Lin et al reported a method for determining the insertion length of an umbilical artery catheter in an Asian infant.
Target insertion: tip located between vertebral levels T7 and T11
Body Weight in Grams
Catheter Length
1,000 to 1,249
10 cm
1,250 to 1,499
11 cm
1,500 to 1,749
12 cm
1,750 to 1,999
13 cm
2,000 to 2,249
14 cm
>= 2,250
15 cm
length of catheter in cm =
= 10 + MIN(INT(((weight) - 1000) / 250),5)
Performance:
• About 96% of infants had the catheter tip at the target level.
