Abstract
AimTo analyse the effects of different propofol starting doses as premedication for endotracheal intubation on blood pressure in neonates.MethodsNeonates who received propofol starting doses of 1.0 mg/kg (n = 30), 1.5 mg/kg (n = 23) or 2.0 mg/kg (n = 26) as part of a previously published dose‐finding study were included in this analysis. Blood pressure in the 3 dosing groups was analysed in the first 60 minutes after start of propofol.ResultsBlood pressure declined after the start of propofol in all 3 dosing groups and was not restored 60 minutes after the start of propofol. The decline in blood pressure was highest in the 2.0 mg/kg dosing group. Blood pressure decline was mainly dependent on the initial propofol starting dose rather than the cumulative propofol dose.ConclusionPropofol causes a dose‐dependent profound and prolonged decrease in blood pressure. The use of propofol should be carefully considered. When using propofol, starting with a low dose and titrating according to sedative effect seems the safest strategy.
