Tambasco et al reported equations for estimating the insertion length of an umbilical vascular catheter. The authors are from Yale University.
Patient selection: neonate
Mobile app: UmbiCalc
Parameters:
(1) birthweight in grams
(2) arterial vs venous catheter

Insertion Length in centimeters

<= 1,500 g
|
arterial
|
(0.0047 * (weight)) + 7.38
|
|
<= 1,500 g
|
venous
|
(0.0026 * (weight)) + 4.35
|
|
> 1,500 g
|
arterial
|
(0.0017 * (weight)) + 11.85
|
|
> 1,500 g
|
venous
|
(0.0018 * (weight)) + 6.52

Performance:
• The arterial catheter length was correct in 90% of all patients.
• The venous catheter length was correct in 76% of all patients.
