8.5 Subinvolution
Sub involution is incomplete return of the uterus to its pre
pregnant size and shape. With subinvolution, at a 4 or 6 week
post portal risk, the uterus is still enlarged and soft and the
woman still has a lochia discharge. Sub involution may result
from.
- A small retained placental fragment
- A mild endometritis or
- An accompanying problem such as a myoma that is
interfering with complete contraction.
Treatment
- Oral administration of methyl ergotamin 0.2mg Q 10 hours
to improve uterine time and complete involution.
- An oral antibiotic if the uterus is tender on palpation
N.B. Be certain that women know at discharge from a
health care facility the normal process of involution
and lochial discharge.
