“Arterialization” of the venous blood for the blood gas analysis

Can you achieve “arterialization” of the venous blood in a dog with normal cardiovascular status by heating its paw to 37C (=98.6F) for measurement of blood gas variables?

In both human and veterinary medicine, venous blood samples have been used to estimate acid-base balance as an alternative to arterial blood samples. In human medicine, a technique called “arterialization” of the dorsal hand vein is established, where warming the hands to 42-43°C (=107-109.4F) for 10-15 minutes makes venous blood more similar to arterial blood.

Antiemetics in pets with foreign body obstruction

Does administration of antiemetic medications to dogs and cats with gastrointestinal foreign body obstruction delay time to definitive care (surgery or endoscopy) and increases the risk of complications?

Puzio et al., JVECC 2023 (Blue Pearl, Wisconsin, USA) performed a retrospective study on 440 dogs and 97 cats to answer this question. The study found that, while antiemetic administration prolonged the time from clinical signs to definitive care (3.2 days vs. 1.6 days; P < 0.001), it did not significantly increase the risk of complications related to foreign body obstruction. However, the use of antiemetics was associated with a longer hospitalization period (1.6 days vs. 1.1 days; P < 0.001). The study suggests that antiemetics are not inherently contraindicated in gastrointestinal foreign body obstruction cases, but veterinarians should advise clients to closely monitor their pets for symptom progression and seek follow-up care accordingly.

From Novice to Expert: How to Master Small Animal Electrolyte and Acid-Base Disorders?

For emergency veterinarians, interns and residents, ECC and anesthesia technicians seeking to truly master emergency and critical care topics, traditional continuing education (CE) courses, webinars, and lectures may prove to be inadequate. These conventional methods often fall short in several key aspects, hindering effective learning and retention. Over the last 15 years, I have attended dozens of CE events and watched hundreds of hours of webinars, only to realize a week later that I can recall 5-10% of this information. Have you ever felt that way?

Breathing Patterns: All Eyes On That Chest

Stress-free examination of a dyspneic patient is key. A lot of information can be gathered just from observing a dyspneic animal. Assessment of the movement of the chest and abdominal wall relative to one another alongside breathing rate and effort can help refine your differentials and streamline your emergency diagnostics and emergency management.

Can both prolonged PT/PTT and shortened PT/PTT be indicative of a prothrombotic state?

In the field of veterinary medicine, standard clotting tests like prothrombin time (PT) and partial thromboplastin time (PTT) have traditionally been used to diagnose hypocoagulability, or a decreased ability of the blood to clot. However, recent research has raised the question of whether both prolonged and shortened PT/PTT can actually be indicative of hypercoagulability, a state where there is an increased tendency for blood clot formation.
