Insights
Pediatric massive transfusion protocols (MTPs) reduce thromboembolic events. Coagulopathy often triggers MTP initiation in critically ill children, warranting further research into MTP benefits and objective initiation factors.
Area of Science:
- Pediatric critical care medicine
- Trauma surgery
- Hematology
Background:
- Pediatric massive blood transfusions are common, but data on massive transfusion protocols (MTPs) are limited.
- This study introduces a pediatric MTP and evaluates its impact on patient outcomes.
- Factors influencing MTP activation were also investigated.
Purpose of the Study:
- To assess the impact of a pediatric massive transfusion protocol (MTP) on morbidity and mortality.
- To identify factors associated with the initiation of a pediatric MTP.
- To compare outcomes between patients managed under an MTP and those receiving transfusions at physician discretion.
Main Methods:
- Prospective cohort study of pediatric patients requiring un-cross-matched blood.
- Data collected from January 1, 2009, to January 1, 2011.
- Comparison of outcomes between MTP and non-MTP groups.
Main Results:
- No significant difference in mortality between MTP and non-MTP groups.
- MTP group had a higher Injury Severity Score (42 vs. 25, p ≤ 0.01).
- Thromboembolic complications were less frequent in the MTP group (p ≤ 0.04).
- Coagulopathy (PTT > 36) was associated with MTP initiation.
Conclusions:
- Massive transfusion protocols (MTPs) may minimize coagulopathy in pediatric hemorrhage.
- MTP use was linked to fewer thromboembolic events.
- Coagulopathy is a key indicator for MTP activation, suggesting further research is needed.
Background:
Pediatric massive blood transfusions occur widely at hospitals across the nation; however, there are limited data on pediatric massive transfusion protocols (MTPs) and their impact. We present a pediatric MTP and examine its impact on morbidity and mortality as well as identify factors that may prompt protocol initiation.
Methods:
Using a prospective cohort, we collected data on all pediatric patients who required un-cross-matched blood from January 1, 2009, through January 1, 2011. This captured patients who received blood products according to the protocol as well as patients who were massively transfused at physician discretion. Outcomes between groups were compared.
Results:
A total of 55 patients received un-cross-matched blood, with 22 patients in the MTP group and 33 patients receiving blood at physician discretion (non-MTP group). Mortality was not significantly different between groups. Injury Severity Score for the MTP group was 42 versus 25 for the non-MTP group (p ≤ 0.01). Thromboembolic complications occurred more exclusively in the non-MTP group (p ≤ 0.04). Coagulopathy, evidenced by partial thromboplastin time (PTT) greater than 36, was associated with initiation of the MTP.
Conclusion:
MTPs have been widely adopted by hospitals to minimize the coagulopathy associated with hemorrhage. Blood transfusion via MTP was associated with fewer thromboembolic events. Coagulopathy was associated with initiation of the MTP. These results support the institution of pediatric MTPs and suggest a need for further research on the protective relationship between MTP and thromboembolic events and on identifying objective factors associated with MTP initiation.
Level Of Evidence:
Therapeutic study, level IV.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
