Title: Clinical application of the femoral nerve combined with popliteal fissure sciatic nerve block in elderly patients with below knee surgery
Abstract: Objective
To investigate the clinical application of ultrasound-guided femoral nerve combined with popliteal fissure sciatic nerve block in elderly patients with below knee surgery.
Methods
A total of 94 cases of elderly patients undergoing surgery under knee joint were randomly divided into observation group and control group, with 47 cases in each group. The patients in the observation group underwent ultrasonography-guided femoral nerve combined with popliteal fossa sciatic nerve block, and the patients in the control group received lumbar and spinal combined anesthesia. The mean arterial pressure, heart rate, anesthesia effect and adverse reaction were observed before and after anesthesia at 15, 30 and 60 min after anesthesia, the time of anesthesia operation, the time of sensory nerve block, the time of motor nerve block were compared between the two groups.
Results
The time of anesthesia operation and sensory nerve block (T1, T3) in the observation group were significantly longer than those in the control group, and the sensory nerve block (T2) and motor nerve block (T1, T2, T3) were significantly shorter than those in the control group, and the differences were statistically significant (P 0.05). The MAP in the control group was significantly lower than that in the observation group at 15, 30 and 60 min after anesthesia, and the difference was statistically significant (P 0.05). The excellent and good rate of anesthesia in the observation group and the control group were 100% and 95.74% respectively. There was no significant difference (P>0.05). The incidence of adverse reactions in the observation group(4.26%)was significantly lower than that in the control group(21.28%), and the difference was statistically significant (P<0.05).
Conclusions
Ultrasound-guided femoral nerve combined with popliteal fissure sciatic nerve block in the elderly below knee surgery has good anesthesia effect. The operation is convenient, the patient’s vital signs are stable and the adverse reaction is small, and it is worthy to be widely popularized in the clinic.
