Objective To compare the efficacy of ultrasound-guided iliopsoas plane block (IPB) and ultrasound-guided supra-inguinal fascia iliaca compartment block(S-FICB) in patients undergoing hip arthroplasty. Methods Fifty patients scheduled for elective unilateral hip arthroplasty, aged 18-95 years, 28 males and 22 females, BMI 17-35 kg/m2, ASA physical status Ⅰ-Ⅲ, were selected. Patients were divided into two groups using random number table method: IPB group (group I) and S-FICB group (group S), 25 patients in each group. In group I, 0.3% ropivacaine 10 ml was injected between the iliopsoas muscle and the iliofemoral ligament. In gourp S, 0.3% ropivacaine 40 ml was injected into the supra-inguinal fascia iliaca compartment. After surgery, patients were underwent patient-controlled intravenous analgesia with sufentanil. When VAS pain scores were more than 4, flurbiprofen axetil 50 mg was intravenously injected. The procedure time and onset time of nerve block were recorded. The dosage of propofol and remifentanil and the proportion of sufentanil injected during operation were recorded. VAS pain scores were recorded at rest and during exercise (hip lift at 15°) 2, 6, 8, 12, and 24 hours after operation. The number of effective and total PCIA, the dosage of sufentanil and the proportion of rflurbiprofen axetil injected 24 hours after operation were recorded. Postoperative nausea and vomiting, delirium, infection, local anesthetic poisoning, and quadriceps muscle weakness were recorded. Results Compaired with group S, the procedure time and onset time of nerve block in group I were significantly shortened, the proportion of sufentanil injected, VAS pain score during exercise 8 hours after operation, the incidence of quadriceps weakness was significantly decreased in group I (P < 0.05). There were no significant differences in VAS pain scores at rest and during exercise 2, 6, 12, and 24 hours after operation, the dosage of propofol and remifentanil during the operation, the numer of effective and total PCIA, the dosage of sufentanil, or the proportion of rflurbiprofen axetil injected 24 hours after operation between the two groups. There were no significant differences in nausea,delirium or infection between the two groups. Conclusion Ultrasound-guided iliopsoas plane block can provide adequate perioperative analgesia for patients undergoing hip arthroplasty without affecting hip motion ability, which is beneficial for early activity of the patients. |
