The association midazolam/droperidol was evaluated in the chemical restraint of 11 Landrace swines. Cardiac and respiratory rates were studied as well as rectal temperature and blood gas analisis after and before the midazolam (0.4mg/kg)/droperidol (0.4mg/kg) injection. The parametrical values and the blood gas analisis were performed during an hour period after drug administration, at 10 minutes intervals. At the same time, clinical trials were performed about the effectiveness of the tranquilization. Significant changes did not occur in the heart rate and acid-basic equilibrium. The respiratory rate decreased significantly, when compared to basal measurements. The set time of the drug action was that of 60 minutes, with an onset period of 3 minutes. During the tranquilization it was observed muscle relief, loss of the postural reflexos, abscence to enviromental stimulus and keeping of the pain reflex. The analysis of the obtained results enables to indicate the midazolam/droperidol association for the tranquilization of swines.
