Which is more effective for ventilation in the prehospital setting during cardiopulmonary resuscitation, the laryngeal mask airway or the bag-valve-mask? - A review of the literature

摘要: Introduction Prehospital care providers are responsible for providing adequate ventilation during cardiopulmonary resuscitation (CPR). Endotracheal intubation (ETI) is widely accepted as the 'gold standard' airway protection and preferred method ventilation. However, most Australian paramedics not trained to perform ETI. Laryngeal Mask Airway (LMA) Bag-Valve-Mask (BVM) seen alternatives ETI recommended by International Liaison Committee of Resuscitation (ILCOR). The objective this study was identify which device LMA or BVM (with OPA/NPA) more effective in patency prehospital environment. Methods A literature search conducted using medical electronic databases, MEDLINE CINHAL, EMBASE, Meditext, Cochrane Central Register Controlled Trials (CENTRAL), Scopus. These databases were searched from January 1996 until end 2010. Articles included if principal compare efficiency against setting. References articles retrieved reviewed. Results There 2937 located search. Of these, 30 met inclusion criteria with twelve relevant In studies, two involved use mannequins, four retrospective, five observational, there one a review. Conclusion findings review suggest that at ventilations over time CPR adults, less risk gastric regurgitation pulmonary aspiration. quicker performing first but loss effectiveness time. considered best ventilating children neonates.
