This study was performed to evaluate the efficacy of a novel chest drainage system. This system employs guide wire-based active chest tube clearance to improve drainage and maintain patency. A 32 Fr chest tube was inserted into pleural cavities of five pigs. On the left, a tube was connected to the chest canister, and on the right, the new system was inserted between the chest tube and chest canister. Acute bleeding was mimicked by periodic infusion of blood. The amount of blood drained from each chest cavity was recorded every 15 min for 2 h. After completion of the procedure, all residual blood and clots in each chest cavity were assessed. The new system remained widely patent, and the amount of drainage achieved with this system (670+/-105 ml) was significantly (P=0.01) higher than that with the standard tube (239+/-131 ml). The amount of retained pleural blood and clots with this system (150+/-107 ml) was significantly (P=0.04) lower than that with the standard tube (571+/-248 ml). In conclusion, a novel chest drainage system with active tube clearance significantly improved drainage without tube manipulations.
本研究旨在评估一种新型胸腔引流系统的疗效。该系统采用基于导丝的主动胸管清理技术来改善引流并保持通畅。将一根32F的胸管插入5头猪的胸腔。左侧的胸管连接到胸腔罐，右侧则将新系统插入胸管与胸腔罐之间。通过定期输注血液来模拟急性出血。每15分钟记录每个胸腔引流的血液量，持续2小时。手术完成后，评估每个胸腔内所有残留的血液和血凝块。新系统保持广泛通畅，该系统实现的引流量（670±105ml）显著（P = 0.01）高于标准胸管（239±131ml）。该系统残留的胸腔血液和血凝块量（150±107ml）显著（P = 0.04）低于标准胸管（571±248ml）。总之，一种具有主动胸管清理功能的新型胸腔引流系统在无需进行胸管操作的情况下显著改善了引流效果。
