Need for maternal critical care in obstetrics: a population-based analysis.
The purpose of this study was to note potential obstetric risk factors leading to maternal intensive care and to estimate the frequency, costs and outcomes of management. In a cross-sectional study of intensive care admissions in Kuopio from March 1993 to October 2000, 22 consecutive obstetric patients admitted to a mixed medical-surgical intensive care unit were followed. We recorded demographics, admitting diagnoses, APACHE II score, clinical outcomes and treatment costs. The overall need for maternal intensive care was 0.9 per 1000 deliveries during the study period. The mean age (+/-SD) of the patients was 31.7 (+/-6.6) years and the APACHE II score 10.8 (+/-6.2). The most common admission diagnoses were obstetric haemorrhage (73%) and pre-eclampsia-related complications (32%). The duration of ICU stay was 5.8 days (range 1-31) and one of the 21 patients died in the intensive care unit (4.5%). The total cost of intensive care was in the order of USD 5000 per patient. Very few obstetric patients develop complications requiring intensive care. Although several risk factors associated with maternal intensive care were documented, most cases occurred in low-risk women, which implies that the risk is relevant to all pregnancies. Long-term morbidity was rare, and collectively the outcome of intensive care was good. Further research is needed to determine effective approaches in prevention, such as uterine artery embolization.
