Managing high blood pressure before anesthesia for safer surgery

This trial tests a blood pressure medicine called clevidipine given through an IV to people with a brain bleed (intracerebral hemorrhage). The goal is to see if quickly lowering blood pressure helps prevent more bleeding and improve recovery.

This trial tests how doctors manage blood pressure during major surgery using common medicines (norepinephrine or phenylephrine). It may help by improving safety for people at higher risk of blood pressure drops or complications during surgery.

This study tests whether personalized blood pressure management during and after major surgery can reduce complications and death in older adults with heart or blood vessel risks. It aims to find the safest blood pressure targets for each patient.

This trial tests whether noradrenaline is better than standard care for preventing dangerously low blood pressure during surgery. If you are having non-cardiac surgery that lasts at least an hour and are expected to stay overnight, this study may be for you.

This study looks at how blood pressure medications affect low blood pressure episodes that happen during and after heart surgery. Researchers want to understand if the number of blood pressure drugs you take before surgery changes how your body handles blood pressure during the operation.

This study tests two medicines given before surgery to see which one better controls blood pressure and heart rate during the start of anesthesia. It may help people with high blood pressure have a safer and smoother experience when they are put to sleep for surgery.
