The grand multipara--an obstetric problem?

Abstract

At the Medical Central Department of Obstetrics and Gynecology in Sibenik over 1970-1991 period there were 26,116 deliveries (multiple births excluded), of which 254 (0.97%) occurred in grand multiparas (five and more deliveries). The authors have found that the number of grand multiparas decreased by 38.3% (P < 0.001) over the past eleven years. Control subjects were 7920 multiparas (two to four deliveries, 20-34 years of age, from the same period). In 84.3% of the cases grand multiparas were delivered of their fifth or sixth infant, and 68.5% were > or = 35 years of age. Spontaneous abortion occurred in 16.9%, and 14.2% had no antenatal visit. EPH gestosis (8.3%), glucose intolerance (9.9%), preterm delivery (8.3%) and meconium-stained amniotic fluid (15.0%) were more common in the grand multiparas, whereas cervical cerclage (5.4%) and 7-to-12-hour duration of labour (12.8%) were more common in the control group. No significant differences were found in weight gain, prolonged pregnancy, caesarean delivery, assisted breech and vacuum extraction between two groups. There was also no difference in the incidence of neonatal morbidity and congenital abnormalities between the grand multiparas and controls. Late fetal and early neonatal deaths in the grand multiparous and control group occurred in 1.18% and 1.57, respectively, resulting in a 2.75% overall perinatal death rate for both groups (P > 0.05). No case of maternal death or uterine rupture occurred in either group. The authors conclude that pregnancy and delivery in grand multiparas are at higher risk due to poorer antenatal care and advancing maternal age.(ABSTRACT TRUNCATED AT 250 WORDS)
