Personal Protective Equipment01:20

Personal Protective Equipment

2.1K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Endoscopic Procedures III: Video Capsule Endoscopy

542
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,...

PPE Use in Healthcare Settings I: Donning

1.5K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Tracheostomy Care II: Procedure

1.0K
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...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

2.0K
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.

Area of Science:

  • Medical Devices
  • Infectious Disease Control
  • Protective Equipment

Background:

  • Healthcare professionals, particularly otolaryngologists, face high risks during aerosol-generating procedures like flexible fiberoptic endoscopy.
  • Standard personal protective equipment may not fully mitigate exposure to infectious particles during such procedures.
  • The COVID-19 pandemic highlighted the need for improved personal protective equipment, with face shields emerging as a preferred alternative to face masks for broader protection.

Purpose of the Study:

  • To compare the protective efficacy of a novel enhanced face shield design against a standard face shield.
  • To evaluate the ability of face shields to prevent aerosolized particle contamination in a controlled laboratory setting.

Main Methods:

  • A flexible fiberoptic endoscope was utilized within both standard and enhanced face shield designs.
  • Simulated coughs were generated using fluorescein dye expelled from an atomizer within a test participant's mouth.
  • Ultraviolet lighting and visual inspection were used to quantify dye splatter and assess contamination areas.

Main Results:

  • The standard face shield design showed significant aerosolized dye splatter, particularly along the lower lateral aspects, leading to environmental contamination.
  • The enhanced face shield design successfully maintained a barrier, preventing the aerosolized dye from spreading.

Conclusions:

  • The enhanced face shield design offers superior protection against aerosolized particles compared to standard designs.
  • This improved face shield can enhance safety for medical personnel during procedures like flexible fiberoptic endoscopy.
  • The enhanced face shield represents a valuable advancement in personal protective equipment for healthcare professionals and the public.
