- Abstract: Objective To observe the preventive effect of ultrasound-guided cervical vagus nerve block(CVB)in preventing oculocar-diac reflex.Methods A total of 86 patients who underwent posterior scleral reinforcement or ophthalmectomy were recruited and randomly divided into the general anesthesia group and the composite anesthesia group.After admission,patients in the two groups underwent conven-tional general anesthesia induction intubation,and the composite anesthesia group received another 1％lidocaine for right CVB under ultrasound guidance.The heart rate,blood pressure,saturation of peripheral oxygen,atropine usage and surgical procedures of the two groups were recorded.Postoperative comfort degree,hoarseness and complications related to nerve block were compared between the two groups.Results Compared with the general anesthesia group,the proportion of patients using atropine and the proportion of suspending operation in the composite anesthesia group were significantly reduced(P＜0.05),and the incidence of oculocardiac reflex and the level of oculocardiac reflex were significantly decreased(P＜0.05).The incidence of hoarseness in the composite anesthesia group was higher than that in the general anesthesia group,and the difference was statistically significant(P＜0.05).There was no complication related to nerve block occurred in the composite anesthesia group.Conclusion In ophthalmic surgery,ultrasound-guided right CVB can safely and effec-tively inhibit the occurrence of oculocardiac reflex.
