ABSTRACT
Objective@#To investigate the effect of peripheral nerve block combined with venous fast track anesthesia on elderly patients undergoing lower extremity orthopedic surgery.@*Methods@#From September 2015 to December 2017, 64 senile patients with lower extremity orthopedic surgery in the Fifth Hospital of Ningbo were selected in the research.According to the different methods of anesthesia, the patients were divided into observation group (30 cases, application of combined intravenous peripheral nerve block and fast track anaesthesia), and the control group (34 cases, application of simple intravenous general anesthesia). The heart rate, average arterial pressure, spontaneous breathing recovery time, extubation time, complication rate and cognitive function scores of the two groups were compared.@*Results@#The heart rate and average arterial pressure of T1 and T3 in the observation group were significantly lower than those in the control group (P<0.05). The spontaneous breathing recovery time[(8.32±3.26)min] and extubation time[(9.69±4.29)min] in the observation group were significantly shorter than those in the control group[(18.24±5.23)min and (27.24±4.58)min](t=8.961, 15.756, all P<0.05). The incidence rate of postoperative complications in the observation group (3.33%) was significantly lower than that in the control group (20.59%)(χ2=4.338, P<0.05). The cognitive function score of the observation group was significantly higher at 4 h and 8 h after surgery than that of the control group (t=6.745, 8.494, all P<0.05).@*Conclusion@#Peripheral nerve block combined with intravenous fast-track anesthesia is very feasible for elderly patients undergoing lower limb orthopedic surgery.The time for patients to recover from spontaneous breathing and extubation is shorter, and the risk of complications such as delirium, restlessness, nausea and vomiting is lower.
