Intertransverse Process Block for Quality of Recovery Post-Open Hepatectomy

The study aims to assess the analgesic efficacy of the ITPB at the retro-SCTL space in patients undergoing major open hepatectomy surgery. This is assessed by: Primary Objective: Primary outcome measure: ● Assessing the quality of recovery 15 (QoR15) score at 24 and 48 hours Secondary outcome measure: * Number of anaesthetic and hypoesthetic dermatomes on the ventral and dorsal aspect of the thorax on both the sides at 30 minutes of block completion and during the post anaesthetic room (PACU) discharge * Assessing the 24-hour area under the curve of postoperative pain numerical rating score (NRS, 0-10) at rest and deep breathing or upon use of triflow. * Assessing the amount of postoperative morphine (mg) equivalent consumption at 24 and 48 hours * Time to discharge from High dependency unit (HDU) or Intensive care unit (ICU) Hypothesis: The investigators hypothesize that the application of ITPB targeting the retro-SCTL space in patients undergoing open hepatectomy will improve overall quality of recovery and pain score.
