Role of Ultrasound Guided Transversus Abdominis Plane Block in Pain Control After Hepatectomy

Inadequately managed acute pain following abdominal surgery originates from somatic pain signals in the abdominal wall and is linked to various unfavorable postoperative outcomes. These consequences encompass patient distress, respiratory complications, delirium, myocardial ischemia, extended hospital stays, an elevated risk of chronic pain, heightened analgesic consumption, delayed bowel function, and an increased need for rescue analgesics. This study aims to assess the postoperative analgesic efficacy of ultrasound-guided Transversus Abdominis Plane (TAP) block using oblique subcostal and posterior approaches in hepatectomy.
