Pragmatic Pediatric Trial of Balanced Versus Normal Saline Fluid in Sepsis

Children's Hospital of Philadelphia8,800 enrolled

Overview

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.

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.

Interventions

Lactated RingerDRUG

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 SalineDRUG

Normal saline solution is an "unbalanced" crystalloid solution containing 154 mEq/L of sodium and 154 milliequivalent (mEq/L) of chloride.

Plasma-lyteDRUG

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).

Medical Language ↔ Plain English

Inclusion Criteria: 1. Males or females age \>2 months to \<18 years 2. Clinician concern for septic shock, operationalized as: 1. a "positive" ED sepsis alert confirmed by a physician OR 2. physician decision to treat for septic shock OR 3. a physician diagnosis of septic shock requiring parenteral antibiotics and fluid resuscitation 3. Administration of at least one IV/Intraosseous (IO) fluid bolus for resuscitation and additional fluid deemed likely to be necessary to treat poor perfusion, or clinician judgment that \>1 fluid bolus is highly likely to be required. Poor perfusion is defined as physician's judgement of hypotension or abnormal (either "flash" or "prolonged") capillary refill. 4. Receipt of ≤40 mL/kg IV/IO total crystalloid fluid prior to randomization 5. Parental/guardian permission (informed consent) if time permits; otherwise, Exception from informed consent (EFIC) criteria met Exclusion Criteria: 1. Treating physician judges that patient's condition deems it unsafe to administer either NS or BF (since patients will be equally likely to receive NS or BF at time of study enrollment), including: 1. Clinical suspicion for impending brain herniation 2. Known hyperkalemia, defined as non-hemolyzed whole blood or plasma/serum potassium \> 6 mEq/L, based on data available at or before patient meets criteria for study enrollment 3. Known hypercalcemia, defined as plasma/serum total calcium \>12 mg/dL or whole blood ionized calcium \>1.35 mmol/L, based on data available at or before patient meets criteria for study enrollment 4. Known acute fulminant hepatic failure, defined as plasma/serum alanine aminotransferase (ALT) \>10,000 U/L or total bilirubin \>12.0 mg/dL, based on data available at or before patient meets criteria for study enrollment 5. Known history of severe hepatic impairment, defined as cirrhosis, "liver failure", or awaiting transplant 6. Known history of severe renal impairment, defined as peritoneal dialysis or hemodialysis 7. Known metabolic/mitochondrial disorder, inborn error of metabolism, or primary mineralocorticoid deficiency as reported by participant, legally authorized representative (LAR) or accompanying caregiver, or as listed in the medical record 8. Other concern for which the treating clinician deems it unsafe to administer either NS or LR 2. Known pregnancy determined by routine history disclosed by patient and/or accompanying acquaintance. 3. Known prisoner 4. Known allergy to a crystalloid fluid 5. Indication of declined consent to participate based on presence of an opt-out bracelet with appropriate messaging embossed into the bracelet, the presence of the patient's name on an opt-out list that will be kept up-to-date and checked prior to randomization, or verbal "opt-out" prior to enrollment.
