Insights

Tetrastarches are the preferred colloid solution for children, offering a better balance of cost and safety compared to older options. They present fewer risks to coagulation and kidney function, making them a safer choice.

Area of Science:

  • Pediatric critical care medicine
  • Pharmacology
  • Fluid resuscitation

Background:

  • Albumin, the traditional colloid osmotic pressure agent, faces challenges due to cost, unproven survival benefits, and viral transmission risks.
  • Synthetic colloids like hydroxyethyl starch and gelatin are increasingly used, each with distinct properties influencing efficacy and safety.
  • Understanding these differences is crucial for optimizing pediatric fluid management.

Purpose of the Study:

  • To review the advantages and disadvantages of various colloid solutions in pediatric patients.
  • To focus on the safety profiles of different colloid preparations.
  • To guide the selection of appropriate fluid therapies in children.

Main Methods:

  • Literature review of studies on colloid solutions in pediatric populations.
  • Comparative analysis of efficacy, safety, and adverse effect profiles.
  • Focus on physicochemical characteristics and clinical outcomes.

Main Results:

  • Dextrans are largely avoided due to adverse effects on coagulation and anaphylaxis risk.
  • Gelatin has limited volume expansion and a high potential for anaphylactoid reactions; albumin has minimal hemostatic impact.
  • Tetrastarches demonstrate improved safety regarding coagulation and renal function compared to older hydroxyethyl starches and are approved for pediatric use.
  • Plasma-adapted solutions for tetrastarches enhance safety for coagulation and acid-base balance.

Conclusions:

  • Tetrastarches represent the optimal current choice for pediatric fluid management, balancing cost-effectiveness and safety.
  • They are particularly suitable for children with normal pre-existing renal and coagulation function.
  • Further research may refine the use of synthetic colloids in specific pediatric scenarios.

Colloids and Suspensions

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Coagulation01:06

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
Colloidal precipitates01:09

Colloidal precipitates

The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

The Colloidal State

The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called the...

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...
