Effect of stellate ganglion block on postoperative sleep disturbance in patients undergoing nasal endoscopic surgery
Objective To explore the effect of stellate ganglion block(SGB)on postoperative sleep disturbance in the patients undergoing nasal endoscopic surgery.Methods Fifty-eight patients undergoing elective nasal endoscopic surgery under general anesthesia were divided into two groups with 29 cases each.Ultrasound-guided SGB was performed at 30 minutes before anesthesia induction in group A,which was not in group C as the control.The Pittsburgh Sleepiness Quotient Index(PSQI)scores on one day preoperatively,and on the 1st,3rd and 5th day postoperatively were compared between the two groups.The total sleep time,sleep efficiency and number of wakefulness were recorded on one day after surgery.VAS pain score was evaluated at 24 hours after operation.The SGB-related complications were observed and the cases needed remedial analgesia in 24 hours postoperatively were recorded.Results Compared with group C,group A had longer total nighttime sleep time with improved sleep efficiency and decreased number of wakefulness during nighttime sleep in one day postoperatively(P＜0.05).Compared with one day before operation,the PSQI scores of group C were increased on the 1st and 3rd day postoperatively,and the PSQI scores of group A were decreased on the 3rd and 5th day postoperatively(P＜0.05).The PSQI scores of group A were lower than those of group C on the 1st,3rd and 5th day postoperatively(P＜0.05).The VAS pain score of group A was lower than that of group C at 24 hours postoperatively(P＜0.05).There were no significant differences in the number of the cases needed remedial analgesia and the incidence rate of nausea and vomiting between the two groups(P＞0.05).Conclusion In the patients undergoing nasal endoscopic surgery,SGB can effectively improve postoperative sleep quality and reduce postoperative pain.
