Abstract:
Objective To observe the influence of dexmedetomidine applied in combined acupuncture-medication anesthesia on vomiting after thyroidectomy. Method Seventy patients who were going to receive thyroidectomy were randomized into group A and B, with 35 cases in each group. Combined acupuncture-medication anesthesia [electroacupuncture at Hegu (LI4), Neiguan (PC6) and Futu (ST32) plus intravenous infusions of sufentanil citrate injection (0.3 mg/kg) 20 minutes before operation]was adopted in both groups. Group A was additionally intervened by constantvelocity micropump infusion of dexmedetomidine hydrochloride injection (0.5 mg/kg) within 10 minutes before operation and remaining 0.4 mg/kg/min during operation, while group B was intervened by infusion of normal saline 10 minutes before operation. The observer's assessment of awareness/sedation (OAA/S) scores at different time points[lying in bed for 5 minutes before operation (T0), before the beginning of the operation (T1), 30 minutes after operation (T2), 60 minutes after operation (T3) and at the end of operation (T4)] in the two groups were observed. The additional times and total dose of sufentanil during operation, the number of cases using esmolol and urapidil, and the number of vomiting cases occurred within 2 hours after operation and 2～24 hours after operation in the two groups were recorded.Result The additional times and total dose of sufentanil during operation in group A were significantly different from those in group B (P<0.01). The utilization rate of esmolol and urapidil were respectively 31.4％ and 14.3％ in group A versus 77.1％ and 65.7％ in group B, and the between-group differences were statistically significant (P<0.01). The incidence of vomiting within 2 hours after operation and 2～24 hours after operation were respectively 20.0％ and 17.1％in group A versus 54.3％ and 42.9％ in group B, and the between-group differences were statistically significant (P<0.01). The OAA/S scores at different time points (T1, T2, T3 and T4) in group A were significantly different from those in group B (P<0.01). Conclusion Dexmedetomidine applied in combined acupuncture-medication anesthesia can reduce the additional times and total dose of sufentanil during thyroidectomy, and it can reduce the incidence of postoperative vomiting as well.
