Survival of Pregnant Coronavirus Patient on Extracorporeal Membrane Oxygenation

[Pregnant women with COVID-19 ARDS on the intensive care unit]

BACKGROUND

Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk of severe disease progression. Comorbidities, such as chronic arterial hypertension, diabetes mellitus, advanced maternal age and high body mass index, may predispose to severe disease. The management of pregnant COVID-19 patients on the intensive care unit (ICU) is challenging and requires careful consideration of maternal, fetal and ethical issues.

OBJECTIVE

Description and discussion of intensive care treatment strategies and perinatal anesthesiological management in patients with COVID-19 acute respiratory distress syndrome (CARDS).

MATERIAL AND METHODS

We analyzed the demographic data, maternal medical history, clinical intensive care management, complications, indications and management of extracorporeal membrane oxygenation (ECMO) and infant survival of all pregnant patients treated for severe CARDS in the anesthesiological ICU of a German university hospital between March and November 2021.

RESULTS

The cohort included 9 patients with a mean age of 30.3 years (range 26-40 years). The gestational age ranged from 21 + 3 weeks to 37 + 2 weeks. None of the patients had been vaccinated against SARS-CoV‑2. Of the nine patients seven were immigrants and communication was hampered by inadequate Central European language skills. Of the patients five had a PaO2/FiO2 index < 150 mm Hg despite escalated invasive ventilation (FiO2 > 0.9 and a positive end-expiratory pressure [PEEP] of 14 mbar) and were therefore treated with repeated prolonged prone positioning maneuvers (5-14 prone positions for 16 h each, a total of 47 prone positioning treatments) and 2 required treatment with inhaled nitric oxide and venovenous ECMO. The most common complications were bacterial superinfection of the lungs, urinary tract infection and delirium. All the women and five neonates survived. All newborns were delivered by cesarean section, two patients were discharged home with an intact pregnancy and two intrauterine fetal deaths were observed. None of the newborns tested positive for SARS-CoV‑2 at birth.

CONCLUSION

High survival rates are possible in pregnant patients with CARDS. The peripartum management of pregnant women with CARDS requires close interdisciplinary collaboration and should prioritize maternal survival in early pregnancy. In our experience, prolonged prone positioning, an essential evidence-based cornerstone in the treatment of ARDS, can also be safely used in advanced stages of pregnancy. Inhaled nitric oxide (iNO) and ECMO should be considered as life-saving treatment options for carefully selected patients. For cesarean section, neuraxial anesthesia can be safely performed in patients with mild CARDS if well planned but the therapeutic anticoagulation recommended for COVID-19 may increase the risk of bleeding complications, making general anesthesia a more viable alternative, especially in severe disease.

Maternal-Fetal Results of COVID-19-Infected Pregnant Women Treated with Extracorporeal Membrane Oxygenation: A Descriptive Report

OBJECTIVE

COVID-19 infection may produce severe pneumonia, mainly in the adult population. Pregnant women with severe pneumonia are at high risk of developing complications, and conventional therapy sometimes fails to reverse hypoxemia. Therefore, extracorporeal membrane oxygenation (ECMO) is an option in cases with refractory hypoxemic respiratory failure. This study aims to evaluate the maternal-fetal risk factors, clinical characteristics, complications, and outcomes of 11 pregnant or peripartum patients with COVID-19 treated with ECMO.

STUDY DESIGN

This is a retrospective descriptive study of 11 pregnant women undergoing ECMO therapy during the COVID-19 pandemic.

RESULTS

In our cohort, four patients underwent ECMO during pregnancy (36.3%) and 7 during the postpartum period. Initially, they started on venovenous ECMO, and three patients were required to change modality due to clinical conditions. In total, 4/11 pregnant women (36.3%) died. We established two periods that differed in the implementation of a standardized care model for reducing associated morbidities and mortality. Neurological complications were responsible for most deaths. Regarding fetal outcomes at early-stage pregnancies on ECMO (4), we report three stillbirths (75%), and one newborn (twin pregnancy) survived and had a favorable evolution.

CONCLUSION

At later-stage pregnancies, all newborns survived, and we did not identify any vertical infection. ECMO therapy is an alternative for pregnant women with severe hypoxemic respiratory failure due to COVID-19, and may improve maternal and neonatal results. Regarding fetal outcomes, the gestational age played a definitive role. However, the main complications reported in our series and others are neurological. It is essential to develop novel, future interventions to prevent these complications.

Extra-corporeal membrane oxygenation and emergency C-section for a pregnant COVID-19 positive patient

INTRODUCTION

Data on extra-corporeal membrane oxygenation (ECMO) therapy for pregnant patients with Coronavirus 2019 (COVID-19) infection are limited. Here we report a case of an emergency cesarean section performed while the COVID-19 positive mother was on ECMO support.

CASE REPORT

A 36-year-old COVID-19 positive patient at 26 weeks gestational age presented with respiratory failure requiring extra-corporeal membrane oxygenation therapy. Nine days later fetal distress demanded an emergency C-section. After 5 weeks on ECMO, the patient was weaned off. Both mother and child were discharged.

DISCUSSION

The decision to perform an urgent C-section is one that requires meticulous thought from the attending team. Pulmonary maturation is key as pregnancy may need to be terminated at any time during ECMO.

CONCLUSION

Data on ECMO support for pregnant patients with COVID-19 infection are scarce. Best results can be achieved ensuring adequate anticoagulation, meticulous choice of cannulas, continued fetal monitoring, early lung maturation, and precision timing of delivery.

Full-Term Delivery and Complete Lung Recovery following VV ECMO Support Midpregnancy in a Patient with COVID-19 ARDS

Pregnant women are especially vulnerable to coronavirus disease 2019 (COVID-19). We present a twin pregnancy case with acute respiratory distress syndrome following COVID-19 infection at 19 weeks. The patient's ARDS was successfully managed with veno-venous extracorporeal membrane oxygenation (VV ECMO). She recovered completely and delivered healthy twins.

Use of Extracorporeal Membrane Oxygenation Therapy During Pregnancy and COVID-19: A Case Study

Extracorporeal membrane oxygenation is emerging as a vital resource for survival of patients with acute respiratory distress syndrome related to COVID-19. Although recent research provides much insight into the advantages of extracorporeal membrane oxygenation in this patient population, little has been published on its use in pregnancy. This case study describes the use of venovenous extracorporeal membrane oxygenation in a young pregnant woman with acute respiratory distress syndrome due to COVID-19. It illustrates the benefits of a multidisciplinary approach to this treatment modality, allowing time for a fetus to become viable while preserving the life of the mother. In this case, the mother was able to return home after receiving this therapy and resume normal activities of daily living independently.

COVID-19 in the Critically Ill Pregnant Patient

Pregnant women are at increased risk for severe coronavirus disease 2019 (COVID-19) and COVID-19-related complications. Their increased risk in conjuncture with the normal physiologic changes in pregnancy poses unique challenges for the management of the critically ill pregnant patient. This article will review the initial management of pregnant patients who develop acute hypoxic respiratory failure and subsequent treatment of those that deteriorate to acute respiratory distress syndrome and require advanced therapies. Moreover, fetal monitoring and timing of delivery will be reviewed.

Anesthesia Considerations for Pregnant People With COVID-19 Infection

The purpose of this review is to describe updates following initial recommendations on best anesthesia practices for obstetric patients with coronavirus disease 2019. The first surge in the United States prompted anesthesiologists to adapt workflows and reconsider obstetric anesthesia care, with emphasis on avoidance of general anesthesia, the benefit of early neuraxial labor analgesia, and prevention of emergent cesarean delivery whenever possible. While workflows have changed to allow sustained safety for obstetric patients and health care workers, it is notable that obstetric anesthesia protocols for labor and delivery have not significantly evolved since the first coronavirus disease 2019 wave.

Critical Care Management of a Severe Acute Respiratory Distress Syndrome COVID-19 Patient With Control Cesarean Section

We share our experience of one 29-year-old female, G2 P1, with acute respiratory distress syndrome (ARDS) and at 30 weeks of pregnancy. The 30-week gravid uterus in combination with a poor ventilation-perfusion ratio creates a restrictive lung pattern that may prove to be lethal for both the mother and baby. Due to her rapid deterioration and increased hemodynamic instability we opted for controlled delivery in the operating room with an ICU physician, a Neonatologist, and an Obstetric team. At 3.27 minutes from induction, the baby was born with Apgar scores of 7 and 8. The mother was placed on a RotoProne® bed, treated with remdesivir, steroids, and was subsequently extubated seven days later. The newborn was admitted to the Neonatal Intensive Care Unit (NICU) after delivery. We have reviewed the literature and provided a concise set of recommendations based on our field experience and current world literature review. Prompt delivery in a controlled environment with multiple resuscitating teams provided expeditious treatment of both patients, maintaining oxygenation and perfusion while keeping hemodynamic stability. The controlled environment and the proximity of all teams avoided deleterious consequences to the unborn baby. This is an example where the risk of keeping the baby in the womb outweighs the premature delivery into a NICU. Both mother and baby were downgraded from their respective Intensive Care Units (ICUs) and discharged home in one month. 

COVID-19-Related Acute Respiratory Distress Syndrome in a Pregnant Woman Supported on ECMO: The Juxtaposition of Bleeding in a Hypercoagulable State

A 40-year-old pregnant woman at 28 weeks of gestation was diagnosed with severe acute respiratory failure syndrome (ARDS) due to coronavirus disease 2019 (COVID-19). She had severe hypoxemia despite the use of mechanical ventilation and muscle relaxant infusion. Veno-venous extracorporeal membrane oxygenation (VV-ECMO) was used, and she had a cesarian section while on ECMO support. She developed disseminated intravascular coagulation (DIC) with overt bleeding. This was managed by a multidisciplinary team (MDT) and a change of the ECMO circuit resulted in a dramatic improvement of her coagulation profile. Both the mother and the baby were discharged and went home in good condition.

A successful case of extracorporeal membrane oxygenation for COVID-19: walking home without oxygen supplementation

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged from Wuhan, China in December 2019 and is the strain of coronavirus that causes coronavirus disease 2019 (COVID-19). Approximately one-third of the patients with COVID-19 require intensive care unit (ICU) admission, and almost 30% of the patients develop acute respiratory distress syndrome (ARDS). Extracorporeal membrane oxygenation (ECMO) is used as salvage therapy for severe ARDS. The role of ECMO in the treatment of COVID-19 remains unclear, although there is emerging evidence that this approach may be an effective salvage therapy for severe ARDS. Case Presentation: We present a case of a previously healthy 39-year-old Hispanic male who presented to the hospital with flu-like symptoms, including headache, fatigue, and myalgia for 8 days in late April 2020. He denied dyspnea on exertion. The patient's symptoms progressed, resulting in pneumonia and acute respiratory distress syndrome (ARDS). The patient was managed with prone positioning, convalescent plasma and veno-venous extracorporeal membrane oxygenation (VV-ECMO) for 35 days. The patient successfully recovered and was able to ambulate independently and was discharged home from an acute care hospital without oxygen supplementation on hospital day 63. Conclusion: We present one of the first few documented cases of ECMO for severe ARDS due to COVID-19. After a prolonged hospital course requiring VV-ECMO, the patient was discharged home from an acute care hospital without oxygen requirement and ambulated independently, likely as a result of daily aggressive mobility-focused rehabilitation.

A case of a pregnant patient with COVID-19 infection treated with emergency c-section and extracorporeal membrane oxygenation

Coronavirus disease 2019 (COVID‐19) causes the development of severe acute respiratory distress syndrome. Pregnant women may be at increased risk for the development of severe disease. We present the case of a pregnant patient who developed respiratory failure due to COVID‐19 and rapidly decompensated requiring intubation. Despite mechanical ventilation, the patient's respiratory status continued to worsen. At bedside, cardiothoracic surgeons, obstetricians, intensivists, and neonatologists discussed balancing the risk of COVID‐19 and respiratory failure to the patient, premature delivery to the neonate, potential coagulopathy associated with COVID‐19, and the need for anticoagulation with mechanical circulatory support. Ultimately, the decision was to proceed with emergency cesarean section delivery in the intensive care unit followed by peri‐partum veno‐venous extracorporeal membrane oxygenation initiation. The patient and neonate were both discharged home in stable condition.
