There were significant differences between these mean PaCO2 values. The mean leukotriene B4 levels on the three occasions were correlated with the mean PaCO2 values. Thus, leukotriene B4 levels in arterial blood reflect the severity of asthmatic attacks and may be affected by intravenous prednisolone. ER -
