How long does spinal anesthesia last? A study in orthopedic surgery
Part of Bones, joints & muscles clinical trials.
This study tracks how long spinal anesthesia lasts during planned orthopedic surgeries. By collecting real-world data, doctors hope to improve timing and care for patients having this type of anesthesia.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for a planned (not emergency) orthopedic surgery that will use spinal anesthesia.
- Your health status is classified as ASA 1, 2, 3, or 4 (a rating used by your anesthesiologist).
- You are 18 years old or older.
- If you take blood thinners, they have been stopped following your doctor's guidelines.
- You do not have an infection or rash at the needle site in your lower back.
- You do not have a bleeding disorder and can stay still during the spinal injection.

This study looks at how non-medication factors—like body position, temperature, or movement—might change how long spinal anesthesia (numbing medicine injected into your spine) lasts during lower abdominal surgery. Understanding these factors could help doctors predict and optimize numbing for your procedure.
This study compares two ways of giving spinal anesthesia (midline vs. paramedian) using ultrasound guidance in adults having orthopedic surgery. The goal is to see which approach is safer and more effective.
This study compares two types of anesthesia for lower back surgery: one that uses opioids and one that does not. The goal is to see which approach controls pain better with fewer side effects.
This study compares two medicines (dexmedetomidine and fentanyl) added to a spinal numbing shot for people having planned leg or knee surgery. The goal is to see which one works better to keep your blood pressure stable, and to make the numbing last while keeping you comfortable.
This study compares two ways of giving spinal anesthesia (numbing medication in the back) for older adults having leg or hip surgery. It aims to see if adjusting the dose based on height works better than the standard fixed dose. If you are between 60 and 80 and having planned lower limb surgery, you may be eligible.
This study compares two types of anaesthesia for people with a weakened heart (ejection fraction between 35-40%) who need planned lower-limb surgery. It looks at how each method affects blood pressure and heart function during and after the procedure.
