Abstract: This study investigated the application value of peripheral hip nerve block (PENG) under ultrasound to assist spinal anesthesia in elderly total hip arthroplasty (THA). 180 patients over 60 years old were to undergo THA surgery under general anesthesia were selected as the research objects, and a randomized trial was conducted, of which 90 patients were selected as the research group (anesthesia method:PENG+spinal anesthesia), and the other 90 patients were selected as the control group (anesthesia method:spinal anesthesia). The operation time of spinal anesthesia, the onset time of anesthesia and the recovery time of spontaneous breathing of the patients in the research group were all lower than those in the control group (P<0.05). The mean artery pressure (MAP) value of the research group at the time of skin incision and 30 min after surgery was higher than that of the control group, the MAP value of the study group at 10 min after surgery was lower than that of the control group(P<0.05). The heart rate(HR) value of the study group was lower than that of the control group at 10 min after surgery, while at the time of skin incision the HR value was higher than that of the control group (P<0.05). The prothrombin time (PT) and activeated partial thromboplasting time (APTT) values of the study group were both higher than those of the control group 10 min after the operation, and the fibrinogen (FIB), substance P and cortisol (Cor) were lower than those of the control group (P<0.05). The overall satisfaction of anesthesia effect in study group was higher than that in control group, and the complication rate was lower than that in control group (P<0.05). Compared with the simple use of spinal anesthesia, the use of PENG-assisted spinal anesthesia under ultrasound in elderly THA patients has a more satisfactory anesthesia effect, and has less impact on the patient's hemodynamics, coagulation function and stress response.
