Ischemia-free liver transplantation (IFLT) prevents ischemia-reperfusion injury (IRI) and reduces IRI-related complications. In this study, we explored the protective effects of IFLT on myocardial injury after noncardiac surgery (MINS) and postoperative pulmonary complications (PPCs).
Sixty-five patients who underwent liver transplantation were enrolled in this post hoc analysis of the IFLT-DBD trial. Intraoperative pulse indicator continuous cardiac output, pulmonary artery catheter, and blood gas parameters were prospectively collected.
The incidence of MINS did not differ between the two groups (28.1% vs. 45.5%, P = 0.147), although the peak high-sensitive troponin level was significantly lower in the IFLT group than in the conventional liver transplantation (CLT) group (0.056 ± 0.007 vs. 0.088 ± 0.016 ng/mL, P = 0.036). The incidence of PPCs was lower in the IFLT group than in the CLT group (37.5% vs. 66.7%, P = 0.019). Multivariate analysis revealed that IFLT was an independent protective factor against PPC. The median duration of ventilation was significantly shorter in the IFLT group than in the CLT group [12.5 (3.5-21.5) vs. 18 (0-69.5) hours, P<0.001].
The use of IFLT is associated with lower peak troponin T level and lower incidence of PPC.
无缺血肝移植（IFLT）可预防缺血再灌注损伤（IRI）并减少与IRI相关的并发症。在本研究中，我们探讨了IFLT对非心脏手术（MINS）后心肌损伤和术后肺部并发症（PPCs）的保护作用。
65例行肝移植的患者纳入了IFLT-DBD试验的这项事后分析。前瞻性收集术中脉搏指示连续心输出量、肺动脉导管和血气参数。
两组间MINS的发生率无差异（28.1%对45.5%，P = 0.147），尽管IFLT组的高敏肌钙蛋白峰值水平显著低于传统肝移植（CLT）组（0.056±0.007对0.088±0.016 ng/mL，P = 0.036）。IFLT组的PPCs发生率低于CLT组（37.5%对66.7%，P = 0.019）。多因素分析显示IFLT是预防PPC的独立保护因素。IFLT组的中位通气时间显著短于CLT组[12.5（3.5 - 21.5）对18（0 - 69.5）小时，P<0.001]。
使用IFLT与较低的肌钙蛋白T峰值水平和较低的PPC发生率相关。
