Steroids in COPD. The scripture according to Albert.

We were interested by the possible association between the control serum K levels and maximum decrease in serum K after 3,-adrenergic drug administration described by Raimondi et al. When we re-examined our data in this light there was no linear correlation found in the group that received IM albuterol (r = . 10), a weak correlation in the IV albuterol group (r .50) and a good linear correlation in the SC albuterol group (r = . 79). Overall our data may suggest a linear correlation between control serum K and the maximum decrease in serum K but certainly not as strongly as the data shown by Raimondi et al (r = . 87). Unfortunately, the authors do not mention whether or not their subjects had recently received any
