ObjectiveTo review the clinical characteristics and outcomes of critically ill obstetrical patients and to determine the outcome predictability using the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system.MethodsA retrospective data collection of all obstetrical patients (n = 49) admitted for more than 24 hours to the Intensive Care Unit at Kwong Wah Hospital from 1988 to 1995 was conducted. Demographics, obstetric data, preexistent medical problems, diagnosis, days staying in the ICU and ICU related data were recorded for each patient.ResultsObstetric admissions to ICU during the study period represented 0.12% of all deliveries during this period. There was a predominance of postpartum admissions and obstetric diagnosis responsible for the patients' critical illness. Massive postpartum haemorrhage was the single most common cause of ICU admission, representing 53.0% of all patients. Preeclampsia and eclampsia (14.3%), anaesthesia related complications (14.3%), and medical diseases complicating pregnancy (14.3%) were the other common disease categories for ICU admission. Two cases (4.1%) of surgical disease complicating pregnancy were admitted. The maternal mortality rate was 5.1 deaths per 100,000 total births, or 2 maternal deaths in 39,354 total deliveries in this study period. All deaths were due to nonobstetric causes. The perinatal mortality rate was 10.0% (5 cases) in this study group.ConclusionsWhen applying the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system in predicting the final outcome in this group of obstetric patients, we found that our obstetric patients requiring intensive care had a better outcome than predicted, as expressed by a low mortality ratio (0.25).
