Q

What do you need to monitor when someone is under anaesthesia?

A
  • ECG
  • Oxygen saturations
  • Non-invasive blood pressure (NIBP)- Blood pressure often drops due to anaesthesia
  • End Tidal C02 (ETC02)- Amount of C02 gas a patient is breathing out, indicates patency of airways and how much C02 in a patient’s blood
  • Airway pressure

Ketamine

17
Q

What are the stages between consciousness and unconsciousness called?

A

Guedel planes of anaesthesia

18
Q

How many stages are there in Guedel planes of anaesthesia?

A

4 stages

19
Q

What is stage 1 in Guedel planes of anaesthesia?

A

Analgesia and amnesia- feel floaty and relaxed

20
Q

What is stage 2 in Guedel planes of anaesthesia?

A

Delirium and unconsciousness

21
Q

What is stage 3 in Guedel planes of anaesthesia?

A

Surgical anaesthesaia

22
Q

What is stage 4 in Guedel planes of anaesthesia?

A

Apnoea and death-want to avoid

23
Q

Why do all patients anaesthetised require airway management?

A
  • Anaesthesia will relax the upper airway and cause soft tissue collapse
  • Leads to some degree of airway obstruction
24
Q

What are possible reasons to intubate a patient under anaesthesia?

A
  • Protection from aspiration
  • Need for muscle relaxation
  • Shared airway
  • Need for tight C02 control
  • Minimal access to patient
25
Q

Why is airway management important?

A

Loss of airway reflexes lead to relaxation of tissues

26
Q

What are possible risks of general anaesthesia?

A
  • Anaphylaxis
  • Regurgitation and aspiration
  • Airway obstruction and hypoxia
  • Laryngospasm
  • Cardiovascular instability
  • Rarely, cardiac arrest
27
Q

What eye injury can occur under general anaesthesia?

A

Corneas dry out from a lack of blinking

28
Q

What is used to prevent VTE from occurring?

A

TED stockings

29
Q

What can hypothermia cause?

A

Low body temp increases the risk of surgical infection and post-operative pain

30
Q

Which nerves are at risk of damage under general anaesthesia?

A

Peripheral

Especially Ulnar and perineal

31
Q

What is does emergence involve?

A
  • Reverse of neuromuscular blockade
  • Return of spontaneous breathing
  • Return of airway reflexes
  • Suctioning and removal of airway device
  • Transfer to recovery room
