Transversus Abdominis Plane Block Versus Ilioinguinal Nerve Block for Pain Management in Inguinal Herniorraphy

Comparison of Efficacy of Transversus Abdominis Plane Block and Ilioinguinal Nerve Block for Postoperative Pain Management in Patients Undergoing Inguinal Herniorraphy With Spinal Anesthesia

This study compares efficacy of transversus abdominis plane block and ilioinguinal nerve block for postoperative pain in patients undergoing inguinal herniorraphy with spinal anesthesia. One-third of the patients will receive standard postoperative pain regimen(control group), one-third will receive a transversus abdominis plane block (with ultrasound guidance) and the last group will receive an ilioinguinal nerve block(with ultrasound guidance) in addition to standard postoperative pain regimen. This study is a Randomized prospective open-label controlled study.

Inclusion Criteria:

• patients over 18 years old
• having ASA (American Society of Anesthesiologists) 1 or 2 physical status score preoperatively
• not having a neuromuscular disease
• scheduled for elective single sided inguinal herniorraphy operation

Exclusion Criteria:

• being under 18 years of age
• patient refusal
• having a neuromuscular disease or sensorial neurological deficit covering similar area of effect with peripheral nerve block interventions or the surgical site
• having ASA 3 or 4 physical status score preoperatively
• having one of the contraindications to spinal anesthesia and/or to peripheral nerve blocks as listed by NYSORA (New York School of Regional Anesthesia)
• having emergency surgery or scheduled for bilateral inguinal herniorraphy
