Total lung lavage for pulmonary alveolar proteinosis in an infant without the use of cardiopulmonary bypass.
Pulmonary alveolar proteinosis is a rare disease that usually affects the adult patient, but is now being recognized as a possible cause of neonatal respiratory distress. In the adult patient, whole lung lavage, as described by Ramirez-R in 1965, is considered the most effective therapy for management of this condition. The lavage can be accomplished safely and with relative ease by using a Carlens or Robertshaw tube to isolate and lavage one lung while ventilating the other. The unavailability of a small double-lumen tube makes this procedure impossible in the pediatric age group. Therefore, whole lung lavage has been possible in only a few children in the past with the help of cardiopulmonary bypass to allow simultaneous oxygenation during the pulmonary lavage. Due to the hazards and technical difficulties of cardiopulmonary bypass, total pulmonary lavage can not be considered a practical option in the very small infant. A 15-week-old infant is reported, weighing 2 kg with a diagnosis of pulmonary alveolar proteinosis, who underwent total pulmonary lavage safely on three different occasions without employing cardiopulmonary bypass. A double-lumen Swan-Ganz catheter, introduced transbronchoscopically through the side-arm of a rigid, 3.5-mm Storz bronchoscope was used to isolate and lavage one lung while ventilation to the other lung was maintained through the bronchoscope. A Nellcor oximeter, utilized for transcutaneous monitoring, revealed satisfactory oxygen saturation during the entire pulmonary lavage. The transbronchoscopic lavage was monitored under direct vision with a video monitor, ensuring correct position of the bronchoscope and the catheter at all times.(ABSTRACT TRUNCATED AT 250 WORDS)
