Umbilical vein catheterization
- Emergency access and stabilization of the newly born with lack of peripheral access
- Remains viable and patent until ~1 week after birth
- Fluid chamber, IV tubing, infusion pump, filter (0.22 µm), short length of IV tubing, three-way stopcock
- Umbilical catheter (3.5 to 5 Fr)
- 3-0 silk suture on a curved needle
- Curved iris forceps without teeth
- Small clamps, forceps, scissors, needle holder
- 10 mL of heparinized solution for flush (1–2 units heparin per milliliter of fluid)
- Sterile drapes, surgical cap, mask, gown, and gloves
- Place patient under warmer
- Hold umbilical stump and scrub with betadine (avoid pooling at patient's sides secondary to to blistering under warmer
- Drape in sterile fashion (leave head exposed for observation)
- Flush catheter (3.5 Fr for preterm to 5 Fr for term newborns and attach to three-way stopcock)
- If emergency and UVC kit not available, consider 3.5 Fr ≈ 18.5 gauge and 5 Fr ≈ 16 ga
- Grab long angiocaths and remove from needle in sterile fashion
- Place purse string suture or umbilical tape at jct of skin and cord to provide hemostasis and to secure line
- Cut cord with scalpel 1 cm from skin
- Identify the vein (larger, thin walled vessel usually at 12 o'clock position that continues to bleed. usu 2 arteries, 1 vein)
- Feed the "mouth"
- Gently dilate catheter with forceps, clearing thrombus
- Gently advance catheter until blood returns and then advance 1-2 cm more (usually a total of 4-5 cm in term infant)
- Secure the catheter using the purse string or umbilical tape and then secure to the patient
- The catheter can be advanced to the IVC using a standardized graph, if CVP monitoring or high concentrations of glucose are indicated
- Confirm catheter location radiographically
- Travels cephalad until passing through ductus venosus
- In contrast, umbilical arterial catheters travel down into iliac arteries and then cephalad
- Hepatic necrosis (secondary to to injection of sclerosing solutions)
- Air embolism (especially on removal of catheter)
- Catheter tip embolism
- Vessel perforation
Vascular access types
- Central venous catheterization
- Rapid infusion catheter
- Intraosseous access
- Venous cutdown
- Umbilical vein catheterization
- Ultrasound assisted peripheral line placement
- External jugular vein cannulation
- The "Easy IJ"
