摘要
AimThe aetiology of perinatal stroke is poorly understood. This study aimed to prospectively confirm the risk factors and identify any previously unknown variables. MethodsA prospective case-control study was conducted in Australia. Univariate odds ratios (ORs), associated 95% confidence intervals (CIs) and multivariable logistic regression models fitted with backwards stepwise variable selection were used. ResultsSixty perinatal stroke cases reported between 2017 and 2019 included 95% (57/60) with multiple risk factors. Univariate analysis identified emergency caesarean section rather than NVD (P < 0.01), low Apgar score (<7) at 1, 5 and 10 min of age (P < 0.01), resuscitation at birth (P < 0.01), abnormal cord blood gas (P < 0.01), neonatal infection/sepsis (P < 0.01), congenital heart disease (P < 0.01) and hypoglycaemia (P < 0.01) as significant risk factors. Multivariate analysis found smoking during pregnancy (OR: 1.48; 95% CI: 1.09-1.99), 1-min Apgar score < 7 (OR: 1.54; 95% CI: 1.15-2.08), 10-min Apgar score < 7 (OR: 1.26; 95% CI: 1.02-1.54) and hypoglycaemia (OR: 1.49; 95% CI: 1.07-2.06). ConclusionsPerinatal stroke is associated with multiple risk factors. Exposure to smoking, 10-min Apgar score < 7, neonatal infection and hypoglycaemia were independent risk factors. Emergency caesarean section, resuscitation at birth and abnormal cord blood gas were additional risk factors.
