Q

how can you tell when a female dog is in estrus?

A

measure progesterone (P4) and luteinizing hormone (LH) spikes to determine time through bloodwork, vaginal cytology, and bitch behavior (will stand for a male to mount and breed, more frequent urination, nesting behaviors, licking vulva, tail between legs during proestrus and will be held off to one side during estrus)

Q

feline estrus cycle

A

induced ovulators
daylight dependent
estrus behaviors: increased vocalizing, rolling, lordosis, treading in place, may have anorexia or spraying
breeding is best at day 3 of estrus
copulation (sex): LH released within minutes, less than 50% ovulate with single mating
3 possible outcomes: pregnant (CL), nonpregnancy (CL), no ovulation (no CL)

feline placenta type
zonary endotheliochorial
26
when would a kitten be considered premature?
under 60 days of gestation not usually viable
27
what are the different tests and times for diagnosing kittens?
signs: larger teats, weight gain ultrasound: heartbeat at 16 days palpation: 18 days radiograph: after day 40 (most useful at day 60) *after days 32-35 the kittens are no longer individually discernible
28
how long does feline partuirition take?
takes a couple hours - over a day
29
what happens during stage 1 of queening?
uterine contractions, no abdominal contractions nesting and decreased activity increased fetal movements, lactational secretion relaxation around perineal area ends with chorioallantoic membrane rupture
30
what happens during stage 2 of queening?
fetuses delivered
31
what happens during stage 3 of queening?
placenta passed uterus returns to normal
32
average canine litter sizes
avg: 4-10 puppies smaller breeds: 1-4 puppies larger breeds: 8-12 puppies
33
average feline litter size
1-5 kittens
34
birthing red flags
strong continual contractions for 30 minutes without progress weak, infrequent contractions for 2 hours without progress prolonged interval between puppies malpositioning/ large size of fetuses prolonged gestation period (70-72 days) extreme pain/exhaustion of bitch/queen
35
dystocia
difficult birth
36
what are some materials used for a neonatal physical exam?
pediatric stethoscope (2 cm bell) digital thermometer (measures as low as 85 F) warm clean surface for examination (can't regulate body temp for first 2 weeks) freshly laundered towels or blankets (extremely susceptible to disease and might not have even drank colostrum yet)
37
congenital abnormalities
present from birth regardless of cause, born with the condition, can be genetic or environmental (trauma in womb, drugs, nutrition)
38
genetic abnormalities
cause based in DNA
39
neonatal physical exam: body hair
should cover most of body except ventral abdomen lack of hair or sparse hair is caused by a genetic abnormality or premature birth discharge from orifices is normal
40
what do the different neonatal ventral abdomen skin colors mean?
dark pink= normal blue= cyanosis dark red= sepsis
41
1st week neonatal developmental landmarks
sleep 80% of time, nurse every 2-4 hours motor skills: lift head by 3 days, crawl by 1 week, suckle, vocalize distress, purr umbilical cord dries and falls off by day 3 only respond to odor, pain, and touch stimuli
42
normal body temperature of a neonate
94.7-100.1 F
43
2nd week neonatal developmental landmarks
body temperatures rise toward adult levels double birth weight (kittens: 10-15 g/day, puppies: 5-10% of weight/day) eyes open at 7-12 days (appear cloudy) ear canals open at 14-16 days
44
sexing puppies and kittens
puppies: testicles descend into scrotum by 6-8 weeks kittens: palpable at birth, not visible until 6-8 weeks
45
routine puppy/kitten maintenance
healthy mothers with good instincts will take care of healthy neonates without help (carefully monitor mother/neonate interactions for c-sections) start deworming at 2 weeks (3-part deworming at 2-week intervals) take weight BID for 3-4 weeks provide care kits
46
head abnormalities to look for during neonatal physical exam
open fontanels (brain sutures don't close, common in chihuahuas, causes coordination issues and seizures), cleft palate, neonatal ophthalmia (eye infection), abnormal nares (stenotic nares)
47
primary cleft palate
slit between nose and lip good survival rate hard to nurse until surgery can be done
48
secondary cleft palate
hard palate doesn't fuse fully leaving a hole in the top of the mouth which causes milk to come out of the nose
49
chest abnormalities to look for during neonatal physical exam
pectus excavatum: constriction of thoracic cavity, common in Maine Coons, can be fatal
50
puppy/kitten body condition
puppies: pudgie but symmetrical (asymmetrical could mean distended abdomen from worms or ascites) kittens: lean
51
abdomen and urachus abnormalities to look for during neonatal physical exam
never bloated, ensure no patent urachus patent urachus: urethra connects with umbilical cord in the womb but should close when born, doesn't close in patent urachus
52
how long do puppies/kittens need to be stimulated to urinate and defecate for?
until 3 weeks
53
what to look for with the tail during neonatal physical exam
muscle tone, length, kinks, curls
54
neonatal urine and stool
urine should be clear-pale yellow dark stool= meconium (1st stool of a neonate) yellow stool: milk feces stool should be firm/formed
55
blood sampling a neonate
obtain from jugular vein can only take 5% of circulating blood volume
56
urine sampling a neonate
can obtain by stimulating, manually expressing, or cystocentesis cystocentesis: only do ultrasound guided and only a skilled tech should do, use 25G needle
57
neonatal illnesses that need immediate attention
hypothermia, dehydration, hypoglycemia, neonatal isoerythrolysis, malnutrition
58
hypothermia in neonates
take body temp to diagnose (only take rectally) clinical signs: - <94 F: suckling diminishes, GIT hypomotile (ileus) - <88 F: restlessness, continuous crying, red mm, skin cool to touch, suckling stops - 78-85 F: lethargic, uncoordinated, still responsive, moisture around corner of lips, decreased HR, decreased RR, no gut sounds - <70 F: appear dead, hypoxia
59
ages and temps for diagnosing hypothermia
at birth: <94 F 1-3 days: <96 F 1 week: <99 F
60
what is important to know about resuscitation and hypothermia in neonates
if too cold they can appear dead so continue CPR until body temp is in normal range if in normal range and still unresponsive then the neonate is considered dead
61
how to treat hypothermia
slow rewarming: about 2 F/hour (>4 F/hour will cause delayed organ failure/death) monitor for thermal burns warm IV fluids (no more than 2 F above current body temp) can tube feed warmed LRS with 50% dextrose (only with audible gut sounds) no food!!
62
dehydration in neonates
any disease process or imbalance of fluids can quickly lead to dehydration fluid requirements are high in neonates less able to conserve fluids all fluids need to be warmed to 98-99 F routes: oral, IV, IO SQ can be used to prevent dehydration only 1 puncture per bone for IO
63
hypoglycemia in neonates
dog: <30 mg/dL cat: <50 mg/dL neonate born with few glycogen stores and there is poor gluconeogenesis in liver so risk is great healthy neonate can maintain normal glucose levels for up to 24 hours without nursing hypoglycemia most common cause of seizures
64
neonatal isoerythrolysis: kittens
if kitten has type A blood and queen is type B, colostral antibodies will bind and lyse red blood cells in the kitten causes severe anemia, nephropathy, and organ failure CS: jaundice (2 days old), tail tip necrosis (10-14 days), death purebreds usually have type B and domestic cats usually have type A
65
malnutrition in neonates
CS: constant crying, extreme inactivity, failure to gain weight
66
milk replacers for neonate feeding
warmed to 95-100 F use commercially available milk replacers never use cow's milk or other milks never use milk replacer if neonate is hypothermic
67
neonate feeding
should be fed every 2-4 hours (early intake is limited by stomach volume) can tube feed for neonates that won't nurse, have a poor suckle, or are not gaining weight feed in sternal recumbency with head at relaxed position hold bottle/syringe horizontal to minimize air ingested burp and stimulate to eliminate agter feeding never hold on back like a baby
68
amount per neonatal feeding
puppies: 10-20 mL kittens: 4-5 mL
69
neonatal feeding energy requirements
~20-26 kcal/100g
