RESUMO
Objetivou-se com este estudo avaliar o efeito analgésico trans e pós-operatório da eletroacupuntura em onda denso-dispersa e frequências 3 e 200Hz, nos pontos E44, R3 e BP4, compará-lo com a analgesia promovida pelos pontos BP6, E36 e VB 34, e pela morfina, em cadelas submetidas à ovariosalpingohisterectomia (OSH). Teve-se como hipótese que a eletroacupuntura nos pontos E44, R3 e BP4 resultaria em controle da dor trans e pós-operatória melhor ou igual àquele promovido pela eletroacupuntura nos pontos BP6, E36 e VB34 e pela morfina. Trinta e seis cadelas submetidas à cirurgia eletiva de OSH foram distribuídas em blocos ao acaso em três grupos com 12 animais. Em dois grupos foi realizada eletroacupuntura denso-dispersa, com frequência de 3 e 200Hz, sendo que, no primeiro grupo (GEA), foram estimulados os pontos BP4, E44, R3 e, no segundo grupo (GEB), os pontos BP6, E36, VB34...
Thirty-six dogs undergoing elective ovariohysterectomy surgery were randomly distributed into 3 groups of 12 animals each. In the first group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP4, ST44, KID3 points and 1.5mL of saline was given intramuscularly (GEA group). For the second group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP6, ST36, GB34 points and 1.5mL of saline given intramuscularly (GEB group)...

This research aimed to evaluate the effect of metoclopramide and ranitidine in the prevention of gastroesophageal reflux episodes during anesthetic procedures. Ninety healthy female dogs were submitted to elective ovariosalpingohisterectomy, randomly divided into three groups of 30 animals. The control group received only the anesthetic protocol. The metoclopramide group received an intravenous bolus of 1mg/kg, and continuous infusion (1 mg/kg/h intravenously) immediately after anesthetic induction. The ranitidine group received an intravenous bolus of 2 mg/kg, 6 h before anesthesia. Anesthesia (acepromazine, propofol and isofluorane) was standardized and the esophageal pH variations were recorded. Esophagoscopy was carried out after surgery. No difference (p<0.05) was verified in the reflux episodes between the groups. Seven animals presented reflux. Metoclopramide in bolus and continuous infusion, as well as ranitidine, 6 h before anesthesia, did not influence the reduction of the incidence of gastroesophageal reflux.
