Recourse to the intensive care unit (ICU) for obstetric complications is relatively rare. However, in low-resource countries the technical and organizational capacities required for hospital management of serious complications of pregnancy are often limited. The aim of the present study was to determine the occurrence of third trimester obstetric admissions to an ICU in Morocco over a 4-year period, and to identify the associated obstetric pathologies.A retrospective study covering the 4-year period from June 1, 2007, to June 1, 2011, was conducted at the multipurpose ICU of Al Farabi regional hospital in Oujda, Morocco. Inclusion criteria were women who had been admitted to the ICU in the third trimester of pregnancy (over 28 weeks) or the early postpartum period (b7 days after delivery), who were free of pre-existing comorbidities (arterial hypertension, diabetes, and cardiopathy).There were 29 300 deliveries during the study period. A total of 217 (0.74%) obstetric patients were admitted to the ICU (7.4 per 1000 deliveries), including 157 (0.53%) patients admitted in the third trimester or early postpartum period (5.3 per 1000 deliveries). The main indications for admission to the ICU were severe preeclampsia/eclampsia, obstetric hemorrhage, and sepsis. Of the 157 admissions, 144 met the criteria and were included in the study. This constituted 6.1% of the 2346 total ICU admissions. There were 14 (9.7%) maternal deaths among the 144 women admitted to the ICU in the third trimester of pregnancy or the early postpartum period.The mean age of the 144 patients was 29 ± 7 years. Absence of prenatal medical care was observed in 83 (57.6%) patients and 77 (53.5%) were primiparous. Singleton pregnancy occurred in 139 (96.5%) patients and emergency cesarean delivery was performed in 111 (77.1%). The obstetric complications associated with admission to the ICU are given in Table 1. A total of 88 (61.1%) patients had a favorable outcome and were transferred to the maternity department within 72 hours. A total of 42 (29.1%) patients developed obstetric complications other than the pathologies that necessitated their initial admission.The reported incidence of obstetric admissions to ICUs varied from 0.22%-1.54% in high-resource countries and 0.37%-0.6% in low-resource countries [1][2][3][4][5]. Admissions in the third trimester of pregnancy represent more than two-thirds of the total obstetric admissions to the ICU [1-5]. Hypertensive disorders and obstetric hemorrhage are the predominant causes of such admissions [1][2][3][4][5].
