Article: Successful treatment of acute respiratory distress syndrome in 2 dogs.
[show abstract] [hide abstract]
ABSTRACT: 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. Both dogs improved and were discharged. 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 Canadian veterinary journal.

Article: Intermediate syndrome of chlorpyriphos toxicity (Polaris) in a caracal (Caracal caracal).
[show abstract] [hide abstract]
ABSTRACT: A 5-yr-old spayed female caracal (Caracal caracal) was presented with complaints of acute onset of mental dullness, ataxia, and ventroflexion of 24-hr duration. The animal's garden territory was sprayed a day earlier with an organophosphate (OP) insecticide (chlorpyriphos-methyl). The caracal was treated for OP toxicosis and mildly improved. It was discharged a day later at the owner's request, although clinical signs did not resolve. During the following week, the caracal was confined to prevent further toxin exposure but did not improve and was presented 8 days later with similar clinical signs. Serum butyril-cholinesterase activity was markedly low. The relatively long interval from OP exposure, along with the duration of clinical signs, suggested an intermediate syndrome of OP toxicity. The caracal was treated symptomatically and progressively improved. It was discharged after 8 days of hospitalization and made full recovery 30 days later. This is the first report of OP toxicity in a caracal, suspected to progress to an intermediate syndrome of OP poisoning.Journal of Zoo and Wildlife Medicine 03/2011; 42(1):144-8. · 0.38 Impact Factor -
Article: Axial pattern flap based on a cutaneous branch of the facial artery in cats.
[show abstract] [hide abstract]
ABSTRACT: To describe the cutaneous portion of the facial artery in cats and an axial pattern flap based on a branch of this artery. Ex vivo study. Cat cadavers (n=12). The common carotid artery was identified, cannulated, and infused with methylene blue to assist in the identification of the facial artery, which was subsequently cannulated and selectively infused with methylene blue. The main trunk of the artery and its branches were dissected. The extent of blue coloration of the skin was evaluated on the contralateral side of the same specimen after infusing methylene blue into the facial artery. In 4 specimens, the flap was raised along previously defined borders and adequacy of perfusion was evaluated. The area of skin perfused by the facial artery extended from the lower eyelid dorsally, to the angularis oris cranially, and the wing of the atlas caudally. Borders of the skin flap were defined on the basis of the anatomic dissection and skin coloration after selective infusion of the facial artery with methylene blue. A skin flap of 6 cm × 3.4 cm, based on the first caudally directed cutaneous branch of the facial artery was shown to be well perfused. The viability of this flap was confirmed in a clinical case. The facial artery flap is useful for repair of skin defects of the head in cats.Veterinary Surgery 03/2011; 40(3):347-51. · 1.26 Impact Factor -
Article: Resolution of persistent pneumothorax by use of blood pleurodesis in a dog after surgical correction of a diaphragmatic hernia.
[show abstract] [hide abstract]
ABSTRACT: A 15-kg (33-lb) pregnant female mixed-breed dog of unknown age was referred because of a 10-day history of difficulty breathing. Physical examination findings were dyspnea, tachypnea, decreased bronchovesicular sounds (bilateral), muffled heart sounds, and abdominal distention with palpable fetuses. Hematologic abnormalities included anemia, leukocytosis, and thrombocytosis. Abnormalities detected during serum biochemical analysis included decreases in concentrations of albumin, sodium, triglycerides, and total calcium and increases in activities of alkaline phosphatase, alanine aminotransferase, gamma-glutamyltransferase, aspartate aminotransferase, lactate dehydrogenase, and creatine kinase. Thoracic radiography revealed a diaphragmatic hernia with fetuses and a soft tissue or fluid opacity within the thoracic cavity. Exploratory celiotomy, ovariohysterectomy, partial sternotomy, placement of a right-sided thoracostomy tube, and herniorrhaphy were performed. After surgery, pneumothorax developed, and the thoracostomy tube was used to remove pleural effusion and free air. The pneumothorax did not resolve after continuous drainage of the thoracic cavity for 4 days. Autologous blood pleurodesis was performed by infusion of 80 mL (6 mL/kg [2.73 mL/lb]) of whole blood. The pneumothorax resolved immediately after injection of the blood. Blood pleurodesis was used for resolution of pneumothorax in a dog after correction of a diaphragmatic hernia. Blood pleurodesis may provide a simple, safe, and inexpensive medical treatment for resolution of persistent (duration>5 days) pneumothorax when surgery is not an option.Journal of the American Veterinary Medical Association 08/2010; 237(3):299-303. · 1.79 Impact Factor -
Article: Agreement between values for arterial and end-tidal partial pressures of carbon dioxide in spontaneously breathing, critically ill dogs.
[show abstract] [hide abstract]
ABSTRACT: To determine agreement between arterial partial pressures of carbon dioxide (PaCO(2)) and end-tidal partial pressures of carbon dioxide (PETCO(2)) measured with a nasal catheter in spontaneously breathing, critically ill dogs. Validation study. 26 client-owned dogs admitted to an intensive care unit for various conditions. PaCO(2) was measured with a commercial blood gas analyzer, and PETCO(2) was measured with a sidestream capnograph attached to a nasal catheter. Measurements were obtained twice (ie, with and without supplemental oxygen). Paired values were compared by means of the Pearson correlation method. Level of agreement was assessed by means of the Bland-Altman method. Mean difference between PaCO(2) and PETCO(2) when dogs did not receive supplemental oxygen (mean +/- SD, 3.95 +/- 4.92 mm Hg) was significantly lower than mean difference when dogs did receive supplemental oxygen (6.87 +/- 6.42 mm Hg). Mean difference in dogs with a condition affecting the respiratory system (8.55 +/- 5.43 mm Hg) was significantly higher than mean difference in dogs without respiratory tract disease (3.28 +/- 3.23 mm Hg). There was a significant linear correlation and good agreement between measured values of PaCO(2) and PETCO(2). Catheter size, ventilatory status, and outcome were not significantly associated with mean difference between PaCO(2) and PETCO(2). Results suggested that nasal capnography is a clinically relevant method of estimating PaCO(2) in spontaneously breathing, critically ill dogs, but that values should be interpreted with caution in dogs receiving supplemental oxygen and in dogs with conditions affecting the respiratory system.Journal of the American Veterinary Medical Association 12/2009; 235(11):1314-8. · 1.79 Impact Factor
