Summary
Hydrogen peroxide 0.75% solution effectively prevents mirror fogging during indirect laryngoscopy. This safe and cost-effective method improves visualization of the larynx and hypopharynx for clinicians.
Area of Science:
- Otolaryngology
- Medical Devices
- Clinical Procedures
Background:
- Indirect laryngoscopy is essential for examining the larynx and hypopharynx.
- Mirror fogging during indirect laryngoscopy can impede visualization.
- Existing defogging methods have limitations.
Purpose of the Study:
- To evaluate hydrogen peroxide 0.75% w/v solution as a defogging agent for indirect laryngoscopy mirrors.
- To determine the safety and cost-effectiveness of this defogging method.
Main Methods:
- Indirect laryngoscopy examination was performed.
- A 0.75% w/v hydrogen peroxide solution was applied to the mirror as a defogging agent.
- Clinical observations on defogging efficacy and safety were recorded.
Main Results:
- The 0.75% hydrogen peroxide solution effectively prevented mirror fogging during indirect laryngoscopy.
- The defogging agent was found to be safe for clinical use.
- The method was identified as cost-effective.
Conclusions:
- Hydrogen peroxide 0.75% w/v solution is a safe and effective defogging agent for indirect laryngoscopy.
- This method offers a practical and economical solution to improve visualization during laryngeal examinations.

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
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,...

01:23Oxygen Delivering System III: Tracheostomy and T-piece
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

01:30Endoscopic Studies I: Bronchoscopy and Thoracoscopy
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 to...

02:23Autoxidation of Ethers to Peroxides and Hydroperoxides
Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.
01:26Tracheostomy Suctioning I: Pre-Procedural Steps
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.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

01:10PPE Use in Healthcare Settings II: Doffing
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.
