There are many commonly used routes for compound administration in laboratory mice and rats. However, certain protocols may require the use of less commonly used routes, including intradermal, intranasal, and intracranial injections. Specialized training is essential for these procedures to be performed successfully. Justification for these routes may need to be provided to gain Institutional Animal Care and Use Committee (IACUC) approval. …

This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum medially and the bony turbinates laterally. Beneath each curving turbinate is a groove or meatus. The nasolacrimal duct and most of the air-filled paranasal sinuses drain into the inferior and middle meatuses, respectively. Of the three sets of paranasal sinuses, only the maxillary and frontal can be readily examined. A continuous, highly vascular mucosa lines the entire nasal cavity and sinuses.

Topical medications are applied directly to the body surfaces, including the skin and mucous membranes of the eyes, ears, nose, vagina, and rectum. There are many classes of topical medications, such as creams, ointments, lotions, patches, and aerosol sprays. Medications that are applied to the skin to produce slow, controlled, systemic effect are also referred to as transdermal. Transdermal absorption can be altered if lesions, burns, or breakdowns are present at the application site. Many transdermal medications are delivered via adhesive patch to achieve the slow, controlled, systemic effect. The patch should be applied to clean and hairless skin areas that do not undergo excessive movement, such as the back of the shoulder or thigh. Other topical creams or eye ointments should be applied according to the packaging and manufacturer instructions using an application device. When instilling eardrop medications, never occlude the ear canal, as this may increase pressure and rupture the ear drum.
Medications that can be administered via a topical route include antibiotics, narcotics, hormones, and even chemotherapeutics. This requires adherence to the five "rights" of medicati…
