Clinical Observation Of Two Different Positions On The Impact Of Postoperative Nausea And Vomiting After Thyroidectomy

Subject: Comparison of two different positions for preventing postoperative nausea andvomiting after thyroid surgery.Objective: To observe the effects of different positions on preventing postoperative nauseaand vomiting in adult undergoing thyroid surgery.Methods:400ASA I or II female patients undergoing thyroid surgery under generalanesthesia were randomly experiment.18to65years old. We excluded the patients sufferingfrom nervous system disease, severe liver and kidney dysfunction, using anti-nausea drugsand sugar cortical hormone drugs within a week, all patients don’t use self-control analgesia.All patients were randomly divided into2groups(n=200each): Control group (Group C) andExperimental group (Group E)．In Experimental group (Group E)，all patients always low halflying position (head and shoulders up30°) after operation, Control group(Group C) accepttraditional body position nursing care after operation. All patients were given the sameintravenous general anesthesia. All patients were awake after operation and extubated. ThePONV, nausea, vomiting and headache after2h,6h,12h,24h. using the anti-nausea drugs, thedays of hospitalization between the two group were observed and recorded.Results：Nausea and vomiting are mainly occurred an the6-12h after the operation. Group Eincluding a history of motion sickness and PONV has lower incidence of postoperativenausea and vomiting and headache discomfort than Group C (P<0.05). The doses and times ofanti-nausea drugs, and the average hospitalization time is lower than Group C (P<0.05).Conclusion：Half supine position can reduce the incidence of PONV, reduce anti-nausea drugapplication, length of hospital stay and the hospital costs.
