RESUMO
Cardiopulmonary arrest in children frequently has a respiratory cause. Bradycardia and asystole result from the hypoxia and acidosis of inadequate ventilation. Fortunately, respiratory failure presents warning signs which make early intervention and prevention of arrest a major focus for the nurse. When cardiopulmonary arrest does occur, the nurse must be able to provide the A-B-C's of basic life support, to participate actively in definitive treatment of the arrest, and to assess the child carefully during the post-resuscitation recovery stabilization period.

A chemiluminescent assay coupled to a periodide extraction method is described for the measurement of acetylcholine release from the vascular perfused rat phrenic nerve-hemidiaphragm preparation. A direct comparison of the chemiluminescent assay with an established radioenzymatic assay for acetylcholine demonstrates that the two assays are quantitatively equivalent and yield similar limits of sensitivity of approximately 2 pmol, and that the periodide extraction/chemiluminescent assay method is more consistent than the tetraphenylboron extraction/radioenzymatic assay method. Additionally, cholinergic drug interference with the chemiluminescent assay is minimal. The absence of radioactivity and the reduced cost of the chemiluminescent assay make it an attractive alternative to the radioenzymatic assay.
