Clinical Trial Summary

The objectives of this multicenter pragmatic clinical trial are to compare the effectiveness and relative safety of balanced fluid resuscitation versus 0.9% "normal" saline in children with septic shock, including whether balanced fluid resuscitation can reduce progression of kidney injury.

Description:

Approximately 5,000 children die from septic shock each year in the United States (US); thousands more die worldwide. Most children admitted with sepsis receive initial resuscitation in an emergency department (ED), where septic shock remains one of the most critical of illnesses treated by ED clinicians. Sepsis is also the most expensive hospital condition in the US, and the most common cause of pediatric multiple organ dysfunction syndrome (MODS). While all crystalloid fluids help to reverse shock, the most effective and safest type of crystalloid fluid resuscitation is unknown.

Crystalloid fluids can be categorized as non-buffered (most commonly 0.9% normal saline [NS]) or buffered/balanced fluids (BF). In the US, the most common BF is lactated Ringer's (LR), but other example include PlasmaLyte. NS and BF are inexpensive, stable at room temperature, and nearly universally available with identical storage volumes and dosing strategies. Notably, both are also of proven clinical benefit in septic shock and have extensive clinical experience for use in fluid resuscitation of critically ill patients. However, despite data suggesting that BF resuscitation may have superior efficacy and safety, NS remains the most commonly used fluid largely based on historical precedent.

To definitively test the comparative effectiveness of NS and BF, a well-powered randomized controlled trial (RCT) is necessary. A large pragmatic randomized trial embedded within everyday clinical practice provides a cost-efficient and generalizable approach to inform clinicians about best comparative effectiveness of common therapies. Data from a prior single-center feasibility study demonstrated that a pragmatic randomized clinical trial of NS versus BF for children with septic shock presenting to an emergency department is feasible and can be successfully carried out by embedding simple study procedures within routine clinical practice. This multi-center study that will now test for differential clinical effects, as part of a definitive comparative effectiveness trial, of NS versus BF for crystalloid resuscitation of pediatric septic shock.

This multicenter phase trial will include enrollment and study procedures across 30+ US and international sites to compare the effectiveness and relative safety of NS versus BF (LR and PlasmaLyte) for crystalloid resuscitation of children with septic shock. The primary endpoint is major adverse kidney events within 30 days along with other secondary clinical, safety, and kidney biomarker endpoints.

Intervention

Drug:
• Lactated Ringer
LR is a sterile, nonpyrogenic "balanced" solution used for fluid and electrolyte replenishment via intravenous or intraosseous administration. Each 100 mL of LR contains 600 mg sodium chloride (NaCl), 310 mg of sodium lactate (C3H5NaO3), 30 mg of potassium chloride (KCl), and 20 mg of calcium chloride (CaCl2 · 2H20) with an approximate potential of hydrogen (pH) of 6.5 (6.0 to 7.5).
• Normal Saline
Normal saline solution is an "unbalanced" crystalloid solution containing 154 mEq/L of sodium and 154 milliequivalent (mEq/L) of chloride.
• Plasma-lyte
PL is a sterile, nonpyrogenic isotonic solution in a single dose container for intravenous administration. Each 100 mL contains 526 mg of Sodium Chloride, USP (NaCl); 502 mg of Sodium Gluconate (C6H11NaO7); 368 mg of Sodium Acetate Trihydrate, USP (C2H3NaO2•3H2O); 37 mg of Potassium Chloride, USP (KCl); and 30 mg of Magnesium Chloride, USP (MgCl2•6H2O). It contains no antimicrobial agents. The pH is adjusted with sodium hydroxide. The pH is 7.4 (6.5 to 8.0).
