Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

235
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...

General Anesthesia: Overview01:24

General Anesthesia: Overview

245
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

1.8K
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

119
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

348
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

886
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....

Area of Science:

  • Pulmonology
  • Anesthesiology
  • Medical Imaging

Background:

  • Atelectasis is a known complication of general anesthesia.
  • Recent studies show a high incidence (up to 89%) of intraprocedural atelectasis during bronchoscopy under general anesthesia.
  • Factors like duration of anesthesia and higher body mass index (BMI) contribute to its development.

Purpose of the Study:

  • To review the discovery and significance of intraprocedural atelectasis during bronchoscopy.
  • To summarize current and emerging strategies for mitigating this complication.

Main Methods:

  • Literature review of studies on intraprocedural atelectasis during bronchoscopy.
  • Analysis of factors influencing atelectasis development.
  • Evaluation of proposed prevention strategies.

Main Results:

  • Intraprocedural atelectasis significantly impacts peripheral bronchoscopy by causing imaging discrepancies and obscuring targets.
  • Ventilatory strategies have proven effective and well-tolerated in reducing atelectasis.
  • Patient positioning and preprocedural strategies require further investigation.

Conclusions:

  • Bronchoscopists must be aware of intraprocedural atelectasis and implement preventive measures.
  • Effective strategies, particularly ventilatory ones, can mitigate this complication.
  • Further research into other preventive approaches is warranted.
