Comparison of sevoflurane with isoflurane for rapid mask induction in midazolam and butorphanol-sedated dogs.

摘要: Rapid mask induction can be a useful technique for veterinary patients, although it is often accompanied by exaggerated excitement responses in unpremedicated animals (Mutoh et al.: Jpn. J. Vet. Anesth. Surg. 26, 109–116; Med. Sci. 57, 1007–1013; 1121–1124; 1995). The aim of this study was to compare sevoflurane with isoflurane rapid six dogs sedated combination midazolam (0.1 mg/kg) and butorphanol (0.2 mg/kg). Induction (5 %, 2.4 minimum alveolar concentration [MAC]) O2 resulted shorter time loss the palpebral reflex, negative tail clamp response, successful intubation than (3 %, MAC) O2. There were no changes heart rate or mean arterial blood pressure during sevoflurane, whereas an increase observed induced isoflurane. A decrease respiratory compared pre-induction induction, associated mild acidosis, characterized PCO2, measured at end period both groups. None had episodes induction-related complications. These results suggest that produce smooth onset butorphanol-sedated dogs. Sevoflurane more suitable since provides faster lower blood/gas partition coefficient.
