Abstract

Background: An infusion pump designed to deliver a specific volume at a predetermined rate is unable to detect extravasation and may continue infusion despite increased tissue resistance caused by extravasation. Consequently, it is recommended that vesicant drugs, such as chemotherapeutic agents, be administered via gravity infusion to reduce the risk of tissue damage. However, intravenous flow regulators used for gravity infusion have limitations because the infusion rate is influenced by the height, venous pressure, and viscosity of the fluid, which can change with temperature. In this study, we measured the accuracy of Accudrip, a new gravity-based automatic infusion control device designed to correct fluctuating infusion rates.

Methods: In 59 cancer patients administered with anticancer drugs, the actual administration rate using Accudrip under various administration conditions and the theoretical administration rate were measured and analyzed 100 times.

Results: Comparing the theoretical and actual administration rates using Accudrip confirmed that it can be injected with an average error rate of 4.75%, which clinically demonstrated sufficient accuracy for fluid administration.

Conclusion: The gravity-based automatic infusion system showed high accuracy consistent with the theoretical rate of administration even under multiple infusion conditions of cancer patients with chemoport. This system (Accudrip) will greatly contribute to accurate drug administration and minimization of adverse events in real-world hospital settings.

重力自动输注系统在化学港静脉输注中的准确性。
背景:设计以预定速率输送特定体积的输注泵无法检测到外渗,尽管外渗引起组织阻力增加,但仍可能继续输注。因此,建议通过重力输注给药,如化疗药物,以减少组织损伤的风险。然而,用于重力输液的静脉流量调节剂存在局限性,因为输液速率受高度、静脉压和液体粘度的影响,而这些会随着温度的变化而变化。在这项研究中,我们测量了Accudrip的准确性,Accudrip是一种新的基于重力的自动输液控制装置,旨在纠正输液速率的波动。方法:对59例肿瘤患者在不同给药条件下使用Accudrip的实际给药率和理论给药率进行100次测定和分析。结果:比较Accudrip的理论给药率和实际给药率,证实其可注射,平均误差率为4.75%,临床证明其给药准确性足够。结论:基于重力的自动输注系统即使在多种输注条件下也具有较高的准确性,符合理论给药率。该系统(Accudrip)将极大地有助于准确的给药和最小化不良事件在现实世界的医院设置。
