Advanced haemodynamic monitoring via transpulmonary thermodilution (TPTD) devices has gained popularity in recent years. The intrathoracic blood volume index (ITBVI) and the global end-diastolic blood volume index (GEDVI) calculated by single indicator TPTD devices have been shown to reliably estimate cardiac preload. The normal range of values for ITBVI is provided by the manufacturers. Evidence is now emerging that certain clinical scenarios can lead to increased ITBVI values. We report two cases of persistently high ITBVI in patients with hepatic cirrhosis complicated by hepatopulmonary syndrome.
近年来，通过经肺热稀释（TPTD）设备进行的高级血流动力学监测越来越受欢迎。单指标TPTD设备计算得出的胸腔内血容量指数（ITBVI）和全心舒张末期血容量指数（GEDVI）已被证明能够可靠地估计心脏前负荷。制造商提供了ITBVI的正常取值范围。目前有证据表明，某些临床情况可导致ITBVI值升高。我们报告了两例肝硬化合并肝肺综合征患者ITBVI持续升高的病例。
