Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

5.2K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy Decannulation

2.7K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Trachea

6.3K
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...

Tracheostomy Care I: Pre-procedural Steps

1.9K
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Area of Science:

  • Pulmonology
  • Gastroenterology
  • Pathology

Background:

  • Tracheal diverticula are rare, often found incidentally via imaging.
  • Previous reports lacked histologic confirmation or involved patients with respiratory symptoms.
  • This case presents a unique asymptomatic presentation.

Purpose of the Study:

  • To report a rare case of tracheal diverticula in an asymptomatic individual.
  • To provide histologic confirmation of an incidentally found paraesophageal air-filled diverticulum.
  • To contribute to the understanding of tracheal diverticula presentations.

Main Methods:

  • Case report of a 60-year-old female presenting with primary hyperparathyroidism.
  • Imaging studies revealed an incidental right paraesophageal air-filled diverticulum.
  • Surgical resection and subsequent histopathologic examination of the specimen.

Main Results:

  • Histologic examination confirmed a multiloculated cystic cavity.
  • The lining epithelium was identified as respiratory-type columnar epithelium.
  • Associated findings included lymphocytic infiltrate and minor salivary glands.

Conclusions:

  • The case confirms tracheal diverticula can occur asymptomatically.
  • Histologic findings support the diagnosis in this unique presentation.
  • This case expands the known spectrum of tracheal diverticula.
