Summary

This multicenter, randomized, double-blind, placebo-controlled trial evaluates the efficacy and safety of ketorolac in 360 patients with Stanford Type A aortic dissection, conducted between 2025 and 2027. Participants will receive either ketorolac (60 mg intramuscularly \[IM\] preoperatively and 30 mg twice daily \[BID\] 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.

Detailed description

This multicenter, randomized, double-blind, controlled clinical trial will enroll 360 eligible patients with Stanford Type A aortic dissection between March 2025 and December 2027. Participants will be equally randomized to receive either ketorolac (intervention group: 60 mg intramuscular \[IM\] preoperatively followed by 30 mg twice daily \[BID\] for two days postoperatively) or matching placebo (control group), with both groups receiving standard perioperative care including analgesia, blood pressure control, and surgical treatment. Comprehensive data collection will include demographic characteristics, clinical parameters, laboratory tests (complete blood count \[CBC\], biochemistry, coagulation profile, cardiac enzymes, procalcitonin, cultures), and imaging studies (radiomics, biomechanics, chest X-ray, ultrasound, computed tomography \[CT\], magnetic resonance imaging \[MRI\]) at multiple timepoints from admission through 90-day follow-up. The primary outcomes will focus on evaluating the efficacy and safety of ketorolac through analysis of composite endpoint events, complication rates, and adverse reactions, with immediate study discontinuation and reporting for any treatment-related adverse events. All treatment protocols will maintain identical administration schedules and formulations between groups, with the exception of the active drug versus placebo.
