Insights

This review found that existing data on pediatric airway dimensions are too varied to create clinical guidelines. More comprehensive studies are needed to establish reliable pediatric airway nomograms for equipment selection.

Area of Science:

  • Pediatric Anesthesiology
  • Medical Imaging
  • Anatomy

Background:

  • Accurate pediatric airway dimensions are crucial for selecting appropriate airway management devices.
  • Current data on pediatric airway dimensions are fragmented and lack standardization.

Purpose of the Study:

  • To synthesize existing data on pediatric airway dimensions.
  • To identify gaps in current research for clinical application.

Main Methods:

  • Systematic literature search across multiple databases (PubMed, Scopus, Embase, Web of Science, Prisma, Google Scholar).
  • Analysis of 109 studies published between 1923 and 2018.
  • Inclusion and exclusion criteria applied to select relevant studies.

Main Results:

  • Six measurement methods were identified: anatomical examination, X-ray, CT, MRI, bronchoscopy, and ultrasound.
  • Anatomical and CT studies are considered most reliable; ultrasound shows promise for neonates.
  • Significant heterogeneity in data presentation and study conditions hinders comparability.

Conclusions:

  • Existing studies on pediatric airway dimensions exhibit high heterogeneity, preventing the creation of clinical normograms.
  • There is a critical need for comprehensive studies in large pediatric populations to develop reliable airway dimension nomograms.

Half-life of a Reaction02:42

Half-life of a Reaction

The half-life of a reaction (t1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half of the remaining concentration of the reactant is consumed. For example, during the decomposition of hydrogen peroxide, during the first half-life (from 0.00 hours to 6.00 hours), the concentration of H2O2 decreases from 1.000 M to 0.500 M. During the second half-life (from 6.00 hours to 12.00 hours), the concentration decreases from 0.500 M to...

Characteristics of Life01:23

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

The Angiosperm Life Cycle02:39

The Angiosperm Life Cycle

Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.

Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Support Reactions in Three Dimensions01:27

Support Reactions in Three Dimensions

Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...

Relative Velocity in One Dimension01:10

Relative Velocity in One Dimension

The understanding of the concept of reference frames is essential to discuss relative motion in one or more dimensions. When we say that an object has a certain velocity, we must state the velocity with respect to a given reference frame. In most examples, this reference frame has been Earth. For instance, if a statement reads that a person is sitting in a train moving at 10 m/s east, then it implies that the person on the train is moving relative to the surface of Earth at this velocity,...
