目的 探讨头位角度预警器在视网膜脱离术后强迫体位患者中的应用效果，为提高患者体位准确率提供保障。 方法 便利抽样法选取某医院眼科行单眼视网膜复位术的患者260例（260眼）为研究对象，按入院先后将2021年3-7月收治的130例患者和对应眼科护士28名作为对照组，采用常规的体位支持与目测监测法；2021年8-12月收治的130例患者和对应护士28名作为观察组，采用头位角度预警器的体位支持与基于电子报警装置的监测法。评价并比较两组患者术后体位准确率和护士任务负荷程度。 结果 观察组患者使用头位角度预警器后，术后连续48 h的强迫体位执行准确率高于对照组，差异有统计学意义（χ²=1039.680，P＜0.001）。观察组护士任务负荷指数得分为（73.36±7.05）分，低于对照组[（86.07±5.50）分]，差异亦有统计学意义（t=7.528，P＜0.001）。 结论 头位角度预警器替代传统的人工监测方式，发挥电子化监测方式的精确优势，有效解决体位护理难点，值得临床推广应用。

Objective To explore the effect of head position angle warning device in patients with forced posture after retinal detachment surgery and to improve the accuracy of patients’ postures. Methods By convenience sampling method,a total of 260 patients (260 eyes) who underwent retinal reattachment surgery in the Department of Ophthalmology of a tertiary A hospital were selected.130 patients and 28 corresponding ophthalmic nurses who were admitted from March to July 2021 were selected as the control group,using the routine position support nursing methods and visual monitoring methods.From August to December 2021,130 patients and 28 corresponding nurses were selected as the observation group,using the posture support method of head position angle early warning device and the monitoring method based on intelligent alarm device.The accuracy of postoperative posture and the degree of nurses’ task load were evaluated and compared between the two groups. Results After the use of the head Angle warning device,the accuracy of forced position execution for 48 consecutive hours after surgery in the observation group was higher than that in the control group,and the difference was statistically significant （χ²=1039.680，P＜0.001）.The task load index score of the observation group was (73.36±7.05),which was lower than that of the control group [(86.07±5.50)],and the difference was statistically significant (t=7.528,P＜0.001). Conclusions The head position angle warning device replaces the traditional manual monitoring method,gives play to the accurate advantages of electronic monitoring method,and effectively solves the difficulties in position nursing.It is worthy of clinical application.
