ObjectiveTo systematically evaluate the effect of Dexmedetomidine (Dex) on postoperative cognitive dysfunction (POCD) of Chinese patients undergoing abdominal surgeries. MethodsWe searched databases including PubMed, Web of Science, CNKI, CBM, VIP and WanFang Data from inception to April 2015, to collect randomized controlled trials (RCTs) about evaluating the effect of Dex on POCD of Chinese patients undergoing abdominal surgeries. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 8 RCTs were included. The results of meta-analysis showed that:compared with the control group, the MMSE scores of the Dex group were higher after surgeries in the first day (MD=1.46, 95%CI 0.98 to 1.95, P<0.000 01), the second day (MD=2.46, 95%CI 2.11 to 2.81, P<0.000 01), the third day (MD=1.81, 95%CI 0.37 to 3.25, P=0.01) and the seventh day (WMD=2.03, 95%CI 1.64 to 2.43, P<0.000 01). ConclusionCurrent evidence shows that the usage of Dex during abdominal surgeries can reduce the incidence of POCD in Chinese patients. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
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.
