Foal Nursing Flashcards
How do we carry out a clinical exam on a recumbent foal?
Every 4-6hrs Thoracic auscultation, HR, RR MMs Palpation - joints, umbilicus Temperature - 37.5-39 degrees C
What other considerations should we have for nursing recumbent foals?
Sternal - support, bean bag Intra-nasal oxygen Keep clean, warm, dry IV catheter care Pressor support Urinary catheter care Hydration status
How do we feed a foal that is able to suck?
Mare is best
No mare - feed milk/milk replacer from bowl
RISK aspiration pneumonia if bottle feed
How do we feed a foal that is unable to suck?
Indwelling naso-gastric tube - X-ray to check position, feed by gravity
5% glucose spiked isotonic fluids short-term
Parenteral nutrition long-term
Monitor glucose, may need insulin SC or CRI
What blood tests should we carry out on a foal?
IgG SNAP ELISA PCV, TP Glucose White cells Creatinine Blood gas, electrolytes Lactate Culture
How do we make sure the foal has the right antibodies before foaling?
Vaccinations - influenza, EHV, rotavirus, tetanus
Last tetanus 4-6 weeks before foaling
Move mare to foaling environment 6 weeks before
What is an ideal foaling box setup?
5m x 5m Good ventilation Disinfected Warm, sheltered Bedding e.g. straw/shavings
On what timeframe do we expect the newborn foal to breathe, stand etc.?
1st breath within 30secs Attempt to stand - up by 30mins-1hr Drink colostrum by 1-3hrs Pass meconium Urinate
Why does respiratory arrest in equine neonates most commonly occur?
Premature placental separation Early severance or twisting of the umbilical cord Dystocia Airway obstruction by foetal membranes Failure to spontaneously breathe
What are some causes for cardio-pulmonary arrest in equine neonates not associated with birth?
Primary lung disease Sepsis Hypovolaemia Metabolic acidosis Hyperkalaemia Hypoglycaemia Hypothermia
When would be choose to stimulate a foal rather than begin resuscitation?
HR < 60bpm / irregular Slow/irregular respiration In lateral, some muscle tone On nasal mucosal stimulation, grimace THEN stimulate and provide intranasal oxygen
When would we attempt neonatal resuscitation?
HR/respiration undetectable
Muscle tone limp/absent
Unresponsive to nasal mucosal stimulation
How do we ventilate a foal during resuscitation?
Clear airway
Place naso-/ET tube (can do this whilst foal in birth canal)
Ambu-bag to tube if possible (if not, then mouth to tube / ambu-bag to mask / mouth to nose)
Short, infrequent breaths - 10 breaths/min
When do we attempt CPR in a foal?
Reassess 30 seconds after starting ventilation
If heart beat absent, less than 40bpm or less than 50bpm and not increasing
How do we do chest compressions in a foal?
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
What is failure of passive transfer (FPT)?
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
How can we test for failure of passive transfer?
SNAP ELISA
Easy, cheap, done in the stable
