Interventions for treating umbilical granuloma: a protocol for a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION

The most frequent umbilical abnormality in infancy period is umbilical granuloma. Although umbilical granuloma treatment with silver nitrate is practised worldwide, silver nitrate cauterisation is high in cost and if silver nitrate comes into contact with healthy tissues, it might cause injury. This systematic review aims to look for evidence concerning the safety and efficacy of all interventions for treating umbilical granuloma in neonates.

METHODS AND ANALYSIS

Individual and cluster randomised controlled trials will be included in our study. The direct comparisons between two of any interventions for treating umbilical granuloma, including silver nitrate cauterisation, dry care, common salt, alcoholic wipes, topical doxycycline, topical steroid ointment, ligatures, cryosurgery, electrocautery, surgical excision and no intervention will be investigated. Primary outcomes will be the healing rate after 2 weeks of treatment and the incidence of cord-related adverse events. We will search CENTRAL, Embase and MEDLINE.

ETHICS AND DISSEMINATION

Ethical approval is not applicable in this study since we will retrieve and analyse data from previous published studies. The results of this systematic review are expected to be published in a scientific journal and presented at medical conferences.
