Insights

The APLS 2017 guidelines provide a reasonably accurate estimation of paediatric patient weight. However, accuracy decreases with age, and estimations cannot replace actual measurements in acute settings.

Area of Science:

  • Paediatric medicine
  • Clinical assessment
  • Patient safety

Background:

  • Accurate weight measurement is crucial for effective paediatric patient management.
  • Various methods exist for estimating paediatric weight.
  • The Advanced Paediatric Life Support (APLS) 2017 guidelines offer a method for weight estimation.

Purpose of the Study:

  • To evaluate the accuracy of the APLS 2017 estimated weight guidelines in a paediatric population.
  • To compare estimated weights with actual measured weights.
  • To identify potential discrepancies in weight estimation based on age groups.

Main Methods:

  • Retrospective analysis of 100 paediatric patient charts.
  • Calculation of estimated weights using APLS 2017 guidelines.
  • Comparison of estimated versus measured weights using Bland Altman plots.

Main Results:

  • Estimated weight was a good predictor of measured weight.
  • Weight was underestimated by 2.34% to 16.39% of measured weight.
  • Accuracy of estimation decreased with increasing patient age.

Conclusions:

  • The APLS 2017 guidelines offer reasonable accuracy for paediatric weight estimation.
  • Weight underestimation increases with age.
  • Accurate weight measurement remains the gold standard, though estimation is useful when direct measurement is impractical.

Weighted Mean00:57

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Mass and Weight01:19

Mass and Weight

Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Atomic Weight01:25

Atomic Weight

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

Apparent Weight01:09

Apparent Weight

True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...

Cable Subjected to Its Own Weight

Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Polymers: Defining Molecular Weight01:01

Polymers: Defining Molecular Weight

Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight.  So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.
The number average molecular weight (Mn) is the summation of the number...
