Computed Tomography01:10

Computed Tomography

9.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation I: X-ray and CT

1.4K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Cardiopulmonary Resuscitation II: ACLS Airway Management

845
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

714
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Summary
This summary is machine-generated.

The pediatric airway in infants is elliptical, not funnel-shaped. The subglottic region and cricoid ring show distinct anteroposterior widening and transverse narrowing in neonates and infants.

Area of Science:

  • Pediatric radiology
  • Airway anatomy
  • Neonatal imaging

Background:

  • Challenging the traditional view of a funnel-shaped pediatric airway.
  • Highlighting the elliptical nature of the pediatric airway with the subglottis as the narrowest point.
  • Addressing the lack of separate studies on airway shape in neonates and infants.

Purpose of the Study:

  • To define the upper airway shape in neonates and infants.
  • To determine differences in airway shape between infants and older children.

Main Methods:

  • Analysis of 40 computed tomographic (CT) scans from children aged 0-12 months.
  • Measurements of transverse and anteroposterior diameters at subglottic and cricoid levels.
  • CT scans obtained during natural sleep or sedation with spontaneous ventilation.

Main Results:

  • Mean age of subjects was 5.9 months.
  • Airway dimensions at the subglottic region: transverse 5.3 mm, anteroposterior 7.2 mm.
  • Airway dimensions at the cricoid ring: transverse 6.1 mm, anteroposterior 6.7 mm, showing transverse widening and anteroposterior narrowing from subglottis to cricoid.

Conclusions:

  • The airway in neonates and infants is elliptical between the subglottic area and cricoid.
  • The cricoid ring in infants is not round, unlike in older children.
  • Infant airways are wider anteroposteriorly and narrower transversely from the subglottis to the cricoid.
