Neonatal pain: A journey spanning three decades

Effect of Non-Pharmacological Methods in the Reduction of Neonatal Pain: Systematic Review and Meta-Analysis

In neonatology, neonates have traditionally been considered incapable of feeling pain, due to the immaturity of their nervous system. Currently, there is sufficient information on the perception of pain in neonates; however, this treatment at this crucial stage for development requires a better approach. For this reason, the aim of this study was to analyse the efficacy of non-pharmacological analgesia interventions during heel prick, and to assess their effects on heart rate (HR), premature infant pain profile (PIPP) and O2 saturation. A systematic review and meta-analysis was performed following the guidelines of the preferred reporting items for systematic reviews and meta-analyses (PRISMA), and the Cochrane collaboration handbook. The databases PubMed, Cochrane Library, Web of Science, Scopus, CINAHL and Science Direct were searched until the end of January 2022. The DerSimonian and Laird methods were used to estimate the effect size with a 95% confidence interval (CI95%). Effect size estimates were 0.05 (95% CI: -0.19, 0.29) for HR, -0.02 (95% CI: -0.24, 0.21) for PIPP scale, and -0.12 (95% CI: -0.29, 0.05) for O2 saturation. The non-pharmacological interventions analysed (breastfeeding, kangaroo-mother care method, oral sucrose and non-nutritive sucking) were not statistically significant in reducing neonatal pain, but did influence the decrease in pain score and a faster stabilisation of vital signs.

Use of glucose for pain management in premature neonates: a systematic review and meta-analysis protocol

INTRODUCTION

Therapeutic management of neonatal pain is essential to reduce changes in initial and subsequent development. Although glucose has been shown to be effective in relieving pain, concentrations and dosages remain to be standardised. The objective of this systematic review and meta-analysis is to identify the efficacy of glucose as an analgesic in preterm infants.

METHODS AND ANALYSIS

The Web of Science, Science Direct, Scopus, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, PubMed, Medline, Latin American and Caribbean Health Sciences Literature and Embase databases will be researched for randomised studies published until December 2021. This systematic review and meta-analysis will include studies investigating the use of glucose for pain control in premature neonates. The primary outcome will be pain relief. Three independent reviewers will select the studies and extract the data from original publications. The risk of bias was assessed using the Cochrane risk of bias tool. Data synthesis will be performed using the Review Manager software (RevMan V.5.2.3). We will evaluate heterogeneity based on I2 statistics. In addition, quantitative synthesis will be performed if the included studies are sufficiently homogeneous.

ETHICS AND DISSEMINATION

Ethical approval for the research will not be required for this systematic review. The results of this study will be published in an international journal.

TRIAL REGISTRATION NUMBER

This protocol was submitted to the International Prospective Register of Systematic Reviews (PROSPERO, number CRD42021236217).
