Use of abdominal thrusts is associated with improved rates of successful emesis induction in dogs

To evaluate the effect of abdominal thrusts as a synergistic procedure to IV apomorphine administration on the occurrence and rate of onset of successful induction of emesis in dogs.

31 client-owned dogs.

Dogs in which induction of emesis via IV apomorphine was prescribed by the attending clinician were prospectively randomized to either receive abdominal thrusts performed by a nurse or clinician or to have no physical interventions performed following IV apomorphine administration. Data collected included signalment, weight, reason for emesis, time from suspected ingestion to presentation, time from the dog's last meal to presentation, dose of apomorphine administered in milligrams, and time from apomorphine administration to emesis.

Emesis induction was successful in 14 of 14 (100%) of the dogs in the abdominal thrust group and 13 of 17 (76.5%) in the control group (P = .02). In dogs with successful emesis, median time to emesis was 90.5 seconds (range, 36 to 348 seconds) in the abdominal thrust group and 106 seconds (range, 37 to 360 seconds) in the control group (P = .29).

Abdominal thrusts were associated with an increased frequency of successful emesis in dogs following IV apomorphine, but did not shorten the rate of onset of emesis in dogs that vomited. Application of abdominal thrusts may be beneficial in dogs in which emesis is indicated and that do not have a clear contraindication.
