# Comparing Basilic and Cephalic Vein Approaches for Midline Catheter Placement in Children

**Official Title:** Comparing Basilic and Cephalic Vein Approaches for Midline Catheter Placement in Children: A Randomized Controlled Trial

**NCT ID:** [NCT07509359](https://clinicaltrials.gov/study/NCT07509359)

## Key Facts

- **Status:** RECRUITING
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 96
- **Lead Sponsor:** Seoul National University Hospital
- **Conditions:** Vascular Access Device Complications
- **Start Date:** 2026-04-01
- **Completion Date:** 2030-04-01
- **CT.gov Last Update:** 2026-04-03

## 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.

## Eligibility

- **Minimum age:** 2 Years
- **Maximum age:** 17 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
Inclusion Criteria:

* Age 2-17 years undergoing general anesthesia
* Midline catheter placement deemed necessary by attending anesthesiologist (≥1 of: expected ≥2 postop blood draws; expected blood loss ≥40% EBV; continuous antibiotic therapy; hospitalization ≥7 days; surgical team request)

Exclusion Criteria:

* Need for central venous catheter per surgical team
* Coagulopathy
* History of severe thrombosis
* Other investigator-determined ineligibility
```

## Arms

- **Basilic Vein Group** (ACTIVE_COMPARATOR)
- **Cephalic Vein Group** (EXPERIMENTAL)

## Interventions

- **Midline catheter placement via basilic vein** (PROCEDURE) — Midline catheter placement via basilic vein under ultrasound guidance
- **Midline catheter placement via cephalic vein** (PROCEDURE) — Midline catheter placement via cephalic vein under ultrasound guidance

## Primary Outcomes

- **Clinical blood sampling success rate during catheter dwell period** _(time frame: 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 Outcomes

- **Operator-rated difficulty score** _(time frame: At time of catheter insertion)_
- **Number of puncture attempts** _(time frame: At time of catheter insertion)_
- **First attempt cannulation success rate** _(time frame: At time of catheter insertion)_
- **Standardized blood aspiration success** _(time frame: Intraoperatively and postoperative day 1)_
- **Allocated vein diameter and depth** _(time frame: At time of catheter insertion)_
- **Catheter dwell time** _(time frame: From catheter insertion until catheter removal (up to 7 days postoperatively))_
- **Catheter-related complications** _(time frame: From catheter insertion until catheter removal (up to 7 days postoperatively))_
- **Patient satisfaction score** _(time frame: At catheter removal (up to 7 days postoperatively))_
