Current technique of intraperitoneal transfusion: do not throw away the renografin

The original description of intraperitoneal transfusion calls for contrast-dye infusion and X-ray confirmation of placement of the needle free in the peritoneal cavity. Ultrasound methods, using air or saline as contrast media, have been described to replace the X-rays. This report illustrates at least one way in which the ultrasound findings at intraperitoneal transfusion may be illusory, allowing misplaced transfusion into the fetal colon. In specific instances, use of radiopaque dye at intraperitoneal transfusion may still be helpful.
