肝硬化患者的大量肺出血是一种危及生命的并发症,由于其死亡率高,可能导致肝移植禁忌症。在此,我们提出两例婴儿胆道闭锁的病例,他们成功地接受了LDLT,随后对移植前大量肺出血进行了重症呼吸护理。两例病例均表现出重度呼吸衰竭(最低PaO 2/FiO 2;分别为46 mmHg和39 mmHg)。为了阻止出血,我们应用了极高正压通气治疗(最大PIP/PEEP;分别为38/14 cmH 2 O和55/15 cmH 2 O)、血浆置换、多次FFP输注和经肺内给药的重组凝血因子VIIa。此外,我们使用CHDF治疗,短暂应用HFOV,并吸入一氧化氮治疗患者。尽管我们准备了术中使用的ECMO,但这两例病例均成功地使用了传统机械通气,而没有使用ECMO,这可能由于使用抗凝剂而使肺出血恶化。使用过度正压管理,虽然它会造成气压伤的风险,但对于在LDLT前没有时间的肝衰竭患者的选定病例中阻止肺出血是可以接受的。
A massive pulmonary hemorrhage in patients with liver cirrhosis is a life‐threatening complication that may result in a contraindication of a liver transplantation because of its high mortality rate. Herein, we present two infant biliary atresia cases that successfully underwent an LDLT that was followed by intensive respiratory care for the pretransplant massive pulmonary hemorrhage. Both cases exhibited severe respiratory failure (minimum PaO2/FiO2; 46 mmHg and 39 mmHg, respectively). To arrest the bleeding, we applied a very high positive pressure ventilation treatment (maximum PIP/PEEP; 38/14 cmH2O and 55/15 cmH2O, respectively), plasma exchange, several FFP transfusions, and recombinant factor VIIa via intrapulmonary administration. In addition, we used CHDF treatment, applied HFOV transiently, and treated the patient with inhalation of nitric oxide. Although we prepared ECMO for intra‐operative use, both cases were successfully managed with conventional mechanical ventilation without using ECMO, which may have worsened the pulmonary hemorrhage due to the use of an anticoagulant. Use of an excessive positive pressure management, although it poses a risk for barotrauma, could be acceptable to arrest the pulmonary bleeding in selected cases of liver failure patients who have no time remaining before LDLT.
