Comparative Analysis of Analog and Digital Chest Tube Drainage Systems Using a High‐Fidelity 3D‐Printed Neonatal Chest Model

This experimental study evaluates the suitability of digital drainage systems for the pediatric and neonatal populations. Our model demonstrated reliable simulation of thoracic conditions, making it a useful tool for pre-clinical testing where patient testing may be limited. Both systems yielded satisfactory results at -20 and -10 cmH₂O, but the digital system showed greater flexibility, maintaining pressures as low as -5 cmH₂O. The analog system was consistent but less adaptable, which may limit its use in dynamic situations. The digital system's ability to simulate more flexible scenarios offers potential clinical advantages, though further investigation is needed to assess its impact on neonatal safety. The increase in suction during flushing may pose a risk for neonatal patients.
