Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 21 to 60 years with an ASA physical status of II or lower and a BMI under 35.

Probably not a fit

Patients who are over 60 years old, have a BMI of 35 or higher, or have contraindications to regional anesthesia will not benefit from this study.

What this trial studies

This clinical trial aims to compare the safety and efficacy of nylon (polyamide) epidural catheters versus polyurethane epidural catheters in patients undergoing major orthopedic surgery with continuous epidural anesthesia. It is a prospective, randomized, double-blind study involving 60 patients who will be randomly assigned to receive either type of catheter. The study will assess complications associated with catheter use, such as blockage, dysfunction, and breakage, to determine which material provides better outcomes for patients.

Why it matters

Potential benefit: If successful, this study could lead to improved safety and effectiveness of epidural anesthesia in orthopedic surgeries.

How similar studies have gone: While this study addresses a common issue in anesthesia, similar studies have not been widely reported, making this approach relatively novel.
