Official title: Ultrasound-assisted Spinal Anesthesia in Midline Versus Paramedian Approach in Adult Orthopedic Surgery
Run by Sohag University · NCT07047469 · Data updated 2026-11-12
This will test whether ultrasound-guided midline or paramedian spinal anesthesia requires fewer needle passes in adults 18–50 having orthopedic surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–50 undergoing orthopedic surgery who are ASA I–II, have BMI <30, and have no spinal deformities or contraindications to spinal anesthesia.
✕Probably not a fit
Older adults, obese patients (BMI ≥30), and those with prior spinal surgery, spinal deformity, coagulopathy, active infection, or other contraindications are excluded and unlikely to benefit from this protocol.

What this trial studies
This randomized interventional comparison enrolls adults aged 18–50, ASA physical status I–II, with BMI under 30 who are scheduled for orthopedic surgery at Sohag University Hospital. Participants receive ultrasound-guided spinal anesthesia using either a midline or a paramedian needle approach, and the primary outcome is the number of needle passes to successful dural puncture. The protocol records procedure-related measures such as time, patient discomfort, and any complications. Patients with prior spinal surgery, spinal deformity, coagulopathy, infection, obesity, or other contraindications to spinal anesthesia are excluded.
Why it matters
Potential benefit: If successful, the preferred approach could reduce needle passes, lower patient discomfort, and decrease procedure-related complications.
How similar studies have gone: Previous studies indicate ultrasound guidance can reduce needle passes and improve first-attempt success for spinal anesthesia, though direct comparisons between midline and paramedian ultrasound-guided approaches are limited.
