Abstract:
Objective:To evaluate the effects of different volumes of ropivacaine for iliopsoas muscle plane block on quadriceps strength in patients undergoing hip arthroplasty.Methods:In this prospective study, 75 patients of either sex, aged 40-80 yr, with a body mass index of 18.5-30.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, undergoing elective hip arthroplasty from June to December 2023 at Baoding First Central Hospital, were randomized into 3 groups ( n=25 each) by using a computer-generated randomization sequence: ropivacaine 5 ml group (group Ⅰ), ropivacaine 10 ml group (group Ⅱ), and ropivacaine 15 ml group (group Ⅲ). Before induction of anesthesia, iliopsoas muscle plane block was performed with 0.5% ropivacaine 5, 10 and 15 ml in Ⅰ, Ⅱ and Ⅲ groups, respectively. The lateral femoral cutaneous nerve block was carried out using 0.5% ropivacaine 5 ml in all the three groups. The quadriceps muscle strength and status of quadriceps motor block in the affected limb were assessed on admission to postanesthesia care unit (PACU) and at 2, 4, 6, 24 and 48 h after surgery. The consumption of dezocine, score for patient′s satisfaction with analgesia, and occurrence of complications were recorded. Results:Compared with group Ⅰ, the quadriceps muscle strength scores were significantly decreased on admission to PACU and at 2, 4 and 6 h postoperatively in group Ⅲ, the rate of quadriceps motor block was significantly increased on admission to PACU in group Ⅱ, and the rate of quadriceps motor block was significantly increased on admission to PACU and at 2 and 4 h postoperatively in group Ⅲ ( P<0.05), and the consumption of dezocine was significantly decreased in group Ⅱ and group Ⅲ ( P<0.05). Conclusions:The recommended volume of ropivacaine for iliopsoas plane block is 10 ml in patients undergoing hip arthroplasty.
