The centrineurogenic etiology of the respiratory distress syndrome: protection by unilateral chronic pulmonary denervation in hemorrhagic shock.

Anemic beagles were subjected to 40 mm Hg hemorrhagic shock for 2 hours, which uniformly induced the pulmonary lesions of the "respiratory distress syndrome" (RDS) bilaterally in all six controls. For six subjects with complete denervation of the left lung 2 months previously, the shock regimen induced the lesions in the normally innervated right lungs; all reimplanted, denervated left lungs remained anatomically intact. This is presented as additional evidence for a centrineurogenic etiology for RDS.
