概括
移植前的肺功能测试 (PFTs) 可以预测肝移植的结果. 较低的强迫呼吸量 (FEV1) 与较差的生存率有关,而减少的扩散能力 (DLCO SB) 预测了移植后的呼吸死亡.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 肺部病理学 肺部病理学
- 移植手术 移植手术
背景情况:
- 肺功能测试 (PFT) 对于在肝移植 (LT) 之前评估呼吸能力至关重要.
- 移植前PFT和LT后结果之间的关联需要进一步调查.
研究的目的:
- 确定移植前的PFT参数是否预测LT后的整体存活率.
- 确定移植前PFTs和LT后呼吸道死亡原因之间的关系.
主要方法:
- 从2014年到2023年,对772个LT受益人的回顾性分析.
- 使用了考克斯回归和竞争风险回归模型.
- 对于年龄,性别和种族,PFT参数被规范化.
主要成果:
- 在1秒内强制呼气量较低 (FEV1) 与LT后生存率较差 (aHR 0.85) 独立相关.
- 移植时的年龄增加和目前的吸烟也预测了较差的生存率.
- 肺的低一次呼吸扩散能力 (DLCO SB) 独立预测LT后的呼吸死亡 (aSHR 0.66).
结论:
- 移植前的FEV1是LT后整体存活率的重要预测指标.
- 移植前的DLCO SB是LT后呼吸道死亡的重要预测因素.
- 在肝移植前的评估中,常规的PFT得到了支持.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
