摘要

目的:探讨一种新的机械化淋巴引流方法通过胸导管淋巴引流部位局部降低静脉压在急性失代偿性心力衰竭(ADHF)模型中的应用效果。材料和方法。该装置的主要部件是一根内置进出机械阀的导管,设计用于通过左颈内静脉插入左头臂静脉。它配备了一个体外驱动系统,作为一个无阀脉动泵,具有10毫升冲击放电和一个控制器,确保预设频率和压力/稀薄占空比。该装置的工作原理是在胸导管淋巴引流部位(左颈内静脉和锁骨下静脉交界处)局部降低静脉压。在水动力试验台模拟ADHF条件下的水动力学时,通过左头臂静脉的上静脉流量为0.4 l/min,胸导管淋巴引流部位的压力由20-25 mmHg降至0-5 mmHg,原因是使用了机械化引流装置,吸入/注射相时比为0.2/0.8,脉动泵工作频率为30 ~ 60次/min。

Mechanized lymphatic drainage in acute decompensated heart failure. A study on a hydrodynamic test bench
Objective: to investigate the effectiveness of a new mechanized lymphatic drainage method in acute decompensated heart failure (ADHF) modeling through local reduction in venous pressure in the site of lymphatic drainage from the thoracic duct.Materials and methods. Main components of the device are a catheter with built-in inlet and outlet mechanical valves designed for insertion into the left brachiocephalic vein through the left internal jugular vein. It comes with an extracorporeal drive system made as a valveless pulsator pump with a 10 ml shock discharge and a controller ensuring preset frequency and pressure/rarefaction duty cycle. The operating principle of the device is based on local reduction of venous pressure in the site of lymphatic drainage from the thoracic duct (in the junction of the left internal jugular and subclavian veins).Results. When modeling hydrodynamics under ADHF conditions on a hydrodynamic test bench, the upper venous flow through the left brachiocephalic vein was 0.4 l/min, the pressure in the site of lymphatic drainage from the thoracic duct, was decreased from 20–25 mmHg to 0–5 mmHg due to operation of the mechanized drainage device with suction/injection phase duration ratio 0.2/0.8 and pulsator pump operating frequency from 30 to 60 beats/min.
