[Characteristics of hemostatic disorders in septic shock in children]
Insights
Septic shock in children causes coagulation issues, including hypocoagulation and low platelets. Monitoring these hemostasis changes can help predict patient outcomes.
Area of Science:
- Pediatric intensive care
- Hematology
- Coagulation disorders
Context:
- Septic shock is a critical condition in children.
- Understanding coagulation changes is vital for managing septic shock.
- Previous research has not fully elucidated the dynamic hemostatic alterations in pediatric septic shock.
Purpose:
- To investigate the changes in the coagulation cascade during intensive therapy for pediatric septic shock.
- To correlate hemostatic parameters with disease progression and outcomes.
- To identify predictive markers for septic shock severity and prognosis.
Summary:
- Pediatric septic shock (ages 1-14) involves progressive hypocoagulation, thrombocytopenia, and thrombocytopathy.
- Terminal stages show profound hypocoagulation, reduced antithrombin III and plasminogen, and increased anti-coagulant activity.
- Decreased arterio-venous hemostasis differences indicate severe "shock lung."
Impact:
- Dynamic monitoring of hemostasis can aid in predicting septic shock outcomes in children.
- Findings may inform therapeutic strategies targeting coagulation abnormalities.
- Highlights the complex interplay between sepsis, coagulation, and organ dysfunction.
Abstract:
Changes at different stages of coagulation cascade have been assessed during intensive therapy of septic shock in 40 children aged 1 to 14 years. Progressing septic shock is accompanied by chronometric and structural hypocoagulation with potential hypercoagulation in transfer samples, thrombocytopenia and thrombocytopathy. Terminal stages of septic shock are characterized by profound hypocoagulation without potential hypercoagulation, predominance of antithrombin and antiaggregant blood activity with persistent depletion of antithrombin III and plasminogen. The decrement of arterio-venous difference in hemostasis parameters is typical of marked stages of the shock lung. Dynamic control over hemostasis shifts makes it possible to predict the outcome of septic shock.
