Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017
The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

COVID-19 / Coronavirus Outbreak: Protecting The Airway - Endotracheal Intubation

2020
In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff to reduce the risk of infection. COVID patients often need mechanical ventilation due to progredient respiratory insufficiency, so an endotracheal intubation becomes a critical procedure in managing these patients. This procedure has an increased risk of infection due to aerosol formation and working with...

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals ("The Guide") states that pain assessment and alleviation are integral components of the veterinary care of laboratory animals. The definition of anesthesia is the loss of feeling or sensation. It is a dynamic event involving changes in anesthetic depth with respect to an animal's metabolism, surgical stimulation, or variations in the...

2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Anesthesia is an essential component of rabbit surgical and experimental procedures because it prevents pain, reduces stress responses, and helps immobilize the animal during handling and manipulation when general anesthesia is...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Pigs are commonly used in biomedical and surgical research because of their anatomical and physiological similarities to humans. During procedures, anesthesia prevents pain, reduces stress, limits movement, and supports animal...
FAQs
Different devices address different airway problems and support levels. Face masks deliver oxygen without placing a conduit in the trachea, while oral and nasal airways help open obstructed upper-airway passages. Supraglottic devices provide another airway option, and endotracheal tubes create a sealed route into the trachea when a sealed conduit is needed.
Laryngoscopes make tube placement possible by providing direct or video-assisted visualization of the airway during insertion. This visual guidance helps the operator direct an endotracheal tube into the trachea rather than relying only on external positioning. The distinction between direct and video-assisted viewing is important when selecting equipment for routine or difficult airway management.
Airway management has two linked goals: maintaining a passage for air and supporting gas exchange. A face mask or oral or nasal airway may help preserve patency and deliver oxygen, whereas a tracheal tube can support controlled ventilation through a sealed conduit. Matching the device to the immediate requirement helps reduce hypoxia risk during anesthesia or sedation.
Selection depends on the clinical setting, the required degree of airway support, and whether the airway is routine or difficult. The same set of tools can therefore be used differently in anesthesia, sedation, emergency care, the operating room, and critical care. Choosing among masks, airways, supraglottic devices, laryngoscopes, and tubes allows support to increase when needed.
A practical sequence begins with a face mask for oxygen delivery or an oral or nasal airway to help open an obstructed passage. If additional support is required, a supraglottic device or endotracheal tube may be chosen. When tracheal access is needed, a laryngoscope provides direct or video-assisted visualization to guide tube placement.
These tools are used during sedation, emergency care, and critical care as well as anesthesia. Their roles may include delivering oxygen, opening an obstructed upper-airway passage, supporting ventilation, or establishing a sealed route into the trachea. This range makes them relevant wherever clinicians must maintain airway patency or provide respiratory support.
Appropriate selection helps maintain airway patency, support oxygenation, and facilitate controlled ventilation. In practice, these outcomes can reduce the risk of hypoxia and make airway management safer across routine and difficult situations. The available options also allow clinicians to match the intervention to the needed level of support, from oxygen delivery to tracheal tube placement.
