Overview
Brief Summary
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
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

Outcomes
Primary Outcomes
Morphine Consumption in milligramme
Time Frame: 8 AM (ante meridiem) the day after surgery
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
Secondary Outcomes
- NRS (Numeric rating scale)(At the entrance of recovery room, at day 1 and Day 2 after surgery)
- Post Operative recovery: QUO-R4O questionnaire(At Day 1 and day 15 after surgery)
- Time spent in recovery room (in minutes)(At the output of recovery room ie until 6 hours after intervention)
