Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

1.1K
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...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

7.2K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Oxygen Delivering System III: Tracheostomy and T-piece

9.5K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

958
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

3.7K
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,...

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

2.9K
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:

  • Medical Imaging
  • Pulmonology
  • Computer-Aided Diagnosis

Background:

  • Virtual bronchoscopy (VB) software is often costly, limiting its adoption.
  • OsiriX offers a cost-effective alternative for reconstructing virtual endoscopic images.
  • This study evaluates OsiriX's capability for performing virtual bronchoscopy.

Purpose of the Study:

  • To assess the feasibility and utility of OsiriX software for virtual bronchoscopy.
  • To evaluate the visualization of small bronchi using OsiriX-generated virtual endoscopic images.
  • To determine if virtual bronchoscopy with OsiriX can guide transbronchial lung biopsy for lung nodule diagnosis.

Main Methods:

  • Chest computed tomography (CT) data from 10 patients with lung nodules were acquired.
  • Virtual bronchoscopic images were reconstructed using OsiriX version 5.5.
  • The visualization of distal bronchi (3rd-7th generations) and the path to lung nodules were assessed.

Main Results:

  • Successful reconstruction of virtual bronchoscopic images for all patients.
  • Visualization of third to seventh bronchi was achieved in most cases, with one exception due to tumor occlusion.
  • The virtual bronchoscopic path successfully reached lung nodules in all patients, enabling diagnosis in 5 cases via transbronchial biopsy.

Conclusions:

  • OsiriX is a practical and affordable software solution for virtual bronchoscopy.
  • The software facilitates the visualization of bronchial structures and aids in guiding biopsies.
  • OsiriX demonstrates potential for improving diagnostic accuracy in lung nodule evaluation.
