Question 1

MEDIUM

A 7-year-old male neutered Labrador Retriever is presented for acute onset weakness and collapse after exercise. Physical exam shows pale mucous membranes, tachycardia, and a distended abdomen with a fluid wave. Point-of-care ultrasound reveals free abdominal fluid and a large, cavitated splenic mass. Abdominocentesis yields nonclotting blood with a PCV similar to peripheral blood. Which of the following is the most appropriate next step to stabilize this patient prior to surgery?

This dog is in hypovolemic shock from hemoabdomen secondary to a likely splenic tumor (e.g., hemangiosarcoma). Stabilization includes oxygen, large-bore IV access, judicious crystalloid boluses, and blood product support. Type and crossmatch and transfuse packed RBCs (and consider plasma if coagulopathy) based on perfusion parameters and PCV/TS trends. Immediate surgery without stabilization increases anesthetic risk; diuretics, steroids, antibiotics, and mannitol are not primary stabilization measures for hemorrhagic shock.
