Insights

Bolus fluid therapy for severe infections in children significantly increased mortality in a large African trial. This challenges standard sepsis treatment protocols, emphasizing closer fluid monitoring in pediatric care.

Area of Science:

  • Pediatric critical care medicine
  • Infectious diseases
  • Global health

Background:

  • Bolus fluid administration is a common intervention for children with severe infections and signs of shock.
  • The Fluid Expansion as Supportive Therapy (FEAST) trial investigated fluid resuscitation strategies in African children.

Purpose of the Study:

  • To evaluate the impact of bolus fluid therapy versus no bolus on mortality in children with severe infections in resource-limited settings.

Main Methods:

  • A high-quality randomized controlled trial involving 3170 children in Africa.
  • Primary outcome was 48-hour mortality.

Main Results:

  • Bolus fluid therapy was associated with significantly higher mortality compared to no bolus administration.
  • Findings challenge the universal application of bolus fluid regimes for sepsis and compensated shock in pediatric advanced life support.

Conclusions:

  • Intravenous fluid management, particularly bolus administration, requires critical re-evaluation in pediatric severe infections in resource-limited settings.
  • Closer monitoring of fluid status is essential, and the practice of routine boluses for suspected sepsis needs careful consideration.

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, half-life,...

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...

One-Compartment Open Model for IV Bolus Administration: Estimation of Elimination Rate Constant, Half-Life and Volume of Distribution

The one-compartment open model is a simplified approach used in pharmacokinetics to understand the distribution and elimination of a drug administered through an intravenous bolus. This model assumes rapid drug dispersal throughout the body and elimination using a first-order process. Key pharmacokinetic parameters, such as the elimination rate constant (k), half-life (t1/2), and the apparent volume of distribution (Vd), can be estimated from this model. The elimination rate is calculated from...

Nonlinear Pharmacokinetics: Drug Elimination for IV Bolus Injection

In pharmacokinetics, the elimination rate of a drug following a capacity-limited model is primarily controlled by two parameters: Vmax and KM. These parameters are crucial in how the drug behaves inside the body after administration.
Following the administration of a single intravenous (IV) bolus injection, we can determine the concentration of the drug in the plasma at any given time. This calculation is achieved using a specific equation that integrates the values of Vmax and KM.
