Insights

Laryngomalacia is the most frequent cause of stridor in infants. This study found it in 66% of children under two, often mild, emphasizing regular monitoring.

Area of Science:

  • Pediatrics
  • Otolaryngology
  • Respiratory Medicine

Background:

  • Laryngomalacia is a common congenital condition causing stridor in infants.
  • It can cause significant parental anxiety.
  • Understanding its prevalence is crucial for clinical management.

Purpose of the Study:

  • To determine the prevalence of laryngomalacia in young children presenting with stridor.
  • To identify the common types and severity of laryngomalacia.
  • To assess associated conditions like sleep-disordered breathing.

Main Methods:

  • A descriptive cross-sectional study was conducted from December 2017 to May 2020.
  • Included children under two years of age presenting with stridor.
  • Utilized clinical examination and video laryngoscopy for diagnosis.

Main Results:

  • Laryngomalacia was diagnosed in 234 out of 430 (66%) children with stridor.
  • The male to female ratio was 1.7:1.
  • Mild laryngomalacia (67.6%) and mixed type (56%) were most common; 39.79% had sleep-disordered breathing.

Conclusions:

  • Laryngomalacia is the predominant cause of stridor in children under two.
  • Most cases are mild and require regular follow-up and weight monitoring.
  • Early diagnosis and management are key to preventing complications.

Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Trachea01:22

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...
