OBJECTIVE: To evaluate the effects of general anesthesia and spinal anesthesia on postoperative mental status and early cognitive function in elderly patients undergoing orthopaedic surgery. METHODS: 100 elderly patients undergoing orthopaedic surgery were enrolled in our hospital from May 2017 to May 2019. They were divided into control group (general anesthesia, n=50) and observation group (vertebral according to random number table method). The clinical effects of intravascular anesthesia, n=50) were compared. The mental status of patients before and after 1h, 3h, 6h, 24h, 48h was evaluated by mental state evaluation scale (MMSE). The MMSE scores were used to identify the two groups of patients at 1h, 3h and 6h after operation. The situation of the obstacle is assessed. RESULTS: There was no significant difference in hemodynamics between the two groups before and after anesthesia (P>0.05). Compared with the control group, the operation time, awake time and language presentation time of the observation group were significantly shorter (P<0.05). There was no significant difference in MMSE score between the two groups before operation (P>0.05). The MMSE scores of the observation group were significantly higher than those of the control group (P<0.05). The incidence of cognitive impairment and mental confusion in the observation group was significantly lower than that in the control group (P<0.05). ). Conclusion: Intra-arterial anesthesia for elderly orthopedic surgery can prevent and reduce the occurrence of postoperative cognitive dysfunction, mental disorder and other complications, and it is not easy to affect the mental state of patients. The clinical application value is far-reaching.
