用体描箱监测甲减病人心排血量和呼吸肌力

目的：了解体描箱法对甲减时心肺功能监测的意义。方法：用体描箱对21例甲减病人甲状腺素药物治疗前后心排血量及呼吸肌力进行监测。结果：甲减病人Qc、CI、SV、SI减低，FVC、FEV1降低，同时发现随治疗延缓Qc、CI、SV、SI、FVC恢复。结论：甲减患者存在心排血量减少和呼吸肌力的减退，而且这此损害经治疗可逆转。无创简便的体描箱法为观察甲减病人心肺功能提供了新的方法。

Measuring Heart Output and Respiratory Muscular Force in Patients with Hypothyroidism with Body Plethysmography

Objective: To study the clinical significance of the function of heart and lung in patients with hypothyroidism with ple-thysmograph. Methods: The heart output and respiratory muscular force were measured by body plethysmography in 21 pa-tients before and after thyroidization. Results: The Qc, CI, SV, SI, FVC and FEV1 in the patients were significantly lower than those in control. Meanwhile, the decreased Qc, CI, SV, SI and FVC in the patients significantly restored along with the treatment of thyroidization. Conclusion: The heart output and respiratory muscular force were low in patients with hypothyroidism. But these changes could be conversed with thyroidization. The simple and non-invasive body plethys-mograph provides a new method to observe heart and lung function in patients with hypothyroidism.
