ObjectiveTo investigate the risk factors of perioperative anaesthesia management in postoperative headache induced by thyroidectomy. MethodsA 1:1 age and operation time matched case-control design study was performed. General anesthesia patients for elective thyroidectomy with postoperative headache (case group, VAS score >4) and without postoperative headache (control group, VAS score ≤4) were recruited. Univariate and multivariate analyses were performed to analyze the risk factors of postoperative headache after 24 and 48 hours of operation by using SPSS 18.0 software. ResultsA total of 134 patients were included; of which, 67 were in the case group and the other 67 were in the control group. The results of univariate analysis showed that female and administration of flurbiprofen axetil might be the risk factors of postoperative headache. The further multivariate analysis showed that administration of flurbiprofen axetil was significantly associated with decreased postoperative headache (OR=0.387, 95%CI 0.185 to 0.811). ConclusionPerioperative anesthesia management has a certain influence on postoperative headache induced by thyroidectomy. The use of flurbiprofen axetil during operation could reduce the incidence rate of postoperative headache.
