Intervention

Infants were allocated to venipuncture (VP) with a 0.9 × 40 mm microlance needle (n=50), heel lance with a small lancet (SL) (n=50), or heel lance with a large lancet (LL) (n=20). Before the VP, the dorsum of the hand was gently squeezed to visualise the vein. The SL was placed on the skin, and when pressure was applied to the end of the device a 2 mm lancet penetrated the skin. The LL required hand power to penetrate the skin with a sharp triangular edge of 2.5 mm. All infants were fed 1–2 hours before testing and were sleeping lightly or resting quietly when testing began. …
