Abstract:
Objective To investigate the clinical value of laryngeal mask airway (LMA) in patients with a-cute severe asthma(ASA). Methods 32 patients with ASA treated with LIMA or mouth-nose mask during 2002 -2009 in our hospital were retrospectively analyzed. Those treated with laryngeal mask airway was taken as observation group and those with Mouth-nose mask as control group. Results The period to oxygen saturation in arterial blood, the time to remove ventilator, and the time to disease improvement in the observation group (389.63±32.82)s, (19.31±2.26) hours,(16.22±3.85) hours were different from that in control group (467.36±41.15) s, (25.18±3.73) hours,(23.66±2.38) hours (P<0.01). After non-invasive positive pressure ventilation, PaCO_2 decreased, PaO_2 and pH increased at 3 and 12 hours in the observation group (P<0.05 or 0.01) from that before treatment. PaCO_2 and pH at 3 hours in the control group were no significant difference before and after treatment (P > 0.05),with an exception of PaO_2 (P < 0.05). PaCO_2, PaO_2 and pH were significantly different (P < 0.05) at 12 hours after treatment from those before treatment. Conclusions LMA should be considered in the selection of non-invasive positive-pressure ventilation (NIPPV) in patients with ASA, for a better improvement of ventilation ef-fectivenoss and accelerating the mitigation of clinical manifestations.
