Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

241
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...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

812
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...

Trachea01:22

Trachea

2.3K
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

29
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...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen01:16

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

758
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

2.0K
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...

Summary

Rigid bronchoscopy effectively treats post-tuberculosis tracheobronchial stenosis (PTTS), a common complication of tuberculosis. This minimally invasive procedure shows a 70% success rate in dilating airways and maintaining patency with silicone stents.

Area of Science:

  • Pulmonology
  • Interventional Bronchoscopy
  • Infectious Diseases

Background:

  • Tuberculosis (TB) healing can lead to tracheobronchial fibrosis and airway stenosis in 11-42% of patients.
  • Post-TB tracheobronchial stenosis (PTTS) is a significant cause of benign airway stenosis in Korea, leading to severe respiratory issues.
  • Rigid bronchoscopy has become the primary management for PTTS, replacing surgery.

Purpose of the Study:

  • To evaluate the efficacy and safety of rigid bronchoscopy for managing post-TB tracheobronchial stenosis (PTTS).
  • To identify factors associated with successful stent removal in PTTS patients.

Main Methods:

  • Patients with PTTS and American Thoracic Society (ATS) grade 3 dyspnea underwent rigid bronchoscopy.
  • Airway dilation techniques included ballooning, laser resection, and bougienation under general anesthesia.
  • Silicone stents were used to maintain airway patency, with planned removal after 1.5-2 years.

Main Results:

  • Rigid bronchoscopy demonstrated a 70% success rate in managing PTTS.
  • Acute complications occurred in less than 10% of patients, with no mortality.
  • Successful stent removal was linked to male sex, younger age, good baseline lung function, and absence of complete lobe collapse.

Conclusions:

  • Rigid bronchoscopy offers acceptable efficacy and safety for PTTS management.
  • The procedure is a viable option for patients suffering from airway stenosis due to prior tuberculosis.
