Venepuncture probably reduced pain and repeat punctures versus heel lance in term newborns without sweet solutions

Brief summary

An updated Cochrane review of eight randomized or quasi-randomized studies involving 826 term neonates found moderate-certainty evidence that venepuncture probably reduced procedural pain and repeat punctures versus heel lance when no sweet-tasting analgesic solution was used.

What NurseJet pulled from the source

This Cochrane review update compared venepuncture with heel lance for blood sampling in term neonates. Eight randomized or quasi-randomized studies with 826 infants were included, and overall risk of bias was judged high. Without a sweet-tasting solution, venepuncture probably reduced pain and the need for more than one puncture, based on moderate-certainty evidence. With a sweet-tasting solution, venepuncture may reduce pain, but evidence was low certainty, and the effect on repeat punctures was very uncertain. The findings depend on the analgesia context and do not replace neonatal sampling competency or pain-management protocols.

Why this matters for nurses

Pediatric and newborn nurses perform or support frequent blood sampling and assess procedural pain. This review distinguishes the evidence by sampling method and whether a sweet-tasting analgesic solution is used.

Bedside takeaway

Venepuncture probably reduced pain and repeat punctures without sweet solutions, but the evidence changes when analgesic solutions are used.

How This Applies in Practice

Use this when: Preparing to obtain a provider-ordered blood sample from a term neonate.

On your shift

  • Confirm the approved collection method and pain-management plan and ensure the clinician performing the procedure has the required competency.
  • Assess procedural pain, record the number of punctures, and escalate repeated unsuccessful attempts through the unit pathway.
Keep in mind: Do not choose a sampling or analgesia method from this review alone. Follow the neonatal protocol, facility policy, and patient-specific provider orders.

Key takeaways

  • The updated Cochrane review included eight studies and 826 term neonates.
  • Without a sweet-tasting solution, venepuncture probably reduced pain and repeat punctures versus heel lance.
  • With a sweet-tasting solution, pain evidence was low certainty and repeat-puncture evidence was very uncertain.
  • All eight studies had an overall high risk of bias, particularly around blinding and allocation concealment.

Practice implications

  • Before collecting a term newborn's sample, confirm the ordered test, approved collection method, staff competency, and neonatal pain-management plan. Use a validated pain assessment and document the number of punctures; escalate repeated unsuccessful attempts according to the unit pathway.

Limitations & cautions

  • The eight included studies had an overall high risk of bias and substantial pain-score heterogeneity. Evidence with sweet-tasting solutions was low or very low certainty, and the repeat-puncture estimate in that context was based on only 110 infants with a very wide confidence interval.
