Abstract

Abstract: Objective To investigate the effect of dexmedetomidine combined with ropivacaine femoral nerve block on postoperative analgesia after total hip replacement （THR）. Methods A total of 160 patients with THR admitted from September 2018 to September 2020 were selected as study subjects. The patients were divided into a control group （odd number, 80 cases） and an observation group （even number, 80 cases） by digital odd-even method. Both groups received continuous femoral nerve block for analgesia after surgery, with a background dose of 8 mL/h and a shock dose of 4 mL per 30 min. The control group was prescribed 0.2% ropivacaine and the observation group was prescribed 1 μg/mL dexmedetomidine combined with 0.1% ropivacaine. The morphine consumption, Visual Analogue Scale （VAS） score at postoperative 6 h, 12 h, and 24 h, Pittsburgh Sleep Quality Index （PSQI） at postoperative 1 d and 7 d, and adverse reactions were compared between the two groups. Results The morphine consumption, the VAS scores 6 h and 12 h after operation, the PSQIs 1 d and 7 d after operation, and the incidence of complications of the observation group were significantly lower than those of the control group （P<0.05）. Conclusion Dexmedetomidine combined with ropivacaine femoral nerve block has a significant analgesic effect after THR operation, and it can reduce morphine dosage and postoperative pain, improve sleep quality, and reduce postoperative complications.
