- Post herpetic neuralgia, feels like insects crawling across head, what is it?
- Allodynia
- Dysaesthesia
- Formication
- Pruritis
Other remembered “trigeminal neuralgia, feeling of ants crawling over face”
- Allodynia
- Dysaesthesia
- Formication
Hyperpathia
Ans: Formication
Dysaesthesia “spontaneous or evoked unpleasant abnormal sensations”
Hyperalgesia “increased response to a normally painful stimulus”
Allodynia “pain due to a stimulus that does not normally evoke pain such as light touch”
- Congenital long QT, drug should avoid
- Propofol
- Thiopentone
Ketamine
Uptodate:
= Droperidol, haloperidol, volatile, ondansetron, amiodarone. methadone
Propofol has least effect. Prop/remi TIVA is safe
“ketamine should be avoided because of its sympathomimetic effects”
Glyco and atropine can prolong QTc and precipitate torsades.
Thiopental can be used in patients with prolonged QT (prolongs the QTc but reduces TDP - transmural dispersion of depolarization)
Long QT syndrome | BJA Education | Oxford Academic (oup.com)
- Recurrent torsades treatment, acceptable
- Flecainide
- Lignocaine
- Procainamide
- Amiodarone
Sotalol
Lignocaine (dose is 1mg/kg bolus - ANZCOR)
- Overdrive pacing - Lignocaine decreases the QTc - Beta blockers - Isoprenaline
Uptodate:
- If baseline QTc is normal then less likely to respond to Mg and IV amiodarone may prevent recurrence.
“polymorphic VT” = without QT prolongation
“torsades” = a form of polymorphic VT with QT prolongation
- Acceptable tryptase to diagnose anaphylaxis
- (1.2 times normal) + 2
