Brief summary

This study aims to assess whether transmusculr quadratus lomborum block (QL block) can reduce postoperative pain after cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS and HIPEC). Patients will be randomly assigned to either QL block group or control group. Ultrasound-guided bilateral transmuscular quadratus lomborum block will be performed in QL block group using 0.375% ropivacaine. Multimodal analgesic regimen including acetaminophen, nonsteroidal antiinflammatory drugs (NSAIDs), and rescue opioids will be used in every patient. Primary outcome is opioid consumption for 24 hours after surgery. Secondary outcomes included pain scores, time to first rescue analgesics, quality of recovery score, length of hospital stay.

Detailed description

Adult patients scheduled to undergo cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy will be screened for eligibility. After induction of general anesthesia, ultrasound-guided bilateral transmuscular quadratus lomborum block will be done in QL block group. 0.375% ropivacaine will be injected to each side. Patients in control group will receive no block. Multimodal analgesia will be applied to every patient for postoperative pain control. Multimodal analgesic regimen included scheduled administration of acetaminophen, NSAIDs, and rescue opioids. Blinded investigator will assess pain scores at rest and on movement at 6, 12, 24, 48, 72 hours after surgery, analgesic consumptions, nausea, vomiting, and quality of recovery questionnaire.

Interventions

PROCEDUREArm I (QL block and multimodal analgesia), Arm II (multimodal analgesia without regional block)

Arm I (QL block and multimodal analgesia): Bilateral transmuscular QL block will be done. Postoperative multimodal analgesia including administration of acetaminophen, NSAIDs,nefopam, and rescue opioids Arm II (multimodal analgesia without regional block): No block will be done. Postoperative multimodal analgesia including administration of acetaminophen, NSAIDs, nefopam, and rescue opioids

Quality of Recovery Questionnaire (15-item Quality of Recovery)At post-operative 72 hoursEach item uses an 11-point numeric rating scale. The sum of the scores of the 15 items ranges from 0 to 150, with a high score indicating good quality of recovery.
Pattern of injectate spread on ultrasonographyDuring quadratus lumborum (QL) block procedurePattern of injectate spread on ultrasonography
Numeric rating scale at post anesthetic care unit (PACU)30 minutes after the end of operationNumeric rating scale at post anesthetic care unit. Numeric rating scare is 11-point scale from 0 to 10. The higher the number, the more severe the pain (0 is no pain at all, 10 is the most severe pain imaginable).
