Ibuprofen pretreatment does not prevent hemodynamic instability after cemented arthroplasty in dogs

A bilateral cemented arthroplasty (BCA) in anesthetized mongrel dogs creates pulmonary fat and marrow embolism. A transient increase in plasma concentration of 6-keto prostaglandin F 1α and thromboxane B 2 has been associated with hemodynamic instability after BCA. We tested whether intravenous ibuprofen (20 mg/kg) could inhibit prostaglandin production, pulmonary hypertension, and decreased arterial blood pressure in this model
