ObjectiveTo investigate the application value of lumbar plexus combined with sciatic nerve block anesthesia guided by ultrasound in the operation of intertrochanteric fracture of the elderly patients.
MethodsA total of 110 elderly patients with intertrochanteric fractures were randomly divided into the observation group and control group according to the random number table(55 cases in each group).The control group was treated with subarachnoid block anesthesia combined with epidural anesthesia, and the observation group was treated with lumbar plexus combined with sciatic nerve block anesthesia guided by ultrasound.The onset and maintenance time of nerve block, immunoglobulin levels before and after operation, pain degree and incidence rate of anaesthesia adverse reactions were compared between two groups.
ResultsThe onset time of sensory and motor nerves in observation group was shorter than that in control group(P＜0.01), and the maintenance time in observation group was longer than that in control group(P＜0.01).Before operation, the differences of the levels of IgG, IgM and IgE were not statistically significant(P＞0.05), and the levels of IgG, IgM and IgE in observation group at 6 h, 24 h and 72 h after operation were significantly higher than those in control group(P＜0.01).After 6, 12 and 24 hours of operation, the VAS scores in observation group were significantly lower than those in control group(P＜0.01), and the difference of the VAS score after 72 h of operation was not statistically significant(P＞0.05).The incidence rate of adverse reaction in observation group(14.55%) was lower than that in control group(34.55%)(P＜0.05).
ConclusionsThe application of lumbar plexus combined with sciatic nerve block anesthesia guided by ultrasound in the operation of intertrochanteric fracture of the elderly patients can shorten the onset time of anesthesia, enhance the immune function, reduce postoperative pain and incidence rate of adverse reactions, which is worthy of promotion.
