The Effects of Manual and Automatic Lancets on Neonatal Capillary Heel Blood Sampling Pain: A Prospective Randomized Controlled Trial

Effects of automatic heel lancet on invasiveness in neonates: A systematic review and meta-analysis

AIM

We conducted a meta-analysis comparing the invasiveness of automatic lancet devices, which can collect adequate amount of blood at shallow puncture depths, with conventional manual lance devices (lancet or needle) to statistically identify less invasive instruments for neonatal heel lance.

METHODS

We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, and Ichushi databases for studies comparing the invasiveness between automatic lancet and manual lancet or needle in term and preterm neonates in neonatal intensive care unit.

RESULTS

This review included 9 out of 449 searched articles, with 673 neonates. Automatic lancet had significantly lower pain scores (standardised mean difference: -2.0, 95% confidence interval: -3.3 to -0.7), heart rate (mean difference: -8.0, 95% confidence interval: -13.8 to -2.1), cry duration (mean difference: -21.5, 95% confidence interval: -32.5 to -10.4), number of punctures (mean difference: -0.6, 95% confidence interval: -1.1 to -0.2), and duration of procedures (mean difference: -37.7, 95% confidence interval: -75.2 to -0.2) than manual lancet or needle. Furthermore, peripheral oxygen saturation was significantly higher in automatic lancet than in manual lancet or needle (mean difference: 4.5, 95% confidence interval: 0.5-8.5).

CONCLUSION

Automatic heel lancet devices were less invasive than manual heel lance devices (lancet or needle).

Analgesic utility of automatic lancing device for heel prick in neonates: a systematic review and meta-analysis

Background: This systematic review and meta-analysis assessed the benefits of an automatic lancing device compared with a manual lancet or a hypodermic needle in neonates.Materials & methods: We followed the Cochrane Handbook methodology, used the RoB-2 tool for risk of bias assessment, RevMan 4.1 for meta-analysis and GRADE framework for certainty assessment. We searched the databases and gray literature on 15 November 2023.Results: Six eligible studies enrolling 539 neonates were included. An automatic lancing device reduced pain scores during and after heel prick, sampling time and the need for repeat puncture. The certainty of evidence was very low to moderate.Conclusion: An automatic lancing device is preferred for heel pricks in neonates, given less pain and higher efficiency.PROSPERO registration number: CRD42023483189.

Minimally invasive capillary blood sampling methods

INTRODUCTION

Whole blood samples, including arterial, venous, and capillary blood, are regularly used for disease diagnosis and monitoring. The global Covid-19 pandemic has highlighted the need for a more resilient screening capacity. Minimally invasive sampling techniques, such as capillary blood sampling, are routinely used for point of care testing in the home healthcare setting and clinical settings such as the Intensive Care Unit with less pain and wounding than conventional venepuncture.

AREAS COVERED

In this manuscript, we aim to provide a overview of state-of-the-art of techniques for obtaining samples of capillary blood. We first review both established and novel methods for releasing blood from capillaries in the skin. Next, we provide a comparison of different capillary blood sampling methods based on their mechanism, testing site, puncture size, cost, wound geometry, healing, and perceptions of pain. Finally, we overview established and new methods for enhancing capillary blood collection.

EXPERT OPINION

We expect that microneedles will prove to be a preferred option for paediatric blood collection. The ability of microneedles to collect a capillary blood sample without pain will improve paediatric healthcare outcomes. Jet injection may prove to be a useful method for facilitating both blood collection and drug delivery.

Effects of mother-sung lullabies on vaccination-induced infant pain and maternal anxiety: A randomized controlled trial

PURPOSE

This study aimed to investigate the effects of mother-sung lullabies during vaccination on vaccine-induced pain in infants and anxiety in mothers.

DESIGN AND METHODS

Our team conducted a randomized controlled trial with two parallel groups between March 4, 2020 and August 28, 2020, at two family health centers in Turkey. This study included 60 healthy-term infants (lullaby group: 30, control group: 30) aged two months, who received the Bacillus Calmette-Guérin (BCG) vaccine, and their mothers. We used the Information Form, the Neonatal Infant Pain Scale, the Intervention Follow-Up Form (including heart rate, oxygen saturation, and crying duration), and the State Anxiety Inventory as data collection tools.

RESULTS

Infants in the lullaby group had significantly decreased pain responses than those in the control group (p < .05). Further, singing a lullaby resulted in significantly reduced maternal anxiety in the lullaby group compared to the control group (p < .05).

CONCLUSIONS

The lullaby singing method was effective for reducing infants' pain response and mothers' anxiety during vaccination.

PRACTICE IMPLICATIONS

The lullaby method can be used to reduce pain during potentially painful procedures performed in infants and reduce anxiety in mothers. The study is registered under the ClinicalTrials.gov identifier NCT04692584.
