Periparturient dz intro + postpartum hemorrhage Flashcards
uterine inertia
and followed by delay in uterine involution.
dystocia
3 results of dystocia
retention of the fetal membranes and
puerperal metritis / prolapse of the uterus and puerperal infexn
predisposes genital tract to infexn, anaerobic bacteria
Obstetric trauma
serious complication of the third stage
of labour, but it is more likely to happen after
normal birth than after dystocia
prolapse of the uterus
lead to fatal haemorrhage or infection, or to
disability due to fractures, dislocations or paralysis.
Traumatic lesions of
the soft tissues of the genital tract or bony pelvis
Other complications of parturition
displacement, hernia and rupture of the pelvic or
abdominal organs
Parturition and the puerperium may also be complicated by metabolic disease
hypocalcaemia and
ketonaemia, and by displacement of the abomasu
difficult foaling may be followed by
l
laminitis or tetanus,
in horses, puerperal
animals may incur embolic pneumonia, toxaemia,
septicaemia and pyaemia t/f
f - all spceies daoat
possible later sequelae
Endocarditis, unthriftiness and sterility
the most
frequent basic cause of parturient and postparturient disease is
delay in giving obstetric aid
to dystocia cases.
Unskilled and unsympathetic
interferenc
Bleeding from the maternal side of the placenta
postpartum hemorrhage
breakdown of the marginal
haematoma is accompanied by what color of discharge
green or brown
premature
dehiscence occurs when the afterbirth is removed
during an elective caesarean operation, severe and
even fatal haemorrhage may follow t/f
t
horse, swine, ruminants placenta
epitheliochorial and
synepithelial chorial placentae <– hemorrhage when excessive force is appplied in cotylednary type of placenta is used
usual cause of serious hemorrhage
laceration of a uterine blood vessel by a fetal
appendage, obstetric instrument or hand of the
obstetrician
there is a
profuse haemorrhage from the vulva, the most
likely source is the broken ends of the vessels of ____
umbilical cord which have eneded in the vagina
fetal side of the placenta
allantchorion
profuse hemorrhage in vulva: This is likely to occur in uterine inertia
where, owing to poor uterine contractions, much
of the blood from the fetal side of the placenta
(allantochorion) is not expelled into the fetus
during 1st-stage labou t.f
f - third stage
Such
haemorrhage from the allantochorion does not
affect the dam and offspring. t/f
f- young animal is thereby
deprived of a natural blood transfusion and this
could be the cause of cerebral anoxia in newborn
foals.
profuse haemorrhage is
occurring from a uterine laceration, prompt contraction of the uterus should be promoted by
means of an injection of ____
oxytocin
Haemorrhage associated with uterine
___ is attended to when the uterine tear is
repaired.
Ligation is usually not
practicable but____ may be applied
and left on for 24 hours
Rupture
artery forceps
Where the vessel cannot
be secured, an intravaginal pressure pack can be
improvised with a large ___, or by the
insertion of a large roll of ___
clean towel
acotton wool
General
symptoms of severe haemorrhage and shock can
be counteracted by _____ and how many liters?
from a neighbouring animal.
blood transfusion
4-5L
Fatal haemorrhage from vessels in the ____ has been seen in the mare and cow
broad ligament
ovarian, uterine or external iliac
arteries in foaling (eight) or pregnant
Fatal haemorrhage from vessels in the ____ has been seen in the mare and cow
broad ligament
The ruptures were associated with
_____ or degenerative changes in the arteries
and it was presumed that these lesions were predisposed to by __ and that the actual ruptures
were caused by stretching during pregnancy or
pressure during parturition
aneurysm
age
Where such haemorrhage is suspected, the only hope of saving the
animal would be prompt ___ and _____
of the torn vessel
laparotomy and ligation
