About

This study is designed to help decide how much intravenous (IV) fluid should be given to pediatric trauma patients. No standard currently exists for managing fluids in critically ill pediatric trauma patients, and many fluid strategies are now in practice. For decades, trauma patients got high volumes of IV fluid. Recent studies in adults show that patients actually do better by giving less fluid. The investigators do not know if this is true in children and this study is designed to answer that question and provide guidelines for IV fluid management in children after trauma.

Full description

Aggressive fluid resuscitation has been the cornerstone of early post-operative and trauma management for decades. However, recent prospective adult studies have challenged this practice, linking high volume crystalloid resuscitation to increased mortality, cardiopulmonary, gastrointestinal and hematologic complications. A retrospective study the investigators recently performed at their quaternary-care children's hospital echoed these results. High quality prospective data is necessary to determine best practice guidelines in our pediatric surgery and trauma patients.

Currently, no standard exists to guide management of crystalloid fluid administration in trauma patients. Both liberal and restricted strategies are in use, dependent on physician discretion. The investigators propose the first randomized controlled trial (RCT) comparing a liberal to a restricted fluid management strategy in critically ill pediatric trauma patients. The objective of this comparative effectiveness study is to conduct a multicenter (around 10 sites) randomized controlled trial (RCT) to determine whether liberal or restricted fluid administration leads to better outcomes in these patients.

Liberal IV Fluid

Active Comparator group

Description:

Maintenance fluid rate calculated by 4-2-1 formula for patients <110kg: 4 mL/kg for first 0-10kg + 2 mL/kg for 11-20kg + 1 mL/kg for each kg >20kg Patients >110kg maintenance 150 mL/hr Bolus Criteria: change in 1 of: >20% decrease in systolic blood pressure 50th percentile for age and sex, >20% increase in heart rate over 50th percentile for age, base excess > -5mmol/L, blood lactate >2mmol/L, AND urine output (UO) <1 mL/kg/hr if <50kg or <50 mL/hr if >50kg If criteria met: bolus 20 mL/kg if <50kg or 1 L if ≥50 kg For transfusion: give 10 mL/kg packed red blood cells, platelets, or fresh frozen plasma up to 250 mL. If >25kg give 250 mL. Diuresis- after minimum 24hrs: if UO <2 mL/kg/hr (or <100 mL/hr if >50 kg) continue maintenance rate and bolus per initial phase. If UO >2 mL/kg/hr (or >100 mL/hr if >50kg), and lactate, systolic blood pressure, heart rate, creatinine are normal then lower IV fluid rate to ½ maintenance rate and then to "keep vein open" once on regular feeds

Other: Platelets volume

Other: Balanced crystalloid solution volume administration

Other: Plasma volume

Other: Packed Erythrocytes Units, Blood Product Unit volume

Restricted IV Fluid

Experimental group

Description:

Maintenance fluid rate calculated by 70% of 4-2-1 formula if <110 kg: 4 mL/kg for first 0-10 kg, + 2 mL/kg for 11-20 kg, + 1 mL/kg for every kg >20 kg Patients >110 kg: maintenance is 105 mL/hr If same bolus criteria met: 10 mL/kg for patients <50kg, or 500 mL if ≥50 kg If meet transfusion criteria: transfuse 10 mL/kg with packed red blood cells, platelets, or fresh frozen plasma by weight up to 250 mL. Patients >25 kg get 250 mL per transfusion Diuresis (after minimum 24 hrs): if UO <1 mL/kg/hr (or <50 mL/hr if >50 kg) then continue IV fluids at maintenance rate and bolus as needed. If UO 1-2 mL/kg/hr (or 50-100 mL/hr if >50 kg) then decrease IV rate to ½ maintenance rate. If UO >2 mL/kg/hr (or >100 mL/hr if >50 kg), and Lactate, systolic blood pressure, heart rate, creatinine normal then reduce to "keep vein open" and consider Furosemide for goal UO >2-4 mL/kg/hr (100-200 mL/hr if >50 kg) until euvolemic
