Description

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.

Interventions

Ketorolac (Drug)
patients 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.
