Frequently Asked Questions

How will the study work?

If a child is enrolled in PRoMPT BOLUS, they will be randomly assigned during their ED visit (like the flip of a coin) to receive either NS or LR IV fluids as part of their sepsis treatment.  They will then receive study fluid as their treatment fluid during the remained of their ED visit and for up to 48 hours of their hospitalization if they are admitted to the hospital.  The child’s doctors will determine when to give fluid and how much fluid to give, just as they would for a child not in the study.

What is the difference between NS and LR?

Both NS and LR are electrolyte solutions- forms of salt water- that are safe, FDA-approved, and commonly used to treat sepsis.  At CHOP, about half of children admitted to the Pediatric Intensive Care Unit (PICU) are treated with NS and half are treated with LR.  The chemical composition of NS and LR are slightly different in that NS has only sodium and chloride, while LR contains less sodium, less chloride, and also has small amounts of other electrolytes like calcium and potassium

Why is this study being done?

Although both NS and LR are safe, FDA-approved, and commonly used to treat sepsis, nobody knows for sure whether one fluid is more effective and safer to treat sepsis than the other.  Several prior studies have suggested that LR may be superior to NS, but a clear determination cannot be made without a large clinical trial.  In pediatrics, NS is generally the preferred fluid used to treat sepsis but LR is also commonly used, especially for children admitted to the CHOP Pediatric Intensive Care Unit (PICU).  However, nobody yet knows for sure which fluid is safer or more effective.

Will the study affect any other part of a child’s treatment for sepsis?

NO. Decisions about when and how much fluid a child receives, as well as any other medications that they might need will not be affected by the study.  These will be decided by the treatment team as they normally would for any child with possible sepsis.

What if my child is enrolled in the study and I change my mind about wanting them to participate?

A subject is free to withdraw from study participation at any time by contacting the study team either in person or by email:

What if I have questions or concerns about EFIC?

We encourage you to contact us with any questions/concerns, complete an online survey, and/or to participate in one of our focus groups so that we may work together to share information about patient enrollment through EFIC and learn from each other.

What if I do not want my child to participate in the study at all?

If you would like to opt your child out of the study so that they would not be included if they developed possible sepsis, please fill out this form. Any patient who has opted out will be mailed a bracelet that they must wear for the duration of the study so that they will not be enrolled even if they present to the CHOP Emergency Department with possible sepsis.
