Drs. Fong and Margolis comment as follows:
This is in regards to the letter to the Editor by Dr. J. M. Bowman, commenting on our paper, "Intra-uterine Transfusions: Fetal Outcome and Complications."1
The initial localization of the needle in the fetal abdomen was performed by the instillation of carbon dioxide but was subsequently checked by injection of radio-opaque material as described in a previous report.2
Dr. Bowman's point is well taken in regards to the use of reduced volumes of blood for improved survival after IUT.
