Low A pgar score, neonatal encephalopathy and epidural analgesia during labour: a S wedish registry‐based study
Abstract
Background: Maternal intrapartum fever (MF) is associated with neonatal sequelae, and women in labour who receive epidural analgesia (EA) are more likely to develop hyperthermia. The aims of this study were to investigate if EA and/or a diagnosis of MF were associated to adverse neonatal outcomes at a population level. Methods: Population‐based register study with data from the S wedish B irth R egister and the S wedish N ational P atient R egister, including all nulliparae (n = 294,329) with singleton pregnancies who gave birth at term in S weden 1999–2008. Neonatal outcomes analysed were A pgar score (AS) < 7 at 5 min and ICD‐10 diagnosis of neonatal encephalopathy (e.g. convulsions or neonatal cerebral ischaemia). Multivariate logistic regression was used to calculate adjusted odds ratios (AOR) with 95% confidence intervals (CI). Results: EA was used in 44% of the deliveries. Low AS or encephalopathy was found in 1.26% and 0.39% of the children in the EA group compared with 0.80% and 0.29% in the control group. In multivariate analysis, EA was associated with increased risk with low AS, AOR 1.27 (95% CI 1.16–1.39), but not with diagnosis of encephalopathy, 1.11 (0.96–1.29). A diagnosis of MF was associated with increased risk for both low AS, 2.27 (1.71–3.02), and of neonatal encephalopathy, 1.97 (1.19–3.26). Conclusion: Diagnosis of MF was associated with low AS and neonatal encephalopathy, whereas EA was only associated with low AS and not with neonatal encephalopathy. The found associations might be a result of confounding by indication, which is difficult to assess in a registry‐based population study.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
