Abstract:Objective To analyze on the domestic and foreign literature on the incidences of cognitive impairment of general anesthesia or intraspinal anesthesia after lower extremity fractures by Meta analysis. Methods The related research reports published on Chinese Wanfang, PubMed, VIP, CNKI, Cochrane and EMbase databases from January 2013 to February 2018 on the incidences of cognitive impairment of general anesthesia or intraspinal anesthesia after lower extremity fractures were selected. Two staff members were screened in accordance with the documentation, exclusion criteria and technical roadmap. The quality of the literature was evaluated by the bias risk assessment tool in the Cochrane manual. Then RevMan 5.1 software was used to analyze the retrieved literature by Meta analysis. Results In this study, 10 domestic and foreign related reports were extracted, including 8 domestic documents and 2 foreign documents. In all of the literature, 925 patients were included, among which 415 cases were treated with general anesthesia, and 510 patients were treated with intraspinal anaesthesia. The results of heterogeneity test showed P = 0.42, I2 = 0. After fixed effect model analysis, it was found that the risk of postoperative cognitive dysfunction after general anesthesia for patients with lower limb fractures was significantly higher than that of patients with lower extremity fracture treated by spinal anesthesia (RR = 1.40, 95%CI: 1.04-1.88, P = 0.04). The results of the bias risk analysis was not found obvious bias. Conclusion The risk of cognitive impairment after general anesthesia in patients with lower extremity fractures is significantly higher than that in spinal canal anesthesia.
