In monotocus species, it is possible for
per vaginam delivery to occur with some slight postural abnormality T/F
F - poly dapat. (including sheep n goat w/ small mutiple fetuses)
correction of posture, presentation, and position abnormalities can be achieved via _____
essential prerequisite of the answer above?
intrauterine manipulation of the fetus
retropulsion of the fetus
the corrections above can be facilitated by?
caudal epidural anesthesia
In cases of prolonged dystocia, where fetal fluids have been lost, sterile water can replace the lost ____
allantoic fluid
nonsterile clean water can be used as substitution for lost fetal fluids. T/F
T
In cows and mare __ litters is administered using a ___ and funnel
14L, soft rubber/plastic/stomach tube
lubricant substitute (vaginal delibery) for ___ fluid
amniotic
3 examples of lubricant subs
lard
water-soluble cellulose-based obstetrical lubricant
soap flakes
obstetrician should consider 3 things: (FSE)
facilities are appropriate,
sufficient professional and
other help available,
equipment is adequate to carry out the treatment successfully
In severe forms of dystocia, more especially in mares, the veterinarian should always seek the the assistance of a professional colleague and consider
whether it might be appropriate to transport the animal to somewhere with hospital facilities, provided that the animal is in a fit state to travel T/F?
T
After a successful delivery, dam’s genital tract should always be examined for the presence of others; remember
that polytoccus species can have twins and rarely more. T/F?
F - mono sa poly
best instruments are the clean and gentle
_____ of the obstetrician
hands and arms
More complex equipment is rarely required, and the important consideration is to know when the use of such complicated instruments is indicated T/F
F - ocasionaly not rarely
a dedicated
____ is also important esp. to vets making routine visits on farms
caesarean operation kit
Many veterinarians find these easier to use than rope snares. Their main advantage is that they are heavier and do not move so readily when they are repositioned during intrauterine
or intravaginal manipulation
Moore’s obstetric chains (E) with handles (F)
- alt to snares
effective substitute for bull rings
snare introducer
These are useful when performing fetotomy to enable
traction to be applied to various fetal segments (OOHPB)
Obstetrical hooks include Krey–Schottler
double-jointed hooks (H),
Obermeyer’s anal hook (I),
Harms’s sharp (J) or blunt (L)
paired hooks on a fine (farrowing) chain (K),
Blanchard’s long, flexible cane hook (M).
instruments to use when performing TRACTION (BHV)
block and tackle,
HK calf puller
Vink calving jack
useful for performing subcutaneous fetotomy as well as during a caesarean operation in the cow when it is impossible to exteriorise the uterus to incise i
Unsworth’s fetotomy guarded knives
also used for subcutaneous fetotomy
spatula
Persson’s chain-saw is now replaced with
polyfilamentous fetotomy wire
which are a cheaper alternative of protecting the dam’s genital tract than the Thygesen’s model
Gättli’s spiral tube
pushing the fetus cranially
from the vagina (and the bony pelvic canal)
towards the uterus
retropulsion
2 ways retropulsion can be performed
- pressure with the hand on the presenting bulk of the fetus; in some cases, it is convenient for an assistant to repel the fetus while the obstetrician manipulates it
- use of crutch
