Brief summary

This prospective, randomized study,control study aims to compare the analgesic effect,opioids consumption,quality of recovery,length of hospital stay,et al. between single-injection QLB(quadratus lumborum block)+ intravenous patient-controlled analgesia (IPCA) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing laparoscopic partial nephrectomy.

Interventions

PROCEDUREsingle-injection TQLB(transmuscular quadratus lumborum block)

Inject 0.6ml/kg local anesthetics in between quadratus lumborum and psoas major under ultrasound guidance

PCIA was initiated using a pump set to deliver boluses of 1.5-2 mg of morphine with a 5-minute lockout interval and no background infusion. The maximal permitted dosage of morphine was set at 8 mg/h.

Design outcomes

Primary

MeasureTime frame
cumulative morphine consumption 8 hours after surgeryat the 8 hours after surgery

Secondary

MeasureTime frameDescription
cumulative morphine consumption at other time points after surgeryat 0, 2, 4, 12, 24 and 48 hours after surgery
The pain scores(at rest or on activity) determined by the numeric rating scale (NRS, 0-10)at 0, 2, 4, 8,12, 24, 48 and 72 hours after surgeryNRS is an internationally recognized pain scale with 11 points ranging from 0 to 10 points, with 0 defined as no pain and 10 defined as the worst pain imaginable.
episodes of nausea and vomitingwithin 24 hours after the surgery
patient satisfaction with anesthesiaat 48 hours after surgeryPatient satisfaction with anesthesia was assessed using a 5-point scale (5: very satisfied; 4: satisfied; 3: neither satisfied nor dissatisfied; 2: dissatisfied; 1: very dissatisfied)
time of recovery of bowl movementwithin the 5 days after surgerytime from the end of the surgery to the first time of bowl movement
quality of recovery evaluated by the self-assessment 15-item quality of recovery (QoR) scaleat 72 hours and 120 hours after the sugeryQoR is a 15-item questionnaire which will score on a scale of 0-10 pertaining to patient's comfort, support system, pain, well-being, and ability to carry out daily activities, where 0 indicates none of the time and 10 indicates all of the time
postoperative length of hospital staywithin 2 weeks after the surgerytime to patient's discharge
ambulation timewithin the 5 days after surgerytime from the end of the surgery to the first time to out-of-bed activity
