%) and lateral internal sphincterotomy (LIS) 8(14.29%). Mean duration of anesthesia onset in perianal block group was 2.60±0.83 minutes while in spinal anesthesia group it was 5.96±1.29 minutes, (p<0.001). Mean duration taken to ambulate in perianal block group was 18.28±4.05 minutes while in spinal anesthesia group it was 248.71±41.67 minutes, (p<0.001). Mean duration for which patients remained pain free in perianal block group was 269.60±31.11 minutes while in spinal anesthesia group it was 138.82±15.23 minutes, (p<0.001).

Conclusion: Perianal block is much better and more efficacious option for regional anesthesia as compared to spinal anesthesia (SA) in patients who undergo perianal surgeries without spinal anesthesia associated with complications like headache and hypertension.
