Subarachnoid Block Versus Ultrasound Guided Transversalis Fascia Plane Block for Postoperative Analgesia of Inguinal Hernia Repair in Adults

Subarachnoid Block Versus Ultrasound Guided Transversalis Fascia Plane Block for Postoperative Analgesia of Inguinal Hernia Repair in Adults: A Randomized, Double Blinded, Controlled Trial

The aim of our study is to investigate the effect of the ultrasound guided transversalis fascia plane block on the postoperative opioid consumption as a part of multimodal analgesia in patients undergoing inguinal herniorrhaphy under spinal anesthesia.

The aim of our study is to investigate the efficacy of the ultrasound-guided transversalis fascia plane block as a postoperative analgesia as a part of multimodal analgesia in patients undergoing inguinal herniorrhaphy under spinal anesthesia.

The ultrasound (US)-guided transversalis fascia plane (TFP) block was first described by Hebbard in 2009. A local anesthetic (LA) injected between the transversus abdominis muscle, and its deep investing fascia will block the anterior and the lateral branches of the T12 and L1 nerves (4). The efficacy of this block has been demonstrated in iliac crest bone graft harvesting, caesarean section and inguinal herniorrhaphy

Inclusion Criteria:

• Patients undergoing inguinal herniorrhaphy.
• Patients 18-60 years.
• ASA I and II.
• Both sexes.
• Having no contraindication for spinal anesthesia or TFP block.

Exclusion Criteria:

• Refusal of regional anesthesia.
• Infection in the back or at the site of injection for TFP block.
• INR > 1.5.
• Platelet count < 80000 per microliter of blood.
• Patients known to be allergic to amide local anesthetics.
• BMI greater than 35 kgm_2.
• Opioid addiction.
• Have communication problems that may hinder the assessement of pain postoperative.
