Maternal death from stroke: a thirty year national retrospective review

Objective

In the United Kingdom (UK), the maternal mortality rate from stroke is reported at 0.3/100,000 deliveries, but only antenatal data have previously been reviewed. We hypothesise that the true rate is much higher due to a propensity for stroke occurring in the post-partum period, and that the rate will rise in parallel with trends of increasing maternal age and medical co-morbidities. Our objectives are to investigate the UK stroke mortality rate in pregnancy and the puerperium, and to examine temporal changes in fatal maternal strokes over a 30 year period.

Study design

Retrospective review of stroke-related maternal deaths reported to the UK confidential enquiries into maternal death between 1979 and 2008, encompassing 21,514,457 maternities. In accordance with the ICD.10 classification, cases were divided into direct or indirect deaths. Late and coincidental deaths were not included in analyses. Lessons from sub-standard care associated with maternal death from stroke were collated.

Results

In 1979–2008 there were 347 maternal deaths from stroke: 139 cases were direct deaths, i.e. the fatal stroke was a direct result of pregnancy. The incidence of fatal stroke is relatively constant at 1.61/100,000 maternities, with a 13.9% (95% CI 12.6–15.3) proportional mortality rate. Intracranial haemorrhage was the single greatest cause of maternal death from stroke.

Conclusion

This is the largest UK study examining the incidence of fatal maternal stroke in pregnancy and the puerperium. Our results highlight the high proportion of women who die from stroke in the puerperium. Sub-standard care featured especially in regard to management of dangerously high systolic blood pressure levels. These deaths highlight the importance of education in managing rapid-onset hypertension and superimposed coagulopathies.     

Maternal deaths: initial report of an on-going monitoring of maternal deaths at the Federal Medical Centre Katsina,Northwest Nigeria

Abstract

Objectives: To assess the maternal mortality ratio (MMR) from data collected as maternal deaths occurred over a 4-year period.

Methods: A Departmental database established in 2008 was used to keep data on deliveries and maternal deaths as they occurred. The causes of death were decided after a meeting reviewed the case. Analysis was done using Microsoft Excel software and results presented in means and frequencies.

Results: Eight thousand two hundred and twenty live deliveries that occurred were complicated by 68 maternal deaths. The MMR was 827/100?000 live births. The MMR for unbooked women was four times higher than for booked women. Obstetric haemorrhage was the main (21.6%) direct cause of death followed by preeclampsia/eclampsia (18.9%). While anaemia was the leading (8.1%) indirect cause of death, tetanus in the puerperium reared its head as an emerging (5.4%) indirect cause of maternal death. None of the women ever used contraceptives. Most deaths occurred in teenage mothers (23.5%), unbooked women (86%) and in the postpartum period (69%).

Conclusion: The MMR was high and tetanus in puerperium emerged as an indirect cause of maternal deaths. There is a need to curb the emergence of tetanus in the puerperium as a cause of maternal death.     

Maternal mortality among Palestinian women in the West Bank.

OBJECTIVE: To assess maternal mortality and determine the most common causes of maternal death among Palestinian women. METHODS: Available data on the 431 women who died between the ages of 15 and 49 years in the West Bank in 2000 and 2001 were reviewed. The data were collected from official agencies and, using the verbal autopsy approach, interviews of the deceased women's relatives. The interviews were conducted in all 10 districts of the West Bank over 30 months. RESULTS: Maternal mortality ratios for 2000 and 2001 were 29.2 and 36.5 per 100,000 live births, respectively. Cardiovascular diseases and hemorrhage were the most common causes of death. Misclassification was found in 38% of the deaths. A tentative analysis of avoidability indicated that 69% of maternal deaths could be classified as avoidable. CONCLUSION: A majority of the maternal deaths identified were avoidable. Substandard classification of maternal deaths is hampering efforts to reduce maternal mortality.     

Maternal mortality in health institutions with emergency obstetric care facilities in Enugu State, Nigeria.

In order to assess the current level of maternal mortality in health institutions with comprehensive emergency obstetric care in Enugu State, South Eastern Nigeria, a retrospective analysis of maternal deaths for the years 1999-2003 was carried out to establish the maternal mortality ratios in the eligible health institutions. Each maternal death was studied in detail to establish the socio-demographic characteristics of the women who died; their referral sources, type of delay (if any), medical causes of death and their preventability. In-depth interviews of the service providers were carried out to throw more light on the maternal mortality situation in the state. Five out of seven eligible health institutions were studied. Within the 5-year period (1999-2003), there were 141 maternal deaths and 18,257 live births giving a maternal mortality ratio of 772 maternal deaths per 100,000. The folders of 89 out of the 141 women who died were retrieved. Of these 89 maternal deaths, 51.7% of them were unemployed, 52.4% were referred from private hospitals; type 3 delay was the commonest type of delay encountered in the care of the women. Referral delay was the main cause of delay accounting for 46.4% of all cases of type 3 delay. The leading causes of maternal deaths among the women were obstetric haemorrhage (19.1%), sepsis (18.0%), prolonged obstructed labour/ruptured uterus (16.9%) and pre-eclampsia/eclampsia (16.9%). The in-depth interviews corroborated the high maternal mortality ratio recorded and the type 3 delays in tackling obstetric emergencies. It also showed some discrepancies between reality and the health providers' perception of the magnitude of maternal mortality situation in the state. It was concluded that in health institutions in Enugu State with comprehensive emergency obstetric care facilities, the maternal mortality ratio remains high due to type 3 delays. Most of the referrals come from private hospitals, hence the need to retrain the private practitioners in emergency obstetric care.     

Maternal mortality from cardiac disease in Turkey: a population-based study

Objective: Population-based studies on maternal deaths in Turkey are rare. The aim of the present study was to analyze the cardiac causes of all maternal deaths in Turkey between 2007 and 2009. Materials and methods: In this retrospective study, case files of all pregnancy-associated deaths recorded in Turkey between 2007 and 2009 were reviewed. Records for all pregnancy-associated deaths were reviewed by five authors to identify 129 cases in which a cardiac disease seemed to be the reason. For each of the 129 cases, maternal age, gravidity, parity, antenatal care attendance, district of residence, year of death, mode of delivery, perinatal outcome, and clinical history preceding death were recorded. Results: During the study period, 779 maternal deaths were identified. Our estimate of the maternal mortality ratio (MMR) in 3-year period was 19.7 per 100,000 live births. The report lists 779 deaths, 411 direct and 285 indirect. Indirect obstetric causes of maternal death were primarily cardiac disorders and cerebrovascular diseases. Maternal mortality due to cardiac disease was 15.5% in 2007 and 18.4% in 2008. Valvular heart disease was the leading cause of maternal death from cardiac reasons (25.6%). Maternal mortality due to cardiac disease increased with age. Conclusion: The main cause of indirect maternal death has been cardiac disease in 3-year period.     

Pregnancy-related mortality from preeclampsia and eclampsia

OBJECTIVE: To examine the role of preeclampsia and eclampsia in pregnancy-related mortality. METHODS: We used data from the Centers for Disease Control and Prevention's Pregnancy Mortality Surveillance System to examine pregnancy-related deaths from preeclampsia and eclampsia from 1979 to 1992. The pregnancy-related mortality ratio for preeclampsia-eclampsia was defined as the number of deaths from preeclampsia and eclampsia per 100,000 live births. Case-fatality rates for 1988-1992 were calculated for preeclampsia and eclampsia deaths per 10,000 cases during the delivery hospitalization, using the National Hospital Discharge Survey. RESULTS: Of 4024 pregnancy-related deaths at 20 weeks' or more gestation in 1979-1992, 790 were due to preeclampsia or eclampsia (1.5 deaths/100,000 live births). Mortality from preeclampsia and eclampsia increased with increasing maternal age. The highest risk of death was at gestational age 20-28 weeks and after the first live birth. Black women were 3.1 times more likely to die from preeclampsia or eclampsia as white women. Women who had received no prenatal care had a higher risk of death from preeclampsia or eclampsia than women who had received any level of prenatal care. The overall preeclampsia-eclampsia case-fatality rate was 6.4 per 10,000 cases at delivery, and was twice as high for black women as for white women. CONCLUSION: The continuing racial disparity in mortality from preeclampsia and eclampsia emphasizes the need to identify those differences that contribute to excess mortality among black women, and to develop specific interventions to reduce mortality from preeclampsia and eclampsia among all women.     

Obstetric deaths in Bangladesh, 1996-1997.

OBJECTIVES: The purpose of this study was to measure and to describe obstetric deaths in Bangladesh. METHODS: We reviewed hospital records and interviewed health workers in clinic sites and field workers who cared for pregnant women. RESULTS: We obtained case reports of 28998 deaths of women aged 10-50, of which 8562 (29.5%) were maternal deaths. Most (7086, 82.8%) of these deaths were due to obstetric causes. The most common causes of direct obstetric death were eclampsia (34.3%), hemorrhage (27.9%), and obstructed and/or prolonged labor (11.3%). National direct obstetric death rate was estimated to be 16.9 per 100,000 women. CONCLUSIONS: Efforts to reduce fertility in Bangladesh have led to an estimated 49% reduction in the maternal mortality rate per 1000 women during the past 18 years. Variations in maternal mortality suggest the need to develop local strategies to improve obstetric care.     

The demography of maternal mortality--seven Swedish parishes in the 19th century

Complications of childbirth is a leading death cause for women of reproductive ages in the developing countries today. The unique Swedish population statistics from the 19th century permit comparable historical studies. In seven Swedish parishes 170 maternal deaths were observed - 595 per 100,000 live births. Eclampsia, obstructed labor and hemorrhage were responsible for 92 deaths, and puerperal sepsis for only 15 deaths. Indirect obstetrical deaths, like pneumonia, tuberculosis, dysentery and heart diseases, accounted for 30.8% (41/133) of the specified death causes. With a time limit of 1 year instead of 42 days following delivery, maternal mortality was increased by 17%. Out of 14 married women 1 died from childbirth. Maternal deaths accounted for 40-50% of all deaths in the central ages of reproduction, leaving the motherless children with a highly increased death risk. Of the live born, 3% survived 5 years after the mothers' death. Of children aged 1-5 only 13% survived 5 years after the mothers death.     

National maternal mortality ratio for Jordan, 2007-2008

Objective

To estimate the number of maternal deaths per 100 000 live births during 2007-2008 among Jordanian women; to identify the causes of maternal mortality; and to compare the results with those of the last report for 1995-1996.

Methods

Reproductive-age mortality study of maternal deaths among women aged 15-49 years in Jordan in 2007-2008.

Results

Among 1406 identified deaths of reproductive-aged women, 76 maternal deaths were identified out of 397 588 live births, for a maternal mortality ratio of 19.1 deaths per 100 000 live births. Forty-three (56.6%) deaths were attributable to hemorrhage, thrombosis and thromboembolism, and sepsis. Avoidable factors were present in 53.9% of women, 52.6% had substandard care, and 31.5% had 3 or fewer antenatal visits. Of those with available information on family planning, only 29.4% had ever used any form of contraception.

Conclusions

Maternal deaths in Jordan are declining. The maternal mortality ratio of 19.1 deaths per 100 000 live births reported for 2007-2008 showed a remarkable reduction of 53.9% achieved in the 12 years since the 1995-1996 report (a 4.5% annual reduction), which is approaching the 75% reduction recommended by Millennium Development Goal 5.     

Insights into maternal mortality in Madang Province,Papua New Guinea

Objective

To assess the frequency, causes, and reporting of maternal deaths at a provincial referral hospital in coastal Papua New Guinea (PNG), and to describe delays in care.

Methods

In a structured retrospective review of maternal deaths at Modilon General Hospital, Madang, PNG, registers and case notes for the period January 2008 to July 2012 were analyzed to determine causes, characteristics, and management of maternal death cases. Public databases were assessed for underreporting.

Results

During the review period, there were 64 maternal deaths (institutional maternal mortality ratio, 588 deaths per 100 000 live births). Fifty-two cases were analyzed in detail: 71.2% (n = 37) were direct maternal deaths, and hemorrhage (n = 24, 46.2%) and infection (n = 16, 30.8%) were the leading causes of mortality overall. Women frequently did not attend prenatal clinics (n = 34, 65.4%), resided in rural areas (n = 45, 86.5%), and experienced delays in care (n = 45, 86.5%). Maternal deaths were underreported in public databases.

Conclusion

The burden of maternal mortality was found to be high at a provincial hospital in PNG. Most women died of direct causes and experienced delays in care. Strategies to complement current hospital and national policy to reduce maternal mortality and to improve reporting of deaths are needed.

Abstract：

Objectives To find problems in the systematic management of maternal health and to provide evidence for developing effective interventions to reduce maternal mortality in Shanghai. Methods Every maternal death from 2000 to 2009 was audited by experts and relevant informations were collected and analyzed retrospectively. Results ( 1 ) Number of live births. The number of live births in Shanghai rised from 84 898 in 2000 to 187 335 in 2009, which increased by 120. 7%. Notably, the number of live births of migrating people increased 4. 6 times. In 2000, it took up 25.5% and in 2009, it rose to 54. 8%. ( 2 )Maternal mortality ratio (MMR) and its composition. The total live births from 2000 to 2009 was 1 279 010,among which there were 262 maternal deaths, with average maternal mortality of 20. 48 per 100 000 live birth (262/1 279 010). For Shanghai residents, the MMR was 8.09 per 100 000 live births (55/680 005 ),while the MMR of migrating people was 34. 56 per 100 000 live births ( 207/599 005 ). ( 3 ) Trends of MMR. The MMR declined from 21.2 per 100 000 live births in 2000 to 9.61 per 100 000 live births in 2009. The MMR of Shanghai residents maintained below 10 per 100 000 live births with exception of year 2003 and 2004. The MMR of migrating people declined sharply. In 2002 it was 77.42 per 100 000 live births, and in 2009 it decreased to 11. 69 per 100 000 live births. (4)The composition of causes of maternal deaths and rank order. The top 5 causes of deaths were obstetric hemorrhage (69 cases, 26. 3% of the total deaths), pregnancy induced hypertension (27 cases, 10. 3% of the total deaths), heart diseases (24 cases,9. 2% of the total deaths), liver diseases ( 17 cases, 6. 5% of the total deaths), amniotic fluid embolism and ectopic pregnancy ( 15 cases respectively, 5.7% of the total deaths). ( 5 ) The changes of causes between the first 5 years and the latter 5 years. The MMR of ectopic pregnancy, heart diseases and pregnancy induced hypertension changed significantly in Shanghai residents. The MMR of ectopic pregnancy decreased from 1.36 per 100 000 live births in the first 5 years to 0. 26 per 100 000 live births in the latter 5 years. The MMR of heart diseases decreased from 1.36 per 100 000 live births to 0. 52 per 100 000 live births. While the MMR of pregnancy induced hypertension increased from 0 to 0. 78 per 100 000 live births. For migrating population, the MMR of obstetric hemorrhage, ectopic pregnancy and pregnancy induced pregnancy deceased significantly. As the primary cause, the MMR of obstetric hemorrhage deceased from 21.85 per 100 000 live births in the first 5 years to 5.47 per 100 000 live births in the second 5 years. The MMR of ectopic pregnancy decreased from 4. 37 per 100 000 live births to 0. 68 per 100 000 live births. And the MMR of pregnancy induced hypertension decreased from 6. 87 per 100 000 live births to 2. 96 per 100 000 live births.(6) Direct obstetric causes and indirect obstetric causes of maternal deaths. Among the 262 deaths,141 cases (53. 8% ) were due to Direct obstetric causes and 121 (46. 2% ) were due to indirect obstetric causes. (7)The trend of MMR of obstetric hemorrhage. The MMR of obstetric hemorrhage declined from 10. 6 per 100 000 live births in 2000 to 1.7 per 100 000 live births in 2009. ( 8 ) The results of maternal death audit. The results of maternal death audit were classified into 3 categories: 41 cases ( 15.6% )belonged to the first category, i. e, avoidable deaths; 66 cases (25.2%) belonged to the second category,i. e, avoidable when creating some conditions; and 155 cases (59. 2% ) belonged to the third category,which means not avoidable. Among 55 deaths of Shanghai residents, 17 cases (30. 9% ) belonged to the first category, 14 cases (25.5%) belonged to the second, and 24 cases (43.6%) belonged to the third category. Among 207 deaths of migrating population, 24 cases (11.6%) belonged to the first category,52 cases (25. 1% ) belonged to the second, and 131 cases (63.3%) belonged to the third category. (9)WHO twelve-grid classification of maternal deaths. The factors, including attitude, knowledge and skills, resources and management of the dead people and their families, the medical institutes and social supportive departments were integrated and analyzed. It showed that the main reason of maternal deaths of Shanghai residents was poor knowledge and skills of medical staffs, accounting for 80. 0% of the deaths. While the main reasons of maternal deaths of migrating people were poor knowledge and skills, inappropriate attitude of the dead people and their families, which took up 54. 1% and 40. 1% respectively. Conclusions The MMR in Shanghai declined continuously from 2000 to 2009, especially for migrating population which reflected the interventions of maternal management in Shanghai were effective. Though obstetric hemorrhage was the first top cause of maternal death during past 10 years, it declined Sharply. 30% to 40% maternal deaths were avoidable if some conditions were created. However, in order to adapt the changes of main causes of maternal deaths and accomplish increasing service requirements, it is necessary to develop new service and management mode.     

Stillbirth, neonatal death and reproductive rights in Indonesia

Globally, newborn deaths account for two-thirds of all deaths in the first year of life and 40% of under-five mortality. As infant mortality declines, the proportion of neonatal deaths has been increasing because of the failure to address the causes. The data in this paper derive from a longitudinal study of motherhood and emotional well-being of women in Indonesia; 488 women were interviewed in late pregnancy, and 290 at six weeks post-partum. This paper reports on in-depth interviews with four women who reported a stillbirth and six who reported a neonatal or infant death. They were asked about their understanding of why their baby had died and the information, care and support given to them. The study suggests that maternal and child health clinics fail to protect and fulfill pregnant women's reproductive rights, specifically the right to information and care for themselves and their infants, informed consent, counselling and to be treated with respect. This can be achieved through training and education for health professionals and policymakers, and by educating women about their rights as patients. It is essential that countries with high infant and maternal mortality provide post-partum care that includes support for those who experience stillbirth and neonatal death, including information, counselling and home visits.     

HIV and maternal mortality

The majority of the 17 million women globally that are estimated to be infected with HIV live in Sub-Saharan Africa. Worldwide, HIV-related causes contributed to 19 000–56 000 maternal deaths in 2011 (6%–20% of maternal deaths). HIV-infected pregnant women have two to 10 times the risk of dying during pregnancy and the postpartum period compared with uninfected pregnant women. Many of these deaths can be prevented with the implementation of high-quality obstetric care, prevention and treatment of common co-infections, and treatment of HIV with ART. The paper summarizes what is known about HIV disease progression in pregnancy, specific causes of HIV-related maternal deaths, and the potential impact of treatment with antiretroviral therapy on maternal mortality. Recommendations are proposed for improving maternal health and decreasing maternal mortality among HIV-infected women based on existing evidence.

Epidemiologic transition in maternal mortality and morbidity: new challenges for Jamaica.

OBJECTIVE: Given interventions implemented in recent years to reduce maternal deaths, we sought to determine the incidence and causes of maternal deaths for 1998-2003. METHOD: Records of public hospitals and state pathologists were reviewed to identify pregnancy-related deaths within 12 months of delivery and determine their underlying causes. RESULTS: Maternal mortality declined (p=0.023) since surveillance began in 1981-83. The fall in direct mortality (p=0.0003) included 24% fewer hypertension deaths (introduction of clinical guidelines, reorganization of antenatal services) and 36% fewer hemorrhage deaths (introduction of plasma expanders). These improvements were tempered by growing indirect mortality (p=0.057), moving to 31% of maternal deaths from 17% in 1993-95. INTERPRETATION: Declines in direct mortality may be associated with surveillance and related improvements in obstetric care. Increased indirect deaths from HIV/AIDS, cardiac disease, sickle cell disease and asthma suggests the need to improve collaboration with medical teams to implement guidelines to care for pregnant women with chronic diseases.     

孕产妇危重事件发生率及防控策略研究进展

过去孕产妇死亡率是衡量一个国家或地区妇女健康状况和社会经济发展的重要指标之一。2019年美国疾病控制中心收集全国孕产妇死亡信息得出结论:如果采取行动,多达一半的孕产妇死亡是可预防的。随着2000年联合国“千年发展目标”的提出以及各国对孕产妇健康的重视,孕产妇死亡已经成为极低概率事件,而孕产妇危重事件发生率(severe maternal morbidity,SMM)已成为比孕产妇死亡率更常见和有用的产科护理指标。在美国,约50名经历SMM孕产妇中发生1例死亡。虽然孕产妇死亡率历来是孕产妇结局的关键指标,SMM的流行情况却可以为围生期健康提供更全面的信息,也是监测孕产妇结局的一种方法。同时,SMM通常是孕产妇死亡的先兆,作为导致孕产妇死亡的动态过程和前期指标,SMM对强化孕产妇管理、降低孕产妇死亡率有重要意义。许多国家开始将SMM作为评价产科质量的重要指标之一。防控SMM,除了常规策略外,避免医疗相关的延迟,使用孕产妇早期预警触发工具(MEWT)有重要临床价值。     

山东省2007~2013年孕产妇死亡率的变化及预测

目的:分析孕产妇死亡率的变化规律,为进一步降低孕产妇死亡率提供参考依据。方法:回顾调查分析2007~2013年山东省孕产妇死亡监测点资料,并进行自回归滑动平均模型死亡率预测。结果:7年孕产妇死亡率依次为20.91/10万、20.85/10万、22.24/10万、21.13/10万、20.59/10万、18.94/10万和16.80/10万,平均为19.53/10万,年平均下降率为3.58%;预测2014年孕产妇死亡率为14.11/10万。前3位死因为产科出血、妊娠合并心脏病、肺栓塞。分娩地点、死亡地点、孕产妇产前检查情况、家庭人均年收入及文化程度对其死亡有影响。评审结果显示,50.82%的死亡孕产妇是可避免的。结论:山东省孕产妇死亡率下降速度减慢,处于平台期。实现孕产妇死亡率进一步降低有赖于提高产科服务能力、提升社会经济水平、提高孕产妇及家属认知与识别能力等综合措施的共同干预。     

Does maternal obesity impact pregnancy-related deaths? Michigan experience

Obesity is a multifactorial non-communicable condition that has become a public health epidemic worldwide. The Fifth Millennium Development Goal established the goal of a 75% reduction in the maternal mortality ratio (MMR) between 1990 and 2015. Maternal mortality has been difficult to track over time. Obesity affects pregnancy in more than 50% of women of reproductive age in the state of Michigan; the potential impact of maternal obesity and pregnancy-related deaths (PRDs) has not been studied in Michigan. We conducted a secondary analysis of maternal death cases originally reviewed by the Michigan Maternal Mortality Review Committee from 2004 to 2006 seeking to evaluate the impact of maternal obesity on PRD. Two hundred and five maternal deaths occurred during the period of the study, 61 were classified as PRD. The observed occurrence of PRDs in the obese population was 36 cases while in the non-obese was 25 cases. The study showed a 3.7× risk of PRD in the obese parturient.     

Prevalence of Maternal Mortality and Clinical Course of Maternal Deaths in COVID-19 Pneumonia-A Cross-Sectional Study

IntroductionAfter initial studies suggested that pregnant women were not at a higher risk of complications due to COVID‐19 infection. Recent investigations from Sweden and the US have indicated that pregnant and postpartum women are at increased risk of severe complications associated with COVID‐19. This study aims to find out the prevalence of maternal mortality and the clinical course of maternal mortality cases due to COVID-19 pneumonia.MethodologyA cross-sectional study was conducted from May 1st, 2020, to April 30th, 2021, at Postgraduate Institute and YCM Hospital Pimpri Pune (Maharashtra), a dedicated COVID hospital during COVID pandemic. During study period, all pregnant women who were diagnosed to have COVID-19 infection by RT PCR/Rapid Antigen Test were admitted and were enrolled for the study.AimTo audit the maternal mortality due to COVID-19 infection.PrimaryTo estimate the prevalence of maternal mortality due to COVID-19 infection in obstetric patients.SecondaryTo systematically study and analyze the clinical course of infection in mothers who had mortality due to COVID-19 pneumonia. Data collected in standard format regarding Demography, clinical presentation, need for ICU/HDU, CXR findings, laboratory parameters and cases with maternal mortality were studied in detail to fulfill the study objectives.ResultsAmong 871 COVID-19 cases diagnosed during pregnancy, nine patients had maternal mortality due to covid pneumonia. There was no obvious obstetric cause for mortality in these cases. The prevalence of maternal mortality was 0.01 (1.03%). Cases with maternal mortality were mostly in 3rd Trimester (5 of 9 cases) and presented with moderate to severe illness with breathlessness and myalgia in all 9 cases, cough and fever in 7 out of 9 cases, Tachypneoa was noted in all patients. Saturation below 90 in 6 cases and below 94 in 3 cases. Chest X-ray showed bilateral lung affection in all 9 cases. Leukocytosis with raised N:L ratio was predominantly seen, thrombocytopenia noted in 5 cases and elevated levels of acute phase reactants and inflammatory markers such as CRP, S. ferritin, ESR, LDH, D-dimer and S. fibrinogen was observed. None of the study participants received vaccine for COVID-19.ConclusionsCOVID-19 pneumonia is an additional toll for maternal mortality. Obstetric patients in 2nd and 3rd trimester having COVID-19 infection with late presentation to hospital, moderate to severe disease (RR > 30 min), with raised inflammatory markers (N:L ratio, CRP, Ferritin, d-Dimer, etc.) at presentation, having bilateral lung affection are at risk of poor maternal outcome.
