A retrospective case-control study evaluating systemic blood pressure and heart rate in dogs with brain herniation under general anesthesia.

Objective: To examine whether increased systemic arterial blood pressure (ABP) and decreased heart rate (HR) under inhalant anesthesia were suggestive of the Cushing reflex (CR) in dogs with neurological diseases based on magnetic resonance imaging (MRI) findings.

Study Design: Retrospective case-control study.

Animals: A sample of 137 client-owned dogs admitted to two veterinary teaching hospitals for diagnosis and patient care owing to suspected intracranial disease from 2005 to 2020.

Echocardiographic and hemodynamic effects of alfaxalone or dexmedetomidine based sedation protocols in cats with hypertrophic cardiomyopathy: a pilot study.

Objective: To report the effects of alfaxalone and dexmedetomidine based sedation protocols on echocardiographic and hemodynamic variables in cats with hypertrophic cardiomyopathy (HCM) during sedation and inhalational anesthesia.

Study Design: Prospective, randomized, experimental study.

Animals: A group of 10 client-owned cats with subclinical HCM.

Heart rate, arterial pressure and propofol-sparing effects of guaifenesin in dogs.

Objective: To evaluate the heart rate (HR) and systemic arterial pressure (sAP) effects, and propofol induction dose requirements in healthy dogs administered propofol with or without guaifenesin for the induction of anesthesia.

Study Design: Prospective blinded crossover experimental study.

Animals: A total of 10 healthy adult female Beagle dogs.

Repeatability and accuracy of fingertip pulse oximeters for measurement of hemoglobin oxygen saturation in arterial blood and pulse rate in anesthetized dogs breathing 100% oxygen.

Objective: To evaluate the repeatability and accuracy of fingertip pulse oximeters (FPO) for measurement of hemoglobin oxygen saturation in arterial blood and pulse rate (PR) in anesthetized dogs breathing 100% O.

Animals: 29 healthy client-owned anesthetized dogs undergoing various surgical procedures.

Procedures: In randomized order, each of 7 FPOs or a reference pulse oximeter (PO) was applied to the tongue of each intubated anesthetized dog breathing 100% O.

Comparison of isoflurane, sevoflurane, and desflurane as inhalant anesthetics in prairie rattlesnakes ().

Objective: To characterize induction and recovery characteristics of 3 commonly used inhalant anesthetics in prairie rattlesnakes (): isoflurane, sevoflurane, and desflurane.

Animals: 12 healthy adult prairie rattlesnakes.

Procedures: In a randomized crossover design, snakes underwent anesthetic induction with 5% isoflurane, 8% sevoflurane, or 18% desflurane, with a washout period of ≥ 7 days between anesthetic events.

Effects of intracoelomic alfaxalone-dexmedetomidine on righting reflex in common garter snakes (Thamnophis sirtalis): preliminary data.

Objective: To evaluate the effect of dexmedetomidine on alfaxalone immobilization in snakes.

Study Design: Nonblinded, crossover study.

Animals: A total of eight mature common garter snakes (Thamnophis sirtalis).

Effect of intracoelomic administration of alfaxalone on the righting reflex and tactile stimulus response of common garter snakes (Thamnophis sirtalis).

Objective: To determine the intracoelemic (ICe) dose of alfaxalone required to induce loss of righting reflex (LRR) in garter snakes (Thamnophis sirtalis) and to evaluate the tactile stimulus response in unanesthetized and alfaxalone-anesthetized snakes.

Animals: 8 healthy mature garter snakes.

Procedures: During the first of 3 phases, snakes received each of 3 doses (10, 20, and 30 mg/kg) of alfaxalone, ICe, with a 2-week washout period between treatments.

Ambulatory Anesthesia for the Exotic Veterinary Practitioner.

With the growing popularity in the ownership of nontraditional species, there is a growing need for veterinarians to be able to provide out-of-clinic health assessments on privately owned exotic species. Ambulatory anesthesia is often required for diagnostic and surgical procedures in remote or nonhospital settings. Anesthesia for diagnostic procedures is commonly used to ensure the safety of personnel and exotic veterinary patients, particularly when there is an inability to transport the animal to the clinic.

Isoflurane, sevoflurane and desflurane use in cane toads (Rhinella marina).

Anaesthetic chamber concentrations of isoflurane, sevoflurane and desflurane that resulted in loss of righting reflex within 15 minutes in 50 per cent of toads (Rhinella marina) exposed (ED50-LRR<15MIN) were identified. The median and range ED50-LRR<15MIN was 1.4 (0.

BEST-PRACTICE GUIDELINES FOR FIELD-BASED SURGERY AND ANESTHESIA ON FREE-RANGING WILDLIFE. II. SURGERY.

The principles of surgical asepsis apply to field surgeries with few exceptions. The minimum level for performance of surgeries in the field on free-ranging animals should be the same as for domestic animals undergoing surgery in animal hospitals. Surgeries in the field are typically done as part of research and management projects and usually involve a combination of biologists and veterinarians with the possibility of conflicts in scientific cultures.

BEST-PRACTICE GUIDELINES FOR FIELD-BASED SURGERY AND ANESTHESIA OF FREE-RANGING WILDLIFE. I. ANESTHESIA AND ANALGESIA.

Field anesthesia is often necessary for both invasive and noninvasive procedures on wild animals. We describe basic principles of safe anesthetic delivery, monitoring, and recovery for application in procedures involving free-ranging wildlife. For invasive procedures, the potential for immediate and lasting pain must be addressed and appropriate analgesia provided.
