Antiarrhythmic and analgesic efficacy of stellate ganglion block in laparoscopic cholecystectomy

ABSTRACT

Background

To explore the effect of right stellate ganglion block (RSGB) during laparoscopic cholecystectomy (LC) for control of intraoperative arrhythmia during CO₂ pneumoperitoneum and postoperative pain relief

Methods

Forty patients undergoing LC in our hospital were selected as the subjects and were randomly divided into group S (20 cases) and group C (20 cases), all patients received RSGB, 10 mL of lidocaine 2% under ultrasound guidance to compare the incidence of arrhythmia (1ry outcome), changes of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MBP) in different time points and postoperative visual analogue scale (VAS) was reported in the 1st, 6th, and 12th hours, respectively, with time to first analgesia request.

Results

Intraoperative arrhythmias was significantly lower in group S rather than group C (P = 0.037); postoperative pain profile revealed that there was a significant difference between the 2 groups presented as longer duration for first time to request analgesia (P = 0.015) and lower VAS scores specially at the 1^st and 6^th postoperative hours in group S compared to group C (P < 0.001 and 0.004); changes in heart rate and blood pressure, there was a significant difference between the 2 groups in values of both parameters 5 minutes following CO₂ insufflation, group S showed significantly lower HR, SBP, and MBP at this time point than group C.

Conclusion

Patients received RSGB before laparoscopic cholecystectomy can experience lower incidence of arrhythmia, better intraoperative hemodynamics, and effective pain control postoperatively.
