Summary
Venepuncture (VP) is less painful and more effective than heel lance (HL) for neonatal blood sampling. VP reduces the need for repeat punctures, making it the preferred method for term neonates.
Area of Science:
- Neonatal care
- Pain management in infants
- Pediatric phlebotomy
Background:
- Heel lance is the standard for neonatal blood sampling but causes pain.
- Existing interventions for heel lance pain are insufficient.
- Effective pain alleviation methods for neonates are needed.
Purpose of the Study:
- Compare pain and effectiveness of venepuncture versus heel lance in term neonates.
- Identify the optimal blood sampling method for neonatal screening.
Main Methods:
- Systematic review of randomized controlled trials (RCTs) comparing venepuncture and heel lance.
- Searched MEDLINE, EMBASE, CINAHL, and Cochrane Library.
- Analyzed pain response using validated scales (NIPS, NFCS, PIPP) and cry characteristics.
Main Results:
- Venepuncture showed statistically significantly lower pain scores than heel lance.
- Meta-analysis of NIPS scores revealed decreased pain in the venepuncture group.
- Venepuncture reduced the need for repeat skin punctures (NNT=3).
Conclusions:
- Venepuncture by skilled phlebotomists is the preferred method for neonatal blood sampling.
- Venepuncture is more effective, reducing repeat punctures.
- Further RCTs are needed to compare methods in diverse clinical settings.
