Reproduction, Neonates & Geriatrics Flashcards
Common bacterial isolates in neonatal sepsis
Staphylococcus
Streptococcus
E. coli
Klebsiella
Enterobacter
Salmonella
Clostridium
Pharmacological considerations in neonates
- decreased renal excretion and hepatic metabolism
- Avoid oral administration
- Intestinal flora very sensitive to antimicrobials
- BBB more permeable
- Rely on HR to maintain CO so avoid cardio depressant drugs
- Opiods good as reversible
- Avoid hep saline
Antimicrobials preferred for neonates
b-lactams (12 hourly not 8 hourly)
Metronidazole for giardiasis and anaerobic infections
Normal MAP of 1 month old puppy or kitten
49mmHg
Most accurate method to monitor overhydration and underhydration
Body weight
(Can use PCV/TS)
- Skin turgor not effective measurement
Lactate is ______ in neonates
Higher
What is considered hypothermia for puppies and kittens
25.6-34.4
Fluid resuscitation in moderately dehydrated/hypovolaemic neonatal patients
30-40ml/kg bolus
CRI 80-100mL/kg/day
Preferred fluid for neonates and why
LRS - utilise lactate for metabolic fuel particularly if hypoglycaemic
Why does hypoglycaemia occur in neonates
Poor hepatic gluconeogenesis
Inadequate hepatic glycogen stores
Glucosuria
Inefficient counter-regulatory hormone release (clinical signs harder to identify)
Treatment of hypoglycaemia in neonates
1-3mL/kg 50% glucose (1:3 = 12.5%), repeat as required
CRI 2.5-10% through central line
Carnitine 200-300mg/kg PO q24 (max. glucose utilisation)
Autonomic NS doesn’t mature until what age in neonates?
8 weeks
Normal weight gain for neonates
Should double their weight in first 10 days
5-10% BW gain each day
- may be slower in formula fed neonates
- should weigh multiple times daily
- can lose 10% BW in first 24h after birth
Normal HR of neonates
Puppies 200
Kittens 250
Normal temperature of neonates
35.2-37.0 by week 4
True or false: puppies and kittens can have an innocent murmur <12 weeks of age
True`
Why do neonates have higher fluid requirements compared to adults?
Higher body water % compared to body fat
Increased metabolic rate
decreased renal concentrating
