Propionic acidemia is an inborn error of metabolism characterized by accumulation of propionic acid due to deficiency of propionyl-CoA carboxylase. Main stay of treatment focuses on reducing dietary protein. However, orthotropic liver transplantation decreases the frequency of metabolic decompensations and improves life expectancy. We report a case of a 4-year-old boy undergoing orthotropic liver transplantation to treat propionic acidemia. This case highlights the use of intraoperative monitoring of metabolic markers like urine ketones, arterial ammonia, and lactate levels as these patients are at risk for hyperammonemia and metabolic acidosis. Also, the relevance in outcomes when performing early extubation in fast-tracking recovery.
丙酸血症是一种先天性代谢缺陷病,由于丙酰基辅酶 A 羧化酶缺乏,导致丙酸积累。治疗的主要重点是减少饮食中的蛋白质。然而,原位肝移植可降低代谢失代偿的频率并提高预期寿命。我们报告了一例 4 岁男孩接受原位肝移植治疗丙酸血症的病例。该病例强调了术中监测代谢标志物(如尿酮体、动脉氨和乳酸水平)的重要性,因为这些患者存在高氨血症和代谢性酸中毒的风险。此外,快速康复时早期拔管对预后的相关性。
