Abstract

This mixed-method study evaluated the efficacy of lift assist device use (Binder®, Eagle®, Maxi Air®) relative to manual lifting/care-as-usual in reducing low back muscle activity and perceived exertion during simulated patient extrication tasks. User feedback was recorded to identify factors that might influence use. Twenty paramedics performed a floor to stretcher lift, lateral transfer, and confined space extrication care-as-usual and with lift assist devices. Use of a lift assist reduced low back muscle activity during floor to stretcher and confined space tasks by 34–47%. Paramedics perceived exertion decreased from ‘somewhat hard’ to ‘light’ or ‘very light’ when using an assistive device. Paramedics noted that ease of use, patient comfort, task time, patient acuity, among other considerations would influence use decisions. Lift assist devices were efficacious at reducing low back muscle activity and perceived exertion during floor to stretcher and patient extrication tasks.

采用混合方法描述在三种常见的病人解救情景中使用移位辅助装置减少腰背部肌肉骨骼疾病风险因素的效果。
这项混合方法研究评估了使用移位辅助装置(Binder®、Eagle®、Maxi Air®)相对于人工移位/照常护理在减少腰背肌肉活动和模拟病人解救任务中的体力消耗方面的效果。对用户反馈进行了记录,以确定可能影响使用的因素。20 名护理人员分别使用移位辅助设备和普通护理方式进行了从地面到担架的移位、横向转移和密闭空间脱困。使用移位辅助装置可将从地面到担架和密闭空间任务中的腰背肌肉活动减少 34-47%。在使用辅助设备时,护理人员认为体力消耗从 "有点吃力 "减少到 "轻微 "或 "非常轻微"。医护人员指出,易用性、患者舒适度、任务时间、患者敏锐度等因素都会影响使用决定。在从地面到担架和解救病人的任务中,移位辅助装置可有效减少腰背肌肉活动和感觉到的体力消耗。
