Effects of ultrasound-guided erector spinae plane block on analgesic dosage, lumbar function and pain in patients undergoing percutaneous kyphoplasty / 中国基层医药

ABSTRACT

Objective:To investigate the effects of ultrasound-guided erector spinae plane block on analgesic dosage, lumbar function and pain in patients undergoing percutaneous kyphoplasty.Methods:A total of 100 patients who underwent percutaneous kyphoplasty in Hangzhou Cancer Hospital from November 2018 to October 2021 were included in this study. They were randomly assigned to undergo either local infiltration anesthesia (control group, n = 50) or ultrasound-guided erector spinae plane block (observation group, n = 50). Analgesic dosages, pain status at different phases (Visual Analogue Scale score) and lumbar function (Oswestry Disability Index score), intraoperative and postoperative conditions (operative time, time to get out of bed, time to first exhaust), and the incidence of adverse reactions were compared between the two groups. Results:At 24 and 48 hours after surgery, the amount of analgesics infused in the observation group was (24.54 ± 2.52) mL and (55.68 ± 5.61) mL, respectively, and the number of analgesic pump pressings was (1.01 ± 0.26) times and (3.15 ± 1.02) times, which were significantly lower than those in the control group [amount of analgesics infused at 24 and 48 hours after surgery (32.78 ± 3.31) mL, (62.57 ± 6.42) mL; the number of analgesic pump pressings at 24 and 48 hours after surgery (6.42 ± 1.53) times, (10.78 ± 2.45) times, t = 14.00, 5.71, 24.65, 20.33, all P < 0.001]. Visual Analogue Scale score at the time at which the balloon was pressurized and expanded in the observation group was significantly lower than that in the control group [(4.10 ± 0.87) points vs. (4.65 ± 1.01) points, t = 2.92, P < 0.05]. At 1 day and 1 month after surgery, Oswestry Disability Index score in the observation group was (18.37 ± 2.78) points and (12.15 ± 2.02) points, respectively, which were lower than (23.56 ± 3.42) points and (17.53 ± 2.34) points in the control group ( t = 8.33, 12.31, both P < 0.05). The time to get out of bed and the time to first exhaust in the observation group were (9.12 ± 2.54) days and (23.56 ± 4.56) hours, respectively, which were significantly shorter than those in the control group [(11.64 ± 3.12) days, (28.14 ± 5.12) hours, t = 4.43, 4.72, both P < 0.001). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Ultrasound-guided erector spinae plane block for percutaneous kyphoplasty can effectively ameliorate lumbar spine function, reduce postoperative pain, and facilitate postoperative recovery, without affecting the dosage of narcotics and analgesics. The method is safe and effective.
