Q

treatment - gastric foreign body

A

induce vomiting - apomorphine for dogs, xylazine for cats - only if quite certain can be expelled without harm
correction of acid base
withold food - 12 hours
radiographs immediately before surgery or endoscopy - localise foreign body
perioperative antibiotics
gastrotomy - to inspect whole GIT
don’t pull on linear foreign body unless comes loose easily
endoscopy - to remove foreign body, care of sharp edges
antiemetics if vomiting continues

prognosis good so long as stomach not perforated and foreign body removed

Q

GDV pathophysiology

A

enlargment from gastric outflow obstruction - can’t vomit, eructate or empty pylorus to intestine
enlarged with gas/fluid
stomach rotates, usually clockwise ( from surgeons perspective)
spleen displaced to right ventral abdomen
caudal vena cava and portal veins obstructed - reduced venous return and cardiac output, myocardial ischemia, obstructive shock and inadequate tissue perfusion
affects multiple organs

arryhtmias common

Q

risk factors GDV

A

exercise after large meals or a lot of water
soy or cereal based dry foods
irish setters fed single feed type
large meals (regardless of number of meals daily)
feeds that are high oil or fat content
anatomic predisposition
gastric ileus
trauma
primary gastric motility disorders
vomiting
stress
male sex
increasing age
low BCS
rapid eating
raised feeding bowl - may promote aerophagia
dry kibble anxious dogs
spending 5 or more hours with owner
egg supplements
equal time in and outdoors
splenectomy (maybe)

military dogs more commonly develop GDV in November, December, Janurary - don’t know why

adding table food to large or giant breed dogs may decrease GDV incidence

Q

fluid therapy - acute haemorrhage - horse

A

assess if controlled or not
need coagulation factor replacement

uncontrolled -
persistant hypotension - dangerous
aim to support circulating blood to minimum volume needed for tissue perfusion until controlled
crystalloids indicated if donor blood not immediately available and the case is an emergency
blood products preferred

controlled -
if definitive hemotasis - expand volume with crystalloids, hypotonic saline, or blood
if unstable controlled - replace minimum of estimated blood lost, can give initial bolus
blood products preferred as not diluting RBCs

crystalloids and synthetic colloids can dilute RBSs and clotting factors - increase BP so destabilising clot and increasing bleeding, may also cause hypocoagulation

testing - pyrexia of unknown origin - equine

A

clinical exam
hemo and biochem - inflammation may not show in bloods if erly stages, SAA and fibrinogen useful to guide whether acute or chronic, low WBC and left shift in severe infection
peritoneal fluid - peritonitis, increased WBC and TP indicate intra-abdominal infalmmation, cytology for insight into cause, culture if WBC increased
rectal palpation
US thorax and abdomen
nasopharyngeal swab - combined PCR influenza, strangle and EHV 1 and 4 - negative result doesn’t rule out

bacterial pneumonia - US lungs - pleural effusion and lung parenchyma consolidation, trachel wash and BAL also useful (but more invasive)

trial treatment - pyrexia of unkwon origin - small animal

A

only for animals confortable to send home - alert, eating and drinking, not clinically dehydrated

focus on most common causes (cats - FIP, cat flu, infection, dogs - kennel cough, steroid responsive meningitis)

NSAIDs - correct dehydration first
fluids
antibiotics - esp in cats with suspected cat bite that can’t be found - amoxyclav, in dogs most causes are viral
steroids - if signs suggest steroid responsive meningitis, confirm not bacterial first because steroids will make that worse

Q

challenges for mother - c-section anaesthesia

A

physiological anemia - increase in blood volume but no increase in RBCs
increased oxygen demand
decreased functional residual capacity of lungs (pressure on diaphragm) and increased alveolar ventilation (panting) - rapid reuptake and offloading of anaesthetic gases
enlarged and full abdomen - can’t breathe well on their backs
poor venous return - compressed vena cava
increased prgesterone and increased blood brain barrier permeability - quicker sedation
delayed gastric emptying, decreased oesophageal sphincter tone, lower gastric pH - greater regurgitation risk
electrolyte disturbances
exhaustion and pain

Q

pre med - c-section anaesthesia

A

reduces stress - improves uterine blood flow
reduces induction and maintenance agents needed - reduced negative cv effects and foetal drug exposure
care with locals - can cross placenta and ionise so can’t cross back

full mu agonists - sedation and anaesthesia, minimum cv effects, maternal bradycardia potential but treatable, foetal hr not affected because not under autonomic control

short acting fentanyl an option if want to be quick

ACP - avoided generally - prolonged sedation and hypothermia in mother - no increased mortality so can use if needed

alpha-2s - xylazine associated with increased mortality

maintenance - c-section anaesthesia

A

iso or sevo in oxygen

IPPV

avoid nitrous oxide

only use neuromuscular blocking agents if familiar with use - need IPPV because won’t be able to breathe

epidural - good if familiar, if not increased time, decreased epidural space because of engorged sinuses, lidocaine

extradural opioids - good, minimal systemic effects

Q

analgesia - c-section anaesthesia

A

pain –> sympathetic stimulation –> sudden reduction in uterina blood flow –> hypoxia –> puppy mortality
welfare
inadequate analgesia associated with decreased milk production

NSAIDS - useful in dam, often given after puppies removed, negligible transfer in milk
opioids - excellent analgesia, can accumulate but can be antagonised through IV injection to umbilical vein (naloxone or butorphanol to antagonise)

pleural effusion

pulmonary oedema - left sided
ascites, peripheral oedema - usually right sided

123
Q

A

tachypnoea/dyspnoea
reduced exercise tolerance
reduced appetite
lethargy
weight loss
abdominal distension

124
Q

CHF tests

A

Essential -
TFAST/POCUS - fluid, left atrium size

bonus -
BP
biochem
xray - if stable

125
Q

CHF sedation

A

methadone or butorphanol - if thromboembolism butorphanol not enough

126
Q

Furosemide CHF

A

Either every 4 hours, based on CRI or based on resp rate
monitor mentation - if stressed may artificially rase resp rate
care not to dose too much - kidney injury

diuretic

127
Q

CHF thoracocentesis

A

required to fix significant pleural effusion
day 1 skill
can US guide
quickly reduces resp effort
if inspiratory dyspnoea - can usually assume pleural effusion without needing US

128
Q

CHF pimobendan

A

management of chronic heart disease
utility in emergencies less clear
improves cardiac output and systolic function - not usually the main issue in an emergency
care if suspected obstruction - cats, or dogs with aortic stenosis

expensive

129
Q

CHF radiographs

A

gold standard confirmation
only use once stable to sedate and restrain
after thoracic US, thoracocentesis and diuretics

assessment for concurrent disease

130
Q

pericardial effusion signs

A

muffled heart sounds - main thing
ascites - right sided heart failure
weak pulses
paradoxical pulses
collapse

lethargy
weakness
exercise intolerance

131
Q

pericardial effusion diagnosis

A

echo/TFAST - check for effusion and right atrium collapse (tamponade)
tamponade - main sign need pericardiocentesis
check for masses on US - usually hemangiosarcoma or heart base masses
radiographs - US quicker, do first

132
Q

pericardial effusion - treatment

A

pericardiocentesis - only treatment if tamponade
IV fluid boluses - support cardiac filling to stabilise

DO NOT GIVE FUROSEMIDE - makes mild effusion severe, can be fatal

133
Q

Aortic thromboembolism presentation

A

complication associated with severe heart disease - blood clots thrown off from left atrium

cats
usually caudal aorta - hindlimb paresis
less commonly forelimb, sometimes just one forelimb
pain - vocalising - distressing
absent femoral pulses
cold paws
cyanosis

134
Q

aortic thromboembolism management

A

euthanasia should be considered
if after 72 hours unlikely to further deteriorate
prognosis poor - esp if hypothermia, low HR, multiple limbs affected, absent motor function
long recovery, usually permanent deficits, risk of recurrence

pain relief - methadone, butorphanol not enough, NSAIDs risk kidney injury
furosemide if concurretn heart disease
clopridogrel - anticoagulent - possibly better than aspiring for reducing recurrence
aspirin - anticoagulent - can be used with clopridogrel
rivaroxaban - anticoagulent - newer, expensive

clot breaking drugs
tissue plasminogen activator - risk of reperfusion issue from toxins released from clot
low molecular weight heparin - slower effect - owners can inject at home

135
Q

diagnostic ECG - lead positions

A

red - right fore
yellow - left fore
green - (left) fore

136
Q

diagnostic ECG - considerations

A

electrical interference from other devices
is it tachy or brady
is the HR appropriate for the situation - emergency, stress, pain
regular ror irregular
pulses - weak in shock, same time as heart beats, pulse per beat
P for every QRS?
QRS for every P?
normal QRS? - tall and narrow normal, wide and bizarre not

137
Q

ventricular tachycardia ECG

A

short R-R - premature ventricular complex
no P
wide QRS
4 or more VPCs at fast rate - >160-180bpm

if slow rate - not emergency
emergency - will be showing signs - eg collapsed

138
Q

causes ventricular tachycardia

A

cardiac disease - basically always primary cardiac in cats, mostly in dogs, but sometimes none cardiac

neoplasia - splenic, hepatic
GDV
SIRS/sepsis
toxins
anemia
trauma

139
Q

ventricular tachycardia treatment

A

lidocaine - bolus then CRI - care with cats, can get neurotoxicity easily, always be a bit careful anyway as any animal can get neuro signs
majority will respond to some degree to lidocaine

continuous ECG monitoring
check electrolytes - hypokalemia reduces lidocaine efficacy - could be addisons or blocked cat
sotalol - coming off lidocaine, longer term oral meds
refractory cases - referral - amiodarone or electrical cardioversion

140
Q

emergency bradycardia

A

3rd degree atrial ventricular block

or high grade 2nd degree

141
Q

3rd degree AV block ECG

A

no communication between atria and ventricles

P waves but QRS not associated
QRS wide and bizarre, not premature

142
Q

sick sinus syndrome presentation

A

old dogs
westies and schnauzers
not an emergency
pauses in rhythm on ECG

143
Q

persistent atrial standstill presentation

A

rare
usually springer spaniels

looks similar on ECG to 3rd degree block but no P waves

144
Q

3rd degree block management

A

check potassium - could be addisons or blocked cat
treat underlying disease and electrolytes
chronotropics - terbutaline - sick sinus might respond, otherwise usually doesn’t

referral - pacemaker

if escape beat rate 50-60bpm - bad - but probably not middle of the night surgery emergency
if rate 30-40 - more urgent, usually present collapsed - still probably not the best idea to do OOH pacemaker

145
Q

need anaesthesia, but have to leave machine outside because metal
longer than CT and more expensive

planes - sagittal, dorsal, transverse

IV paramagnetic agent - gadolinium

indications -
gold standard - shows brain, spinal cord and peripheral nerves

CT+MRI - best for most detail for surgical planning

153
Q

equine - acute MSK emergency - initial assessment and first aid

A

ideally don’t move but may need to - owner might have anyway, lighting, floor
give owner instructions on haemorrhage control - pressure, multi layer bandage, esp if arterial bleed
remove foreign object if sticking out a lot and putting foot down will cause more damage, if below level of shoe can leave in

CV and neuro exam
sedate - alpha 2, safety consideration if distressed horse
history - known trauma, onset, exercise, when last normal, other horse, management factors (stabled?)
sigalment
coaptation - wrapping for support - sometimes not always
pre plan transport and call referral to see what they want done

immediate euthananasia if large bone fracture in an adult horse
