Abstract Objective: To analyze the effects of lumbar plexus block combined with general anesthesia on vital signs and postoperative analgesia satisfaction in elderly patients undergoing hip replacement. Methods: 80 elderly patients undergoing hip replacement in the hospital from August 2017 to August 2019 were enrolled in the study. They were divided into observation group and control group by random number table method and simple random grouping method, 40 cases in each group. The control group was given simple general anesthesia, while observation group was given lumbar plexus block combined with low general anesthesia. The surgery and anesthesia related indexes were recorded. The vital signs [mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO2)], postoperative pain [visual analogue scale (VAS)], analgesia satisfaction and adverse reactions were compared between the two groups at tracheal intubation time (T0), at 1 min before surgical skin incision (T1), at incision suture (T2) and at 30 min after entering anesthesia recovery room (T3). Results: The sufentanil dosage in observation group was less than that in control group (P<0.05), and postoperative extubation time was significantly shorter than that in control group (P<0.05). There was no significant difference in operation time or hospitalization time between the two groups (P>0.05). MAP and HR at T1to T3 were increased compared with those at T0 in both groups, while SpO2 was lower than that at T0. MAP and HR at T1, T2 and T3 in observation group were lower than those in control group, while SpO2 was higher than that in control group (P<0.05). VAS scores of observation group were lower than those of control group at 2h, 12h, 24h and 48h after surgery (P<0.05). The postoperative analgesia satisfaction of observation group was significantly higher than that of control group (P<0.05). The incidence of adverse reactions in observation group within 48h after surgery was lower than that in control group (P<0.05). Conclusion: Lumbar plexus block combined with general anesthesia can effectively reduce the dosage of sufentanil, shorten the extubation time, reduce the fluctuation of vital signs and postoperative adverse reactions in elderly patients with hip replacement, and the analgesic effect is satisfactory, which is worthy of clinical popularization and practice.
