Obstetrical Maneuvers pt. 1 Flashcards
4 classifications of obstet maneu
Mutation (or correction) - COMMON
Forced extraction (may be after mutation) - COMMON
Fetotomy
CS
- For small animals - recommended for small animals
Definition: change of presentation, position or posture to bring the fetus to a normal presentation, position and posture
Ex. dorsotransverse fetus → maneuver → normal anterior longitudinal position
mutation/correction
4 Specific manipulations
Repulsion or retropulsion
-Have space to work in
Rotation
Version
Extension and flexion
Requirements prior to performing mutation:
Complete ____of the cervix;
movement of fetus in ___ and ____
rupture of fetal envelopes and adequate lubrication;
dilation
uterus and pelvis
instruments of mutation/correction
- Obstetrical chains
Oblong ends “like choke chains” - thread one into the other - Obstetrical handles
- Stomach pump
-Pump in lubricants into the uterus/ birth canal - Stomach tube
5.Bucket of clean water
-For washing
- Soap
7.Lubricant/s
-Vegetable oil - cheaper, easy to find
-Water-based obstetrical lubricants
8.Vaseline
-Coat lining of birth canal
obstetric chains: longer ones go to the shoulder, shorter ones go around pastern of the animal t/f
t
Returning fetus back to the uterus
Pushing fetus _____ in uterus to obtain adequate space for correction of fetal part in an abnormal presentation, position and posture
may be done only with instruments t/f
Do this when the uterus contracts, when the abdomen is not contracting. t/f
retropulsion
forward
f - can be done with hands
f - uterus RELAXES
instruments for retropulsion krg
Kuhn’s crutch
-U-shape pushed against shoulder or any part u want to push back to gain leverage
Reindi’s repeller
Gunther’s repeller
in handling dystocia in mare - put in ____ ataching the hindlimb into a ___
can you put lubricant? yes or no
This technique will help you in the mutation of fetal malpositions and even dystocia due to presentation problems not only in the mare but also in cattle and buffaloes. t/f
lateral recumbency
pulley
yes
t
Positional problems
Turning the fetus on its’ long axis to correct the position
Aims for Dorsopubic/dorsoileal presentation - nakabaliktad back of fetus is closee to pubis or ileum → goal is to rotate back to _____ position
instrument used
rotation
dorsosacral
cammerer detorsion fork
Problems with presentation
Effecting change in fetal presentation.
Difficult if you want ot convert from posterior to anterior longi presentation
If you have fetus in transverse position
version
ventral presentation can be modified to a longitudinal presentation t/f
Usually limited to ___ (angle) and can be done by repelling one extremity of the fetus and exerting traction on the other.
f - transverse to longi
90
Push hindlimb pull forelimb
Push - ___
Pulling – _____
First pass around shoulder
Attached a rope → assistant pull when ready to push → anterior longitudinal presentation
procedure for dorso trasnvers
repeller or hand
obstetric chains
type of dorso transverse
moving the head of the fetus towards the pelvic inlet
More difficult if neck is also bent
posterior parts of the fetus are moved towards the pelvic inlet
Hindlimbs come out first
anterior or cephalic version
posterioir or pelvic version
position - solution
posture - solution
presentation - soln
rotation
extension and flexion
