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.

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...

In this video, we demonstrate the topical testing assay to determine the toxicity of a potential insecticide on adult female mosquitoes. Using a dopamine receptor antagonist that causes lethal inhibition of neurotransmission in mosquitoes, this method describes a way to evaluate the toxic effects of insecticides upon topical application.

Genes can be manipulated during development of the cortex or the hippocampus of the rat via in utero electroporation (IUE) at E16, to enable fast and targeted modifications in neuronal connectivity for later studies of behavior or neuropathology in adult animals. Postnatal in vivo imaging for control of IUE success is performed by bioluminescence of activating co-transfected luciferase.

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...
FAQs
Lidocaine diffuses into nearby nerve endings and blocks voltage-gated sodium channels. These channels normally support membrane depolarization, an electrical change needed for sensory nerve signaling. By preventing depolarization, lidocaine interrupts transmission of pain signals along the affected sensory nerves. This local mechanism explains why sensation is reduced in the treated area rather than throughout the entire body.
The localized action confines the anesthetic effect to the treated area, which can improve comfort during a minor procedure without producing the broader effects associated with systemic or general anesthesia. This distinction makes topical lidocaine useful when temporary reduction of sensation is needed at the skin or mucous membranes while maintaining a more limited area of action.
Skin and mucous membranes are the application surfaces through which lidocaine reaches nearby nerve endings. Because the anesthetic acts locally at these sites, the selected surface corresponds to where reduced sensation is needed. This allows the method to support procedures involving external skin as well as procedures involving mucosal tissue, including applications in dermatology and dentistry.
These formulations provide different ways to place lidocaine on the skin or mucous membranes, while supporting the same local anesthetic purpose. Creams, gels, ointments, sprays, and patches broaden how the medication can be applied across clinical settings. The overview associates these forms with dermatology, dentistry, wound care, and diagnostic procedures rather than assigning one formulation to every use.
Lidocaine topical anesthesia is used across several localized medical contexts, including dermatology, dentistry, wound care, and diagnostic procedures. In each setting, application is directed toward an area where temporary reduction of sensation may improve patient comfort during a minor procedure. Its usefulness comes from combining localized action with multiple available delivery forms.
The intended outcome is temporary loss or reduction of sensation in the treated area, helping lessen pain during a minor medical procedure. Because lidocaine blocks pain-signal transmission in nearby sensory nerves, comfort can improve while the effect remains localized. The method is therefore suited to procedures where local pain control is sufficient and broader anesthesia is not required.
