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...

Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN This experiment will use inductive coils to demonstrate the concept of inductor and inductance. Magnetic induction will be demonstrated using a rod magnet inserted into or extracted away from the core of a coil to induce a transient electromotive force (emf) voltage in the coil, measured by a voltmeter. This experiment will also demonstrate the mutual inductance between...

Loss of the righting reflex has long served as a standard behavioral surrogate for unconsciousness, also called hypnosis, in laboratory animals. Alterations in volatile anesthetic sensitivity caused by pharmacological interventions can be detected with a carefully controlled high-throughput assessment system, which may be adapted for delivery of any inhaled therapeutic.

The objectives of this experiment are to find the equivalent circuit parameters of a three-phase induction motor using the per-phase equivalent circuit and tests similar to those used in transformer characterization. In electrical engineering, an equivalent circuit (or theoretical circuit) can be determined for a given system. The equivalent circuit retains all characteristics of the original system,...

Inhalational Anesthetics: Overview

2024
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...
FAQs
Clinicians adjust the concentration of volatile anesthetic in the oxygen mixture according to the animal’s observed response during induction. This controls the amount of agent delivered to the lungs and subsequently available to enter the bloodstream. Careful adjustment supports a controlled progression toward anesthesia while allowing the clinician to respond to changes in the animal’s condition.
The chamber delivers anesthetic together with oxygen, allowing the animal to inhale the mixture through the lungs. The lungs provide the route by which the anesthetic agent enters the bloodstream and produces its intended effect. Maintaining this controlled gas mixture is therefore central to initiating inhalational anesthesia and supporting the transition to subsequent anesthetic delivery.
Observation of the animal’s responses is essential while the anesthetic mixture is being delivered. Clinicians use these responses to judge the progression of induction and determine when the animal can move to a face mask, endotracheal tube, or maintenance anesthetic system. Continuous attention also helps identify when concentration adjustment or handling changes may be needed.
Chamber induction can reduce the need for immediate needle placement by introducing anesthesia through inhalation before other procedures begin. This may facilitate a smoother transition to a face mask, endotracheal tube, or maintenance system. The approach is particularly relevant when initiating anesthesia in small animals, while observation and controlled agent delivery remain necessary throughout.
The clinician places the animal in the enclosed chamber, supplies an oxygen and volatile anesthetic mixture, and observes the response as induction progresses. Concentration can be adjusted during this period. Once an appropriate level of anesthesia is reached, the animal can transition to a face mask, endotracheal tube, or maintenance anesthetic system for continued care.
Adequate ventilation, appropriate scavenging, direct observation, and careful handling are all important safeguards. Ventilation and scavenging help limit anesthetic vapor in the surrounding environment, while observation helps clinicians assess the animal during induction. Handling should support a controlled transition between the chamber and the next anesthetic delivery method without compromising attention to the animal’s responses.
Its principal clinical use is initiating inhalational anesthesia in small animals before a procedure. The chamber is useful when clinicians want to begin anesthetic delivery without immediate needle placement and then move smoothly to a face mask, endotracheal tube, or maintenance system. Its value depends on controlled gas delivery, appropriate monitoring, ventilation, and environmental vapor control.
