Efficacy of double-lumen intubation performed by paramedics on patients with lung damage. Experimental, pilot simulation trial
, 2, 3, 4, 5
Abstract
INTRODUCTION: The airway management and the implementation of optimal oxygen therapy in trauma patients, especially unconscious ones, is a key element of prehospital management. However, in cases of trauma lung or bronchial rupture, both lungs ventilation may not be advisable. In such cases, intubation with a double-lumen endotracheal tube may be helpful, allowing to provide one-lung ventilation. The aim of the experimental study was to assess the impact of short training in intubation using double-lumen tubes on the effectiveness of intubation performance and one-lung ventilation by paramedics in a simulated trauma patient setting.
MATERIAL AND METHODS: This was a prospective, observational, randomized experimental trial. The study involved 30 paramedics. The participants had to perform tracheal intubation using Double Lumen Tube VivaSight-DL (VS-DL; ETView Ltd.; Misgav, Israel) under normal airway conditions. The effectiveness of the first intubation attempt, the time of intubation and the Cormack-Lehane scale were evaluated.
RESULTS: The effectiveness of the first attempt at intubation with a double-lumen tube was 90% and the total effectiveness of intubation was 100%. The median time of the procedure was 63 (IQR; 38–72.5) seconds.
CONCLUSIONS: In the simulation study, the paramedics were able to intubate using a double tube after a short training.
