摘要

目的比较体内心脏移植物 6 小时常温自体灌注与使用 Bretschneider 溶液（Custodiol，Dr Franz Köhler Chemie GmbH，德国本斯海姆）进行药冷保存的效果：方法：选择体重为 50 ± 5 千克、年龄为 4-5 个月大（n = 10）的陆地猪作为一系列急性实验的模型。对实验组（5 头）进行 6 小时的自灌注心肺调节。另一方面，对照组使用布氏溶液进行 6 小时药冷保存，以恢复心脏的泵血功能。通过测量血流动力学参数、心跳和心肌缺血标志物浓度来评估移植物保存效果：结果：再灌注和分离工作心肺复合体后，实验组和对照组的心输出量分别为 0.63 [0.37; 0.8] L/min 和 0.37 [0.23; 0.37] L/min（P < .05）。对照组冠状动脉窦血中 CPK-MB、LDH、肌钙蛋白-I 和乳酸的水平明显更高：结论：该研究表明，与使用布氏溶液进行 6 小时体外移植物调理的药冷保存相比，常温自体灌注在维持供体心脏形态功能状态方面具有明显优势。2023年7月16日收到。2023年9月8日修订。2023年9月11日接受。资助：本研究在第 23-25-10013 号项目框架内进行（2023 年 4 月 20 日与俄罗斯科学基金会签订的第 23-25-10013 号协议，2023 年 4 月 3 日与新西伯利亚州科学与创新政策部签订的第р-52 号协议）。利益冲突：作者声明无利益冲突。作者的贡献构思和研究设计：M.O.

Long-term normothermic autoperfusion of the cardiopulmonary complex ex vivo as a method of effective graft conditioning: an experimental study

Objective: To compare the effectiveness of 6-hour normothermic autoperfusion of a heart graft ex vivo with pharmaco-cold preservation using Bretschneider's solution (Custodiol, Dr Franz Köhler Chemie GmbH, Bensheim, Germany).Methods: Landrace pigs weighing 50 ± 5 kg and aged 4–5 months (n = 10) were selected as a model for a series of acute experiments. Cardiopulmonary conditioning using autoperfusion was conducted for 6 hours on the experimental group (n = 5). On the other hand, the control group underwent a 6-hour pharmaco-cold preservation with Bretschneider solution to recover the heart's pumping function. Graft preservation effectiveness was evaluated by measuring hemodynamic parameters, heartbeat, and myocardial ischemia marker concentrations.Results: After reperfusion and isolation of the working cardiopulmonary complex, cardiac output was 0.63 [0.37; 0.8] L/min and 0.37 [0.23; 0.37] L/min in the experimental and control groups, respectively (P < .05). The levels of CPK-MB, LDH, troponin-I, and lactate in the coronary sinus blood was significantly higher in the control group.Conclusion: The study demonstrated significant benefits of normothermic autoperfusion in maintaining the morphofunctional status of the donor heart compared to pharmaco-cold preservation using Bretschneider's solution for 6 hours of ex vivo graft conditioning.
