The aim of this study was to determine whether or not canine lymphoma could be associated with a clinically relevant type B hyperlactatemia (> 2.5 mmol/L). The medical database from the University of Montreal Veterinary Medical Teaching Hospital was searched for confirmed cases of canine lymphoma with a blood lactate measurement. Information retrieved included stage, clinical observations compatible with causes of type A and B hyperlactatemia other than cancer, hepatic involvement, and drugs administered. ⋯ A significant association (P = 0.01) was identified between corticosteroid administration and hyperlactatemia. Cytological, echographic, and/or biochemical tests revealed hepatic changes in all hyperlactatemic dogs. Lymphoma alone may not be sufficient to explain clinically relevant hyperlactatemia in dogs.

Iron is essential to virtually all living organisms and is integral to multiple metabolic functions. The most important function is oxygen transport in hemoglobin. ⋯ Severe iron deficiency is characterized by a microcytic, hypochromic, potentially severe anemia with a variable regenerative response. Iron metabolism and homeostasis will be reviewed, followed by a discussion of diagnostic testing and therapeutic recommendations for dogs and cats with iron deficiency anemia.

Acute respiratory distress syndrome (ARDS) was diagnosed in 2 dogs with acute dyspnea. Short-term positive pressure ventilation and intense critical and nursing care were provided. ⋯ Few reports describe successful recovery from ARDS. Due to advances in positive pressure ventilation and improvement in the supportive care of critically ill veterinary patients, the prognosis for ARDS may improve.

The purpose of this study was to assess the use of surface area derived tidal volume in anesthetized ventilated dogs (n = 71, random assignment) compared to settings by experienced personnel. There was no significant difference (P = 0.1030) between methods (p(a)CO(2) of 43.1 ± 7 mmHg and 39.8 ± 7 mmHg, respectively). Surface area derived tidal volume can achieve satisfactory ventilation.

This study assessed the intraoperative analgesic effects of intravenous lidocaine administered by a constant rate infusion (CRI) in surgical canine patients. A prospective, blinded, randomized study was designed with 2 treatment groups: A (lidocaine) and B (placebo), involving 41 dogs. All patients were premedicated with acepromazine and buprenorphine, induced with propofol and midazolam; anesthesia was maintained with isoflurane in oxygen. ⋯ Fentanyl was used as a supplemental analgesic when intraoperative nociceptive response was not controlled with the maximum dose of lidocaine infusion. There was a significantly lower use of supplemental intraoperative analgesia in the lidocaine than in the placebo group. Group B dogs had almost twice as high a risk of intraoperative nociceptive response as group A dogs.
