Insights

The incidence of subglottic stenosis in children after endotracheal intubation is high. Further research is needed to identify risk factors for this condition.

Area of Science:

  • Pediatric critical care medicine
  • Otolaryngology
  • Respiratory medicine

Background:

  • Endotracheal intubation is a common procedure in pediatric intensive care units.
  • Subglottic stenosis is a potential complication of prolonged intubation in children.
  • Early identification and management are crucial for favorable outcomes.

Purpose of the Study:

  • To determine the incidence of subglottic stenosis in pediatric patients following endotracheal intubation.
  • To assess the relationship between laryngeal alterations post-extubation and the development of subglottic stenosis.

Main Methods:

  • A prospective study was conducted on 123 children in a tertiary care hospital's pediatric intensive care unit.
  • Flexible fiber-optic nasolaryngoscopy was performed after extubation and during follow-up.
  • Children were categorized based on laryngeal findings to assess the development of subglottic stenosis.

Main Results:

  • The overall incidence of subglottic stenosis was 11.38% (95% CI, 6.63-17.94%).
  • All children diagnosed with subglottic stenosis exhibited moderate to severe laryngeal alterations immediately after extubation.
  • No chronic changes were observed in children with normal initial post-extubation laryngeal examinations.

Conclusions:

  • The incidence of subglottic stenosis in this cohort is notably high.
  • Moderate to severe laryngeal alterations post-extubation are indicative of increased risk.
  • Further investigation into specific risk factors is warranted to guide preventative strategies.

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...

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...

Endotracheal Intubation I: Procedure

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

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 interventions are...

Endotracheal Intubation II: Nursing Management

Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...
Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
