Insights

Children with sleep disordered breathing often have central apnoea and bradypnoea. Posterior fossa decompression for Arnold Chiari type 1 malformation can normalize their sleep breathing patterns.

Area of Science:

  • Pediatric Neurology
  • Sleep Medicine
  • Neurosurgery

Background:

  • Sleep disordered breathing (SDB) in children can manifest as central apnoea and bradypnoea.
  • Arnold Chiari type 1 malformation is a rare condition affecting the cerebellum and brainstem.

Observation:

  • Three children (aged 3, 9, 13) with SDB showed significant central apnoea and bradypnoea.
  • Two children required non-invasive bilevel ventilation due to severe SDB.
  • Neurological examinations were normal in all affected children.

Findings:

  • Magnetic resonance imaging confirmed Arnold Chiari type 1 malformation in all children.
  • Urgent posterior fossa decompression was performed on all patients.
  • Following surgery, all children experienced normalized sleep breathing.

Implications:

  • Posterior fossa decompression is an effective treatment for SDB caused by Arnold Chiari type 1 malformation in children.
  • Early surgical intervention can resolve respiratory abnormalities associated with this condition.
  • Highlights the importance of neuroimaging in pediatric SDB evaluation.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Other Pulmonary Disorders01:17

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

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.

The initial evaluation of a patient's respiratory system...
Alterations in Respiration II01:30

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
