Objective: To know the contribution of high risk pregnancy to perinatal mortality and identify the related factors. Method: Observational, retrospective, epidemiological and descriptive study of 298 perinatal deaths occurred during 1999-2001. As an instrument for identification of risk we use a form with factors and semi-quantitative grades previously validated. Setting: Departamento de Obstetricia y Ginecologia, Hospital "Dr. Adolfo Prince Lara" de Puerto Cabello, Estado Carabobo. Results: Age show a general incidence of 89.39 % (177/298) and parity 66.77 % (199/298). Risk factors in obstetrical history had a global incidence of 52.34 % (156/298); abortion 45.51 % and previous cesarean section 28.21 %. Medical pathology presented a general incidence of 74.83 % (223/298). In obstetrical pathology the global incidence was 52.34 % (156/298); were determinant the pregnancy induced hypertension 34,61 %, premature labor 28.21% and II-III trimester hemorrhage 22.44%. Maternal risk intrapartum and placental factors had a global incidence of 47.98 % (143/298), with premature detachment of placenta in the first place (29.37 %). Fetal factors were 52.34 % (156/298). From the 298 perinatal deaths 69.13 % (206/298) were high risk pregnancies; 27.85 % (83/298) low risk and 3.02 % (9/298) no risk. There were 56.38 % (168/298) fetal deaths and 43.62 % (130/298) neonatal deaths; fetal death was predominant in the three groups. Conclusion: Risk pregnancy determinately contribute to perinatal mortality. The identification of factors adequately managed could be a valid alternative for decreasing the mortality.
