What is the process of general anaesthesia?
Pre op assessment Prep Induction Maintenance Emergence Recovery Post op care and pain management
What are the methods of induction of anaesthesia?
IV
Gas
What are the commonly used IV anaesthetics?
Propofol
Thiopentone
What are the speeds of induction of anaesthesia?
IV- fast
Gas- slow
What gas anaesthetics are common?
Sevoflurane
What is used to monitor consciousness level?
Loss of verbal contact
Movement
Respiratory pattern
EEG
What are the methods for airway maintenance?
Face mask
Oropharyngeal
Laryngeal
Endotracheal intubation
When is an oropharyngeal airway not tolerated?
In conscious or lightly unconcious
What are the complications of airway maintenance?
Obstruction- often via laryngospasm
Aspiration
What is the basic monitoring under anaesthesia?
SpO2 ECG Non invasive BP FiO2 End tidal CO2
What are the additional monitoring methods in anaesthesia?
Agent monitoring Temp, urine output NMJ Invasive venous/arterial monitoring EEG
What are the risks of anaesthesia?
Airway Breathing Circulation, esp VTE Temp Loss of reflexes Pressure areas
What is plane I of anaesthesia?
Automatic respiration to cessation of eyeball movement
What is plane II of anaesthesia?
Cessation of eyeball movement to beginning of paralysis of intercostals
What is plane III of anaesthesia?
Beginning to completion of paralysis of interostals
