Obstetrical Maneuvers Flashcards
most common obstetrical maneuver
mutation (correction) and forced extraction (may be after mutation)
recommended obstetrical maneuver for small animals
CS
change of presentation, position, posture to bring fetus to a normal presentation, position, posture
mutation/correction
specific manipulations
- repulsion or retropulsion - done for small pieces
- rotation - in cases where you have problems w/ position
- version - presentation problems
- extension and flexion - posture problems
requirements prior to performing mutation
- complete dilatation of cervix
- movement of fetus in uterus and pelvis
- rupture of fetal envelopes
- adequate lubrication
- caudal epidural
w/c is more prefered: mineral oil or vegetable oil
vegetable oil
it pumps in lubricants into uterus
stomach pump
used for coat lining of birth canal
vaseline
returning of fetus back to uterus
retropulsion
useful instrument for retropulsion
- Kuhn’s crutch - U-shaped
- Reindi’s repeller
- Gunther repeller
T/F: retropulsion should be done when the uterus is relaxed and the abdomen is not contracting
T
_______________ - turning the fetus on its long axis to correct the position using hands or ___________________
- rotation (aims for dorsopubic or dorsoileal)
- Cammerer’s detorsion fork
effecting change in fetal presentation
version
T/F: it is difficult if you want to convert from posterior longitudinal to anterior longitudinal presentation
T
T/F: perform version if the fetus is in transverse position
T
T/F: as long as the limbs are extended, forced extraction can be done
T
T/F: transverse presentation can be modified to a longitudinal presentation
T
type of version where you move the head of the fetus towards the pelvic inlet
anterior or cephalic version
type of version where posterior parts of fetus are moved towards the pelvic inlet
posterior or pelvic version
extension and flexion involves:
- repulsion of proximal extremity of limb
- lateral rotation of middle portion carpus, tarsus, neck
- traction on distal extremities
done in forelimbs
conversion
T/F: carpal flexion should be converted first into elbow flexion
F - baliktad
T/F: shoulder flexion should be converted first into elbow flexion then carpal/shoulder flexion then carpal flexion again
T
T/F: hip flexion should be converted first to hock flexion
