Outpatient Midline Catheter in Patients Receiveing Lidocaine Infusion Series.

This study will assess the efficacy, safety and practicality of using midline catheters for repeated intravenous lidocaine infusions in an outpatient pain management setting. Adult patients requiring serial lidocaine infusions for chronic pain will be enrolled and receive treatment through midline catheters over ten sessions. The study will investigate if the midline catheters are a safe and effective option for delivering repeated lidocaine infusions in the outpatient setting, offering a balance between ease of placement, acceptable complication risk and good patients' comfort.
