The paca is a South American rodent whose handling, tranquilization or anesthesia offers a large field of research due to rare existing issues. Twelve adult female pacas were used, separated in 6 pen, and were caught with a net made of polypropylene attached to a wire loop and then sent to a room where the abdominal hair clipping was done. Afterwards, the female was placed in an iron bar squeeze cage. The ultrasonography session was made in B mode with a two-frequency sectorial electronic transducer of 5.0 and 7.5 MHz. Intending to reduce the stress caused by the procedures, the tranquilization of females was made with oral taking of diazepam and midazolam maleate. Both presented effectiveness in tranquilization of pacas previously and during sessions, being the midazolam maleate the one that better facilitated the animal handling.
