Pharmacokinetics in children

Propofol is 98% bound to plasma proteins. Propofol is widely distributed and rapidly cleared from the body. Clearance occurs via metabolic processes, mainly in the liver, and is there dependent on blood flow to form inactive conjugates of propofol and its metabolite quinol, which are excreted in the urine [SmPC Propol Lipuro].

After a single dose of 3 mg/kg administered intravenously, propofol clearance per kg body weight with increase in age as follows: The mean clearance was in neonates < 1 month (n=25) (20 mL/kg/min) significantly lower compared with older children (n=36, age between 4 months – 7 years). In addition, interindividual variability was significant in neonates (3.7-78 mL/kg/min). In older children, the mean propofol clearance after a single bolus injection of 3 mg/kg was 37.5 ml/min/kg (4-24 months) (n=8), 38.7 ml/min/kg (11-43 months) (n=6), 48 ml/min/kg (1-3 years) (n=12), 28.2 ml/min/kg (4-7 years) (n=10) compared with 23.6 ml/min/kg in adults (n=6) [SmPC Propol Lipuro].

In (premature) neonates, the following median (range) pharmacokinetic parameters were found after an IV bolus of 3 mg / kg (Allegaert, de Hoon et al. 2007, Allegaert, Peeters, et al. 2007):

Cl (ml/min/kg) 13,6 (3,7-78,2) 19,6
Vd (l/kg) 3,7 (1,33-7,96) 5,56

The following average pharmacokinetic parameters were found in older children (4 months to 12 years) (Murat et al. 1996, Raoof et al. 1995, Saint-Maurice et al. 1989):

      • Extra bolus up to 1 mg/kg can be administerred if stronger sedation is required.

Renal impaiment in children > 3 months

GFR ≥10 ml/min/1.73m2: Dose adjustment not required.

GFR <10 ml/min/1.73m2: A general recommendation on dose adjustment cannot be provided.

Side effects in children

When used as a sedative in children less than 16 years of age, serious side effects such as metabolic acidosis, hyperlipidemia, rabdomyolysis and heart failure have been reported, sometimes with fatal outcome. These side effects may occur together in the context of ‘’propofol infusion syndrome’’.

The complete list of all contra-indications can be found in the national Summary of Product Characteristics (SmPC) – click here

Contra-indications in children

Propofol product information lists hypersensitivity to soy and peanut as a contraindication. The literature indicates that allergic reactions to propofol are rare, the amounts of food proteins in a propofol product are negligible, and a history of food allergy is not a predictor of propofol allergy [Sommerfield 2019; Murphy 2011; Bagley 2021; Wiskin 2015; Gelberg 2019]

Warnings & precautions in children

Cavebloodpressure drop with rapid injection. Painful when administered: possibly add lidocaine. Propofol lipuro is less painful when injected than propofol.

Propofol is a lipid formulation. This can cause hyperlipidemia. Children are at greater risk for "fat overload" syndrome (pay particular attention when on a ketogenic diet). Monitor plasma lipid levels.

Cave propofol infusion syndrome.

Be reluctant in children with (suspicion of) mitochondrial disorders, severe cachexia and hemodynamic instable patients.
