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)

A

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

A

present from birth regardless of cause, born with the condition, can be genetic or environmental (trauma in womb, drugs, nutrition)

38
Q

genetic abnormalities

A

cause based in DNA

39
Q

neonatal physical exam: body hair

A

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
Q

what do the different neonatal ventral abdomen skin colors mean?

A

dark pink= normal
blue= cyanosis
dark red= sepsis

41
Q

1st week neonatal developmental landmarks

A

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
Q

normal body temperature of a neonate

A

94.7-100.1 F

43
Q

2nd week neonatal developmental landmarks

A

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
Q

sexing puppies and kittens

A

puppies: testicles descend into scrotum by 6-8 weeks
kittens: palpable at birth, not visible until 6-8 weeks

45
Q

routine puppy/kitten maintenance

A

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
Q

head abnormalities to look for during neonatal physical exam

A

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
Q

primary cleft palate

A

slit between nose and lip
good survival rate
hard to nurse until surgery can be done

48
Q

secondary cleft palate

A

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
Q

chest abnormalities to look for during neonatal physical exam

A

pectus excavatum: constriction of thoracic cavity, common in Maine Coons, can be fatal

50
Q

puppy/kitten body condition

A

puppies: pudgie but symmetrical (asymmetrical could mean distended abdomen from worms or ascites)
kittens: lean

51
Q

abdomen and urachus abnormalities to look for during neonatal physical exam

A

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
Q

how long do puppies/kittens need to be stimulated to urinate and defecate for?

A

until 3 weeks

53
Q

what to look for with the tail during neonatal physical exam

A

muscle tone, length, kinks, curls

54
Q

neonatal urine and stool

A

urine should be clear-pale yellow
dark stool= meconium (1st stool of a neonate)
yellow stool: milk feces
stool should be firm/formed

55
Q

blood sampling a neonate

A

obtain from jugular vein
can only take 5% of circulating blood volume

56
Q

urine sampling a neonate

A

can obtain by stimulating, manually expressing, or cystocentesis
cystocentesis: only do ultrasound guided and only a skilled tech should do, use 25G needle

57
Q

neonatal illnesses that need immediate attention

A

hypothermia, dehydration, hypoglycemia, neonatal isoerythrolysis, malnutrition

58
Q

hypothermia in neonates

A

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
Q

ages and temps for diagnosing hypothermia

A

at birth: <94 F
1-3 days: <96 F
1 week: <99 F

60
Q

what is important to know about resuscitation and hypothermia in neonates

A

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
Q

how to treat hypothermia

A

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
Q

dehydration in neonates

A

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
Q

hypoglycemia in neonates

A

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
Q

neonatal isoerythrolysis: kittens

A

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
Q

malnutrition in neonates

A

CS: constant crying, extreme inactivity, failure to gain weight

66
Q

milk replacers for neonate feeding

A

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
Q

neonate feeding

A

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
Q

amount per neonatal feeding

A

puppies: 10-20 mL
kittens: 4-5 mL

69
Q

neonatal feeding energy requirements

A

~20-26 kcal/100g
