Use of computed tomography to evaluate pathologic changes in the lungs of calves with experimentally induced respiratory tract disease.

Objective: To optimize methods for the use of computed tomography (CT) to assess pathologic changes in the lungs of calves and to determine the effect of treatment on lung consolidation.

Animals: 10 male Holstein calves.

Procedures: Calves were anesthetized to facilitate CT imaging of the thorax.

Cardiopulmonary and acid-base effects of desflurane and sevoflurane in spontaneously breathing cats.

The cardiopulmonary effects of desflurane and sevoflurane anesthesia were compared in cats breathing spontaneously. Heart (HR) and respiratory (RR) rates; systolic (SAP), diastolic (DAP) and mean arterial (MAP) pressures; partial pressure of end tidal carbon dioxide (PETCO2), arterial blood pH (pH), arterial partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2); base deficit (BD), arterial oxygen saturation (SaO2) and bicarbonate ion concentration (HCO3) were measured. Anesthesia was induced with propofol (8+/-2.
