What lancet size is recommended for use on premature babies?

The recommended lancet size for use on premature babies is 1.0mm, which is indicated by the green lancet. This size is considered optimal because it is small enough to minimize trauma to the delicate skin of premature infants, while still being effective in obtaining a sufficient blood sample for testing. Premature babies have thinner skin and are more vulnerable, so using an appropriate lancet size is crucial to avoid excessive pain or injury.

Using a lancet that is too large, such as 1.5mm or 2.0mm, could cause unnecessary discomfort and potential complications due to the depth of the puncture. In contrast, a lancet that is too small might not provide enough blood for testing, leading to inadequate sample collection. Hence, the 1.0mm green lancet strikes the right balance for safely performing capillary blood draws on premature infants.
