Effectiveness of therapeutic hypothermia for mild neonatal encephalopathy: A protocol for systematic review and...

Neonates with moderate to severe encephalopathy benefit significantly from therapeutic hypothermia, with reduced risk of death or disability. However, the need for therapeutic hypothermia for mild neonatal encephalopathy (NE) remains unclear. Therefore, we conducted a protocol for systematic review and meta-analysis to provide evidence supporting therapeutic hypothermia for term or near term neonates with mild NE, including findings of recent long-term outcome studies, as well as novel adjunctive therapies to augment neurodevelopmental outcomes for neonates with NE who receive therapeutic hypothermia.

Two independent researchers performed a systematic literature search in different electronic databases including PubMed, the Cochrane Center Controlled Trials Register, EMBASE, Medline, Ovid, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wanfang Database without any restrictions of languages and date. Two reviewers will screen the records and include quality studies according to inclusion criteria independently. Two reviewers will assess the risk of bias of the included studies by the "Risk of Bias Assessment Tool" of the Cochrane Handbook for randomized controlled trials. Statistical analysis will be performed with Review Manager software 5.3.

A synthesis of current evidence of therapeutic hypothermia for treating mild NE will be provided in this protocol.

The results of this study will provide a theoretical basis for the clinical use of therapeutic hypothermia in mild NE.
