Insights

Accurate fluid balance records are crucial for critically ill children. UK Paediatric Intensive Care Units (PICUs) show significant variation in recording fluid intake, often omitting essential flushes, risking undetected fluid creep.

Area of Science:

  • Pediatrics
  • Critical Care Medicine
  • Nursing Research

Background:

  • Accurate fluid balance monitoring is vital for critically ill children, particularly neonates and infants.
  • Current fluid balance recording practices in UK Paediatric Intensive Care Units (PICUs) are not standardized.
  • Potential for unrecognised fluid accumulation ('fluid creep') exists due to inconsistent intake recording.

Purpose of the Study:

  • To assess the variability in fluid intake recording by nurses across UK PICUs.
  • To identify specific fluid sources commonly omitted from intake records.
  • To inform educational strategies for improving fluid balance accuracy in pediatric critical care.

Main Methods:

  • A cross-sectional electronic survey was distributed to nurse educators in all UK PICUs.
  • The survey collected data on which fluid sources were included in patient intake records.
  • Responses from 30 nurse educators representing 23 PICUs were analyzed.

Main Results:

  • Substantial variation in fluid intake recording practices was identified across UK PICUs.
  • Many units excluded flushes administered after intravenous or enteral medications.
  • Few units recorded flushes given after blood sampling or blood gas analysis; charts often only captured infusions and drugs.

Conclusions:

  • Inconsistent recording of fluid intake, particularly flushes, is prevalent in UK PICUs.
  • This variability poses a risk of unrecognised positive fluid balance ('fluid creep') in critically ill children.
  • Standardized education and clear guidelines are needed to improve the accuracy of fluid balance documentation before initiating conservative fluid management trials.

Disorder of Water Balance01:29

Disorder of Water Balance

Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...
Drug Dosing: Infants and Children01:29

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, compared...

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions (Na+) and chloride...
Fluid Movement Between Compartments01:18

Fluid Movement Between Compartments

The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...
