Introduction:
Thoracic injuries account for 20-25% of trauma-related deaths. In cases of pneumothorax the insertion of a chest tube is mandatory but associated with high complication rates particularly when inserted under difficult conditions. The C-Lant is a novel chest-tube insertion device that provides integrated double fixation capabilities and can be used by responders with minimal experience. The aim of the study was to test the device in a large animal model.
Material And Methods:
Pneumothorax, tension pneumothorax, and hemothorax were induced in four white domestic female pigs. The C-Lant device (Vigor Medical Technologies, Haifa, Israel) was inserted as any chest-drain to decompress the thorax. Pull test was applied to test the strength of device fixation.
Results:
The insertion of the device was simple and effective without detectable negative physiological effects. Reliable fixation was achieved without difficulty. Air and liquid were promptly drained from the chest cavity. Minimal tissue laceration occurred when applying the device in a scenario of erroneous pneumothorax diagnosis with fully expanded lungs. Interconnection with other surgical accessories was smooth.
Conclusion:
The C-Lant is a novel device that facilitates easy insertion and fixation of chest-tubes by minimally experienced medical providers and reduces the likelihood of unwanted expulsion. Clinical studies are planned.
