What this trial studies

This pilot clinical trial aims to assess the feasibility of conducting a larger randomized controlled trial on the use of ropivacaine for spinal anesthesia in patients undergoing elective lower spine surgery. The study will evaluate eligibility rates, recruitment, consent, and attrition, as well as the acceptability of spinal anesthesia among patients and healthcare providers. Participants will be randomly assigned to receive either general anesthesia, spinal anesthesia with bupivacaine, or spinal anesthesia with ropivacaine. Preliminary data on relevant outcomes will also be collected to inform future studies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older scheduled for elective one or two-level lumbar surgery.

Not a fit: Patients with allergies to ropivacaine or bupivacaine, or those with contraindications to spinal anesthesia will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and recovery outcomes for patients undergoing lower back surgery.

How similar studies have performed: While the specific use of ropivacaine in this context is novel, similar studies on spinal anesthesia have shown promising results.
