Uso da máscara laríngea em pacientes com parada cardiorrespiratória: revisão sistemática

Abstract

The objective of this study was to analyze the survival, ventilation effectiveness and the occurrence of regurgitation associated to the utilization of the laryngeal mask in patients with cardiopulmonary arrest. This systematic review was performed using the LILACS, Embase, CINAHL, MEDLINE and Cochrane databases. Thirteen studies were selected: two clinical trials, being one randomized controlled trial and one not controlled; and eleven descriptive studies. The randomized controlled trial showed a 7% survival rate for patients who utilized the laryngeal mask, but no statistical difference was found compared to other airway devices. Pulmonary ventilation was effective in both the subjective and the objective evaluations. Regurgitation was observed in three cases, but the frequency showed no statistical differences between groups. The results of this systematic review indicate the need to perform randomized controlled studies to analyze the benefits of using the laryngeal mask in cardiopulmonary resuscitation.
