Data from meta-analyses finds that epidural compared with systemic opioids in labour is associated with reduced neonatal respiratory depression. Clinically relevant neonatal outcomes such as Apgar score <7 at 5 min, neonatal resuscitation and need for admission to a neonatal unit are reassuring, with the benefits of epidural analgesia for both mother and neonate outweighing any potential risks. Recent concerns regarding an association of epidural with the development of autism spectrum disorder in childhood appear to be unfounded, with several large observational studies refuting this association.

This review summarises current preclinical evidence. Most studies used rodent models, although non-human primates have also been employed. Across all gestational and postnatal ages, there is evidence that all commonly used general anaesthetics induce neuronal injury (e.g. apoptosis) and cause neurobehavioural impairment (e.g. learning and memory deficits). These deficits were more pronounced when animals were subjected to either repeated exposure, prolonged durations of exposure or higher doses of anaesthesia. To interpret these results in the clinical context, the strengths and limitations of each model and experiment should be carefully considered, as these preclinical studies were often biased by supraclinical durations and a lack of control with regard to physiological homeostasis.</span></p></div>","PeriodicalId":48541,"journal":{"name":"Best Practice & Research-Clinical Anaesthesiology","volume":"37 1","pages":"Pages 16-27"},"PeriodicalIF":4.8,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9629296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
