Abstract
Aim : Is to evaluate the effectiveness of Inferior Rectal Nerve block ( IRNB ) in hemorrhoid surgery for post operative ( post op ) pain in the first 24 hours. Aim: The aim is to evaluate the effectiveness of IRNB as analgesic in haemorrhoid surgery in the first 24 hours post op. Methods: Efficacy of IRNB for hemorrhoid surgeries was prospectively evaluated on 200 consecutive patients over 14 months. Patients were divided into 2 groups. 100 patients received LA ( Twenty ml of local anesthetic ( 10 ml 0.25% bupivacaine and 10 ml 1% lignocaine with adrenaline was infiltrated into the anal sphincter under GA ( Group A ) , and 100 patients did not receive IRNB ( group B ). Rescue analgesia in the form of tramadol and diclofenac was available. Duration of analgesia; postoperative pain based on verbal response score (VAS 0-10); and complications were analyzed and recorded. Results: 200 open haemorrhoidectomies were performed. Injection was done just after commencing GA , and 5 minutes onset time allowed before surgery started. Operative time ranged from 10-20 minutes . In Group B, tramadol and diclofenac were administered as rescue analgesia. Post op pain based on VAS was assessed during the next 24hours. Injection site hematoma (1%) was a reported complication in-group A. Conclusions: IRNB is effective, simple and effective analgesia in hemorrhoid surgery.
