Brief summary
This prospective randomized controlled trial aims to compare basilic vein and cephalic vein approaches for midline catheter placement in pediatric patients undergoing general anesthesia. Participants aged 2 to 17 years who require midline catheter insertion will be randomly assigned 1:1 to either the basilic vein group or the cephalic vein group. The primary outcome is the clinical blood sampling success rate during the catheter dwell period, defined as successful aspiration of ≥2 mL of blood through the midline catheter at least once without additional venipuncture. Secondary outcomes include operator-rated difficulty, number of puncture attempts, first attempt cannulation success rate, vein diameter and depth, catheter dwell time, catheter-related complications, and patient satisfaction. A total of 96 participants (48 per arm) will be enrolled at Seoul National University Children's Hospital.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical blood sampling success rate during catheter dwell period | From catheter insertion until catheter removal (up to 7 days postoperatively) | Clinical blood sampling success rate during catheter dwell period - defined as successful aspiration of ≥2 mL of blood through the midline catheter for clinically indicated laboratory testing at least once during the dwell period, without additional venipuncture (%) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Operator-rated difficulty score | At time of catheter insertion | Operator-rated difficulty of midline catheterization assessed on a numerical rating scale (0-10; 0=very easy, 10=extremely difficult) |
| Number of puncture attempts | At time of catheter insertion | Total number of needle puncture attempts required for successful midline catheter placement |
| First attempt cannulation success rate | At time of catheter insertion | Proportion of participants in whom the midline catheter was successfully placed on the first puncture attempt (%) |
| Standardized blood aspiration success | Intraoperatively and postoperative day 1 | Success of blood aspiration through the midline catheter using a standardized protocol (≥2 mL), assessed intraoperatively and on postoperative day 1 |
| Allocated vein diameter and depth | At time of catheter insertion | Diameter (mm) and depth (mm) of the allocated vein (basilic or cephalic) measured by ultrasound before and after catheter placement |
| Catheter dwell time | From catheter insertion until catheter removal (up to 7 days postoperatively) | Duration from catheter insertion to catheter removal (days) |
| Catheter-related complications | From catheter insertion until catheter removal (up to 7 days postoperatively) | Incidence of catheter-related complications including hematoma, bleeding, infection, and thrombosis |
| Patient satisfaction score | At catheter removal (up to 7 days postoperatively) | Patient or caregiver satisfaction with the midline catheter assessed on a numerical rating scale (0-10; 0=very dissatisfied, 10=very satisfied) |
