Postoperative fetal circulation: POFC

T C Martin, R J Bower, M J Bell

    Journal of Pediatric Surgery

    Summary
    This summary is machine-generated.

    Persistent fetal circulation (PFC) can occur late after neonatal surgery. This condition, characterized by right-to-left shunting, requires prompt diagnosis and management in postoperative infants.

    Area of Science:

    • Neonatal cardiorespiratory disorders
    • Pediatric surgery
    • Critical care medicine

    Background:

    • Persistent fetal circulation (PFC) involves active pulmonary vasoconstriction and shunting of venous blood.
    • This phenomenon can complicate neonatal cardiorespiratory conditions.

    Observation:

    • Two neonates developed late-onset PFC after major intra-abdominal surgery.
    • One patient had an omphalocele repair, the other a gastric perforation repair.
    • Both experienced severe hypoxia and right-to-left shunting postoperatively.

    Findings:

    • Postoperative fetal circulation (POFC) was diagnosed via contrast echocardiography.
    • Both patients responded to hyperventilation and/or tolazoline therapy.
    • Contrast echocardiography proved a valuable noninvasive diagnostic tool.

    Implications:

    • POFC should be considered in postoperative neonates with unexplained hypoxia.
    • Early diagnosis and intervention are crucial for favorable outcomes.
    • This condition highlights the importance of vigilant monitoring in surgical neonates.
