Coagulation and the surgical neonate.

Area of Science:

• Anesthesiology
• Pediatric Hematology
• Neonatal Intensive Care

Background:

• Neonatal coagulopathy and thrombosis present unique challenges in perioperative management, differing significantly from adult or older pediatric populations.
• Severe bleeding is primarily associated with neonatal heart surgery and sepsis, while thrombosis often relates to vascular access devices or shunts.

Purpose of the Study:

• To review the distinct features of the neonatal coagulation system compared to older patients.
• To guide perioperative practice by highlighting differences in coagulation and their implications for neonatal care.

Main Methods:

• Literature review focusing on neonatal coagulation physiology and perioperative complications.
• Analysis of differences between neonatal and adult coagulation systems.
• Discussion of implications for managing bleeding, thrombosis, and coagulopathy in neonates.

Main Results:

• Neonatal coagulation differs substantially from that of older individuals, necessitating adapted therapeutic approaches.
• Severe bleeding risks are highest during neonatal heart surgery and in cases of sepsis.
• Thrombosis is frequently linked to the presence of indwelling vascular access or surgical shunts.

Conclusions:

• Therapies for coagulation disorders in adults are not directly transferable to neonates and require adaptation.
• Understanding neonatal-specific coagulation mechanisms is essential for improving perioperative outcomes.
• Tailored management strategies are critical for addressing bleeding and thrombosis in neonates undergoing surgery or with sepsis.
