Brief Summary

Critically ill children supported by extracorporeal membrane oxygenation (ECMO) receive large volumes of prophylactic platelet transfusions to prevent bleeding. However, mounting evidence has demonstrated significant morbidity and mortality associated with these transfusions. The ECmo hemoSTAtic Transfusions In Children (ECSTATIC) pilot trial will test two different platelet transfusion strategies, based on two different platelet counts thresholds, one high (higher platelet transfusion strategy) and one low (lower platelet transfusion strategy). The pilot will gather the necessary information to perform a full trial which will provide a better understanding of how to transfuse platelets to children supported by ECMO and reduce the associated morbidity.

Outcome Measures

Primary Outcomes (2)

  • Total Platelet Transfusion Dose

    The total dose (in mL/kg/day) will be computed by the research team, by dividing the total platelet transfusion volume by the patient's weight at admission and the number of days of intervention.

    up to day 21

  • Pre-transfusion Platelet Count

    Pre-transfusion platelet count, during intervention

    During intervention

Secondary Outcomes (8)

  • Feasibility Assessed by the Screening Rate

    At screening

  • Feasibility Assessed by the Inclusion Rate

    At screening

  • Feasibility Assessed by the Number of Informed Consents Signed in the First 24 Hours Post Cannulation.

    At screening

  • Compliance With Transfusion Thresholds

    up to Day 21

  • Participants With at Least One Temporary Suspension

    up to Day 21

  • +3 more secondary outcomes

Study Arms (2)

Higher platelet transfusion strategy

ACTIVE COMPARATOR

Participants randomized to this arm will be transfused if the platelet count is \< 90 x 10e9 cells/L.

Biological: Platelet Transfusion

Lower platelet transfusion strategy

EXPERIMENTAL

Participants randomized to this arm will be transfused if the platelet count is \< 50 x 10e9 cells/L.

Biological: Platelet Transfusion

Interventions

Participants will be transfused according to the assigned threshold for each group, with a transfusion dose of 10 mL/kg, up to one adult unit.

Eligibility Criteria

AgeUp to 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Critically ill children (0 to \<18 years of age)
  • Admitted to a participating pediatric, neonatal, or cardiac intensive care unite (PICU/NICU/CICU)
  • On extracorporeal Membrane Oxygenation (ECMO)
  • Who have either no bleeding or minimal bleeding, within 24 hours of cannulation. Minimal bleeding is defined as:
  • streaks of blood in endotracheal tube or during suctioning only
  • streaks of blood in nasogastric tube
  • macroscopic hematuria
  • subcutaneous bleeding (including hematoma and petechiae) \< 5 cm in diameter
  • quantifiable bleeding \< 1mL/kg/hr (e.g., chest tube)
  • bloody dressings required to be changed no more often than each 6hr, or weighing no more than 1mL/kg/hr if weighed, due to slow saturation

You may not qualify if:

  • Post-conception age \< 37 weeks at time of screening
  • Underlying oncologic diagnosis (defined as receipt of chemotherapy or radiation in the last six months) or recipient of bone marrow transplant in the last year
  • Congenital bleeding disorder
  • Pregnant or admitted post-partum
  • Decision to withdraw or withhold some critical care or interventions
  • Known objection to blood transfusions
  • On ECMO for \> 24 hours at time of enrollment

Data Sharing

IPD Sharing
Will share

The proposed research will include data from 50 critically ill subjects who are on extracorporeal life support (ECMO) enrolled at ten participating sites. The final dataset will include demographic and medical information, as well as laboratory data. After the investigators' proposed research is complete, each participating site will destroy the key linking this data to protected health information (PHI). Thus, the data will then be completely de-identified. However, the investigators believe that there remains the possibility of deductive disclosure of subjects with unusual characteristics, considering the variety of rare conditions leading to ECMO.

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR
Time Frame
The investigators reserve the right to embargo the data for as long as two years after completion of the project (i.e. fall 2027) in order to allow the investigators' research team to publish additional observations from the data.
Access Criteria
The investigators will make the data and associated documentation available to users only under a data-sharing agreement that provides for: (1) a commitment to using the data only for research purposes and not to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) a commitment to destroying the data after analyses are completed.
