Comparative Evaluation of Pudendal Nerve Block with Local Anesthetics And Methylene Blue versus Saddle Block in Benign Perianal Surgery – A Prospective, Randomized Study

Objective: The present study was conducted to compare SEPTA block technique with SADDLE anesthesia in benign Anorectal diseases. Methods: A prospective randomized comparative study was performed with 30 patients in each of two groups. Patients in Group A received SEPTA block and in Group B received Saddle anesthesia. Comparison was done between two groups in terms of total amount of drug given, average time of starting surgery after anesthesia, average duration of operation, average time of giving first rescue analgesia, average time of ambulation and post operative VAS score after 4 and 12 hours of benign perianal surgery. Results: In this study average amount of the drug given was 30 mL in Group A and 2 mL in Group B. Average time of starting surgery after giving anesthesia was 3.5 minutes in Group A and 8.5 minutes in Group B. First rescue analgesia was required average 220 minutes after surgery in Group A and 125 minutes after surgery in Group B. Average time of ambulance after surgery was 45 minutes in Group A and 240 minutes in Group B. Comparison of post operative VAS score after 04 hours and 12 hours was not statistically significant between two groups. In Group A 01 patients developed urinary retention while in Group B 03 patients were developed urinary retention. In Group B 03 patients developed headache while in Group A none of the patients had headache. Conclusions: The SEPTA technique offers the benefits of quick onset, long lasting analgesic effect, early mobilization, and less complications as compared to SADDLE block Anesthesia. As a result, it can serve as an alternative to Saddle Block anesthesia for benign anorectal surgeries.
