Insights

Pediatric obstructive sleep apnea (OSA) can involve paradoxical vocal cord movement (PVCM). Treatment of PVCM associated with OSA in children led to symptom resolution, indicating a link between these conditions.

Area of Science:

  • Pediatric Sleep Medicine
  • Otolaryngology
  • Respiratory Physiology

Background:

  • Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder in children.
  • Paradoxical vocal cord movement (PVCM) is typically associated with inspiratory stridor but can occur during sleep.

Observation:

  • This study describes three pediatric cases of OSA with concurrent PVCM identified during drug-induced sleep endoscopy (DISE).
  • Two patients had enlarged adenoids, while one had no other identified upper airway obstruction.
  • PVCM was observed during sleep in the context of airway obstruction.

Findings:

  • All three pediatric patients with OSA and PVCM experienced symptom resolution after treatment.
  • Treatments included adenoidectomy with antireflux medications or proton pump inhibitors alone.
  • Adenoidectomy and acid suppression appear effective in managing OSA with PVCM.

Implications:

  • This case series suggests PVCM can be a component of pediatric OSA, occurring during sleep-related airway obstruction.
  • Further research is needed to elucidate the etiology of PVCM in pediatric OSA.
  • Understanding the link between PVCM and OSA may improve diagnostic and therapeutic strategies for affected children.

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...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
