A Comparison of analgesic efficacy of ultrasound-guided external oblique intercostal plane block and subcostal transversus abdominis plane block, in patients undergoing upper abdominal surgery.

Early postoperative pain that is not adequately managed reduces the quality of recovery and raises the possibility of pulmonary issues following operative procedures, which is a risk factor for the development of chronic pain. The External oblique intercostal plane block is a unique fascial plane block modification that might successfully cover the upper lateral abdomen. In addition to External oblique intercostal plane block’s possible analgesic effectiveness, anticoagulated patients have a significantly decreased risk due to its remote access point from vascular structures. In addition, the block’s superficial technique is preferable to conventional regional operations for obese individuals. For patients experiencing acute pain, the option to put a catheter away from the surgery site without requiring specific patient positioning is also advantageous. In the present study we are comparing the analgesic efficacy of ultrasound-guided external oblique intercostal plane block and ultrasound guided subcostal transversus abdominis plane block, in patients undergoing upper abdominal surgery with subcoastal supraumbilical incisions.
