Comparison of anesthetic induction in cats by use of isoflurane in an anesthetic chamber with a conventional vapor or liquid injection technique

Abstract

Anesthetic induction in cats by use of a liquid injection technique was more rapid and provided a better quality of induction, compared with results for cats induced by use of a conventional vapor technique.

Feline procedural sedation and analgesia: When, why and how

“…Note that alternative methods for achieving PSA, such as chamber induction using inhalant anesthetics, can be useful to protect handlers from injury but may cause airway irritation 28 and an excitatory phase in patients, 29 in addition to the environmental concerns over waste anesthetic gases. 30 Moreover, this technique may be associated with increased risk of anesthetic-related morbidity or mortality due to the excessive inhalant anesthetic concentrations required to induce adequate sedation and avoid involuntary excitement.…”

Laboratory Mice Euthanasia: Speed Death and Animal Welfare

“…Propose to add more data to this controversial subject and in accordance with CONCEA Euthanasia Normative (associated with biometric analysis and the worldwide incidence of most used methodologies) we elaborated this study suggesting new procedure for the Swiss Webster Outbred Stock mice (male and adult) euthanasia. Based on this premise, the objectives of our work were: i) Investigation of the use of inhalation agents in the process of euthanasia of mice based on the calculation and evaluation of flow, noise and saturation of the chamber with different types of injector valves [20][21][22][23][24][25][26][27]; ii) Comparison of the effects and death dynamics through etological, cardiological, neurological, immunological, biochemical and behavioral systems between inhaled and injectable methods [28][29][30][31]; iii) The use of the combination of anesthetic induction with Isoflurane and CO 2 flow; iv) Financial cost to the each substance used in the respective processes.…”
