乳腺癌相关淋巴水肿测量工具尺的制作及应用

Production and application of measuring tool of breast cancer related lymphedema

目的：评价乳腺癌相关淋巴水肿测量尺（简称工具尺）在乳腺癌患者患肢测量中的应用效果。方法采用目的抽样选取术后康复治疗的乳腺癌患者10例；同时选取护士10名，随机分为观察组5名、对照组5名。两组同时对10例患者进行患肢周径测量，观察组应用工具尺，对照组应用普通软尺，共100个测量值。设定测量值介于本组平均值±1％区间者视为测量准确，比较两组测量值准确率差异。对患者进行患肢测量培训后，患者分为工具尺组5例和软尺组5例进行自我测量，比较患者自测准确率的差异。结果观察组护士测量准确率96％，对照组准确率66％，差异有统计学意义（χ2＝14.620，P〈0.01）。工具尺组患者中4例测量值准确，软尺组患者中只有1例准确。结论工具尺测量乳腺癌患者术后患肢淋巴水肿准确、便捷，值得在临床推广应用。

Objective To explore the effect of measuring ruler of breast cancer related lymphedema （ shortened as tool ruler） in affected limb measurement of breast cancer patients. Methods Ten breast cancer patients undergoing postoperative rehabilitation were selected by purposive sampling method. 10 nurses were selected and divided randomly into observation group and control group, each with 5 nurses. Cross-section diameters of the 10 patients′affected limbs were measured by nurses in the two groups at the same time, with the observation group using tool ruler and the control group using ordinary flexible measuring tape, with a total of 100 measured values. Measured values between ± 1% of average value within the group were determined as accurate. Accuracy rates of measured values in the two groups were compared. After training, patients were asked to measure themselves, with 5 patients using tool ruler and another 5 using flexible measuring tape. Accuracy rates of measured values of the two groups were compared. Results Accuracy rate of nurses in the observation group was 96%, while in the control group 66% （χ2=14.620, P〈0.01）. Among the 5 patients using tool ruler, 4 were with accurate measured values, while among those who used flexible measuring tape, only 1 got accurate measured value. Conclusions Using tool ruler to measure postoperative lymphedema of affected limbs in breast cancer patients is accurate and convenient, which makes it worth popularizing in clinical application.
