Conduct of General Anaesthesia Flashcards
three stage of anaesthesia
induction –> maintainence –> recovery
two IV general anaesthetics
propofol and thiopentone
how is general anaesthesia induced
in a quiet space by inhalation or IV under careful monitoring
planes of anaesthesia
analgesia and sedation –> excitation –> light –> deep –> overdose
how do you monitor the consciousness level during induction
loss of verbal and movement
changing resp pattern
processed EEG
planes of anasethesia
what is triple airway manouvre for
to maintain the airway under GA
what ist he triple airway manoeuvre
head tilt, chin lift and jaw thrust
3 types of apparatus used to ventilate/intubate
face mask
oropharyngeal (guedel) airway
laryngeal mask airway
which tool for airway maintainence doesn’t protect from aspiration
laryngeal mask
complications from intubation
laryngospasm
aspiration
ineffective trip am or airway device malposition
what does it mean to protect the airway
keep it from contamination i.e from aspiration
monitoring during anaesthetic (maintainence)
SpO2 ECG BP Respiratory rate temperature urine output venous and arterial monitoring processed EEG
complications of GA
awareness, apnoea, respiratory depression
risk factors for awareness
muscle relaxants and ventilated Hx of awareness chronic CNS depressant use major trauma GA C-section
anaesthetic choice in c-section
NOT opioids because they can depress the baby’s respiration
common problems when coming around from anaesthetics
pain, nausea and vomiting
difficult regaining respiratory function
order of functioning lost during induction
complex first (speaking etc) - simple last (reflexes)
machine used to infuse induce IV GA
Target Controlled Infusion (TCI)
what must happen before intubation is removed
airway control and reflexes
