Conduct of Normal Labor and Delivery Flashcards
2 Poles
Cephalic, Podalic
Most dependent part of the fetus
Fetal Presentation
Cephalic presentation subtypes and their corresponding presenting parts/AP diameters
1) Vertex/Occiput - SOB (9.5 cm)
2) Military/Sinciput - OF (11-12 cm)
3) Brow - VM/OM (13.5 cm)
4) Face - SMB (9.5 com)
Breech presentation subtypes and their corresponding presenting parts/AP diameters
1) Frank - Sacrum
2) Complete - Sacrum
3) Incomplete - Sacrum, Foot
Shoulder presentation subtypes and their corresponding presenting parts/AP diameters
1 only:
Shoulder/Acromion, Arm, Trunk
Characteristic posture assumed by the fetus in utero
Fetal Attitude
Abnormal fetal attitude
From vertex to face (progressive change); vertebral column becomes concave from convex
Relation of a given portion of the presenting part to the ant., post., or transverse portion of the maternal pelvis
Fetal Variety
When is a vaginal examination an acceptable procedure for diagnosing fetal presentation and position?
At the onset of labor and cervical dilatation
When is a UTZ NOT anymore a reliable procedure for diagnosing fetal presentation and position?
At the onset of labor and cervical dilatation, when fetus is engaged
Four Movements of Vaginal Examination (in order!)
1) I.D. presenting part
2) Sagittal Suture Tracing
3) I.D. fontanelle position
4) Station
When is a UTZ an acceptable procedure for diagnosing fetal presentation and position?
If the patient is obese or has thick/rigid abdominal walls
Cardinal Movements of Labor (in order!)
Engagement < Descent < Flexion < Internal Rotation < Extension < Expulsion
Another term for “lateral flexion”
Asynclitism
Naegele’s Asynclitism
Anterior- Sagittal suture approaches promontory
Litzmann’s Asynclitism
Posterior - Sagittal suture approaches symphysis (Ear presentation)
Fetal Cephalic AP diameter conversion during Flexion
OF to SOB
Force acting posteriorly during Extension
Exerted by the uterus
Force acting anteriorly during Extension
Resistance by pelvic floor and symphysis
True or False: Ext. Rotation/Restitution returns fetal position to what it was when it started
True. If you start LOA, you end in LOA
