Physiology in Pregnancy Flashcards
Breast changes in pregnancy
Increased size and vascularity - warm, tense and tender
Increased pigmentation of the areola and nipple, 2ry areola appears
Montgomery tubercles appear on the areola
Colostrum-like fluid can be expressed from the end of the third month
Intrapartum cardiovascular changes
Autotransfusion of contractions
Pain - increasing catecholamines
CO increases by 10% in labour and by 80% in 1st post delivery hour
How long does it take for cardiovasculature to return to normal postpartum?
By 3 months (mostly)
Hg Platelets Urea Creatinine Urate in lab tests
Decreased
Urate increases with gestation
WCC
ESR
Increased
CRP
Unchanged
What is ESR measured for?
Erythrocyte sedimentation rate
Results are reported as how many millimetres of clear plasma are present at the top of the column after one hour. Normally, red cells fall slowly, leaving little clear plasma. Increased blood levels of certain proteins (such as fibrinogen or immunoglobulins, which are increased in inflammation) cause the red blood cells to fall more rapidly, increasing the ESR
Indirect measure of inflammation
Why is CRP measured?
C-reactive protein
Produced by liver in response to inflammation
