Flashcards in Fundamentals of anaesthetics Deck (21)
Are the following general, topical or regional?
a) Spinal anaesthesia?
b) EMLA skin cream?
c) brachial plexus block
What are the 3 elements to anaesthesia? (A's)
What induction agent should be used for a patient requiring a burn dressing change?
Ketamine: useful for single short procedures.
- dissociative anaesthesia
- slow onset (90 secs)
- Cardiostable (rise in HR/BP
- Good analgesic properties
- emergence phenomenon (hallucinations)
Which induction agent is best used for a patient undergoing an GA operation with a laryngeal masked airway?
What does of propofol should be used?
How often used?
Commonly used (95%)
-Excellent suppression of airway reflexes (putting in LMA)
- Drop in HR and BP
- Pain on injection
What induction agent can be used for a patient with a history of heart failure requires a general anaesthetic?
Etomidate (haemodynamically stable)
- Haemodynamically stable use for heart conditions
- Rapid onset
- Low incidence of hypersensitivity
- Pain on injection
- Adreno-corticol suppression > lower cortisol > lower BP > never use for septic shock. Cortisol low for 72 hours.
- High incidence of PONV
What induction agent do you use for a patient with intestinal obstruction requires an emergency laparotomy?
Thiopentone (used for rapid sequence induction)
- Rapid Sequence Induction (faster than propofol
- Anti-epileptic properties and protect brain
- Drops BP and rise in HR
- No analgesic property
- Hangover effect
CI in prophyria
All inhalation agents end in what?
Which inhalation agent is used for long operations as rapid onset and offset.
Which inhalation agent is commonly used for paediatrics?
Which inhalation agent is best for organ retrieval from a donor?
Which two inhalation agents have low potency and low solubiluity?
Sevoflurane and desflurane
Name a depolarising muscle relaxant.
What problems are associated with suxamethonium
Hyperkalaemia > arrythymias
When is it used?
Rapid Sequence induction.
What drugs are used to reverse anti-muscarinics?
Neostigmine & Glycopyrrolate
Which drug do you use if BP and HR are low?
How does it work
Rises HR which increases BP
