Is this trial a fit for you?

Likely a good fit

Adults aged 40–90 undergoing elective TURP with ASA I–II and no contraindication to neuraxial anesthesia.

Probably not a fit

Patients with inadequate block, adverse reaction to the study drugs, or those requiring conversion to general anesthesia may not benefit.

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

What this trial studies

In this randomized, interventional trial, eligible adults undergoing elective TURP under neuraxial anesthesia are assigned to receive either a spinal anesthesia or a modified saddle block with hyperbaric bupivacaine at the L3-L4 level. Anesthesia level and hemodynamics are monitored closely, with hypotension treated as needed and any conversion to general anesthesia recorded. The trial aims to compare intraoperative stability and block adequacy between the two techniques. Participants are followed intraoperatively for blood pressure changes, heart rate, and requirement for intervention. Exclusion criteria include inadequate block and other standard contraindications to neuraxial anesthesia.

Why it matters

Potential benefit: If successful, the study could identify which neuraxial technique provides more stable blood pressure during TURP, potentially reducing complications.

How similar studies have gone: Previous work in neuraxial anesthesia for TURP has explored saddle block and spinal techniques, with mixed results; this study contributes new, direct comparison.
