Obstetric Disorders and Critical Illness.

In this article, we discuss some of the more common obstetric-related conditions that can lead to critical illness and require management in an ICU. These include the hypertensive disorders of pregnancy, postpartum hemorrhage, hemolysis, elevated liver enzymes, and low platelet syndrome, acute fatty liver of pregnancy, amniotic fluid embolism, and peripartum cardiomyopathy. We also discuss pulmonary embolism and Covid-19. Despite not being specific to obstetric patients, pulmonary embolism is a common, life-threatening diagnosis in pregnancy with particular risks and management aspects. Covid-19 does not seem to occur with higher frequency in pregnant women, but it leads to higher rates of ICU admissions and mechanical ventilation in pregnant women than in their nonpregnant peers. Its prevalence during our current global pandemic makes it important to discuss in this article. We provide a basis for critical care physicians to be engaged in informed conversations and management in a multidisciplinary manner with other relevant providers in the care of critically ill pregnant and postpartum women.

Changing Trends of Pregnancy Related Acute Kidney Injury - a Single Centre Prospective Observational Study from Southern India

Introduction: Pregnancy-related acute kidney injury (PR-AKI) in India is largely showing a declining trend due to improved and accessible obstetric care. Nevertheless, PR-AKI continues to cause significant maternal and fetal morbidity and mortality. This study was taken up with the intention to study the incidence and clinical spectrum of AKI in pregnancy in recent times and assess maternal and neonatal outcomes Methods: All pregnant women admitted in the Department of Obstetrics and Gynecology at St John's Medical College Hospital, Bengaluru between January 2018 to June 2020 were screened for AKI with the following criteria 1. Increase in serum creatinine to >0.8mg/dL and/or a sudden increase in serum creatinine by more than 50% when prior renal function was normal. 2. Oligo-anuria 3. Need for renal replacement therapy Women with preexisting CKD were excluded. Patient's clinical and laboratory details recorded. Dialysis support was provided if indicated. The clinical profile and renal outcome of the mother and fetal outcome was assessed at the time of discharge. Mothers' were also followed up at the end of 3 months of postpartum period. Recovery was categorized as Complete recovery- normal serum creatinine (<0.8 mg/dL) or a previously known baseline and no proteinuria /hypertension at the end of 3 months Partial recovery- renal function improved but serum creatinine did not return to normal range and patient was dialysis independent. No recovery- patient continued to require dialysis at the end of 3months. Result(s): Of the 2650 deliveries in the study period 42 women (Mean age 26.9 +/-3.6 years) were diagnosed AKI during pregnancy (1.58%). Baseline characteristics and outcomes are depicted in table 1. Majority of women (n=37) were referred from peripheral hospitals. Hypertension and decreased fetal movements were the common reasons for referral. Third trimester was the most common time of presentation (76.1%). Severe Preeclampsia and HELLP syndrome was the leading cause of AKI (59.5%).ATN secondary to obstetric complications, sepsis and hemolytic uremic syndrome were the other causes. One case each of cortical necrosis, acute fatty liver of pregnancy and COVID 19 associated AKI was seen. Mean duration of hospital stay was 12.1+/-6.9 days. More than one third patients' required ICU stay (35.7%).12 patients (28.5%) required renal replacement therapy. Of them, 3 were dialysis dependent at the end of 3 months and 4 had partial renal recovery. 3 patients expired during hospital stay. Fetal survival was 69.04%.13 babies' required NICU care (44.8%). Neonatal outcomes are summarized in table 2. Close to one third of the pregnancies with AKI were associated with intrauterine fetal demise (28.5%). Low birth weight and prematurity were the common reasons for NICU admission with mean NICU stay of 8.2 +/-2.3 days [Formula presented] [Formula presented] Conclusion(s): Severe preeclampsia was the most common cause of AKI in our study. PR-AKI continues to be a significant problem in the peripheries of developing countries where availability of health care facilities is meager, with late referral to tertiary care centers. One third of the patients required ICU stay & dialytic support. Women who required dialysis had poorer renal prognosis. There was 30% fetal loss seen in PR-AKI and also a higher incidence of low birth weight and prematurity. No conflict of interestCopyright © 2023

Hepatic manifestations of COVID-19 in the obstetric population

COVID-19 has and continues to affect healthcare across the world. Pregnant women have been identified as a moderate-risk group with regards to clinical susceptibility to COVID-19. Acute liver injury in pregnancy secondary to COVID-19 has been documented sparsely across the world. In this report, we describe the case of a pregnant women who presented with COVID-19 liver injury. A second women with a similar presentation and outcome also presented during the same COVID-19 wave but contact details were lost and consent not gained. Description The cases occurred in December 2020 during which time the predominant reported variant was the alpha strain of COVID-19. Patient A was a multiparous woman, who presented to the labour ward at 37 weeks, a few days after a positive COVID-19 test with vomiting. Investigations revealed significant derangement of liver function tests (LFTs) but with normal bilirubin and clotting. On a working diagnosis of acute fatty liver of pregnancy and with breech presentation, she underwent a caesarean section. Liver enzymes continued to deteriorate with a mild coagulopathy. A non-invasive liver screen and ultrasound did not reveal any significant abnormalities. She was discussed with the tertiary liver centre and started on a Nacetylcysteine infusion with some additional vitamin K. A few days later LFTs began to improve and she was discharged home with follow-up in the community. Her baby was treated with antibiotics for 5 days empirically due to the unknown nature of the transaminitis but remained well. Following further discussion with the tertiary centre, a diagnosis of acute liver injury secondary to COVID-19 was made. Discussion Extra-pulmonary features of COVID-19 have been reported in the literature. A number of theories have been postulated to describe the hepatic effects. This has mainly manifested itself as a transaminitis with varying outcomes. The prevalence in the obstetric population has been more sparsely reported but most isolated cases have been relatively self-limiting with positive outcomes [1]. This case also highlighted the diagnostic difficulties with other severe hepatic diseases of pregnancy. A handful of case reports have already described some of the crossover and difficulty in decisionmaking when these patients present acutely unwell to hospital [2]. The severity and rapid progression of some hepatic disorders in pregnancy not only warrants decisive decision-making but also involvement of the multidisciplinary team.

Pregnancy With SARS-CoV-2 Infection Complicated by Preeclampsia and Acute Fatty Liver of Pregnancy.

The coronavirus disease 2019 (COVID-19) pandemic has spread across the world in a relentless and merciless way. As the pandemic escalates, varied presentations and complications of the disease have been reported from all over the world. Pregnant women fall into a vulnerable group who have been reported to have more severe disease and need of intensive care when compared to non-pregnant women of the same age group. Preeclampsia is one of the most common co-morbidity seen in pregnant women with COVID-19 infection. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can lead to worsening of pre-existing co-morbidities and extra vigilance is required in such cases. Here we present a case of a pregnant woman with COVID-19 infection with preeclampsia complicated by acute fatty liver of pregnancy and acute kidney injury. Although a rare diagnosis, a prompt multidisciplinary approach helped in achieving a favorable maternal and neonatal outcome.
