Flashcards in canine obstretics Deck (18):
1-2 weeks before parturition/predicting parturition
clear/tan vulvular discharge, nesting behaviour. anorexiz, panting, mammary development. temp drop 1 degree day before due to metabolism change. p4 drops to less than 2, and prolactin increases
radiographs show progressive ossification. ultrasound shows organs, GI, peristalsis.
preparation, fetal expulsion, placental passage
at birth, stimulate to breath by rubbing and drying it. ensure colostrum for passive transfer. if fail use maternal serum. dystocia common in small, squatty dogs. bulldogs, terriers.
stages of parturition
frank vulvular hemorrhage. green vulvular discharge before pups. uterine inertia- inability for uterus muscles to contract, even with oxytocin. primary-hypocalcemia-calcium glutonate? secondary-obstructive dystocia-surgery. inadequate birth canal size, strictures, vaginal septae. fetal oversize. uterine torsion or rupture. dont give oxytocin with obstruction. discontinue after 3 doses.
assist vaginal delivery
dont pull limbs. correct positioning. clean and lubricated.
c section anesthesia
ketamine, methoxyflurane, xylazine, acepromazine. poor fetal outcome. pre-oxygenate the bitch preoxygenates teh feti. if puppy is yellow, brown, it is meconium. aspiration pneumonia. get all pups out. milk uterus. dont tear placenta unless easy. close uterus and give oxytocin to expel, usually. 1-2 days before end of gestation, when p4 levels drop. fetal hr must be over 180bpm
end of gestation for fetal maturation. prednisolone, dexmethasone
no swinging the puppy. ensure puppy is dry and warm. vigorous rubbing to get breathing.
airway, breathing, circulation, drugs (Dextros, doxapram, ep), dry and warm
cleft palate, limbs, toes, functional anus, umbilical hernia, gender
3 months post partum. lochia (discharge) is common, no order. min 4 months between estrus cycles.
lack of milk production or milk letdown. nutrition-- needs 2.5-4x maitenance
postpartum depressed bitch
mastitis, check mammary glands. swollen, hot, painful. ecoli, etc. acute puerperal metritis is an emergency- agressive treatment. OHE. check lochia color and quality
eclampsia, puerperal tetany. smaller dogs. cns signs and possible death. 1-4 weeks post partum.
sub involution of placental sites
fetal tissues remain attached to uterus. can cause some irritation/bleeding. prolonged bloody vulvular discharge. may result in anemia. cytology can show retained trophoblastic cells.
