LABOR and BIRTH Flashcards
What is the most valid SIGN that a woman is in LABOR?
The onset of REGULAR-PROGRESSIVE CONTRACTION
What is DILATION?
The OPENING of the CERVIX that goes from 0 - 10 cm.
What is EFFACEMENT?
THINNING of the CERVIX (goes from thick to 100%)
A woman begins labor from thick and close /thick to zero cm.
What is STATION?
The RELATIONSHIP of the FETAL PRESENTING PART to mothers’ ISCHIAL SPINE
What is ISCHIAL SPINE?
Is the SMALLEST DIAMETER through which the baby has to fit to be born vaginally. The NARROWEST part of the PELVIS.
What does NEGATIVE STATION mean?
The PRESENTING PART is ABOVE the NARROWEST part of the PELVIS [-1; -2]
(Positive Station/numbers [+3; +4] means the baby’s presenting part is below/made it through the NARROWEST PART of the Pelvis)
-1,-2,-1,-2 for 17 hrs., after FULLY DILATED and EFFACED
= Head too big - C-Section
+4 +3; +4 +3 for 17 hrs. = Vaginal Delivery
Remember: “Negative numbers are negative news” - baby way up and not coming down
“Positive numbers are positive news” - Baby’s coming out, it won’t be long now
what STATION is ENGAGEMENT?
Station ZERO (meaning presenting part is at the ISCHIAL SPINE)
What is LIE?
The RELATIONSHIP between the SPINE of the MOTHER and the SPINE of the BABY (If mom spine and baby’s spine are PARALLEL = GOOD; If mom’s spine and baby’s spine form an inverted “T” shape = Trouble=Transverse
What is PRESENTATION?
PART of the BABY that ENTERS the BIRTH CANAL first
This is where you get the “Alphabet Soups” = ROA; ROP; LOA; LOP; RMP; RSA; RSP (Fetal Position) e.g. ROA - Right Occipital Anterior
