Poor working postures in morning care operations contribute significantly to work-related muscle fatigue and low back pain among ICU (Intensive Care Unit, ICU) nurses. However,there are few field studies on the relationship between Poor working postures and work-related muscle fatigue, low back pain among ICU nurses.
This study aims to assess the frequency and degree of posture hazards associated with poor working postures during morning care operations of ICU nurses.
Two ICUs in a Grade-A tertiary hospital in Hunan Province were randomly selected for the field study in May-June 2021 research. The image data of the participating nurses' morning care work postures were collected by observation method and image recording method, and the postural hazard level was assessed by the two-person interpretation method of the work posture analysis system. The mean and standard deviation, frequency and percentage were used for the basic statistical description, and the general linear model multivariate Hotelling's T test was used to calculate the Hotelling's T and F statistics to explore the pattern of change in the postural hazard score curves.
A total of 45 nurses were observed during morning care operations, resulting in 47.8 h of video data and 34,428 effective static operation posture pictures. Among these pictures, 21,166 (61.5%) depicted poor working postures. Nurses spent up to 7 min and 30 s maintaining a challenging posture during oral care, with the highest postural hazard score (M = 2.2, SD = 0.3) observed during defecation care. Each patient requires a total of 25-30 min of oral care per day.The Hotelling's T test indicated that the change curve of the postural hazard score in each step revealed the largest second-order F value, F = 52.931, P < 0.001.
ICU nurses frequently adopt poor working postures during morning care operations. Further research should focus on optimizing safe working postures to prevent or minimise detrimental occupational hazards resulting from poor working postures.Research on occupational low back pain among ICU nurses can help them work more efficiently, and thereby improving their nursing level.
重症监护病房（ICU）护士在晨护操作中不良的工作姿势是导致其工作相关肌肉疲劳和腰痛的重要原因。然而，关于ICU护士不良工作姿势与工作相关肌肉疲劳、腰痛之间关系的现场研究较少。
本研究旨在评估ICU护士晨护操作中与不良工作姿势相关的姿势危害的频率和程度。
2021年5月至6月，在湖南省一家三级甲等医院随机选取两个ICU进行现场研究。采用观察法和图像记录法收集参与研究护士晨护工作姿势的图像数据，运用工作姿势分析系统的双人解读法评估姿势危害水平。采用均值、标准差、频率和百分比进行基本统计描述，运用一般线性模型多元Hotelling's T检验计算Hotelling's T和F统计量，以探索姿势危害得分曲线的变化模式。
晨护操作期间共观察了45名护士，获得47.8小时的视频数据和34428张有效的静态操作姿势图片。其中，21166张（61.5%）呈现出不良工作姿势。护士在口腔护理时保持挑战性姿势的时间长达7分30秒，排便护理时观察到的姿势危害得分最高（M = 2.2，SD = 0.3）。每位患者每天的口腔护理总时长为25 - 30分钟。Hotelling's T检验表明，各步骤中姿势危害得分的变化曲线显示出最大的二阶F值，F = 52.931，P < 0.001。
ICU护士在晨护操作中经常采用不良工作姿势。进一步的研究应聚焦于优化安全工作姿势，以预防或最小化不良工作姿势导致的有害职业危害。对ICU护士职业性腰痛的研究有助于他们更高效地工作，从而提高护理水平。
