Insights

The Luskin and Owens (LO) formula accurately estimates paediatric weights, significantly outperforming the APLS formula in a large Irish study. This improved accuracy is crucial for effective resuscitation in children.

Area of Science:

  • Paediatric emergency medicine
  • Clinical pharmacology
  • Biostatistics

Background:

  • Accurate weight estimation is critical for paediatric resuscitation and management.
  • The APLS formula ('2×(age+4)') is widely used but its accuracy is questioned due to rising childhood obesity.
  • The Luscombe and Owens (LO) formula ('(3×age)+7') is a proposed alternative for weight estimation.

Purpose of the Study:

  • To collect weight and age data for children (1-15 years) at Cork University Hospital (CUH).
  • To compare the diagnostic accuracy of the APLS and LO weight estimation formulae in this population.

Main Methods:

  • Retrospective data collection from patient charts at CUH, Ireland's sole level one trauma centre.
  • Inclusion of 3155 children aged 1-15 years (1344 girls, 1811 boys).
  • Analysis of weight underestimation by both the APLS and LO formulae.

Main Results:

  • The APLS formula underestimated children's weights by a mean of 20.3% (95% CI 19.7%–20.9%).
  • The LO formula demonstrated a significantly lower mean underestimation of 4.0% (95% CI 3.3%–4.6%).

Conclusions:

  • The LO formula is a more accurate age-based weight estimation tool for Irish children aged 1-15 years.
  • This study validates the LO formula as a simple, safe, and superior alternative to the APLS formula in a paediatric emergency setting.
  • The findings support the adoption of the LO formula for improved clinical decision-making in paediatric resuscitation.

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Internal Forces and Center of Gravity

Internal forces and the center of gravity are fundamental concepts in mechanics, playing a crucial role in understanding the behavior and stability of structures and objects under various conditions. A comprehensive understanding of these principles is essential for engineers, architects, and designers to create safe and efficient systems.
Internal forces are generated within a body due to the interaction between its particles. These forces can be categorized into tension, compression, 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.

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

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...
