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...

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...

General Anesthesia: Overview

2024
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational. General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
FAQs
Potency and onset address different clinical needs. Potency helps determine how effectively an agent produces the intended regional effect, whereas onset describes how quickly that effect develops. Pharmacologic selection must consider both properties alongside the planned need for surgical anesthesia or postoperative analgesia, because a rapidly acting drug may not have the same duration or distribution characteristics as another agent.
Duration determines how long targeted analgesia or anesthesia persists, while tissue distribution influences where the drug reaches within the treated region. These properties affect whether an agent better suits an operation, recovery period, or continuing postoperative pain control. Considering them together helps clinicians match local anesthetic behavior with the desired timing and extent of regional effect.
Dose-related toxicity makes the amount of local anesthetic a central safety consideration. Clinicians weigh the intended regional effect against the pharmacologic risk associated with increasing exposure, while also considering potency, tissue distribution, onset, and duration. This integrated assessment supports safer, patient-specific agent selection rather than choosing a drug solely for its ability to produce sensory blockade.
Peripheral Anesthesia can support surgical anesthesia when clinicians want pain control focused on a particular body region while preserving consciousness. Its regional focus may provide an alternative or complement to systemic anesthetic approaches. The choice depends on the procedure and the desired balance between targeted sensory control, drug characteristics, and patient-specific safety considerations.
Peripheral nerve blocks can extend targeted pain control beyond the operation into the postoperative period. By reducing pain from a selected body region, they may reduce reliance on systemic anesthetics and opioids. The expected benefit depends on the selected agent's duration, distribution, potency, and dose-related safety profile, which must be considered when planning patient-specific care.
Selection should integrate drug potency, onset, duration, tissue distribution, and dose-related toxicity rather than treating any single property as decisive. These variables help clinicians anticipate how quickly regional control may develop, how long it may last, and what safety considerations accompany the intended dose. Pharmacology therefore provides the framework for tailoring peripheral nerve blocks to surgical and postoperative goals.
