Insights

Fluid bolus therapy (FBT) is common in pediatric emergency departments, primarily for dehydration. This study analyzed FBT use, revealing common indications and effects like reduced heart rate and blood pressure.

Area of Science:

  • Pediatric Emergency Medicine
  • Clinical Pharmacology
  • Critical Care Medicine

Background:

  • Fluid bolus therapy (FBT) is a cornerstone of acute circulatory support in various medical conditions.
  • The epidemiological data regarding FBT use in pediatric emergency departments (EDs) is not well-established.
  • Understanding FBT patterns is crucial for optimizing patient care in pediatric acute settings.

Purpose of the Study:

  • To investigate the indications for fluid bolus therapy in a pediatric emergency department.
  • To analyze the patterns of fluid bolus administration, including volume and fluid type.
  • To assess the short-term physiological effects of fluid bolus therapy in pediatric patients.

Main Methods:

  • A retrospective observational study was conducted using electronic medical record data from a large pediatric ED.
  • Data from all patients receiving intravenous fluid boluses in 2018 were extracted.
  • Demographics, indications, fluid volumes, fluid content, and subsequent vital sign and biochemical changes were analyzed.

Main Results:

  • 1,539 fluid boluses were administered to 1,343 children, representing 1.5% of the ED census.
  • Common indications included vomiting/diarrhea (23%), acute febrile illness (11%), pneumonia, and sepsis (10% each).
  • Fluid bolus therapy was associated with significant reductions in heart rate, mean blood pressure, and venous lactate levels.

Conclusions:

  • Fluid bolus therapy is a frequently utilized intervention in pediatric emergency departments, predominantly for managing dehydration.
  • Observed variability in the indications, dosing strategies, and treatment effects necessitates further research.
  • Further exploration is warranted to refine FBT protocols and enhance outcomes in pediatric emergency care.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

One-Compartment Open Model for IV Bolus Administration: General Considerations

The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Two-Compartment Open Model: IV Bolus Administration

The two-compartment model for intravenous (IV) bolus administration illustrates drug distribution in the body, subdividing it into central and peripheral compartments. This model operates on the concept of two-compartment kinetics. The drug's plasma concentration shows a bi-exponential decline following IV bolus administration, signaling the presence of two disposition processes: distribution and elimination.
The disparity between drug input and the sum of drug transfer rates between...

One-Compartment Open Model for IV Bolus Administration: Estimation of Clearance

Clearance is a key pharmacokinetic parameter that quantifies the volume of body fluid from which a drug is entirely removed within a specific time frame. It is crucial in assessing how a drug is eliminated from the body and has critical clinical applications.
In the one-compartment open model for intravenous (IV) bolus administration, clearance is estimated by dividing the elimination rate by the plasma drug concentration. This equation leverages the elimination rate constant and the apparent...
