Transfusions Suggested For Neonatal Disorders
Preliminary studies suggest that exchange transfusions with fresh adult blood may help sustain infants with respiratory distress syndrome until spontaneous disappearance of the hyaline membranes and associated atelectasis. Two infants with the syndrome are believed to have benefitted from the treatment.
Investigators from the University of Pennsylvania School of Medicine in Philadelphia suggested the therapy in a paper presented to the Society of University Surgeons meeting in Pittsburgh.
They said that respiratory distress syndrome (RDS) is one of three conditions in which the oxyhemoglobin dissociation curve shifts maladaptively to the left because of a drop in the level of 2,3 diphosphoglycerate (DPG) in the red cell. The other two conditions occur in patients with septic shock and in patients who have had massive bood transfusions.
Speaking for the multidisciplinary team, Leonard D. Miller, MD, explained that as DPG levels fall, there is an increase
