“…As a result, we chose to use echocardiography (echo), which has recently been validated against thermodilution in pregnancy and has been suggested as a reference for the validation of other CO techniques in pregnant women. 18 Bland-altman analysis Our results suggest that NICOM V R is a valid method for assessing CO in the pregnant population when compared with echocardiographically measured CO. The mean percentage error obtained in our study was 26%, which is less than the recommended cut-off of 30%.…”

“…Echocardiography and Doppler ultrasound have been widely used for the assessment of CO during pregnancy [3][4][5][6][7][8][11][12][13][14][15][24][25][26][27][28][29][30]32,56,[82][83][84] , and have proved to be reliable when compared with the invasive techniques 3,85,86 . The general availability of ultrasound and its low cost, portability and true non-invasiveness, make TTE an ideal method for rapid hemodynamic assessment in pregnancy.…”

Cardiac output (CO), along with blood pressure and vascular resistance, is one of the most important parameters of maternal hemodynamic function. Substantial changes in CO occur in normal pregnancy and in most obstetric complications. With the development of several non‐invasive techniques for the measurement of CO, there is a growing interest in the determination of this parameter in pregnancy. These techniques were initially developed for use in critical‐care settings and were subsequently adopted in obstetrics, often without appropriate validation for use in pregnancy. In this article, methods and devices for the measurement of CO are described and compared, and recommendations are formulated for their use in pregnancy, with the aim of standardizing the assessment of CO and peripheral vascular resistance in clinical practice and research studies on maternal hemodynamics.

“…Studies in ICU settings looking at central venous access rates range from 12 54 to 15% 55 of admissions to 50%, 56,57 with intraarterial access rates of up to 70 to 75%. 56,58 There is an increasing body of evidence on the utility of echocardiography in critically ill pregnant women, 59,60 and women admitted with cardiorespiratory or circulatory compromise should have an echocardiogram to exclude structural abnormalities or impairment of cardiac function. In the setting of maternal collapse, echocardiography may be helpful to diagnose problems such as pulmonary embolism.…”

Pregnant women represent a small subset of all intensive care unit (ICU) admissions and may require intensive care for "obstetric" or "nonobstetric" reasons. Women may be admitted to the ICU at any stage of pregnancy or in the postpartum period. Pregnancy may be discovered at the time of admission to the ICU. Pregnancy impacts on ICU care in a variety of ways and requires a multidisciplinary approach to management. Pregnancy is associated with considerable physiological changes that affect most organ systems, including an expansion in blood volume, an increase in minute ventilation, and an increased risk of thrombosis. The enlarging uterus may be associated with mechanical complications due to compression and displacement of other structures. The growing fetus places considerable demands upon the mother, being reliant on maternal systems for oxygenation, nutrition and disposal of carbon dioxide, and other waste products. This "second patient" must be considered when managing the pregnant woman. Optimal management of the mother usually constitutes best treatment for the fetus. Maternal shock and physiological disturbance, medications, and ionizing radiation from diagnostic imaging may have harmful effects on the unborn child. Delivery of the fetus for either maternal or fetal indications may be necessary and should be planned for, even if considered unlikely to be required. Care of the postpartum woman has its own challenges, including managing lactation and facilitating mother/infant contact. In this article, the general care aspects of ICU treatment of the pregnant woman will be discussed, including monitoring, physiological target setting, and general supportive care.
