Observation on the effect of emergency airway established by laryngeal mask for cerebral protection / 中国医学装备

ABSTRACT

Objective:To observe the effect of emergency airway established by laryngeal mask for cerebral protection, and to popularize using laryngeal mask for establishing emergency airway in cardiopulmonary resuscitation(CPR) among paramedics.Methods:To compare the rescuing effect, 49 cases of patients with cardiac arrest were divided into 2 groups as different rescue method: laryngeal mask group (23 cases), emergency airway established by laryngeal mask airway(LMA); face mask group (26 cases).Results: After aerating 5 minutes, the average oxyhemoglobin saturation has recovered to 94.1% in laryngeal mask group, and it was 78% in face mask group; heartbeat recovery rate was 100% in laryngeal mask group, and face mask group was 84.62%, and there was no statistical significant (x2=2.94,P>0.05); breathing recovery rates were 86.96% and 19.23%, respectively, in laryngeal mask group and face mask group, and there was statistical significant (x2=19.772,P<0.05); consciousness recovery rates were 43.48% and 7.69%, respectively, between the two groups, and there was statistical significant (x2=6.627,P<0.05). Conclusion: Compared with the face mask group, to establish airway for cardiac arrest patient by using laryngeal mask airway(LMA) would got efficient results in improving anoxia in cerebral, increasing spontaneous breath rate and consciousness recovery rate.
