Title: Clinical Observation on Preemptive Analgesia with Intravenous Ketamine for Patients Undergoing Subtotal thyroidectomy
Abstract: 【Objective】 To observe the effects of preemptive analgesia with intravenous Ketamine on the postoperative pain for patients undergoing subtotal thyroidectomy.【Methods】 Forty cases scheduled for selective surgery of subtotal thyroidectomy were randomly divided into two groups.In Group K,Ketamine 1.0 mg/kg was given intravenously 3 minutes before skin incision and thereafter 0.5 mg/(kg·h) infusion continuously until skin closure.Normal saline was used instead of Ketamine in Group C.Postoperative pain was assessed by VAS(visual analogue scale)-score at 4,8,12,24 hours after operation,while adverse effects were assessed. 【Results】The VAS-score of Group K was significantly lower than that of group C(P0.05),but adverse effects such as nausea,vomit and swirl of two groups have no significant difference(P0.05).【Conclusion】 Preemptive analgesia with intravenous Ketamine provides satisfactory relief of postoperative pain with no obvious side effects for patients undergoing subtotal thyroidectomy.
