Abstract:
Background The use of double external defibrillation (DED) in refractory cardiac arrest has been gaining increasing interest in recent years. Unlike traditional defibrillation, DED uses two defibrillators, either simultaneously or sequentially, to deliver shocks. This approach aims to maximize the probability of restoring normal heart rhythm when conventional techniques fail. While a number of studies have examined the use of DED in the pre-hospital setting, data on its use in the hospital setting, particularly in the emergency department, is significantly lacking. Objective: Synthesize current knowledge on the use of DED in hospital settings, focusing on reported practices and challenges arising from its implementation. Methods: A quick review of the literature was conducted, in accordance with the methodological recommendations of the Cochrane Rapid Review Working Group (Garritty et al., 2024). Databases consulted included PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library. Results: The initial search identified 356 articles published between 2004 and 2024. Fifteen articles were selected, detailing 18 case reports. Analysis of the cases helped to identify the potential benefits, limitations and risks associated with the use of DED in a hospital setting. Conclusion: DED is generally used as a last resort, after traditional methods have failed. At present, the limited robustness of available studies does not allow us to establish its efficacy in comparison to simple defibrillation. Thus, randomized controlled trials are required to confirm its efficacy. For future practice, the uniqueness of clinical cases must be taken into account, and healthcare teams must consider a risk-benefit analysis for prolonged resuscitation. Standardization of procedures will also be essential to ensure optimal use of DED.
