To study the hemodynamics in the immediate post transplant period and compare patients with alcoholic vs viral cirrhosis.
Between 2000-2003, 38 patients were transplanted for alcoholic cirrhosis and 28 for postviral cirrhosis. Heart rate (HR), central venous pressure (CVP), mean arterial pressure (MAP), pulmonary capillary wedge pressure (PCWP), cardiac index (CI), systemic vascular resistance index (SVRI), pulmonary artery pressure (PAP), and pulmonary vascular resistance index (PVRI) were measured immediately and 24 h post transplantation.
Hyperdynamic circulation persisted at 24 h following transplantation with an elevated CI of 5.4 +/- 1.3 L/(min x m(2)) and 4.9 +/- 1.0 L/(min x m(2)) in the viral and alcoholic groups, respectively, and was associated with a decreased SVRI. Within the first 24 h, there was a significant decrease in HR and increase in MAP; the extent of the change was similar in both groups. The CVP, PCWP, and SVRI increased, and CI decreased in the viral patients, but not the alcoholic patients. Alcoholics showed a lower PVRI (119 +/- 52 dynes/(cm(5) x m(2)) vs 166 +/- 110 dynes/(cm(5) x m(2)), P < 0.05) and PAP (20 +/- 7 mmHg vs 24 +/- 7 mmHg, P < 0.05) compared to the viral group at 24 h.
Hyperdynamic circulation persists in the immediate post-transplant period with a faster improvement in the viral group. Alcoholic patients have a more pronounced pulmonary vasodilatation.
研究移植后即刻的血液动力学变化,并比较酒精性和病毒性肝硬化患者的差异。
2000 年至 2003 年间,38 例酒精性肝硬化患者和 28 例病毒性肝硬化患者接受了肝移植。分别在移植后即刻和 24 小时测量心率(HR)、中心静脉压(CVP)、平均动脉压(MAP)、肺毛细血管楔压(PCWP)、心指数(CI)、全身血管阻力指数(SVRI)、肺动脉压(PAP)和肺血管阻力指数(PVRI)。
移植后 24 小时仍存在高动力循环,CI 分别为 5.4±1.3L/(min×m2)和 4.9±1.0L/(min×m2),在病毒性和酒精性组中分别升高,且 SVRI 降低。在最初的 24 小时内,HR 显著下降,MAP 升高;两组变化程度相似。CVP、PCWP 和 SVRI 增加,CI 降低,但病毒性组中,酒精性组没有发生这种变化。与病毒性组相比,酒精组在 24 小时时的 PVRI(119±52 dynes/(cm5×m2)比 166±110dynes/(cm5×m2),P<0.05)和 PAP(20±7mmHg 比 24±7mmHg,P<0.05)较低。
移植后即刻高动力循环持续存在,且病毒性组的改善更快。酒精性患者有更明显的肺血管扩张。
