About this study
Official title: Analgesic Effect of Bilateral Quadratus Lumborum Block in the End of Colorectal Laparosopic Surgery: a Prospective Randomized Pilot Study
The primary purpose of COLOQUAL study is to demonstrate the superiority of analgesic effect of a bilateral quadratus lumborum block (QLB), performed at the end of laparoscopic colorectal surgery, compared to standard of care.
The investigators hypothesized that a bilateral quadratus lumborum block performed at the end of laparoscopic colorectal surgery would reduce the incidence of post operative pain, time spent in recovery room, improve patient's satisfaction, and reduce hospitalisation time
Read the detailed description
Visits:
- The patient will arrive in the department the day before the surgical intervention (Day-1). During this preoperative visit (Day-1), the investigator
- will preselect potentially eligible patients
- will offer to participate to this study
- will give the notice form to the patients
- will present the research: objectives, benefits and constraints for the patients
- The intervention day (Day 0):
The investigator will collect the signed consent form after having ascertained the understanding of the notice form by the patient and checking the inclusion and non-inclusion criteria.
The randomization will be done via the eCRF module (allocation group and number) and the preoperative data registration in the eCRF.
Surgical Intervention (Day 1):
All patients will receive standard anaesthesia using sufentanyl, propopol, cisatracurium and sevoflurane. Prevention of nausea and vomiting is performing using Apfel score. Anti microbial prophylaxis is performed according recommendations.
All patients will receive post operative multimodal analgesia using intravenous lidocaine, acetaminophene, ketaminophene, and morphine if NRS (numerating rating scale) > 3 At the end of the surgery, patients in the experimental group will receive a bilateral ultrasound guided quadratus lumborum block with 15 ml of 3,75 mg/mg of ropivacaine. Patients in the control group will not receive the block

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Quadratus lumborum blockProcedure or surgery
- Bilateral Quatratus lumborum block is performed with ultra sound guidance. The high frequency probe is placed right to the umbilicus, and slips laterally to the side to block. It allows showing the three belts of larges muscles of abdomen (External Oblicum, internal oblicum, and transversal of the abdomen). Laterally, these three are merging to from fascia transversalis. Under fascia transversalis, we can see quadratus lumborum muscle. Punction point in lateral, 1cm in the plan separating quadratus lumborum block and fascia transversalis
- 20 ml of ropivacaïne 3.75mg/ml are injected after aspiration test. If in doubt, hydro localisation car be realised.
| Study group | Role | What they receive |
|---|---|---|
| Usual practice | No intervention | Patients receiving a general anaesthesia with propofol, sufentanyl and cisatracurium for the induction, and sevoflurane, sufentanyl and cisatracurium for the maintenance. Patients receiving a multimodal intravenous analgesia, with acetaminophen, ketoprophen and morphine. Antimicrobial prophylaxis is performed according to recommendations |
| QLB block | Experimental | Patients receiving a general anaesthesia with propofol, sufentanyl and cisatracurium for the induction, and sevoflurane, sufentanyl and cisatracurium for the maintenance. Patients receiving a multimodal intravenous analgesia, with acetaminophen, ketoprophen and morphine. Antimicrobial prophylaxis is performed according to recommendations.
In addition, patients receiving a bilateral QLB at the end of the surgery Receives: Procedure: Quadratus lumborum block |
What is being measured
The primary outcome is the main question the study is designed to answer.
Morphine Consumption in milligramme
Once the patient is transferred in post operative surgical service, assessment of the primary outcome will be done by the nurse in charge of the patient
Measured: 8 AM (ante meridiem) the day after surgery
Secondary outcomes (3)
NRS (Numeric rating scale)
Numerating rating score evaluating pain and variating from 0 (No pain) to 10 (Maximum Pain), done by nurses in operating room and in post operative surgical service
Measured: At the entrance of recovery room, at day 1 and Day 2 after surgery
Post Operative recovery: QUO-R4O questionnaire
Quo 40 score is a postoperative recovery score above 200 points (40 is worst score and 200 the best score) validated by Myles et al in 2001.
Measured: At Day 1 and day 15 after surgery
Time spent in recovery room (in minutes)
Assessment of time spent in recovery room (ie: entrance in recovery room until Aldrede score is >9) performed by nurses
Measured: At the output of recovery room ie until 6 hours after intervention
