Insights

Computed tomography (CT) after bronchoscopy offers valuable insights into airway obstruction in children with suspected residual foreign bodies. This imaging technique detects obstructions missed by standard radiography, aiding diagnosis.

Area of Science:

  • Pediatric Pulmonology
  • Medical Imaging
  • Thoracic Surgery

Background:

  • Bronchoscopy is standard for airway foreign body removal.
  • Residual foreign bodies can cause persistent airway obstruction.
  • Accurate post-bronchoscopy assessment is crucial for pediatric patients.

Purpose of the Study:

  • To evaluate the added diagnostic value of computed tomography (CT) in children with suspected residual airway foreign bodies after initial bronchoscopy.

Main Methods:

  • Retrospective review of CT scans and medical records for nine pediatric patients.
  • Analysis of bronchial obstruction patterns and parenchymal abnormalities on CT.
  • Comparison of CT findings with second bronchoscopy or clinical follow-up.

Main Results:

  • CT identified bronchial obstruction in 8 of 9 patients, including focal, diffuse, and combined types, not visible on radiography.
  • CT revealed associated findings like emphysema, atelectasis, and consolidation.
  • Second bronchoscopy confirmed CT findings, showing retained fragments, mucus plugs, or granulation tissue.

Conclusions:

  • CT imaging after bronchoscopy provides significant additional information on the presence and characteristics of bronchial obstruction in children.
  • CT can guide further management by revealing residual foreign bodies or complications missed by initial procedures.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

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 to...
Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
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.

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 Management01:17

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 Intubation I: Procedure01:15

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...
