The records of 5736 general anaesthetics were reviewed to estimate the prevalence of, and identify the risk
factors for, the development of regurgitation during anaesthesia in dogs. Regurgitation was defined as the observed
passive passage of gastric contents into the oropharynx. Several variables were evaluated using univariable and
multivariable logistic regression analysis: breed, body mass, age, sex, type of procedure, expertise of anaesthetist, ASA
status, drugs administered, length of surgery and anaesthesia and local techniques performed.
Results showed that larger dogs, dogs with ASA status of 3 or higher, dogs undergoing abdominal surgery, imaging
procedures or both, longer anaesthetic duration, and dogs receiving medetomidine in comparison to acepromazine and an
opioid were more likely to suffer an episode of regurgitation.
