Hemostatic changes in neonates with anoxia and sepsis

Area of Science:

• Neonatal Medicine
• Hematology
• Perinatology

Background:

• Birth anoxia and sepsis are critical conditions in neonates.
• Hemostatic system alterations can occur in critically ill newborns.
• Disseminated intravascular coagulation (DIC) is a potential complication.

Purpose of the Study:

• To investigate hemostatic profiles in neonates with birth anoxia and sepsis.
• To assess the impact of condition severity on coagulation.
• To evaluate the efficacy of Vitamin K in anoxic neonates.

Main Methods:

• Examined hemostatic profiles (PT, TT, KCCT, fibrinogen, FDP, platelets) in 153 neonates with birth anoxia and 86 with sepsis.
• Compared coagulation parameters based on anoxia severity (severe vs. moderate).
• Assessed changes after Vitamin K administration in anoxic neonates.

Main Results:

• Significant hemostatic alterations were observed in neonates with severe anoxia and sepsis.
• Neonates with moderate anoxia showed minimal or no hemostatic changes.
• Vitamin K administration did not improve the hemostatic profile in anoxic neonates after 48-72 hours.
• Despite coagulation changes, clinical bleeding was infrequent.

Conclusions:

• Hemostatic alterations in severe anoxia and sepsis are likely due to incipient DIC.
• Neonatal hemostasis appears well-balanced, even with significant coagulation derangements.
• Vitamin K is ineffective in correcting these specific hemostatic abnormalities.
