Dunne CL, et al. - As an obstructed airway (choking) has a considerable mortality burden globally, with increasing incidence, despite it being a relatively preventable injury, researchers sought to ascertain the effectiveness of anti-choking suction devices at relieving obstructions via performing this systematic review. Searching Ovid MEDLINE, Embase, PubMed, The Cochrane Library, SCOPUS, Web of Science, CINAHL Plus and the English websites of the devices, they included five studies that reported the anti-choking devices’ dislodgment success rate (primary outcome) or associated adverse events (secondary outcome). The available data had many weaknesses and there were few unbiased trials that test the effectiveness of anti-choking suction devices. This resulted in inadequate evidence to encourage or discourage their use. Several devices have been manufactured worldwide, however, the most extensively studied device is the LifeVac, with a combined dislodgement success rate of 94.3% on the first attempt. For the primary outcome, the certainty of evidence was evaluated as very low. In view of these findings, they recommend practitioners to continue to adhere to guidelines provided by local resuscitation authorities which align with ILCOR recommendations.
