Description
Summary:Background Status epilepticus (SE) is defined as 5 min or more of seizure activity or two recurrent seizures without a return to baseline. Healthcare providers encounter a challenge when a patient with SE is pregnant. SE is not only detrimental to the mother but can also put the baby at risk of severe harm. SE must be treated rapidly and therefore healthcare providers have very little time to thoroughly review the risk and benefits of available antiseizure medication in this population. Aim To evaluate the current available evidence related to the management of SE in pregnancy. Design A literature search of PubMed, CINAHL, ProQuest Nursing & Allied Health Source, and Web of Science databases was conducted (2012–2022) using the following search terms: ‘pregnancy’, ‘pregnant women’ OR ‘gestation’ AND ‘status epilepticus’, ‘generalized status epilepticus’, ‘generalized convulsive status epilepticus’, ‘non convulsive status epilepticus’ OR ‘non‐convulsive status epilepticus’. Full‐text randomised controlled trials, clinical trials, observational studies, and case reports published in English were included. Data were extracted and the quality of the studies was evaluated using the Mixed Methods Appraisal Tool. Results The literature described 29 pregnancies and 30 total foetuses. Intravenous benzodiazepine use for emergent control was reported in 45% of patients. Phenytoin and levetiracetam were primarily utilised for urgent control, with a variety of agents used for refractory SE. Ninety‐seven percent of maternal outcomes were reported as positive. The most common outcome was the birth of a healthy term infant. There were seven cases of pregnancy loss. Conclusion Publications pertaining to the treatment of SE in pregnancy are limited to case reports and small observational studies. Use of a benzodiazepine followed by levetiracetam or phenytoin is appropriate, whereas valproic acid should be utilised only when necessary due to the risk of major congenital malformation.
