1
Q

TIVA

A

Total intravenous anesthesia- induction and maintenance of anesthesia using only IV agents

2
Q

PIVA

A

Partial intravenous anesthesia- induction and maintenance of anesthesia using both IV and inhalant agents

3
Q

Balanced anesthesia

A

Combination of drugs/techniques

4
Q

CRI

A

Constant rate induction

5
Q

Inhalation anesthetic things

A
  1. Equipment demanding
  2. No cummulation
  3. Easier to monitor and control anesthetic depth
  4. Safe airways, 100% O2 mechanical ventilation
6
Q

TIVA things

A
  1. Easier technique
  2. Drugs may cummulate
  3. More difficult to monitor and control anesthetic depth
7
Q

Does TIVA mean you don’t give O2?

A

NO always beneficial regardless of anesthetic technique and agent choice

8
Q

Drug administration strategies

A

Classical - give half of calculated dose slowly IV then bolus to effect

Bolus dosing- only small boluses up to effect as needed, not expected to be harmful

9
Q

Advantages of bolus/digital system

A

May induce anesthesia with smaller doses

10
Q

Disadvantages of bolus/digital system

A

First bolus may be too little

may give double dose initially if indicated

11
Q

Drug administration strategies for TIVA

A

IV boluses or CRI

12
Q

T/F: Elimination half-life of an agent after long CRI increases

A

True, accounts for cummulation effect

Depends on duration of CRI

13
Q

Ideal agent for TIVA

A
  1. Short acting
  2. Non-cummulating
  3. No active metabolites
  4. Wide theraputic window
  5. Provides smooth recovery
14
Q

Alphalaxonoe TIVA

A
  1. Does not cummulate if CRI is not super long
  2. Excessive doses may lead to prolonged recovery and dysphoria esp in cats
  3. Should combine opioid analgesics
15
Q

Etomidate TIVA

A
  1. Quick metabolism no cummulation
  2. Inhibtiion of cortisol secretion
  3. DO NOT USE
16
Q

Ketamine based TIVA

A
  1. Cummulation after large or repeated doses
  2. Triple drip good for horses (guafenesin, xylazine, ketamine)
  3. Suitable for field procedures
