When is the fetus considered full term? |
Btn 37-42wks |
|
|
What events preceed labor in the 3rd trimester |
1. Plug of mucus & blood ( bloody show) OR 2. Amniotic sac rupture (water breaking) Eithsr of the 2 can trigged true labour contractions |
|
|
What's the difference btn true labour contractions from false labour contractions( braxton-hicks contractions) ? |
True labour contractions progress in frequency, duration & intensity |
|
|
How long does labour last from true contractions to delivery? |
12-18hr for prime gravida & 6-9hrs for multipara |
|
|
Stages of Labour? |
-1st stage *latent phase- until cervix dialates to 6cm, & effaces to 80% *active phase- with intense contractions & cervix dialates to 10cm & effaces to 100%. The amniotic sac ruptures at this point if it hasn't already -2nd stage Involves Delivery of the baby that depends on the 3P's (Power, passenger, passage) There are few factors that determine how easy the passage is; *fetal size (fetal head) *fetal attitude (refers to the way the fetal body is flexed, normally fully flexed with the smallest diameter being the suboccipitobregmatic diameter presenting at the pelvic inlet) *fetal lie (longitudinal lie is ideal) *fetal presentation (the 1st fetal part to descend into the pelvis), cephalic presentation, vertex cephalic is when the fetus presents w the head & fully flexed( which is ideal), there is also breech and shoulder presentations. To pass thru the pelvis the fetus makes several positional changes (cardinal movements of Labour) 1. Decent- downward movt. Of the fetus to the pelvic inlet, the degree of decent is called fetal station (-5, 0, +5 in relation to the ischial spine) 2. Engagement (at station 0) 3. Flexion 4. Internal rotation 5. Extension (+4 station) 6. Restitution ( head externally rotates after it's delivered) 7. Expulsion (delivery of the whole body) -3rd stage Delivery of the placenta -4th stage Recovery |
