Insights
A 1:1 ratio of packed red blood cells to fresh frozen plasma (PRBC:FFP) best supports survival in pediatric trauma massive transfusion. Higher ratios increase mortality risk, indicating a need for more plasma products.
Area of Science:
- Pediatric Trauma Care
- Resuscitation Science
- Hemorrhagic Shock Management
Background:
- Massive transfusion protocols (MTPs) are critical in pediatric trauma care.
- Optimal blood component ratios for MTPs in children remain unclear.
- Understanding survival benefits is essential for improving outcomes.
Purpose of the Study:
- To investigate the association between packed red blood cell to fresh frozen plasma (PRBC:FFP) ratios and survival in pediatric trauma patients.
- To determine the optimal PRBC:FFP ratio for massive transfusions in severely injured children.
Main Methods:
- Retrospective review of data from five Level I Pediatric Trauma Centers (2007-2013).
- Inclusion criteria: children (≤18 years) receiving MTP or >20 mL/kg PRBCs.
- Analysis of patient demographics, injury severity, and transfusion ratios.
Main Results:
- 110 pediatric trauma patients met inclusion criteria; 73% survived.
- Survival rates were not significantly different based on initial hemoglobin, gender, or age.
- Increased mortality was associated with PRBC:FFP ratios higher than 1:1 (OR 3.08).
Conclusions:
- A 1:1 PRBC:FFP ratio is associated with the highest survival in pediatric trauma patients undergoing massive transfusion.
- Ratios of 2:1 or higher significantly increase the risk of death.
- Findings support increased use of plasma products in pediatric massive transfusion protocols.
Background/Purpose:
Massive transfusion protocols (MTPs) are considered valuable in pediatric trauma. Important questions regarding the survival benefit and optimal blood component ratio remain unknown.
Methods:
The study time frame was January 2007 through December 2013 five Level I Pediatric Trauma Centers reviewed all trauma activations involving children ≤18 years of age. Included were patients who either had the institutional MTP or received >20 mL/kg or > 2 units packed red blood cells (PRBCs).
Results:
110/202 qualified for inclusion. Median age was 5.9 years (3.0-11.4). 73% survived to discharge; median hospitalization was 10 (3.1-22.8) days. Survival did not vary by arrival hemoglobin (Hgb), gender or age. Partial prothrombin time (PTT), INR, GCS and injury severity score (ISS) significantly differed for nonsurvivors (all p < 0.05). Logistic regression found increased mortality (OR 3.08 (1.10-8.57), 95% CI; p = 0.031) per unit increase over a 1:1 ratio of pRBC:FFP.
Conclusion:
In pediatric trauma pRBC:FFP ratio of 1:1 was associated with the highest survival of severely injured children receiving massive transfusion. Ratios 2:1 or ≥3:1 were associated with significantly increased risk of death. These data support a higher proportion of plasma products for pediatric trauma patients requiring massive transfusion.
