[The effect of maternal age on the incidence of and indications for cesarean section in primiparae]. / Vliianie na maichinata vuzrast vurkhu chestotata i indikatsiite za sectio caesarea pri purvorazhdashti.

The authors aim to evaluate the effect of the maternal age on the frequency and indications for cesarean section in primiparas. Indications for abdominal deliveries of 1020 women are analyzed. Three age groups are formed: first group--up to 29 years of age, second group--up to 30-34 years of age, and third group--up to 35 and more years of age the so called aged primiparas (AP). The causes for operation are divided into ten basic groups. The indicated increased frequency with advancement of age is due mainly to: fetal distress, grave obstetric history, extragenital pathology, broad and combined indications. Their relative part in AP is respectively; 23.21%, 37.50%, 16.96%, 15.17% and 33.03%. A critical attitude is expressed to the unjustified increased frequency of the operation especially after 35 years of age (during 1987 up to 85.71%). The authors take a firm stand on their concept that the age of primiparas irrespective of years could not be a single cause for cesarean section.
