Abstract
Purpose
To evaluate the effect of ultrasound-guided quadratus lumborum block (QLB) preemptive analgesia on recovery in colon cancer patients undergoing open radical surgery and provide reference for its clinical application.
Methods
From July 2019 to June 2020, according to the anesthesia method, 56 patients who received open radical colon surgery were divided into two groups: Group Q (n=27), which received QLB combined general anesthesia, and Group C (n=29), which received general anesthesia only. Both groups were given self-controlled intravenous analgesia pump after surgery. The primary outcome is a series of parameters representing postoperative recovery. The secondary outcome was VAS scores and opioid consumption.
Results
The first time of getting up, flatus, taking semi-liquid diet and the postoperative hospital stay in Group Q were significantly reduced (P<0.01). The rest and active VAS scores were significantly lower in Group Q (P<0.01). The opioids consumption was significantly decreased in Group Q (P<0.05).
Conclusion
The application of ultrasound-guided QLB preemptive analgesia in open radical colon cancer surgery can significantly enhance the postoperative analgesia effect, reduce opioid consumption, and accelerate the postoperative recovery of the patients.
