Abstract

Background: To date, several chest drainage systems are available, such as digital drainage systems (DDS) and traditional systems with continuous suction or water seal. However, none of these systems were yet shown to be favorable in the treatment of complex situations such as persistent air leaks or residual spaces. We present in-vitro as well as clinical data of a novel hybrid drainage system consisting of an optimized digital drainage system (ODDS) and an underwater seal drainage system (UWSD).

Methods: For in-vitro analysis, a DDS and an ODDS were connected to a pleural cavity simulator. Different air leaks were produced and data on intrapleural pressure and air flow were analyzed. Furthermore, we tested the hybrid drainage system in 10 patients with potential air leaks after pulmonary surgery.

Results: In in-vitro analysis, we could show, that with advanced pump technology, pressure fluctuations caused by the drainage system when trying to maintain a set pressure level in patients with airleaks were much smaller when using an ODDS and could even be eliminated when using a fluid collection canister with sufficient buffer capacity. This minimized air leak boosts caused by the drainage system. Optimizing the auto-pressure regulation algorithms also led to a reduced airflow through the fistula and promoted rest. Switching to a passive UWSD also reduced the amount of airflow. Clinical application of the hybrid drainage system yielded promising results.

Conclusion: The novel hybrid drainage system shows promising results in the treatment of patients with complex clinical situations such as persistent air leaks.

混合式(数字/水封)胸腔引流系统--一种适用于预期漏气患者的创新设备。
背景:迄今为止,已有多种胸腔引流系统可供选择,如数字引流系统 (DDS) 和带持续抽吸或水封的传统系统。然而,这些系统均未显示出对治疗复杂情况(如持续漏气或残余空间)的优势。我们展示了由优化数字引流系统(ODDS)和水下密封引流系统(UWSD)组成的新型混合引流系统的体外和临床数据:为了进行体外分析,将 DDS 和 ODDS 连接到胸膜腔模拟器上。方法:为了进行体外分析,将 DDS 和 ODDS 连接到胸膜腔模拟器上,产生不同的漏气现象,并分析胸膜腔内压力和气流数据。此外,我们还在 10 名肺部手术后可能出现漏气的患者身上测试了混合引流系统:体外分析表明,采用先进的泵技术,当使用 ODDS 时,引流系统在试图维持漏气患者的设定压力水平时引起的压力波动要小得多,而当使用具有足够缓冲能力的液体收集罐时,压力波动甚至可以消除。这最大限度地减少了引流系统造成的漏气增压。优化自动压力调节算法也减少了通过瘘管的气流,促进了休息。改用被动式 UWSD 也减少了气流量。混合引流系统的临床应用取得了良好的效果:结论:新型混合引流系统在治疗持续漏气等复杂临床情况的患者方面显示出良好的效果。

期刊介绍: Surgical Innovation (SRI) is a peer-reviewed bi-monthly journal focusing on minimally invasive surgical techniques, new instruments such as laparoscopes and endoscopes, and new technologies. SRI prepares surgeons to think and work in "the operating room of the future" through learning new techniques, understanding and adapting to new technologies, maintaining surgical competencies, and applying surgical outcomes data to their practices. This journal is a member of the Committee on Publication Ethics (COPE).
