Reproductive System
• Uterus
– Lochia

– Old blood, serum, leukocytes, tissue debris
– Brown or pink color for about 22 to 27 days (?)
![Page 10: Postpartum Physiological Adaptation](https://reader034.vdocuments.us/reader034/viewer/2022052106/6287b5d7b1da591c5a689698/html5/thumbnails/10.jpg)

Reproductive System
• Uterus
– Lochia
• Gush of blood when stand up from lying position
![Page 12: Postpartum Physiological Adaptation](https://reader034.vdocuments.us/reader034/viewer/2022052106/6287b5d7b1da591c5a689698/html5/thumbnails/12.jpg)
Lochial bleeding Nonlochial bleeding
Lochia usually trickles from the
vaginal opening. The steady flow
is greater as the uterus contracts
If the bloody discharge spurts
from the vagina, there may be
cervical or vaginal tears in
addition to the normal lochia
A gush of lochia may result as
the uterus in massaged. If it is
dark in color, it has been pooled
in the relaxed vagina, and the
amount soon lessens to a trickle
of bright red lochia (in the early
postpartum)
It the amount of bleeding
continues to be excessive and
bright red, a tear may be the
source.

Reproductive System
• Uterus
– Endometrial regeneration
• Endometrium is restored during the third week
• subinvolution
![Page 14: Postpartum Physiological Adaptation](https://reader034.vdocuments.us/reader034/viewer/2022052106/6287b5d7b1da591c5a689698/html5/thumbnails/14.jpg)
Reproductive System
