Randomized Controlled Trial
Evaluation of tissue hemoglobin saturation (StO2) using near-infrared spectroscopy during hypoxemia and hyperoxemia in Beagle dogs.
To determine the relationship between tissue oxygen saturation (StO2) and oxygen delivery (D˙O2) during hypoxemia and hyperoxemia. ⋯ In this model of hypoxemia and hyperoxemia, the strong correlation between StO2 and D˙O2I suggests that StO2 can be used to estimate D˙O2.

Randomized Controlled Trial Comparative Study
Comparison of pulmonary artery and transpulmonary thermodilution cardiac output measurements in unsedated newborn calves.
To compare the agreement, repeatability and trending ability of transpulmonary thermodilution (TPTD) and pulmonary artery thermodilution (PATD) cardiac output (Q˙t) measurements in unsedated newborn calves. ⋯ We recommend that PATD remains the reference method to measure Q˙t in unsedated newborn calves. However, the robust results of the evaluation of the less invasive TPTD technique warrants further evaluation taking into account the difficulties reported in this study.

Randomized Controlled Trial
The effect of butorphanol on the incidence of dexmedetomidine-induced emesis in cats.
Τo evaluate the antiemetic effect of butorphanol (BUT) when co-administered with dexmedetomidine (DEX) in cats. ⋯ Butorphanol can be used to prevent emesis and reduce the incidence and the severity of nausea caused by DEX in cats. It seems that the combination of BUT and DEX is very useful not only when emesis could result in serious complications, but also to provide comfort and well-being in cats sedated for minor procedures.

Randomized Controlled Trial
The effects of diazepam or midazolam on the dose of propofol required to induce anaesthesia in cats.
Assess effects of benzodiazepine administration on the propofol dose required to induce anaesthesia in healthy cats, investigate differences between midazolam and diazepam, and determine an optimal benzodiazepine dose for co-induction. ⋯ Midazolam (0.2-0.5 mg kg(-1) ) and diazepam (0.3-0.5 mg kg(-1) ) administered IV after 2 mg kg(-1) propofol significantly reduced the propofol dose required for tracheal intubation.

Randomized Controlled Trial
The cardiopulmonary effects of dexmedetomidine infusions in dogs during isoflurane anesthesia.
To determine the cardiopulmonary changes associated with intravenous (IV) infusions of dexmedetomidine at equipotent isoflurane-dexmedetomidine concentrations compared with isoflurane alone. ⋯ Cardiopulmonary changes associated with LD were within clinically accepted normal ranges whereas HD produced clinically significant changes. The LD may be useful as an anesthetic adjunct in healthy dogs.
