Determination of cardiac output in neonatal foals by ultrasound velocity dilution and its comparison to the lithium dilution method.
To compare cardiac output (CO) measured by use of lithium dilution (LiDCO) and ultrasound velocity dilution (UDCO) in conditions of high, intermediate, and low CO in anesthetized foals. ⋯ When compared with LiDCO, the UDCO technique has acceptable clinical utility for measuring CO in healthy anesthetized newborn foals.

Antimicrobial therapy and aerobic bacteriologic culture patterns in canine intensive care unit patients: 74 dogs (January-June 2006).
Describe antimicrobial therapy and aerobic bacteriologic culture patterns in canine intensive care unit (ICU) patients in a university hospital. ⋯ Antimicrobial use was extensive in this patient population, but when available, MIC results were used to guide antimicrobial therapy. Many patients with negative cultures continued to receive antimicrobial therapy. Multidrug resistant bacteria were more likely in cultures taken after 48 hours of hospitalization.

Randomized Controlled TrialNoninvasive ventilation in cats.
The primary objective of this study was to assess the feasibility of noninvasive mechanical ventilation (NIV) in cats. The secondary objective was to determine whether cardiovascular parameters and anesthetic drug requirements associated with noninvasive ventilation differ from those associated with invasive ventilation. ⋯ NIV of cats is possible. However, currently it does not confer any cardiovascular benefit over invasive ventilation and drug requirements are similar. Use of a correctly fitted mask is essential for successful NIV as air leaks account for the observed discrepancy between inspiratory and expiratory volumes. Further investigation into this modality is warranted.

Randomized Controlled TrialComparison of fluid types for resuscitation after acute blood loss in mallard ducks (Anas platyrhynchos).
The purpose of this study was to determine the LD(50) for acute blood loss in mallard ducks (Anas platyrhynchos), compare the mortality rate among 3 fluid resuscitation groups, and determine the time required for a regenerative RBC response. ⋯ The LD(50) for acute blood loss in mallard ducks was 60% of their total blood volume. Although no statistical difference in mortality rate was appreciated among the 3 fluid resuscitation groups, a trend of decreased mortality rate was observed in the HBOCS group. An early regenerative response was apparent following acute blood loss.

Use of thromboelastography in dogs with immune-mediated hemolytic anemia: 39 cases (2000-2008).
To analyze thromboelastograms (TEGs) of naturally occurring cases of immune-mediated hemolytic anemia (IMHA) in order to identify whether a hypercoagulable state was present and whether its presence was associated with differences in survival. ⋯ The majority of dogs with IMHA were hypercoagulable as measured by TEG. A normal CI was associated with a worse outcome in this patient population. TEG may provide additional and complementary information to prothrombin time and partial thromboplastin time relating to coagulation status in dogs with IMHA and may help predict prognosis and potentially guide clinical decisions to utilize anticoagulant drugs.
