Test 1: Lecture 1 +2 Flashcards
not perceiving pain / not
responding to painful stimuli
analgesia
risks of general anesthesia
Hypotension, bradycardia
Hypoxemia, hypoventilation
Nausea, vomiting, ileus
Hypothermia
why use premed?
reduce stress/anxiety
allow for IV placement
reduces the amount of drugs needed to induce
can be used for minor procedures or diagnostics that require sedation but not full general anesthesia
prior to induction pt should be —, and all — should be set up
pt should be sedated with patent IV access
all equipment should be set up
Pt should be pre-oxygenated
PIVA
partial IV anesthesia
use IV injectable drugs and inhaled drugs to keep pt under
cardiovascular support by — and — while under anesthesia
fluids and drugs
how to monitor depth of anesthesia
eye position/ palpebral reflex
jaw tone
cardiovascular: how HR and BP chnages in response to stimulus
respiratory
what is pt signalment
species, breed, sex, age, temperament
history should include
presenting complaint
comorbidities
current meds
past anesthetic episodes (complications, how easy where they to sedate?)
what drugs should you stop prior to sedation
Antihypertensives especially ACE inhibitors (enalapril or benazepril) (can lead to hypotensive crisis)
Anticoagulants (may need to be stopped up to 2 weeks prior)
on PE what should you check for prior to sedation
body temp
hydration status
GI (are they vomiting, making them a higher risk for aspiration)
how to check heart during sedation
membrane color
pulse
murmur
arrhythmias
pulse quality/synchronicity
ASA physical status 1-6
1: Healthy Patient
2: Mild systemic disease
3: Severe systemic disease
4: Severe life-threatening disease
5: Moribund (not expected to survive 24 hours)
6: Organ Donor
E: Emergent
level 1 ASA status
healthy patient
level 2 ASA status
mild systemic disease
