恒温冲洗液在单侧双通道脊柱内镜术中的应用疗效OA

Objective:To explore the effect of 37℃ constant-temperature irrigation fluid on core body temperature and lo-cal inflammatory mediators in patients undergoing unilateral biportal endoscopic surgery(UBE).Methods:Sixty patients who underwent UBE surgery from June 2024 to August 2025 were randomly divided into control group and observation group.Both groups were operated on by the same experienced chief physician.The observation group was irrigated with normal saline maintained at 37℃,while the control group was irrigated with normal saline at room temperature(25℃).The efficacy was evaluated by monitoring the intraoperative core body temperature,VAS scores at 12 h,l week,and 3 weeks postoperatively,and the levels of inflammatory factors TNF-α and IL-6 in the drainage fluid.Results:At 60 min of the operation,the core body temperature of the patients in the control group significantly decreased to(35.5±0.3)℃,with a hypothermia incidence rate of 86.67％(26/30);the body temperature of the observation group was(36.2±0.4)℃,and the hypothermia incidence rate was 36.67％(11/30).The differences between the two groups were statisti-cally significant(P＜0.05).One week and three weeks after the operation,the VAS scores of the observation group were significantly lower than those of the control group(P＜0.05).There was no statistical difference in VAS scores between the two groups 12 h after the operation(P＞0.05).At 3 h and 6 h after the operation,the levels of TNF-α and IL-6 in the drainage fluid of the observation group were significantly lower than those of the control group(P＜0.05).Conclus-ion:The use of 37℃ constant temperature irrigation fluid during UBE can effectively maintain the stability of core body temperature during the perioperative period,reduce the incidence of hypothermia,and alleviate local inflammatory responses,which is helpful to relieve postoperative pain.
