“…These values were lower than those found by Garcia-Pereira et al 14 Following termination of anesthetic maintenance and CRI, all calves recovered uneventufully and no adverse effects were observed at recovery. Nevertheless, recovery time was greater than that observed by Cantalapietra et al 16 , which reported a mean of 4.6 minutes to sternal recumbency and 6.7 minutes to standing position in cattle anaesthetized with 1 MAC of isoflurane for 90 minutes.…”

PURPOSE:To assess the hemodynamic changes and bispectral index (BIS) following administration of a continuous rate infusion (CRI) of butorphanol in isoflurane-anesthetized calves. METHODS:Eight calves weighing 110 ± 12 kg were included in the study. Anesthesia was induced with 5% isoflurane in O 2 delivered via face mask and maintained with end-tidal concentration of 1.4%. IPPV was set to a peak inspiratory airway pressure of 15 cmH 2 O and respiratory rate of six breaths minute -1 . Forty minutes after the start of anesthetic maintenance, 0.1 mg kg -1 butorphanol was administered intravenously, followed by a CRI of 20 µg kg -1 minute -1 . Hemodynamic variables and BIS were recorded before butorphanol administration (T0), and at 10, 20, 40 and 80 minutes following the CRI. Anesthesia was discontinued after the last recording and the calves were allowed to recover. The time to sternal recumbency (SRE) and standing (ST) were evaluated. RESULTS:There were no significant differences between the moments in all hemodynamic variables and BIS. The time to SRE and ST was 9 ± 5 and 14 ± 7 minutes, respectively. CONCLUSION:The continuous rate infusion did not produce clinically relevant changes in hemodynamic or bispectral index values compared to baseline in mechanically ventilated and unstimulated calves anesthetized at 1.4% isoflurane.

“…The results of this study suggest that the use of lidocaine CRI at 50 mg kg −1 minute −1 in calves undergoing umbilical surgery reduces the required concentration of isoflurane by approximately 17%. There appears to be no published minimum alveolar concentration (MAC) of isoflurane for calves, but in adult cattle it is 1.14% (Cantalapiedra et al. 2000).…”

“…In ruminants, isoflurane has an induction concentration of 3-5% and an anesthetic concentration of 1.5-3% [7], while sevoflurane has an induction concentration of 4-6% and an anesthetic concentration of 2.5-4% [14,31]. In this study, the concentration of isoflurane was 2.3% (2-5) and that of sevoflurane was 4.07% (3-5) for surgery.…”

Background: Inhalation anesthesia is the preferred method for use on many animal species, including ruminants, due to its superiority over the injectable anesthetics. The most commonly used inhalation anesthetics are isoflurane and sevoflurane The aim of the study was to investigate the effects of isoflurane and sevoflurane anesthesia on the cardiovascular system of calves. Materials, Methods & Results:A total of 20 calves (11 male, 9 female) between 1 and 6 months in age and 50 to 85 kg in body weight were used. The calves were divided randomly into two groups of 10 each, with one group being administered isoflurane and the other sevoflurane. An intramuscular dosage of 0.1 mg/kg of xylazine was administered to the calves as premedication. Induction was performed 10 min after calves were given an intramuscular dosage of 4 mg/kg of ketamine. Inhalation anesthesia was maintained with isoflurane or sevoflurane in 100% oxygen saturation. Before anesthesia, after induction and at intervals of 5,10,15,20,25,30, 45, and 60 min of anesthesia, the body temperature, heart rate, and respiratory rate of the calves were recorded. Additionally, before anesthesia, after induction and at intervals of 15, 30, 45, and 60 min of anesthesia, serum electrolyte (Na
