Scoping review of quality of anesthetic induction and recovery scales used for dogs

Objective To compare, describe and assess the level of validation of all instruments measuring quality of induction and recovery from anesthesia in dogs. Databases used A search was performed using the electronic database PubMed to find articles containing an induction quality scale, a recovery quality scale or both in dogs. Articles not directly accessible through PubMed were obtained through the Auburn University Library website and Google Scholar. The phrases ‘induction scoring systems dogs’, ‘recovery scoring systems dogs’, ‘anesthetic induction score dogs’, and ‘anesthetic recovery score dogs’ were used for searches using the ‘best match search’ function. The time frame searched was from 1980 to May 2020. The search was conducted from March 2020 to May 2020. Conclusions A thoroughly tested and validated scale for measuring the quality of induction and recovery does not exist in the current veterinary literature. A large disagreement exists between studies on the use of induction and recovery scales, and many have reported inconsistent results with current instruments. It is recommended that an induction and recovery scale intended for wide-scale use be constructed and tested extensively for psychometric validation and reliability.
