In the standard IV induction, what are the two classes of drug required to induce the anasthesia?

Analagesics

What is the hypnotic agent usually used in induction?

Propofol

7

What is the drug used in the inhalation method of induction?

Sevofluorane with O2 and air or N2O

8

When would you give a muscle relaxant in induction?

If intubation is required
If surgery requires a still patient

9

What is the classic example of a depolarising muscle relaxant?

Suxamethonium

10

What are examples of non-depolarising muscle relaxants?

Atracurium

11

What are the airway manoeuvres used once the muscle relaxant has been induced?

Chin tilt jaw thrust
Airway adjuncts
Supralottic devices
Endotracheal intubation

12

What are the general ways in which we maintain anaethesia?

Volatile agents
Intravenous maintenance

13

What is the normal method of maintenance?

Volatile agents

14

If we decided to maintain anaesthesia intravenously what two drugs would we use?

Propofol and an opioid

15

What are the factors that must be considered as part of the perioperative care?

Positions
Temperature
Fluid balance
Other drugs such as sympathetic drivers (adrenoceptor agonists and anti-muscarinics), antibiotics
Bloods

16

What are the stages of emergence?

Analgesia
Anti-emetics
Muscular function restored
Maintenance agents switched off
Extubation

What are the only two groups of drugs that might be stopped prior to an operation?

Anti-coagualants
ACE inhibitors
