    • 心血管生理学心血管生理学
    • 手术支持技术 手术支持技术

    背景情况:

    • 系统静脉循环需要在右心绕行手术后提供支持.
    • 丰坦手术涉及右心室到肺动脉解剖,它带来了独特的循环挑战.

    研究的目的:

    • 评估相位外体压缩作为循环支持方法的有效性.
    • 评估该技术对Fontan手术后患者血液动力学参数的影响.

    主要方法:

    • 实验研究涉及急性右心旁路与相位外部压缩 (60毫米升,6-8周期/分钟).
    • 临床试验在9名接受Fontan手术的患者中,使用相位外部压缩 (每分钟45-50mm Hg,45秒打开,15秒关闭).

    主要成果:

    • 实验压缩使右心房压增加了44%,心脏指数增加了21%.
    • 在临床试验中,压缩使右心房压升高了44%,静脉压升高了30%.
    • 只有两名患者需要手术后服用内类药物;其他患者接受了很少或没有血管活性药物.

    结论:

    • 身体下部的相位外部压缩是一种简单而有效的循环辅助方法.
    • 这种技术在Fontan手术后改善血液动力学稳定性方面表现有前途.
