ABSTRACT
Objective To investigate the risk factors of nausea and vomiting syndrome after thyroidectomy.Method The clinical data of 214 patients undergoing thyroidectomy were analyzed retrospectively to look into the risk factors.Results Seventy-two patients contracted nausea and vomiting syndrome after thyroidectomy,with an incidence of 33.64%.All of them had nausea of degrees 1,2 and 3,taking up 47.22%,27.78%and 25.00%,respectively.38.89%of them had vomiting of mild,intermediate and severe degrees, accounting for 32.14%,57.14% and 10.71%,respectively.Gender,smoking history,anesthesia and surgical duration were correlated with the syndrome(All P<0.05).Non-conditional Logistic regression analysis showed that female,general anesthesia, operative duration ≥2h were independent risk factors(all P<0.05).Conclusions Syndrome of nausea and vomiting after hyroidectomy has a higher incidence.Female,general anesthesia and surgical duration are independent risk factors.Interventional measures pertinent to these factors may reduce the incidence of nausea and vomiting syndrome after thyroidectomy.
