Analysis of Clinical Effect of Subanesthetic Dose of Esketamine Combined With Hip Capsule Peripheral Nerve Block in Elderly Patients Undergoing Total Hip Arthroplasty

Abstract

To observe the clinical effect of esketamine combined with hip capsule peripheral nerve block in elderly patients undergoing total hip arthroplasty. A total of 120 elderly patients who underwent total hip arthroplasty in our hospital from January 2020 to May 2021 were randomly divided into three groups, 40 cases in each group. The observation group A was treated with esketamine subanesthetic dose combined with hip capsule peripheral nerve block, the control group B was treated with esketamine subanesthetic dose combined with lumbar plexus block, and the control group C was treated with esketamine subanesthetic dose for general anesthesia. The onset time of anesthesia, duration of block, postoperative recovery time, postoperative extubation time, MAP and HR indexes before anesthesia (T0), during skin incision (T1), 30 minutes after the start of surgery (T2), and at the end of surgery (T3) were recorded in the three groups, and the VAS score and Ramsay score at 0.5 h, 2 h, 6 h, 12 h, and 24 h after surgery, as well as the incidence of postoperative adverse reactions were recorded in the three groups.
