High-risk pregnancy and perinatal losses

Objective. To evaluate the effectiveness of predicting perinatal losses, by applying the table “Risk factors during pregnancy and childbirth” drawn up more than 40years ago. Subjects and methods. A case control study to assess risk factors was conducted in 664 pregnant women. A study group consisted of 307 women with perinatal losses (antenatal (n = 159) and intrapartum (n = 49) fetal deaths; 99 newborns died in the first 168 hours of life). A control group included 357 (53.8%) women without perinatal losses. Results. Analysis ofsocio-biologicalfactors, obstetric/gynecological histories, and maternal extragenital pathology revealed no statistically significant differences in the comparison groups. Noise factors made the assessment of the risk for the course of pregnancy difficult. Conclusion. The table-based prognostic model has low sensitivity and is unable to identify a group at high risk for perinatal losses.
