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.

RECRUITINGSuccessful lidocaine infusion therapy without the need for additional venous access
Percentage of patients who received a daily lidocaine infusion for 10 days with a 2-day pause in an outpatient setting who did not require additional venous access.
Time frame: 12 days (from midline insertion to the end of the therapy)
Midline Catheter Maintenance Duration
The total duration (in days) that each patient maintains a functional midline catheter without premature removal.
Time frame: 12 days (from midline insertion to the end of the therapy)
Number of Participants with Premature Catheter Removal and Reasons
The primary reason for premature catheter removal will be documented, including: occlusion, inadvertent removal, extravasation, suspected infection, confirmed infection, thrombosis, catheter malfunction, phlebitis, or removal at the patient's request.
Time frame: 12 days (from midline insertion to the end of the therapy)
A-DIVA scale score
A scale used for the assessment of predicted difficulties in securing difficult intravenous access.
Time frame: The onset of therapy
Patient's satisfaction score
Patient satisfaction scores measured on a 0-10 scale
Time frame: 12 days (from midline insertion to the end of the therapy)
Number of catheter leakage events
Catheter leakage events is defined as leakage of blood or fluids from the puncture site.
Time frame: 12 days (from midline insertion to the end of the therapy)
Number of patients with phlebitis
Phlebitis is defined as infiltration/swelling or pain around the insertion site with medication or fluid administration
Time frame: 12 days (from midline insertion to the end of the therapy)
Total number of upper extremity deep venous thrombosis events
This is defined as symptomatic or asymptomatic DVT, verified by ultrasound or computed tomography. The total number of upper extremity DVT events will be recorded by study arm.
Time frame: 12 days (from midline insertion to the end of the therapy)
Number of patients who requested catheter removal
The number of patients who requested catheter removal due to discomfort or other reasons.
Time frame: 12 days (from midline insertion to the end of the therapy)
