grand multiparity
A condition where a woman has delivered five or more viable pregnancies, associated with increased obstetric risks.
Full Definition
Grand multiparity traditionally refers to women who have completed five or more pregnancies resulting in viable births (≥20 weeks gestation or ≥500g birth weight). This designation is clinically significant because grand multiparous women face increased risks during pregnancy and delivery, including postpartum hemorrhage, placental abnormalities, malpresentation, and uterine rupture. The risks are attributed to decreased uterine muscle tone from repeated pregnancies and potential complications from previous deliveries. Some institutions use alternative definitions such as 10 or more previous deliveries for 'great grand multiparity.' Risk assessment and enhanced monitoring protocols are typically implemented for grand multiparous patients throughout pregnancy and labor.
Usage
Usage note: Typically defined as five or more previous viable deliveries, though definitions may vary by institution.
