- 1NGT or IDC size Calculation= 2x ETT size
where ETT size = (Age/4) +4 - 2ETT size calculation General(Age/4) + 4
- 3ETT size neonates<28 weeks: size 2.5
28 to 34 weeks: size 3
34 to 38 weeks: size 3.5
Term: size 4 - 4Mean arterial pressure (MAP)= [(2xDBP)+SBP]/3
= (pulse pressure/3) + DBP - 5Pulse pressure= SBP minus DBP
- 6Insertion depth ETT cm Calculation(ETT size) x3
- 7Shock index= HR/SBP
Normal 0.5 to 0.7 - 8ICC size in kids Calculation= 4 x ETT size
- 9Paeds weight Calculation= 2x(age + 4) or (age x 3) + 7
- 10Troubleshooting ventilatorDOPES: Displaced/Obstructed ETT, Pneumothorax, Equipment failures, Stacking (breaths)
- 11Drug doses in obesity Use TOTAL weight in calcsFAT MEN SUX: Fentanyl, Atracurium, Thiopentone, Midazolam, Etomidate, Narcan, Suxamethonium
- 12Drug doses in obesity Use lean weight in calcsKetamine
Propofol

Tidal volume - 138.4% sodium bicarb uses1. Cardioprotection (TCA, propranolol, Na blockers)
2. Decr CNS redistribution (salicylates)
3. Incr urine elim (salicylates, phenobarb), incr urine solubility (MTX)
4. Life threatening acidosis (pH <7.2) : cyanide, isoniazid, toxic alcohols
5. Severe hyponatraemia - 148.4% sodium bicarb Dose in severe hyponatraemiaIf seizures, 50mL (=50mmol), can repeat.
Aim Na 120 or stop seizures then stop replacing.
Aim Na increase 10mmol/L per day, 1mmol/L/hr - 153% sodium bicarb Dose in severe hyponatraemiaIf seizures, 250mmol in 10 min
Will incr Na by 7. Aim Na 120 or stop seizures then stop replacing.
Otherwise: 50mmol/hr = 1 to 2mL/kg/hr - 16DCR joules50J flutter
100J AF - 17Antiarrhythmic doses Fleicanide2mg/kg infusion
Only if normal LVEF with no CAD - 18Antiarrhythmic doses Sotalol1mg/kg infused over 15 mins
Can repeat once
Then 80 to-160mg IV over 2/24
(PO 40 to 160mg BD) - 19Antiarrhythmics Which to use Atrial vs ventricular rhythmsAtrial: amiodarone, fleicanide
Ventricular: amiodarone, sotalol - 20Chemicals NOT for water irrigationPhenols (polyethylene glycol)
