Q

How do we ventilate a foal during resuscitation?

Q

When do we attempt CPR in a foal?

A

Reassess 30 seconds after starting ventilation

If heart beat absent, less than 40bpm or less than 50bpm and not increasing

Q

How do we do chest compressions in a foal?

A

Knee parallel to spine
Hands on top of each other
Caudal to triceps at highest point of thorax
Shoulders above hands so can use bodyweight
Optimal chest compression - push hard!
Ideally 1 person to compress and 1 to ventilate - no pauses
Compression to ventilation ratio 15:1
Compressions 100-120 per minute

Q

What is failure of passive transfer (FPT)?

A

All antibodies received from colostrum, should suck within 1-2hrs
Gut ‘open’ for 24hrs, in that time allows in not just antibodies but bacteria
Partial FPT 400-800mg/dl
Total FPT < 400mg/dl
Normal > 800mg/dl
FPT massive risk for sepsis

Q

How do we treat failure of passive transfer?

A
Hyperimmune plasma transfusion
Defrost slowly
Blood giving set (filter)
Start slow (risk transfusion reaction)
1L over about 1hr
Re-test after each bag
19
Q

What are the clinical signs of sepsis?

A

Pyrexia, depression, recumbency, injected MMs

20
Q

How can we test for sepsis?

A
Blood culture - white cell count, SAA, SNAP test, creatinine
USG
Glucose
Lactate
Culture from umbilicus?
Joint sample for cytology and culture?
21
Q

How can we treat sepsis?

A
Broad spectrum antibiotics
Plasma - even if no failure of passive transfer?
Joint lavage
Remove umbilicus?
Intensive care - nursing recumbent foal
22
Q

Describe seizures in foals.

A
Generalised convulsions / subtle signs
Many causes
Correct primary cause if possible
Maintain airway, admin oxygen

Q

What is dummy foal syndrome?

A

AKA hypoxic ischaemic encephalopathy / perinatal asphyxia syndrome
Hypoxia at birth/in vivo

Parenteral nutrition/slow enteral feeding
Squeeze?

26
Q

Define prematurity, dysmaturity and postmaturity.

Prematurity < 320 days usually require vet attention, 280 days unlikely to survive
Dysmaturity = look premature despite normal or often longer gestation
Postmaturity = long gestation, normal size but emaciated
