Review Meta Analysis
Intravenous Ringer's lactate versus usual care during labor in nulliparous women: a systematic review and meta-analysis of randomized controlled trials.
Due to limited research on the effectiveness and safety of intravenous (IV) fluids administered during labor, there are no guidelines available. Thus, this meta-analysis aims to evaluate efficacy of IV Ringer's lactate during labor as compared to usual care. ⋯ IV Ringer's lactate reduced the duration of active labor, the need for oxytocin augmentation and the prolonged labor incidence. However, it did not differ in effect on immediate neonatal health but was found to have more potential for reducing maternal vomiting as compared to usual care with unrestricted oral intake. Further research is needed to explore its effects in the larger and more diverse populations and with different IV fluids for evidence-based guidelines.
