Low neck puncture leaves more catheter to curve in the neck; mid-neck puncture creates lax catheter that can lead to problems with neck turning and catheter displacement from the SVC. — Alex Bondoc, Pediatric Vascular Access in Brief: Preoperative, Operative, and Postoperative Considerations · 6:22

Pediatric Vascular Access in Brief: Preoperative, Operative, and Postoperative Considerations
In the United States, approximately 5 million central venous catheter lines are placed annually, with several thousand in pediatric surgical patients.
At Cincinnati Children's Hospital, the transplant surgery team manages complex vascular access and catheter-based dialysis access.
Alex Bondoc0:26
Central venous catheters are non-tunneled, typically for temporary hospital use, and can have 1 to 3 lumens.
Ports are for long-term access (months to years), have tunneled catheters with totally implantable reservoirs, are often used for chemotherapy, and can have 1 or 2 lumens.
Broviac catheters are tunneled lines with cuffs, used for months to years for chemotherapy, parenteral nutrition, or frequent blood transfusions, and can have 1 or 2 lumens.
Hemodialysis or pheresis catheters can be temporary (uncuffed) or permanent (cuffed), and can have 1 to 3 lumens.
From a logistical standpoint, chest and neck central venous access is preferred over femoral access.
Alex Bondoc2:09
There is evidence suggesting an increased rate of complications and infection with femoral access compared to chest and neck access.
Contraindications for central venous access include thrombosis, collateralization, and central stenosis of the SVC, which may require exotic concurrent procedures or alternative access sites.
Alex Bondoc2:39
Unless patients have congenital anomalies (usually cardiovascular), routine pre-procedural ultrasound is not necessary for first-time line placement.
Alex Bondoc3:09
For patients requiring multiple lines (line number 4, 5, or 6), Doppler venous ultrasound of the jugulars is recommended, and in small children the SVC and subclavians can sometimes be visualized.
Alex Bondoc3:20
Pre-procedural imaging may be escalated to contrast-enhanced MR or CT venography, and sometimes intraoperative venography with fluoroscopy is performed.
Alex Bondoc3:37
For small children, neonates, and infants, positioning over a vertically oriented shoulder roll (parallel with the spine) provides hyperextension of the neck and allows shoulder weight to drop posteriorly, giving access to bilateral subclavians and jugulars.
Alex Bondoc3:59
For very small neonates, many surgeons prefer a cut-down approach over percutaneous access.
Dr. Bonddo prefers using a micropuncture kit with a 21-gauge finder needle for small babies, which is smaller than the 18-gauge needle in standard tunnel line kits.
Alex Bondoc4:55
Using ultrasound for internal jugular central line placement is the number one preferred method, with the lowest risk of pneumothorax and carotid artery injury.
Alex Bondoc5:25
For large-bore access like dialysis catheters, the patient should be stuck as low as possible on the neck, using the ultrasound probe (approximately 12mm diameter) levered against the clavicle as a landmark.
Alex Bondoc5:52
Low neck puncture leaves more catheter to curve in the neck; mid-neck puncture creates lax catheter that can lead to problems with neck turning and catheter displacement from the SVC.
Alex Bondoc6:22
Subclavian line placement should be considered when both IJ access sites are lost or the patient is in a cervical collar.
For subclavian access, the insertion point is at the junction of the median and medial aspects of the clavicle, at least one finger breadth (approximately 1cm) inferiorly and laterally, to allow levering under the bone.
Alex Bondoc6:56
When approaching the clavicle during subclavian access, the needle should be kept flat with downward pressure on the skin rather than angling at 30 degrees.
Alex Bondoc7:14
For subclavian access, the needle should be aimed directly at the sternal notch initially, then angled wider toward the angle of the mandible in a radial motion if unsuccessful.
Alex Bondoc7:34
The catheter tip should typically be positioned at the junction between the right atrium and superior vena cava.
The right triangle technique for catheter tip positioning uses the trachea as the theoretical midline continued from the carina, with the right main stem bronchus as the hypotenuse; the catheter tip should be within this triangle to ensure atriocaval junction placement.
Alex Bondoc8:04
Post-procedural chest X-ray is not routinely ordered for single-stick, uncomplicated line placement using fluoroscopy, based on data from Children's Mercy Hospital Kansas City.
Alex Bondoc8:38
Post-procedural complications include pneumothorax, hemothorax, arterial injury (subclavian or carotid), and rare complications like chylothorax or thoracic duct injury.
Alex Bondoc9:06
Long-term complications include thrombosis, catheter displacement, kinking, and eventual line degradation over extended periods.
For line infection management, the first clinical decision is whether the patient is septic from the line; if septic and in the ICU, source control requires bedside line removal under light sedation.
Alex Bondoc9:41
For non-septic line-dependent patients with complex vascular access, the organism and antibiotic sensitivity are determined, serial blood cultures are obtained, and the line may be salvaged if sustained culture negativity is achieved.
Alex Bondoc10:04
Traditional locking solutions are predominantly antibiotic locks, but they lead to development of bacterial resistance.
