Anesthesia

Question 1

Clark-Price
Change Rectal Temp Under Anesthesia
JAVMA 2021

Answer 1

89% decreased temp
Assoc with
~Lower weight
~ASA >2
~Ortho/Neuro
~MRI
~Alpha2
~u-opioid
~longer anesthesia

Less heat loss
~lack of u-opioid
~shorter anesthesia

Question 2

Cazlan
Effects of 2% Lidocaine as Co-Induction agent with Propofol
JAVMA 2020

Answer 2

Pulse ox lower in Lidocaine group

No sign different in propofol induction dose

Question 3

Hampton
Recovery with various protocols
JAVMA 2019

Answer 3

Recovery score better with propofol or alfaxalone than telazol or ket/val

Question 4

Martin-Flores
Preop Ace or DexMed
JAVMA 2019

Answer 4

odds for hypotension
~Ace 2.61x
~earlier and longer with Ace
~more frequently treated with dopamine

Lower BW assoc with hypotension

Bradycardia
Dexmed
Prop or KetVal vs Thio

Question 7

Fantoni
Compare CV effect of Ventilation under Anesthesia
JVECC 2016

Answer 7

Pressure controlled ventilation
~higher static compliance
~lower Peak Insp Pressure

over volume-controlled ventilation

Compared with spontaneous ventilation, both groups had decreased alveolar-arterial oxygen difference

Equation for MAP

Answer 8

(Cardiac output x vascular resistance) + AP
