目的以周径测量结果为标准,比较多频生物电阻抗分析仪与接触式水分测量仪检测继发性上肢淋巴水肿的准确性。方法随机选取在我科进行淋巴手法引流治疗乳腺癌根治术后继发性上肢淋巴水肿患者18名,以周径测量获得的上肢增粗程度为标准,将多频生物电阻抗分析仪和接触式水分测量仪对组织水肿的检测结果,与周径改变进行相关性分析。结果患肢周径变化和两种水分测量的结果均显示患者治疗后水肿程度减轻。相比接触式水分测量仪的结果(r=0.490,P<0.05),多频生物电阻抗分析仪的测试结果(r=0.579,P<0.05)与周径测量结果相关性系数更高。结论两种水分检测方法均可用于诊断上肢淋巴水肿,而多频生物电阻抗分析仪对组织水肿测量的准确性较高。

Objective To compare the accuracy of multi -frequency bioelectrical impedance analysis and the MoistureMeterD Compact to detect tissue edema in secondary lymphedema of upper limb. Methods Eighteen patients with secondary lymphedema after radical mastectomy, treated by manual lymph drainage, were randomly selected in this study. The measurement of circumference of upper limb was determined as standard, which had an correlation analysis with multi-frequency bioelectrical impedance analysis and MoistureMeterD Compact ’s results on tissue edema change. Results Accoring to the circumference change and the measured results of multi-frequency bioelectrical impedance analysis and the MoistureMeterD Compact, the degree of lymphedema was decreased after treatment. The multifrequency bioelectrical impedance’s test results had an relatively higher correlation (r=0.579, P<0.05) with the results of the standard, comparing to the results of the MoistureMeterD Compact (r=0.490, P<0.05). Conclusion Both multi-frequency bioelectrical impedance analysis and the MoistureMeterD Compact could be used for the measurement of lymphedema of upper limb, and multifrequency bioelectrical impedance analysis have an higher accuracy in the measurement of tissue edema.
