ANAESTHETICS Flashcards
INDUCTION AGENT: (KEPT)
PROPOFOL
1.5-2.5 lower PO N+V PROPERLY Supresses airway reflexes Pain on injection involuntary movements decreases HR + BP
INDUCTION AGENT: (KEPT)
THIOPENTONE
4-5
fast –> RAPID SEQUENCE INDUCTION
(thigh-o-pentone = thighs needed for fast running - build up lactic acid = porphorpyia = build up of porphoryins)
- antiepileptic and protects brain
does NOT suppress airway
increase HR decrease BP!! so cant use if low bp
XXXX IN porphoryia
- S/E rash + bronchosplasm
careful use intarterial as risk of thrombosis and gangrene
INDUCTION AGENT: KETAMINE: (KEPT)
1-1/5 SLOW ONSET - used for short procedures increase HR and bP N+V AND EMERGENCE phenomenom dissociative amnesia - Preserves blood pressure and does not cause cardiosuppression = better in low BP RSI
INDUCTION AGENT: (KEPT)
- Etomidate
0.3 HAEMODYNAMICALLY STABLE Decreased allergic reactions GOOD in limited cardiac resevre patients highest PO N+V
INHALATIONAL ANAESHTHETICS - amnesia maintainance
- SIDE
SEVOFLURANE
2% dont need IV
“sweet smelling = inhailed”
INHALATIONAL ANAESTHETICS - amnesia maintainance
- SIDE
ISOFLURANE
1.5%
least affect on blood flow
= “iso’ tonic affect on blood flow
INHALATIONAL ANAESHTHETICS - amnesia maintainance
- SIDE
DESFLURANE
6%
DESparately longer operations
DESparately slow
rapid onset and offset
INHALATIONAL ANAESHTHETICS - amnesia maintainance
- SIDE
ENFLURANE
1.6%
MUSCLE RELAXANT
DEPOLARISING
- Suxamethonium = 1-1.5, rapid onset and offset
= USED FOR RAPID SEQUENCE INDUCTIONS
X increases potassium + pressure in brain, eyes and gastric pressure
Causes MALIGNANT HYPERTHERMIA + Muscle pains
Treat the malignant hyperthermia with DANTROLENE
MUSCLE RELAXANT
Examples of names?
NON-DEPOLARISING = Nicotinic receptors
Reversed with???
Short: Atravarium, mivacarium
intermediate: vercuronum
Long: pancuronium
-SLOW ONSET
VARIABLE DURATION
LESS SIDE EFFECTS
Reversal with NEOSTIGMINE + GLYCOPYROLATE
LOCAL ANAESTHETICS
LIGNOCAINE
3 –> 7 with adrenaline
medium acting
amide
LOCAL ANAESTHETICS
BUPIVACAINE / LEVOBUBPIVACAINE
2–> 2 same with adrenaline
long acting
amide
LOCAL ANAESTHETICS
Prilocaine
6–> 8 with adrenaline
short acting
Esther
VASOACTIVE DRUGS
- Ephedrine increases HR + BP
- other 2 phenylepherine and metaraminol increase BP but decrease HR
- adreanaline and noradrenaline used in ICU
