Quick Flashcards
Cat 1 triage
Unconscious, likely to die without immediate
Primary life threats
CV, resp, neuro, blocked cat
HyperK of UO and Addisons caues
Atrial standstill
PCV/TS for comp/decomp shock
Comp: hyperemic/
Expiratory effort, loud/harsh, crackles
lower airway (asthma, bronchitis)
Mixed insp/exp effort, harsh sounds/crackles, short/shallow
Parenchymal (contusion, hemorrhage, pneumonia)
Insp effort, short/shallow, quiet
Pleural dz (pneumothorax, pl eff)
Insp effort, stridor
Upper airway
Dog CO dop at
180 bpm
Vacular resistance formula
inversely proportional to radius to 4th powr
Worry about a cat when
Less than 160
Contractility decreases in
Sepsis, SIRS, heart dz
Treat contractility
Sepsis/SIRS- dobutamine
Heart dz- pimobendan
Fever anatomy
Ant hypothal
What determines body hydration
Na determines total body hydration
Dehy from, hypovol from
interstitial, intercellular; intravasc
Insensible losses
Sweat, saliva 20-30 mL/kg/day
5-7% dehy
CRT normal, tacky, mild tent
8-10% dehy
long CRT, tachy, poor pulse quality
Isotonic fluids
270-350
Bolus water IV
RBC swell from intracell shift (zero tonicity)
Maintenance characteristics
Low Na, Cl, higher K- NEVER bolus
Maint fluids
Norm M, PLyte 56
Replacement characteristics
Like plasma- high Na, Cl, low K; isotonic
Replacement fluids
NormR, PL148, 0.9 salline, LRS
Hypertonic fluids- contra
Dehydrated, hyperNa
Colloid function
Hold fluid in vasc space
Albumin portion of COP in health
80%
Gibbs Donnan effect
Charge is important, molecular weight does not effect osmolality (Na and Alb same contribution to osmolality without charge)
Alb contras
P who has had human, healthy- leads to anaphyl, delayed hypersens
Use for FFP
Clotting factors > colloid
Alb deficit
estimating anmount needed to increase alb conc to a desired level
Greater effect on coag- DS or molecular weight
DS
Effect of HES
interferes with vWF and factor VIII- platelet dysfunction
Monitor colloids
COP increases with HES concentration but TS no change, false increase in USG 2-3 hours post
Why CPR
Perfuse heart and brain
BPM in CPR
10-12 breaths, 100-120HR
Hyperventilation in CPR=
decreased CO leading to increased ischemia of coronary and cerebral
Open chest indications
pleural eff, pneumo, pericardial eff, chest trauma, DOA, too large- NOT abd wall problems
Open chest CPR approac
R side 5th or 6th
Defib when
v-fib or pulseless v-fib (never asystole)
CPR drugs
Epi 0.01 mg/kg q3-5; vasopressin
Drug for bradycardia
Atropine- esp vagally mediated
When to give CaGluconate
hyperK, pre-existing hypoCa- NEVER ANY OTHERS
Inspiraton- think
upper
Expieration think
Lower
All effort think
Parenchymal
Short/shallow think
Pleural
Approach to resp emergency
Do no harm, hands off, sedate, oxygen
First choice of drug for resp emergency sedation
Torb
Parenchymal dz- cardiac caused–> Rx
Furosemide
Parenchymal dz- non-cardiac–> Rx
Bronchidilators
Indication for sedated airway exam
upper!, larynx, stridor
Thoracocentesis approach
8th or 9th
Trach approach
midline longitudinally, 2-3 rings below larnyx,
Dystocia signs
Weak cont 2-3h, strong cont >1hr, stage 2 >12h, fetal HR
Hydrops
Golden retriever with cankles/edematous vulva, excess fluid in amniotic sac occluding CaVC- caudal and ventral edema
C section drugs
pre-ox, propofol, iso, lidocaine
Dystocia drugs
Cagluc for stronger, then oxy for more frequent
Cause of eclampsia
Over-supp Ca pre-birth
Pyometra timing
Diestrus, progesterone
Blocked cat Rx
CaGluc- threshold, insulin, NaBicarb, terbutaline shifts K intracell
Rx for urethral spasm
Prazosin
Canine urehral obstruction- tx
sx or lithotripsy
Dx uroabdomen
creat 2:1, K 1.5:1
Emesis, dogs/cats
Apomorphine, xylazine
lipid sink-
Sequester toxins in lipids in bloodstream, change VOD
Ca channels and beta blockers- tox tx
IV lipid, atropine, glucoagon
benzos and barbituates- tox tx
Flumazenil
acetaminophen- type of damage, tx
liver and RBC from NAPQI conversion- NAC to increase glut avail for glucuronidation
serotonin syndrome tox tx
cyproheptadine
PPA overdose
ace and lidocaine
Albuterol bite causes
hypoK temproary
oyrethrein tox tx
methocarbamol
Trauma- early sx
diaphrag hernia, neuro wtihout pain
Trauma stable then sx
urinary rupture, neuro with pain
Shock dose fluids
dogs- 90, cats 60
Bite wounds Abx
clavamox
Head trauma effects
Cushings resopinse= hypertensive, bradycardic, increased ICP
Rollover injuries- look for
Bladder rupture, pelvic fx, body wall, diaphrag hernia
Diabetic hypoK cat tx
delay insulin 12-24h
Hypoglycemia tx
bolus 1ml/kg dex 50% PUSH
Eclampsia/hypoCa tx-
10% CaGlluc over several minutes IV
hypothyroid muxedema-
hypometabolic stat= dwon T4
Addisons crisis
Bradycardia from increased K- atrial standstill; Na:K 20:1 ratio dx; saline, DOCP
Peripheral veins for:
under 600 mOsm
Diameter or length changes flow
Diameter

Peripheral veins
Seldinger technique for

Intraoss cath location
Flat surface of medial tibia
Shock=
inadequate oxygen delivery to meet metabolic demand (consumption > delivery)
Cardiogenic shock=
