Summary
Pediatric tonsillotomies and adenoidectomies generate significant aerosols, comparable to coughing, posing potential viral transmission risks. Tympanostomies, however, are low-risk aerosol procedures.
Area of Science:
- Otorhinolaryngology
- Aerosol Science
- Infectious Disease Control
Background:
- Healthcare workers face risks from aerosol-generating procedures.
- Understanding aerosol generation in pediatric ENT surgeries is crucial for infection control.
Purpose of the Study:
- To quantify aerosol generation during pediatric tonsillotomies, adenoidectomies, and tympanostomies.
- To identify surgical phases and instruments contributing most to aerosol production.
Main Methods:
- Aerosol concentrations (0.3-10.0 μm) were measured using an Optical Particle Sizer in 35 pediatric procedures.
- Surgical phases and instruments were logged; operating room background and coughing served as references.
Main Results:
- Tonsillotomies and adenoidectomies produced significantly higher aerosol concentrations than tympanostomies and background levels.
- Aerosol levels during tonsillotomies were comparable to coughing.
- No significant difference in aerosol generation was found between suction, electrocautery, cold instruments, and paracentesis.
Conclusions:
- Tympanostomies are low-risk aerosol-generating procedures.
- Pediatric tonsillotomies are significant aerosol producers, with theoretical intraoperative viral transmission risk.
- Further research into mitigating aerosol generation during tonsillectomies and adenoidectomies is warranted.

01:25Suctioning the Oropharyngeal Airway
197
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
488
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
