Intertransverse Process Block for Quality of Recovery Post-Open Hepatectomy (ITPB QoR)

April 25, 2025 updated by: Wing Sum Li, Chinese University of Hong Kong

Effect of Intertransverse Process Block on the Quality of Recovery Post-Open Hepatectomy: A Pilot Non-Randomised Study of Intervention

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Quality of Recovery (QOR-15)
Time Frame: 24 and 48 hours
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

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dermatomal blockade on Thorax 30 minutes upon block completion
Time Frame: Up to 30 minutes after 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.
Up to 30 minutes after block completion
24 hours area under curve of postoperative pain score
Time Frame: Up to 24 hours
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.
Up to 24 hours
Morphine consumption at 24 and 48 hours postoperatively
Time Frame: At 24 and 48 hours postoperatively
Assessing the amount of postoperative morphine (mg) equivalent consumption at 24 and 48 hours
At 24 and 48 hours postoperatively
Time to discharge from HDU / ICU
Time Frame: Up to 5 days
Time to discharge from High dependency unit (HDU) or Intensive care unit (ICU) up to 5 days
Up to 5 days
