Abstract
Background
Neonatal hypernatremic dehydration (NHD) is a severe condition associated with neonatal morbidity and mortality.
Purpose
The present study evaluated maternal risk factors, including duration of maternal hospitalisation, primiparity, caesarean section, and pregnancy complications, as well as social factors, such as depression, fatigue, and inadequate support for NHD.
Data Sources
PubMed, Cochrane Library, International Scientific Indexing, Scopus, and Google Scholar were the databases searched until 2023.
Study Selection
Articles written in English or Persian focusing on the relationship between maternal risk factors and NHD among neonates and providing sufficient information on NHD were included in this study. On the other hand, articles whose abstracts were only available were excluded.
Data Extraction
The extracted data were presented in Excel software with the following titles: authors' names, year, type of study, study location, and maternal risk factors. The methodological quality of the articles was determined using the quality assurance tool for the diagnostic accuracy score (QUADAS).
Results
Of the 58 searched articles, 16 were investigated, which included five prospective, seven cross-sectional, and four retrospective articles. Maternal risk factors for NHD included labour and delivery complications, childbirth complications, factors causing insufficient breast milk intake (including breast milk insufficiency, nipple problems, wrong breastfeeding techniques, breast disorders, types of feeding, and breastfeeding training/counselling in pregnancy), as well as delivery and the postpartum period.
Implications for Practice and Research
Maternal problems in pregnancy and delivery, breast disorders, breastfeeding status, maternal knowledge, and lactation skills are the most common maternal risk factors for NHD. Timely (antenatal) identification and proper management of maternal risk factors help reduce the incidence and severity of NHD complications.
