Application of dexmedetomidine combined with ropivacaine for quadratus lumborum block at the lateral supra-arcuate ligament in open hepatocellular carcinoma resection
To explore the application effect of dexmedetomidine combined with ropivacaine for quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL) in open hepatocellular carcinoma resection.
Methods
2
A prospective study was conducted in 60 patients who underwent elective open hepatocellular carcinoma resection at Jining First People's Hospital.The patients were randomly divided into the compound group and the control group, with 30 cases in each group.Patients in the compound group received QLB-LSAL combined general anesthesia, and patients in the control group received simple general anesthesia. All patients underwent patient controlled intravenous analgesia (PCIA)postoperatively.The mean arterial pressure (MAP),heart rate (HR) and visual analogue scale (VAS) scores during rest and coughing at different time points were observed and compared between the two groups.The number of postoperative PCIA compressions, the dosage of sufentanil, the first postoperative exhaust time, the first postoperative ambulation time, the hospital stay and the occurrence of adverse reactions of the two groups were recorded.
Results
2
In the compound group,the HR and MAP were significantly lower than those o
f the control group at the time of skin incision (T2) and at the end of surgery (T3);the VAS scores during rest and coughing were significantly lower than those of the control group at the time of exiting the anesthesia recovery room and 6 hours and 12 hours after surgery; and the PCIA compression times were significantly less than those of the control group; the dosage of sufentanil was significantly lower than that in the control group 0 to 24 hours after surgery, and the dosage of sufentanil was higher than that in the control group 25 to 48 hours after surgery; the first postoperative ambulation time and the first postoperative exhaust time were significantly earlier than those in the control group; and the above differences were statistically significant(
P
<
0.05).There was no significant difference in the HR or MAP at 5 minutes into the operating room (T0) and 5 minutes before skin incision (T1), VAS scores during rest and coughing 24 hours and 48 hours after surgery, hospital stay and incidence of adverse reactions between the two groups (
P
>
0.05).
Conclusion
2
For patients with open hepatocellular carcinoma resection, dexmedetomidine combined with ropivazine for QLB-LSAL can provide more ideal postoperative analgesia, reduce perioperative opioid consumption, and have less impact on circulatory system, which is conducive to rapid postoperative recovery.
