Patent Ductus Arteriosis (PDA) is a congenital heart defect resulting from a blood vessel, called the ductus arteriosus, that remains open after birth.
A report on a patient with subclinical patent ductus arteriosis by Reddy and colleagues provides a useful update on the investigations of this condition.
The studies focused on early applications of the technology in the neonatal intensive care unit (NICU), including investigations of how cerebral/somatic blood oxygen data may correlate to severe conditions that are traditionally difficult to diagnose such as necrotizing enterocolitis and patent ductus arteriosis as well as to the need for blood transfusions.
Since many congenital cardiac defects involve mixing of oxygenated and de-oxygenated blood at the site of the ductus arteriosis, there can be considerable differences in oxygenation of arterial blood sampled pre-ductally versus post-ductally.
