[Perinatal mortality].

Eighty six cases of perinatal mortality at Hospital de Ginecoobstetricia, Garza García, N.L. Subsecretaría Estatal, from january, 1992 to December, 1993, were reviewed. Perinatal mortality was 12.0 by one thousand births, less than in other reports. The highest incidence was in young patients, 20 to 29 years old, with 47.7% and with parity of 1 to 3, 80.2%; highest frequency in term pregnancies, 37 to 42 weeks, 39.6%; 35% of the products with weight over 2,500 g; and 65% with lesser weight; fetal death occurred most frequently during pre-partum, 55.8%, and less during intra-partum, 19.8%. Most frequent causes of peri-natal death were placental failure, 27.9% and fetal immaturity, with 24.4%. It is concluded that an adequate pre-natal control and delivery surveillance produce a diminution in fetal mortality.
