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:
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.

| Quality of Recovery (QOR-15) | The QoR-15 scale is a global measure of postoperative recovery, with a score ranging from 0 (extremely poor QoR) to 150 (excellent QoR). The QoR-15 has since become the most widely reported measure of patient-assessed QoR after surgery. QoR-15 has no units. | 24 and 48 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Dermatomal blockade on Thorax 30 minutes upon block completion | To assess the 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. This will be done by ice block test. The blockade is considered positive if patient has a reduction in cold sensation over the tested dermatome compared to non-blocked areas such as forehead. |
