Abstract

Background: A patent dual-lumen dialysis catheter is one of the basic requirements for efficient extracorporeal (EC) therapy.

Aims: The objective of this study was to measure the resistance to blood flow offered by straight and curved-extension dual-lumen dialysis catheters used for continuous renal replacement therapy (CRRT).

Methods: Twenty dogs suffering from acute kidney injury (AKI) were subjected to CRRT. The dogs were allocated randomly to Group-I (curved extension catheter, n=12) or Group II (straight extension catheter, n=8), based on the type of dual-lumen catheter used in CRRT. The catheter outflow and inflow pressures were recorded at blood pump speeds of 50 ml/min and 99-100 ml/min. Data were tested for normality, and differences in mean inflow and outflow catheter resistances were evaluated for statistical significance using independent samples t-tests.

Results: Straight extension catheters offered lower inflow resistance than curved extension catheters at both 50 ml/min (41.50 ± 5.84 mm Hg vs. 63.75 ± 6.88 mm Hg, P=0.03) and 99-100 ml/min (63.00 ± 8.11 mm Hg vs. 86.92 ± 7.02 mm Hg, P=0.04) blood flow rates. Straight extension catheters also offered lower outflow resistance than curved catheters at 99-100 ml/min blood flow rate (-94.12 ± 7.91 mm Hg vs. -128.25 ± 7.56 mm Hg, P=0.01; the negative signs only indicate the direction of blood flow).

Conclusion: These findings suggest that straight-extension dual-lumen dialysis catheters perform better than the curved model in extracorporeal renal replacement therapy by considering their lower resistance to blood flow.

对用于急性肾损伤犬持续肾脏替代疗法的直式和弯式延伸透析导管进行比较评估。

背景：目的：本研究的目的是测量用于持续肾脏替代治疗（CRRT）的直管和弯管双腔透析导管的血流阻力：方法：20 只患有急性肾损伤（AKI）的狗接受了 CRRT 治疗。根据 CRRT 中使用的双腔导管类型，这些狗被随机分配到第一组（弯曲延伸导管，12 只）或第二组（直延伸导管，8 只）。在血泵速度为 50 毫升/分钟和 99-100 毫升/分钟时记录导管流出和流入压力。对数据进行了正态性检验，并使用独立样本 t 检验对导管流入和流出平均阻力的差异进行了统计学意义评估：结果：在 50 毫升/分钟（41.50 ± 5.84 mm Hg vs. 63.75 ± 6.88 mm Hg，P=0.03）和 99-100 毫升/分钟（63.00 ± 8.11 mm Hg vs. 86.92 ± 7.02 mm Hg，P=0.04）血流速度下，直伸导管的流入阻力均低于弯伸导管。在血流量为 99-100 毫升/分钟时，直伸导管的流出阻力也低于弯曲导管（-94.12 ± 7.91 mm Hg vs. -128.25 ± 7.56 mm Hg，P=0.01；负号仅表示血流方向）：这些研究结果表明，考虑到直伸型双腔透析导管的血流阻力较小，因此在体外肾脏替代疗法中其性能优于弯曲型。
