ClinConnect Summary

The HYP-NOR Trial is a clinical study that aims to find out if using noradrenaline, a medication that helps raise blood pressure, is more effective than standard methods in preventing low blood pressure (hypotension) during and after non-cardiac surgeries. This trial is important because maintaining stable blood pressure during surgery can help ensure better outcomes for patients.

To take part in this study, participants need to be at least 45 years old and scheduled for elective (planned) non-cardiac surgery that lasts at least an hour. They should also be expected to stay in the hospital overnight after the procedure. However, not everyone will qualify; individuals with certain health conditions, such as untreated high blood pressure or severe heart and kidney issues, will be excluded. If eligible, participants can expect to receive careful monitoring and treatment during their surgery to help manage their blood pressure. The study is currently not recruiting participants, but it hopes to provide valuable information about how to improve care during surgery in the future.

  • 3. Persistent atrial fibrillation
  • 4. Have a documented history of dementia
  • 5. Have language, vision, or hearing impairments that may compromise cognitive assessments
  • 6. Have a condition that precludes routine blood pressure management such as surgeon request for relative hypotension
  • 7. Receiving irreversible nonselective monoamine oxidase inhibitors (e.g. tranylcypromine, phenelzine) within 2 weeks preceding study enrolment
  • 8. The use of tricyclic antidepressants
