Background: The incidence of multiple pregnancies has increased on the last decade resulting in a rise of premature and underweight newborns infants, with increase of the perinatal morbidity and mortality.
Objective: To determine the impact of perinatal mortality of multiple pregnancies in the total perinatal mortality.
Patients and method: perinatal mortality rate of multiple pregnancies treated in the Unidad Médica de Alta Especialidad No. 23, Monterrey, Nuevo León (Mexico) were analized, from 2002 to 2008. The prevalence of multiple pregnancies, the rate of premature births, the incidence of low-birth weight products and perinatal mortality was estimated. The difference between overall mortality and multiple pregnancy rate was measured by χ2.
Results: Of the 144.114 births, there were 1,076 (0.8%) fetal deaths and 1,617 (1.10%) neonatal deaths. There were 110 high-order fetal pregnancies (more than three fetuses): 92 triplets, 14 quadruplets, 3 quintuplets and 1 sextuplet, producing a total of 353 newborns. Multiple pregnancies represent 2.8% (59/2,093) of the total perinatal mortality (p = 0.3). 79.9% (1,674/2,093) of the total perinatal mortality were newborns weighing less than 2,500 g. In the group of multiple pregnancies, all perinatal deaths occurred in products weighing less than 2,500 g.
Conclusions: The perinatal mortality of multiple pregnancies does not impact significantly overall perinatal mortality.

Key words: perinatal mortality, multiple pregnancies.
