Abstract: ObjectiveTo investigate the influence of vecuronium induced anesthesia for recurrent laryngeal nerve(RLN) evoked muscle potential in thyroid surgery.MethodsA total of 98 cases underwent thyroid surgery from March 2012 to March 2015 in our hospital were randomly divided into three groups: 30 cases in group A were performed anesthesia induction with 0.3 mg/kg vecuronium and no additional administration with muscle relaxant, 30 cases in group B were given vecuronium 0.3mg/kg for induction of anesthesia and appended muscle relaxant of vecuronium 0.3mg/kg for maintenance of anesthesia, 38 cases in group C were given vecuronium 0.6 mg/kg for anesthesia induction with additional muscle relaxant of vecuronium 0.3 mg/kg.ResultsThe SBP, DBP and HR at T2 (5 min after anesthesia induction), T3 (intubation), T4 (5 min after muscle relaxant administration) and T5 (at the end of surgery) were lower than those before anesthesia induction (T1) in all three groups （P＜0.05）. There was no statistical difference in SBP, DBP and HR among three groups comparison （P＞0.05）. No significant difference appeared in the muscle potential amplitude of RLN between before and after the dissection of thyroid in three groups (P>0.05). All cases were detected RLN muscle potential and accomplished the surgery successfully without serious complication. The rate of intraoperative limb movement was higher in group A than that in group B and C (P<0.05).ConclusionThe anesthesia induction with routine dosage vecuronium and muscle relaxant appending in general anesthesia can reduce the limb movement rate and has no effect on RLN muscle potential detection.
