Conducting anaesthesia

Question 1

What are the 4 stages of general anaesthesia?

Answer 1

Induction
Maintenance
Emergence
Recovery

Question 2

Which measures must be monitored before GA is given?

Answer 2

ECG
Oxygen saturation
NIBP
End tidal CO2
Airway pressure

Question 3

Why do we give supplemental oxygen?

Answer 3

Increase time to desaturation

Reduced Functional Residual Capacity under anaesthesia

Question 4

What are some common analgesics for GA?

Answer 4

Fentanyl

Alfentanil

Question 5

What are some common hypnotics for GA?

Answer 5

Propofol
Thiopentone
Ketamine

Question 6

What is a Guedel airway?

Answer 6

AKA oropharyngeal airway

Airway adjunct used to maintain a patent airway. The airway prevents the tongue from obstructing the airway

Question 7

What is the difference between laryngeal mask airway and endotracheal tube?

Answer 7

LMAs are less invasive, decrease airway trauma, decrease neck mobility requirements, and have a reduced risk of laryngospasm and bronchospasm

Question 8

Does blood pressure normally rise or fall under anaesthesia?

Answer 8

Fall

Question 9

What are some reasons to intubate?

Answer 9

Protection from aspiration
Need for muscle relaxation
Shared airway
Need for tight C02 control
Minimal access to patient

Question 10

What are some of the biggest risks we work to prevent with anaesthesia?

Answer 10

Awareness
Eye trauma
Hypothermia
Pressure injury
Nerve injury
Thromboembolism

Question 11

What are the main factors controlled for anaesthetic maintenance?

Answer 11

Vapour ("gas")
Intravenous anaesthesia (TIVA)

Question 12

What are some documentational responsibilities of the anaesthetist?

Answer 12

Prescription record
Observation chart
Ventilation chart
Fluid balance

Question 13

What are the main things done for “emergence”?

Answer 13

Signed out of theatre
Reverse NM blockade
Anaesthetic agent stopped
Transfer to recovery room
