RESUMO
An 8-year-old, spayed female Chihuahua mixed breed dog was presented for dyspnea and was subsequently mechanically ventilated. Propofol was utilized as part of the anesthetic protocol. The dog developed rhabdomyolysis, myoglobinuria, cardiac arrhythmias, liver enzyme elevation, and methemoglobinemia. Propofol was discontinued and N-acetylcysteine was administered after which the clinical signs resolved.
Syndrome s'apparentant à l'infusion de propofol chez un chien. Un chien Chihuaha mâle castré de race croisée âgé de 8 ans a été présenté pour de la dyspnée et a été subséquemment soumis à une ventilation mécanique. Le propofol a été utilisé dans le cadre du protocole anesthésique. Le chien a développé de la rhabdomyolyse, de la myoglobinurie, de l'arythmie cardiaque, une élévation des enzymes hépatiques et de la méthémoglobinémie. Le propofol a été discontinué et de la N-acétylcystéine a été administrée après la résolution des signes cliniques.(Traduit par Isabelle Vallières).

Arterial and venous blood gases provide useful information regarding pulmonary function as well as acid-base balance. The goal of this article is to discuss the collection of blood gases, common errors in analysis, and what information can be gleaned from a blood gas analysis.

OBJECTIVE: To compare the histopathologic diagnosis in dogs with spontaneous hemoperitoneum when abdominal ultrasonographic examination detects a solitary versus multiple lesions. DESIGN: Retrospective cross-sectional study. SETTING: Private veterinary hospital. ANIMALS: Client-owned dogs presented with spontaneous hemoperitoneum between March 1, 2003 and June 1, 2008. INTERVENTIONS: Dogs were divided into 2 groups based on presence of a solitary or multiple abdominal ultrasonographic lesions. Prevalences were compared between groups for malignancy and specifically hemangiosarcoma. MEASUREMENTS AND MAIN RESULTS: Ten of 31 (32%) dogs had a solitary abdominal ultrasonographic lesion and 21 of 31 (68%) had more than 1 lesion. The bleeding tissue was characterized as malignant in 8 of 10 (80%) dogs with solitary lesions and 17 of 21 (81%) dogs with multiple lesions; there was no significant difference (P=1.0) between groups. In this study no association (P=0.26) was found between the number of abdominal ultrasonographic lesions observed and subsequent diagnosis of hemangiosarcoma. CONCLUSIONS: Solitary abdominal ultrasonographic lesions in dogs with spontaneous hemoperitoneum do not necessarily indicate a lower prevalence of malignancy.
