RT Journal Article SR Electronic T1 Endotracheal tolazoline for severe persistent pulmonary hypertension of the newborn. JF British Heart Journal JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 99 OP 100 DO 10.1136/hrt.73.1.99 VO 73 IS 1 A1 Welch, J. C. A1 Bridson, J. M. A1 Gibbs, J. L. YR 1995 UL http://heart.bmj.com/content/73/1/99.abstract AB The condition of a neonate with severe persistent pulmonary hypertension who became severely hypoxic and acidotic despite intensive conventional treatment improved dramatically after endotracheal administration of tolazoline. This logical mode of administration of vasodilator therapy for this condition has not been reported before. It seemed to be life saving in this case and it warrants further clinical trial.
