Réalité augmentée et sauvetage au combat: Bientôt ?

Using augmented reality as a clinical support tool to assist combat medics in the treatment of tension pneumothoraces.

La réalité augmentée désigne les systèmes informatiques qui rendent possible la superposition d'un modèle virtuel 3D ou 2D à la perception que nous avons naturellement de la réalité et ceci en temps réel. La commercialisation récente des Google glass est le témoin d'une technologie qui devient mature. Dès lors il n'est pas étonnant qu'un tel dispositif soit utilisé dans les domaines de la formation voire en conditions réelles.  Le travail présenté ci-après n'est qu'un exemple.

This study was to extrapolate potential roles of augmented reality goggles as a clinical support tool assisting in the reduction of preventable causes of death on the battlefield. Our pilot study was designed to improve medic performance in accurately placing a large bore catheter to release tension pneumothorax (prehospital setting) while using augmented reality goggles. Thirty-four preclinical medical students recruited from Morehouse School of Medicine performed needle decompressions on human cadaver models after hearing a brief training lecture on tension pneumothorax management. Clinical vignettes identifying cadavers as having life-threatening tension pneumothoraces as a consequence of improvised explosive device attacks were used. Study group (n = 13) performed needle decompression using augmented reality goggles whereas the control group (n = 21) relied solely on memory from the lecture. The two groups were compared according to their ability to accurately complete the steps required to decompress a tension pneumothorax. The medical students using augmented reality goggle support were able to treat the tension pneumothorax on the human cadaver models more accurately than the students relying on their memory (p < 0.008). Although the augmented reality group required more time to complete the needle decompression intervention (p = 0.0684), this did not reach statistical significance.
