BiPAP for treating moderate and severe asthma exacerbations in a PED


BiPAP utilization for the treatment of severe refractory status asthmaticus patients has become an accepted therapy but is not well described for moderate exacerbations. We sought to analyze outcomes from our BiPAP quality database for children presenting in status asthmaticus at varying levels of severity.


PED status asthmaticus patients requiring BiPAP from 1 January 2010 to 31 August 2012 had a bedside interview and documentation of information at the time therapies were given. Incomplete data were collected retrospectively. All data were stored and analyzed using a RedCap database. Subjects were stratified into severity groups based on asthma score at the time of BiPAP placement.


There were 206 subjects in the moderate severity group and 197 in the severe group. Table 1 shows the groups were well matched and compares other pertinent data. Children with severe presentations were placed on BiPAP sooner (P < 0.001) and remained on BiPAP longer (P < 0.001). The moderate group had a longer wait until BiPAP placement. Tables 2 and 3 demonstrate higher initial BiPAP (IPAP/EPAP) settings with increasing age and severity. Figure 1 trends initiation and termination asthma scores stratified by severity at BiPAP placement. More of the severe group was admitted to the PICU andhad overall longer hospitalizations (P < 0.06). None experienced severe complications.

BiPAP is a benefi cial therapy for children presenting to the PED with severe asthma exacerbations. It may have utility for less severe asthma exacerbations.
