Involution is a process that 2. The breakdown of living cells or catabolism: process of necrosis of the

condition. The focus is on
the uterus (uterine Subinvolution: failure of uterus to return to prepregnant size caused by
involution) or the return to or retained placental fragments and/or infection
the reduction of the uterus'
Subinvolution: failure of uterus to return to prepregnant size caused by

prepregnant size. The
descent of the uterus is the
key part of the nurse's
assessment in order to
determine uterine
involution.
Early PPH occurs in first 24° with blood loss of >500 mLs for vaginal;
Uterine involution begins

immediately after delivery of
the placenta. Decrease in 3 major causes:

involves 3 processes:

Uterine atony- defined as the lack of muscle tone resulting in failure of the
uterine muscle to contract after the placenta is expelled.
