Summary
The Ambu aScope, a disposable videoscope, is effective for airway evaluations but can rarely cause serious patient injury, including foreign body events. Vigilance is crucial to mitigate these risks.
Area of Science:
- Medical Devices
- Patient Safety
- Pulmonology
Background:
- The Ambu aScope is a widely used disposable flexible videoscope in various medical procedures.
- While effective, adverse events associated with its use have been reported.
- Understanding these events is crucial for patient safety.
Purpose of the Study:
- To analyze patient-related adverse events associated with the Ambu aScope using the FDA MAUDE database.
- To identify the types and frequencies of adverse events linked to Ambu aScope use.
- To assess the potential risks and consequences of these adverse events.
Main Methods:
- Retrospective analysis of the FDA Manufacturer and User Facility Device Experience (MAUDE) database.
- Inclusion criteria: Patient-related adverse events involving Ambu aScope from January 1, 2000, to December 15, 2023.
- Search terms: "Ambu" and "Ascope."
Main Results:
- Thirty unique adverse events were identified.
- Twenty-one events involved patient injury; nine involved device malfunction.
- Key injuries included foreign body events (8), airway obstruction/hypoxia (3), and anxiety/cardiac arrest (1).
Conclusions:
- The Ambu aScope is a valuable tool for airway evaluations.
- Rarely, it can act as a foreign body, leading to severe patient harm.
- Continuous monitoring and reporting of adverse events are essential for improving device safety.

238
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...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
