RESUMO
We report a rare case of in vitro fertilisation (IVF) with egg donation complicated by a subarachnoid haemorrhage (SAH). Haemostatic changes related to IVF are known to increase risk of venous thrombosis; however, less is known regarding the risk of arterial events such as cerebrovascular accidents (CVA). Matrix metalloprotease-9 (MMP-9) upregulated in IVF patients may have a role in arterial aneurysm formation, which is the most common cause of SAH. Further research is required to assess the benefit of screening for risk of CVA and the best way to manage this in the IVF population. This may have implications for the ethics of offering certain procedures such as egg donation to women with pre-existing risk factors.
RESUMO
BACKGROUND: In many low and medium human development index countries, the rate of maternal and neonatal morbidity and mortality is high. One factor which may influence this is the decision-to-delivery interval of emergency cesarean section. We aimed to investigate the maternal risk factors, indications and decision-to-delivery interval of emergency cesarean section in a large, under-resourced obstetric setting in Uganda. METHODS: Records of 344 singleton pregnancies delivered at ≥24 weeks throughout June 2017 at Mulago National Referral Hospital were analysed using Cox proportional hazards models and multivariate logistic regression models. RESULTS: An emergency cesarean section was performed every 104 min and the median decision-to-delivery interval was 5.5 h. Longer interval was associated with preeclampsia and premature rupture of membranes/oligohydramnios. Fetal distress was associated with a shorter interval (p < 0.001). There was no association between decision-to-delivery interval and adverse perinatal outcomes (p > 0.05). Mothers waited on average 6 h longer for deliveries between 00:00-08:00 compared to those between 12:00-20:00 (p < 0.01). The risk of perinatal death was higher in neonates where the decision to deliver was made between 20:00-02:00 compared to 08:00-12:00 (p < 0.01). CONCLUSION: In this setting, the average decision-to-delivery interval is longer than targets adopted in high development index countries. Decision-to-delivery interval varies diurnally, with decisions and deliveries made at night carrying a higher risk of adverse perinatal outcomes. This suggests a need for targeting the improvement of service provision overnight.
