Effect of ultrasound-guided stellate ganglion block on intraoperative fentanyl dosage in patients undergoing open thyroidectomy
Objective To investigate the effect of ultrasound-guided stellate ganglion block(SGB)on intraoperative fentanyl dosage in the patients undergoing open thyroidectomy.Methods A total of 70 patients with elective open thyroidectomy under general anesthesia in the Affiliated Hospital of North Sichuan Medical College from November 2021 to April 2022 were selected as the study subjects and divided into the SGB group(group S,n=35)and the control group(group C,n=33).The group S conducted ultrasound-guided SGB at 15 min before anesthetic induction(injection of 0.25%marcaine 6-8 mL),and group C conducted the stellate ganglion recognition under the ultrasound guidance in 15 min before anesthetic induction without conducting other operations.All patients all received the anesthesia induction and maintenance under the same BIS moni-toring.The fentanyl dosage,recovery time,anesthetic drugs dosage,fluid infusion amounts,bleeding volume,use rate of atropine and ephedrine,operation time and postoperative complications as well as the VAS scores in PACU 30 min,at postoperative 3,6,12,24 h were recorded.Results Compared with group C,the intraopera-tive amount of fentanyl in group S was significantly decreased[(247.9±65.4)μg vs.(295.7±61.5)μg,P=0.003].The propofol dosage,cisatracurium dosage,fluid infusion amounts,bleeding amounts,use rate of atro-pine and ephedrine,recovery time and incidence rate of complications had no statistical differences between the two groups(P>0.05).The VAS scores at various time points in group S all were lower than those in group C(P<0.05).Conclusion Ultrasound-guided SGB could reduce the fentanyl use amounts during operation in the patients with open thyroidectomy.
