Abstract 【Objective】 To investigate the effect of lumbar plexus sciatic nerve block combined with low-dose propofol anesthesia on hemodynamics, postoperative cognitive function and complications in elderly patients with intertrochanteric fracture.【Methods】 Sixty patients with intertrochanteric fracture in our hospital from September 2017 to September 2019 were selected and randomly divided into observation group and control group (30 cases in each group). The control group was operated under general anesthesia, and the observation group was treated with lumbar plexus sciatic nerve block combined with low-dose propofol anesthesia. The hemodynamic indexes [heart rate (HR) and mean arterial pressure (MAP)], postoperative cognitive function [Montreal Cognitive Assessment Scale (MoCA), Mini Mental State Examination (MMSE) score], anesthetic effect and complications of the two groups were compared.【Results】 The MAP and HR index levels of the two groups at T1 were significantly lower than those at T0, but the map level of the control group at T1 was significantly lower than that of the observation group, and the difference was statistically significant (P>0.05); The excellent and good rate of anesthesia effect in the observation group was significantly higher than that in the control group (86.67% vs 60.00%), and the differences were statistically significant (P<0.05). The MoCA and MMSE scores of the two groups at 1 day and 3 days after operation were lower than those before operation, but the MoCA and MMSE scores of the observation group were significantly higher than those of the control group. The incidence of complications in the observation group was significantly lower than that in the control group (16.67% vs 40.33%), and the differences were statistically significant (P<0.05).【Conclusion】 Lumbar plexus sciatic nerve block combined with low-dose propofol anesthesia for elderly patients with intertrochanteric fracture has the advantages of stable hemodynamics and significant anesthetic effect, which can effectively reduce the occurrence of postoperative cognitive dysfunction and postoperative complications.
