Scenario
A 25-week gestation preterm infant is admitted to the neonatal intensive care unit. She has been intubated and ventilated for 7 days, the umbilical artery catheter has been removed since her umbilical cord has fallen and she needs frequent blood gases. A senior nurse asked about the technique of capillary blood gas, and she wondered why don’t we use the centre of the heel?
Structured clinical question
In term and preterm neonates (patient), is lancing the centre of the heel (intervention) if compared with lateral and medial aspects for blood sampling, associated with bone or cartilage infection (outcome)?
