U/s Guided Oblique Subcostal Transversus Abdominis Plane Block Versus Erector Spinae Plane Block as Preemptive Analgesia

U/s Guided Oblique Subcostal Transversus Abdominis Plane Block Versus Erector Spinae Plane Block as Pre-emptive Analgesia for Open Umbilical Hernia Repair; Randomized, Double-blinded Controlled Trial

Administration of opioids for the treatment of acute pain after open umbilical hernia repair is associated with many side effects. Erector spinae plane (ESP) block is a novel inter-fascial plane block used in postoperative pain and chronic neuropathic pain relief of the thoracoabdominal region.TAP block is a regional injection of local anaesthetic between the transversus abdominis and internal oblique muscle planes. TAP block affects the sensory nerves of the anterolateral abdominal wall (T6-L1) that innervate the abdomen.

TAP block is a regional injection of local anaesthetic between the transversus abdominis and internal oblique muscle planes. TAP block affects the sensory nerves of the anterolateral abdominal wall (T6-L1) that innervate the abdomen. TAP block is an easy technique and decreases postoperative pain and opioid consumption.

Erector spinae plane (ESP) block is a novel inter-fascial plane block used in postoperative pain and chronic neuropathic pain relief of the thoracoabdominal region. However, its first use was for the treatment of chronic pain, but recently it has been used as a postoperative regional analgesia technique in different surgeries from the shoulder to hip regions (3-4) The present study will be carried out to compare the preemptive analgesic efficacy between the ultrasound-guided bilateral ESP block versus bilateral oblique subcostal TAP block on patients undergoing open umbilical hernia repair.
