Randomized Controlled Trial
Sedative and cardiovascular effects of intranasal or intramuscular dexmedetomidine in healthy dogs.
To compare the clinical effects and sedation scores following either intranasal (IN) or intramuscular (IM) administration of dexmedetomidine in dogs. ⋯ Intranasal dexmedetomidine 0.02 mg kg-1 produced effective sedation with less bradycardia and more profound sedation compared to IM administration in healthy dogs and may be considered as an alternative route for dexmedetomidine administration in dogs.

To determine the dose of cis-atracurium needed to produce a moderate neuromuscular blockade (NMB) in pigs. ⋯ The doses described in our study may help researchers obtain a moderate NMB using cis-atracurium in pigs.

Randomized Controlled Trial
Caudal epidural anesthesia in mares after bicarbonate addition to a lidocaine-epinephrine combination.
To investigate the nociceptive and clinical effects of buffering a lidocaine-epinephrine solution with sodium bicarbonate in caudal epidural block in mares. ⋯ Alkalization of lidocaine-epinephrine solution is advantageous in shortening the duration of ataxia and hastening the onset of anesthesia in areas adjacent to the anogenital area, without reducing the duration of epidural anesthesia, in mares.

To compare the duration of action of atracurium in diabetic and nondiabetic dogs. ⋯ Diabetic dogs were older (9.9±0.3 compared with 6.8±0.7 years, p=0.0003). Group parameters were similar at onset and offset of NMB apart from HR at offset, which was higher for diabetics compared to nondiabetics (114±4 compared with 100±3 beats minute-1, respectively, p=0.004), Fe'Iso was higher in the diabetic group at onset (1.3±0.03% compared with 1.2±0.04%, p=0.026) and offset (1.4±0.03% compared with 1.3±0.03%, p=0.007), and temperature was higher for diabetics at onset (37.5±0.1 °C compared with 37.0±0.2 °C, p=0.012) and offset (37.5±0.1 °C compared with 36.9±0.2 °C, p=0.004). The duration of action of atracurium(tactile) and atracurium(EMG) were similar for both groups. CONCLUSIONS AND CLINICAL RELEVANCE: The duration of action of atracurium was similar in diabetic and nondiabetic dogs as indicated by tactile and EMG monitoring.

Randomized Controlled Trial
Effects of pneumoperitoneum and of an alveolar recruitment maneuver followed by positive end-expiratory pressure on cardiopulmonary function in sheep anesthetized with isoflurane-fentanyl.
To investigate the effects of pneumoperitoneum alone or combined with an alveolar recruitment maneuver (ARM) followed by positive end-expiratory pressure (PEEP) on cardiopulmonary function in sheep. ⋯ Abdominal deflation did not reverse the pulmonary function impairment associated with pneumoperitoneum. The ARM/PEEP improved respiratory compliance and reversed the oxygenation impairment induced by pneumoperitoneum with acceptable hemodynamic changes in healthy sheep.
