Abstract
OBJECTIVE To assess the performance of the Acute Physiology and Chronic Health Evaluation II (APACHE II) mortality prediction model in pregnant and recently pregnant women receiving critical care in low-, middle-, and high-income countries during the study period (1985-2015), using a structured literature review. DATA SOURCES Ovid MEDLINE, Embase, Web of Science, and Evidence-Based Medicine Reviews, searched for articles published between 1985 and 2015. STUDY SELECTION Twenty-five studies (24 publications), of which two were prospective, were included in the analyses. Ten studies were from high-income countries (HICs), and 15 were from low- and middle-income countries (LMICs). Median study duration and size were six years and 124 women, respectively. DATA SYNTHESIS ICU admission complicates 0.48% of deliveries, and pregnant and recently pregnant women account for 1.49% of ICU admissions. One quarter were admitted while pregnant, three quarters of these for an obstetric indication and for a median of three days. The median APACHE II score was 10.9, with a median APACHE II-predicted mortality of 16.6%. Observed mortality was 4.6%, and the median standardized mortality ratio was 0.36 (interquartile range 0.23 to 0.73). The standardized mortality ratio was < 0.9 in 24 of 25 studies. Women in HICs were more frequently admitted with a medical comorbidity but were less likely to die than were women in LMICs. CONCLUSION The APACHE II score consistently overestimates mortality risks for pregnant and recently pregnant women receiving critical care, whether they reside in HICs or LMICs. There is a need for a pregnancy-specific outcome prediction model for these women.

Abstract
A 1 year prospective analysis of all critically ill obstetric patients admitted to a newly developed dedicated obstetric intensive care unit (ICU) was done in order to characterize causes of admissions, interventions required, course and foetal maternal outcome. Utilization of mortality probability model II (MPM II) at admission for predicting maternal mortality was also assessed. During this period there were 16,756 deliveries with 79 maternal deaths (maternal mortality rate 4.7/1000 deliveries). There were 24 ICU admissions (ICU utilization ratio 0.14%) with mean age of 25.21±4.075 years and mean gestational age of 36.04±3.862 weeks. Postpartum admissions were significantly higher (83.33% n=20, P<0.05) with more patients presenting with obstetric complications (91.66%, n=22, P<0.01) as compared to medical complications (8.32% n=2). Obstetric haemorrhage (n=15, 62.5%) and haemodynamic instability (n=20, 83.33%) were considered to be significant risk factors for ICU admission (P=0.000). Inotropic support was required in 22 patients (91.66%) while 17 patients (70.83%) required ventilatory support but they did not contribute to risk factors for poor outcome. The mean duration of ventilation (30.17±21.65 h) and ICU stay (39.42±33.70 h) were of significantly longer duration in survivors (P=0.01, P=0.00 respectively) versus non-survivors. The observed mortality (n=10, 41.67%) was significantly higher than MPM II predicted death rate (26.43%, P=0.002). We conclude that obstetric haemorrhage leading to haemodynamic instability remains the leading cause of ICU admission and MPM II scores at admission under predict the maternal mortality.

Abstract
BACKGROUND Management of high risk obstetric patients. AIM The present study was conducted to evaluate the primary causes of the admission of obstetric patients to Intensive Care Unit (ICU), the presence of co-morbid diseases, outcome of such patients, their survival rate as well as the factors which contribute to the maternal mortality. SETTINGS AND DESIGN A retrospective study was conducted in the Department of Obstetrics and Gynaecology and Anaesthesiology/ICU of our Institute. MATERIALS AND METHODS Sixty-one obstetric patients, who were admitted to ICU between 20 December 2006 and 31 January 2010, were evaluated for various factors responsible for their admission as well as their outcome. STATISTICAL ANALYSIS At the end of study, the data were arranged systematically and subjected to statistical analysis using nonparametric tests and P value <0.05 was considered significant. RESULTS Majority of the 61 patients admitted in ICU were referred from the peripheral health centers, smaller nursing homes/hospitals and some even without proper primary care and mainly comprising uneducated and rural population. Hemorrhage, pregnancy induced hypertension, cardiac diseases, respiratory insufficiency and sepsis were the main causes for admission. A total of 18 patients among 61 died during their ICU stay in the hospital. CONCLUSIONS In the developing countries, high risk pregnancy should be managed at peripheral centers with proper facilities, antenatal visits and timely referral. The intensive care help should be reserved for very high risk pregnancies with co-morbid diseases.

Abstract
The objective of this retrospective study was to investigate the indications, interventions and clinical outcome of pregnant and newly delivered women admitted to the multidisciplinary intensive care unit at the King Abdullah University Hospital in Jordan over a 7-year period from January 2002 to December 2008. The collected data included demographic characteristics of the patients, mode of delivery, pre-existing medical conditions, reason for admission, specific intervention, length of stay and maternal outcome. A total of 43 women required admission to the intensive care unit (ICU), which represented 0.37% of all deliveries. The majority (95.3%) of patients were admitted to the ICU postpartum. The most common reasons for admissions were (pre)eclampsia (48.8%) and obstetric haemorrhage (37.2). The remainder included adult respiratory distress syndrome (6.9%), pulmonary embolism (2.3%) and neurological disorders (4.6%). Mechanical ventilation was required to support 18.6% of patients and transfusion of red blood cells was needed for 48.8% of patients. There were three maternal deaths (6.9%). A multidisciplinary team approach is essential to improve the management of hypertensive disorders and postpartum haemorrhage to achieve significant improvements in maternal outcome. A large, prospective study to know which women are at high risk of admission to the intensive care units and to prevent serious maternal morbidity and mortality is warranted.

Abstract
PURPOSE To determine the incidence and characteristics of pregnant and postpartum women requiring admission to an intensive care unit (ICU). METHODS Medline, PubMed, EMBASE and CINAHL databases (1990-2008) were systematically searched for reports of women admitted to the ICU either pregnant or up to 6 weeks postpartum. Two reviewers independently determined study eligibility and abstracted data. RESULTS A total of 40 eligible studies reporting outcomes for 7,887 women were analysed. All studies were retrospective with the majority reporting data from a single centre. The incidence of ICU admission ranged from 0.7 to 13.5 per 1,000 deliveries. Pregnant or postpartum women accounted for 0.4-16.0% of ICU admissions in study centres. Hypertensive disorders of pregnancy were the most prevalent indication for ICU admission [median 0.9 cases per 1,000 deliveries (range 0.2-6.7)]. There was no difference in the profile of ICU admission in developing compared to developed countries, except for the significantly higher maternal mortality rate in developing countries (median 3.3 vs. 14.0%, p = 0.002). Studies reporting patient outcomes subsequent to ICU admission are lacking. CONCLUSIONS ICU admission of pregnant and postpartum women occurs infrequently, with obstetric conditions responsible for the majority of ICU admissions. The ICU admission profile of women was similar in developed and developing countries; however, the maternal mortality rate remains higher for ICUs in developing countries, supporting the need for ongoing service delivery improvements. More studies are required to determine the impact of ICU admission for pregnant and postpartum women.

Abstract
CONTEXT During pregnancy, the two leading causes of admission in intensive care are preeclampsia and obstetric haemorrhage. However, there are few studies about preeclamptic patients admitted in intensive care. Our purpose was to determine the outcome of pregnancies with preeclampsia and/or HELLP syndrome admitted in intensive care. METHODS We performed a retrospective study between March 1996 and April 2005 in a level III maternity. 533 patients were managed with preeclampsia and/or HELLP syndrome during this period. We compared patients admitted in intensive care with patients who did not require admission in intensive care. RESULTS Sixty six patients (12,4%) with preeclampsia and/or HELLP were admitted in intensive care. Severe HELLP syndrome, eclampsia, neurological troubles and acute pulmonary oedema were the four leading causes of admission. The mean duration of admission was 3, 2+/-2,9 days. Mean age of the patients (28, 2+/-5,8 vs. 29,0+/-5,8 years, NS) and number of primiparous (71, 2% vs 66,6%, NS) were similar between the two groups. The mean gestational age of delivery was reduced when patients were needed admission in intensive care (29,8+/-3,9 weeks of gestation versus 32,5+/-4,4, p<0,001). 77, 3% of babies survived in the intensive care group compared with 90,4% in the other group (p<0,01). CONCLUSION The short-term outcome of patients admitted in intensive care for preeclampsia or HELLP syndrome is generally good. However, neonatal morbidity and mortality remained important when women needed management in intensive care.

Abstract
Remifentanil has been proposed as the most suitable systemic opioid for use in obstetrics. Although the onset and offset are rapid, it cannot achieve maximum effect within the time period of a single uterine contraction. Nevertheless, it provides worthwhile analgesia mainly for the first stage of labor with consistently high maternal satisfaction. Maternal oxygen desaturation limits the dose and suitable monitoring during use is advised. As an adjunct to general anesthesia, it is successful in blunting responses to airway manipulation and providing hemodynamic stability in high-risk women. Neonatal effects when used in labor are minimal, but when combined with general anesthesia neonatal depression is unpredictable and more likely with an infusion dose greater than 0.1 microg/kg/min.

Abstract
INTRODUCTION Obstetric patients are generally young and healthy. However, the potential for catastrophic complications is real, and despite the therapeutic advances of the last few decades, maternal morbidity and mortality continue to occur. This may be related to the pregnancy itself, aggravation of a preexisting illness, or complications of the (operative) delivery. PURPOSE The purpose of this review is two-fold: first, to provide an update on currently available reports pertaining to important critical care issues of the obstetric patient population and, second, to present current comprehensive treatment options for preeclampsia and massive obstetric hemorrhage because both are responsible for the majority of maternal mortality and morbidity worldwide. RESULTS The most common reasons for intensive care unit admission are hypertensive disorders and massive obstetric hemorrhage. Timely delivery and prompt initiation of antihypertensive therapy for severe hypertension form the mainstay of care in preeclampsia. Restoration of circulating blood volume and rapid control of bleeding and impaired coagulation are the main factors in the management of massive obstetric hemorrhage. Puerperal morbidity has become the main topic of quality of care issues in maternity care. Although the Acute Physiology and Chronic Health Evaluation II score is commonly used in the intensive care unit, it does not seem to be appropriate for pregnant women because it overestimates their mortality rates. A high-dependency care unit suits the needs for at least half of the obstetric patient population in need of higher acuity care and will save considerable cost. CONCLUSION Emphasis on early detection of maternal problems and prompt referral to tertiary centers with intensive care unit facilities to provide optimum care of the circulation, blood pressure, and respiration at an early stage could minimize the prevalence of multiple organ failure and mortality in critically ill obstetric patients.

Abstract
Obstetric patients are a small but important group of patients in the intensive care unit (ICU). Their problems are unique and need specialized attention. Decision making may be confounded by physiologic changes in pregnancy. In developed countries with good antenatal care, comparatively fewer obstetric patients are admitted to ICUs, but the maternal mortality rate remains high in the developing countries. Medical disorders and organ dysfunction caused by critical illness of pregnancy differ from region to region. With improvement in antenatal care, the number of ICU admissions for obstetric disorders would decline in developing countries; however, this number may increase gradually in developed countries because of increasing maternal age and pregnancies in women with complicated chronic medical disorders.
