Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

151
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

116
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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

84
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

259
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...

Drugs Affecting GI Tract Motility: Other Laxatives01:20

Drugs Affecting GI Tract Motility: Other Laxatives

217
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

670
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....

Summary

New forced-air drying systems (FADS) effectively dry endoscopes, unlike current automated endoscope reprocessor (AER) cycles. This study shows FADS ensures complete endoscope drying, crucial for preventing patient infections from contaminated medical instruments.

Area of Science:

  • Medical device reprocessing
  • Infection control
  • Endoscopy

Background:

  • Inadequate endoscope drying is linked to patient infections.
  • Current guidelines recommend 10 minutes of forced air for endoscope channel drying.
  • Existing automated endoscope reprocessor (AER) cycles may not adequately dry endoscopes.

Purpose of the Study:

  • To evaluate a new forced-air drying system (FADS) for endoscopes.
  • To assess the effectiveness of FADS in drying endoscope channels and components.
  • To compare FADS drying efficacy against standard AER cycles.

Main Methods:

  • Drying was assessed using droplet detection cards, visual inspection, and borescope examinations.
  • Evaluations were conducted after AER alcohol flush/air purge cycles and after 10-minute FADS cycles.
  • The study included 22 gastroscopes and 20 colonoscopes.

Main Results:

  • 100% of endoscopes remained wet after standard AER cycles.
  • Substantial fluid was observed during the initial FADS cycle.
  • Following the FADS cycle, 100% of endoscopes were completely dry with no detected retained fluid.

Conclusions:

  • Standard AER cycles are insufficient for complete endoscope drying.
  • The new FADS demonstrated 100% effectiveness in drying endoscopes.
  • This highlights the need to reassess current drying practices and adopt validated methods like FADS.
