Best pelvis
Gynecoid
Female Bony Pelvis
Four bones-
2 innominate two side bones/hip bones
The ilium,
the ishium the pubis and the Sacrum.
Pelivic diaphram
- Dilation during birth
- Returns to pregnancy condition after birth
- Deep facscia of levater coccygeal muscles form the pelvis.
Premonitory signs of Labor
- Braxton Hicks
- Lightening
- Increased vaginal secretions
- Bloody show/mucous plug
- Energy spurt
True Labor
Progressive dilation and effacement
Regular contractions
- ubcreasubg ub frequency, duration, intensity
- Intensity increases with ambulation
False Labor
Ambulation, changes of position, resting, or hot bath or shower.
A women with Gynecoid pelvis has
LESS COMPLICATIONS
Anthropoid Pelvis
Is also good for labor.
Measuring a womens pelvis
Is just an estimation
Pelvic floor is made of:
Musculature to overcome force of gravity.
Pelvic Diaphragm
- Dilation during birth
- Returns to prepregancy condition after birth
- Deep fascia of levator ani, cocygeal muscles form this part of the pelvis.
Questions to ask patient if she calls and says she is experiencing LABOR
- If she had a contraction and how often
- Did your water break.
- Pain location, stay or does it change or not
- Where is pain located, does it stay the same or does it get worse.
- Is baby moving normally.
WHEN WOMEN HAS FALSE LABOR IT can be RELIEVED by:
- Change in position
- Hot bath or showers.
- Rest
True Labor
- Regular contractions
- Pain usually starts in back, radiates to abdomen
- Pain not relieved by ambulation or by resting.
- Contractions do not decrease
We need to assess
Fetal and maternal status
False Labor
- Lack of cervical effacement and dilation
- Irregular contractions do not increase in frequency, duration, and intensity
- Contractions mainly in lower abdomen and groin
- Pain may be reduced by amubulation, changes of position, resting, or hot bath or shower.

Ask women to cough….
and FLUID DROPS…Then YES she has ruptured….
Please keep in mind you want to get as much information as possible because women can develop
INFECTION
If a women has GIVEN BIRTH MANY TIMES
She will go faster…than a women that is more dilated but on her first birth.
Physiological changes during the birth process
Cervical changes
- Effacement-thinning and shortening
- Dilation-Opening
