BACKGROUND/AIM: Penetrating heart injuries result in high mortality. We designed a new catheter to facilitate the treatment of penetrating cardiac injuries and provide more effective initial bleeding control and fluid replacement.
The cardiac injury model was applied to 8 female 1-year-old Sus domesticus pigs. Subjects were grouped according to whether a Foley catheter or a newly designed catheter was placed into the heart through cardiac lacerations. Changes in systolic blood pressures, mortality, and problems encountered during surgery and other intraoperative findings were recorded.
There were higher mean blood pressure measurements in the newly designed catheter group during stages IV to VII. All subjects had tamponade and cardiac activity after completion of the repair of all lacerations in the catheter group, whereas in the other group only one subject did. Intraoperative direct fluid infusion to the heart through the catheters in the diastole was performed in all subjects of both groups. However, regurgitation from the cardiac cavity in the systole was seen only in the Foley catheter group. All of the intraoperative complications were seen in the same group.
背景/目的：穿透性心脏损伤可导致高死亡率。我们设计了一种新的导管，以方便治疗穿透性心脏损伤，并提供更有效的初始出血控制和液体替代。
将心脏损伤模型应用于 8 只 1 岁雌性家猪。根据是否通过心脏裂伤将 Foley 导管或新设计的导管放置到心脏，对研究对象进行分组。记录收缩压变化、死亡率以及手术中遇到的问题和其他术中发现。
在第四至第七阶段，新设计的导管组的平均血压测量值更高。在导管组中，所有的裂伤修复完成后，所有的研究对象均有心包填塞和心脏活动，而在另一个组中，只有 1 个研究对象出现这种情况。在两组的所有研究对象中，均在舒张期通过导管直接向心脏输注液体。然而，只有在 Foley 导管组中，在收缩期才看到从心脏腔反流。所有术中并发症均出现在同一组中。
