Neurocritical Care of the Pregnant Patient

Neurologic Emergencies in Pregnancy

Neurologic emergencies in pregnancy require prompt evaluation and early, focused intervention to improve neurologic outcomes for the affected person and to avoid further injury. Neurologic events in pregnancy, although rare, present a time of extreme risk of permanent injury for the person who is pregnant. Therefore, obstetric clinicians should be well versed in the risk factors for potential neurologic events and understand the symptoms and events that should prompt evaluation for a neurologic event. In addition, they should support other specialties in aggressive and early neurologic care for the patient to improve outcomes while assessing fetal well-being and care optimization for the dyad. Obstetric clinicians can uniquely provide knowledge of changes in pregnancy physiology that can increase the risk of neurologic events, as well as change the treatment of these events. For all patients with neurologic events, "time is brain." Therefore, it is important to be aware of changes in common presenting pregnancy concerns that should prompt evaluation for other pathogeneses. Finally, pregnancy care teams should be prepared to begin the initial stabilization and management of acute neurologic emergencies, including seizure, stroke, and meningitis, while seeking aid from other medical and neurologic specialists who can support their care and interventions. Early and aggressive interventions for individuals with neurologic events during pregnancy and postpartum are critical to the overall well-being of the dyad.

Cardiopulmonary Arrest During Pregnancy: A Review Article

Massive pulmonary embolism (PE) is an uncommon but severe complication of pregnancy or during the first few weeks after giving birth. Our intention was to thoroughly analyze the information available to its management methods. Significant bleeding of mother survival and early deliveries in fetal survivals were having hemorrhage and were having key outcomes. We found 127 severe PE cases that have had at least one form of treatment (at least 83% big; 23% with cardiac arrest). The 83 women who received thrombolysis had a 94% (95%) survival rate. Cardiac arrest in pregnancy is uncommon, although maintaining current competency can be challenging. While maternal mortality rates have decreased globally over the past 25 years, they have increased in the United States. The intricacy of the maternal mortality issue is a result of a number of clinical and socioeconomic problems such as unequal healthcare access, racial and ethnic disparities, maternal comorbidities, and bias in epidemiologic ascertainment. The importance of doctors being prepared to react to a potential maternal cardiac arrest in any situation where they are providing treatment for pregnant women is highlighted by the rise in maternal mortality. For the treatment of maternal cardiac arrest, an interdisciplinary team with expertise in both the maternal resuscitation procedure and the physiological changes that take place during pregnancy is necessary. Additionally offered are basic and advanced cardiac life support protocols. Techniques to remove obstacles like aortocaval compression that could impair the effectiveness of resuscitation should be used.

Ten Rules for the Management of Moderate and Severe Traumatic Brain Injury During Pregnancy: An Expert Viewpoint

Moderate and severe traumatic brain injury (TBI) are major causes of disability and death. In addition, when TBI occurs during pregnancy, it can lead to miscarriage, premature birth, and maternal/fetal death, engendering clinical and ethical issues. Several recommendations have been proposed for the management of TBI patients; however, none of these have been specifically applied to pregnant women, which often have been excluded from major trials. Therefore, at present, evidence on TBI management in pregnant women is limited and mostly based on clinical experience. The aim of this manuscript is to provide the clinicians with practical suggestions, based on 10 rules, for the management of moderate to severe TBI during pregnancy. In particular, we firstly describe the pathophysiological changes occurring during pregnancy; then we explore the main strategies for the diagnosis of TBI taking in consideration the risks related to mother and fetus, and finally we discuss the most appropriate approaches for the management in this particular condition. Based on the available evidence, we suggest a stepwise approach consisting of different tiers of treatment and we describe the specific risks according to the severity of the neurological and systemic conditions of both fetus and mother in relation to each trimester of pregnancy. The innovative feature of this approach is the fact that it focuses on the vulnerability and specificity of this population, without forgetting the current knowledge on adult non-pregnant patients, which has to be applied to improve the quality of the care process.

Status epilepticus in pregnancy: a literature review and a protocol proposal

INTRODUCTION

Status epilepticus (SE) in pregnancy represents a life-threatening medical emergency for both mother and fetus. Pregnancy-related pharmacokinetic modifications and the risks for fetus associated with the use of antiseizure medications (ASMs) and anesthetic drugs complicate SE management. No standardized treatment protocol for SE in pregnancy is available to date.

AREAS COVERED

In this review, we provide an overview of the current literature on the management of SE in pregnancy and we propose a multidisciplinary-based protocol approach.

EXPERT OPINION

Literature data are scarce (mainly anecdotal case reports or small case series). Prompt treatment of SE during pregnancy is paramount and a multidisciplinary team is needed. Benzodiazepines are the drugs of choice for SE in pregnancy. Levetiracetam and phenytoin represent the most suitable second-line agents. Valproic acid should be administered only if other ASMs failed and preferably avoided in the first trimester of pregnancy. For refractory SE, anesthetic drugs are needed, with propofol and midazolam as preferred drugs. Magnesium sulfate is the first-line treatment for SE in eclampsia. Termination of pregnancy, via delivery or abortion, is recommended in case of failure of general anesthetics. Further studies are needed to identify the safest and most effective treatment protocol.

Risk factors for pregnancy-related clinical outcome in myasthenia gravis: a systemic review and meta-analysis

OBJECTIVE

Myasthenia gravis (MG) is an autoimmune disorder that frequently affects females at reproductive age. Herein, we aimed to assess the associations of clinical factors with pregnancy-related outcome in MG.

METHODS

We searched PubMed and EMBASE for case-control and cohort studies that reported the MG status during or after pregnancy and relevant clinical variables. The data was extracted in proportions and odds ratios (ORs) with 95% confidence intervals (CIs) in subsequent meta-analysis.

RESULTS

Fifteen eligible articles reporting on 734 pregnancies with 193 worsening and 51 improved episodes were included out of 1765 records. The estimated worsening proportions in total, antepartum and postpartum periods were 0.36 (95% CI 0.25-0.40), 0.23 (95% CI 0.14-0.34) and 0.11 (95% CI 0.04-0.22) respectively. The proportion of pregnancy-related improvement in enrolled patients was 0.28 (95% CI 0.17-0.40), with 0.07 (95% CI 0.00-0.28) during pregnancy and 0.14 (95% CI 0.02-0.34) after pregnancy. No significant associations were disclosed between the clinical factors and MG worsening. Thymectomy before delivery is a strong predictor for MG improvement in postpartum period (OR 4.85, 95% CI 1.88-12.50, p = 0.001).

CONCLUSION

The total proportion of pregnancy-related MG worsening and improvement in MG was 0.36 (95% CI 0.25-0.40) and 0.28 (95% CI 0.17-0.40), respectively. Thymectomy before the delivery may aid in clinical improvements associated with pregnancy. Future prospective cohort studies are required to determine more relevant factors.
