Alpha blockers' effects on blood pressure during spinal anesthesia
Part of Heart & circulation clinical trials.
This trial looks at how alpha blockers (a type of medicine that relaxes blood vessels) affect blood pressure and heart function in people having spinal anesthesia for planned urologic surgery. It aims to help doctors manage anesthesia more safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are scheduled for planned urologic surgery that uses spinal anesthesia (numbing medicine injected into your back).
- Your physical health is rated as ASA I, II, or III (a standard way doctors classify surgical risk).
- You are not currently taking any alpha-blocker medication (a type of blood pressure or prostate medicine).
- You do not have a history of heart disease, brain or spinal cord conditions, or neurological/psychiatric disorders.

This trial tests if a medicine taken before surgery can help prevent low blood pressure caused by spinal anesthesia. It is for people having planned leg or plastic surgeries.
This study compares how a common numbing medication (bupivacaine) affects your heart rate and blood pressure when given as a spinal injection before surgery. Researchers want to understand these effects better to keep patients safer during procedures.
This study compares two types of anesthesia—spinal (numbing the lower body) versus general (putting you to sleep)—for men having prostate surgery to treat benign enlargement. The goal is to see which approach works better and is safer for this procedure.
This study looks at a new way to predict if your blood pressure will drop during spinal anesthesia for hernia surgery. It may help doctors prevent dizziness or fainting during the procedure.
This study tests if giving hydrocortisone (a type of steroid) or ondansetron (an anti-nausea drug) before spinal anesthesia can better prevent low blood pressure during surgery for your belly or lower leg.
This study looks at whether how anxious you feel before surgery affects your risk of a sudden drop in heart rate and blood pressure (vasovagal event) when you receive spinal anesthesia. Participation may help doctors better understand and prevent these episodes.
