19. Features

20. Treatment of laryngospasm CPAP with 100%O2 CPAP with 100%O2 Propofol Propofol Lignocaine: topical or IV 2mg/kg Lignocaine: topical or IV 2mg/kg Sux: 2mg/kg IV or 4mg/kg IM Sux: 2mg/kg IV or 4mg/kg IM

21. Bradycardia Risk factors Risk factors –Cardiac disease –Hypoxia –Drugs esp sux –CVP insertion –Reflex eg oculo-cardiac reflex Treatment Treatment –Treat cause –Atropine: 20mcg/kg IV or IM Chest compressions if persistent Chest compressions if persistent
