uterine subinvolution

uterine subinvolution

Etymology: L, uterus + sub, under, involere, to roll up
delayed or absent involution of the uterus during the postpartum period. The causes of subinvolution include retained fragments of placenta, uterine fibromyomas, and infection. Regardless of the cause of the condition, it is characterized by longer and heavier bleeding after childbirth and, on pelvic examination, a larger and softer uterus than would be expected at that time. Treatment includes ergonovine given by mouth for 2 or 3 days, and, if an infection is present, an antibiotic. The hemoglobin or hematocrit is also evaluated, and iron is given if necessary. A follow-up examination is performed 2 weeks later. Also called partial involution.
