This multicenter, randomized, double-blind, placebo-controlled trial evaluates the efficacy and safety of ketorolac in 1,346 patients with Stanford Type A aortic dissection, conducted between 2025 and 2028. Participants will receive either ketorolac (60 mg intramuscularly \[IM\] within 6 hours before surgery and 30 mg im twice daily（at 6:00 AM and 6:00 PM, respectively for two days postoperatively or placebo in addition to standard care. Study outcomes include composite clinical endpoints, postoperative complications, and adverse events, which will be assessed through clinical evaluations, laboratory testing, and imaging studies at predefined intervals up to 90 days. The objective of this trial is to determine whether perioperative administration of ketorolac improves clinical outcomes in this patient population.

Ketorolac
Drugpatients in the experimental group will receive ketorolac treatment for Stanford Type A aortic dissection, consisting of a 60mg intramuscular injection within 6 hours before surgery followed by 30mg im twice daily(at 6:00 AM and 6:00 PM, respectively )for two days postoperatively, while maintaining standard baseline therapies including analgesia, blood pressure control, and subsequent cardiovascular surgical management.

Primary endpoints
In-hospital mortality and the occurrence of organ malperfusion syndrome (including myocardial ischemia, stroke, lower limb paralysis, acute abdominal pain, renal failure requiring temporary dialysis, or limb ischemia) during the hospitalization.
erythrocyte sedimentation rate (ESR)
erythrocyte sedimentation rate (ESR), an indicator of systemic inflammation that reflects the rate at which red blood cells settle in a vertical tube over a specified period. Elevated ESR levels may suggest ongoing inflammatory responses, infection, or tissue injury
The perioperative use of opioids
The perioperative use of opioids such as fentanyl and remifentanil is also assessed
C-reactive protein (CRP)
C-reactive protein (CRP), an acute-phase protein synthesized by the liver that rises rapidly in response to infection, inflammation, or tissue injury. CRP serves as a sensitive biomarker of systemic inflammatory response and will be used to assess the perioperative inflammatory status in patients with Stanford Type A aortic dissection.
interleukin-6 (IL-6)
interleukin-6 (IL-6), a pro-inflammatory cytokine produced by various cells in response to tissue injury, infection, or stress. IL-6 plays a key role in the acute-phase inflammatory response and is closely associated with the severity of systemic inflammation.
