Minimum infusion rate and hemodynamic effects of propofol, propofol-lidocaine and propofol-lidocaine-ketamine in dogs.

Objective: To evaluate the effects of a constant rate infusion (CRI) of lidocaine alone or in combination with ketamine on the minimum infusion rate (MIR) of propofol in dogs and to compare the hemodynamic effects produced by propofol, propofol-lidocaine or propofol-lidocaine-ketamine anesthesia.

Study Design: Prospective, randomized cross-over experimental design.

Animals: Fourteen adult mixed-breed dogs weighing 15.

Comparison of a sidestream capnograph and a mainstream capnograph in mechanically ventilated dogs.

Objective: To compare the ability of a sidestream capnograph and a mainstream capnograph to measure end-tidal CO2 (ETCO2) and provide accurate estimates of PaCO2 in mechanically ventilated dogs.

Design: Randomized, double Latin square.

Animals: 6 healthy adult dogs.
