Insights
Warming intravenous (IV) fluids significantly improved comfort in pediatric patients receiving IV fluid boluses in the emergency department. Patients receiving warmed fluids reported less arm coldness compared to those receiving room temperature fluids.
Area of Science:
- Pediatric Emergency Medicine
- Patient Comfort Studies
- Intravenous Fluid Therapy
Background:
- Pediatric patients often report discomfort, specifically coldness, during intravenous (IV) fluid bolus administration.
- This discomfort can negatively impact the patient experience in emergency settings.
Purpose of the Study:
- To evaluate if warmed IV fluids enhance comfort in pediatric patients compared to room temperature IV fluids.
- To assess the impact of fluid temperature on patient-reported comfort and arm temperature during IV infusions.
Main Methods:
- A blinded, randomized controlled trial involving 126 pediatric patients.
- Measurements included overall comfort, arm comfort, and arm temperature at baseline, 15 minutes, and 60 minutes.
- Comparison between warmed IV fluids and room temperature IV fluids.
Main Results:
- Patients receiving warmed IV fluids reported significantly higher comfort levels after 15 minutes (p=0.04).
- Room temperature IV fluids were associated with significantly cooler arm temperatures (p=0.0015).
Conclusions:
- Warming IV fluids is a simple intervention that can improve pediatric patient comfort during IV bolus administration.
- This practice has the potential to enhance the overall patient experience in emergency departments.
Abstract:
A common complaint among pediatric patients receiving an intravenous (IV) fluid bolus is that their arm feels cold and uncomfortable. The purpose of this study is to test if administering warmed IV fluids, as compared to room temperature IV fluids, results in increased comfort among pediatric patients seeking care in an emergency department. A blinded randomized controlled trial was conducted and 126 pediatric patients were enrolled. Each patient's overall comfort, arm comfort, and arm temperature were measured prior to IV fluid administration, 15 minutes after the beginning of the infusion, and at the end of the 60-minute infusion. After the first 15 minutes of IV fluid administration, the patients who received warmed IV fluids reported higher comfort than the patients who received room temperature IV fluids, t(118)=2.04, p=0.04. Additionally, patients who received the room temperature IV fluids reported that their arms felt cooler than patients who received the warmed fluids, t(118)=3.25, p=0.0015. Warming IV fluids has the potential to improve the experience of IV bolus administration for pediatric patients.
