Needle angle planning for paramedian spinal anesthesia

Official title: Paramedian Incidence Angles in Spinal Anaesthesia

Run by Consorci Sanitari de Terrassa · NCT07210892 · Data updated 2026-11-12

This project tests whether using ultrasound (and X‑ray when available) to estimate the best needle insertion angle can reduce the number of punctures and redirections for patients receiving spinal anesthesia.

Is this trial a fit for you?

Likely a good fit

Patients who are scheduled to receive spinal anesthesia at the participating center are the intended candidates for this project.

Probably not a fit

People not receiving spinal anesthesia, those in whom ultrasound or X‑ray cannot be obtained, or patients whose anatomy precludes angle-guided paramedian approach may not receive benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational project will record the number of needle punctures and redirections during routine spinal anesthesia and measure the actual angle of needle insertion. Ultrasound will be used to measure skin-to-dural sac distance and plain X‑ray distances will be correlated when available, while protractors or visual guides document insertion angles including paramedian approaches. Investigators will determine the optimal, maximum, and minimum angles that correspond with successful punctures and compare ultrasound versus X‑ray distance measurements. The team will also infer angles in advance for subsequent patients to see if prior estimation reduces the number of punctures and redirections.

Why it matters

Potential benefit: If successful, this approach could reduce needle punctures and redirections, lowering pain and complication risk and shortening procedure time.

How similar studies have gone: Previous studies show ultrasound guidance can reduce needle attempts for spinal anesthesia, but detailed mapping of paramedian insertion angles and routine preprocedure angle estimation is less well studied.
