incompatible with life

86
Q

why is incomplete ossification of the cuboidal bones such a concern in foals?

bone will crush leading to joint abnormalities for life

87
Q

keep foal recumbent for as long as possible to allow bones to mature and ossify

88
Q

surgery

92
Q

why should you never lift foals by their abdomen?

Q

what is the role of ICU nurse for foals?

A

patient care
foal and mares needs
staying organised
keeping unit clean and stocked
communication of patients
wearing PPE

96
Q

list general nursing care of foals in ICU

A

maintain sternal recumbency to prevent atelectasis
assist standing every 2 hours if well enough
turn 2 hourly to prevent pressure sores
weigh daily
close examination

97
Q

what is monitored in NICU exams

A

complete physical exam
demeanour
nose to tail checks
manage treatments
nutrition
urine and fecal output
at least 4 hourly checks, more if sicker

98
Q

list CV system checks in NICU foals

A

MMs - indicate systemic health, multiple locations (buccal mucosa, conjunctiva, ear pinnae), should be pink, moist
CRT - less than 2
HR - 80-100, strong pulses, warm extremities
CO - relies on stable HR
may have murmurs until day 4 as fetal vessels closing

99
Q

why does CO rely on HR in foals?

A

cant adjust stroke volume due to immature sympathetic nervous system

100
Q

what is the result of poor compensation of heart rate in foals?

A

poor BP and oxygenation

101
Q

list respiratory system checks in NICU foals

A

RR - 30-40
regular rhythm
louder bronchial sounds than adults
no wheezes
dullness
crackles
respiratory effort

blood gas for oxygenation

102
Q

list what may be seen in eye checks for unwell NICU foals

indicate systemic state
dehydration seen with sunken eyes and entropion
sepsis if injected MM, hypopyon (fibrin and pus accumulation), uveitis
trauma seen with injected conjunctiva and swollen eyelids

103
Q

why are corneal ulcers common in foals?

A

have reduced corneal sensitivity

104
Q

what should be assessed in NICU foals MSK?

A

lameness
septic synovitis/osteomyelitis
check all joints
reduce weight bearing if premature or dysmature
