Propofol Dreams App

Propofol Dreams is designed to help anaesthetists minimise propofol wastage during intravenous anaesthesia.

Volume Estimation Mode

Volume Estimation mode estimates how much propofol will be required based on the Marsh model using patient weight, duration of surgery and the average depth (CpT) required. This guides how much propofol to draw up before starting a case.

Paediatric EstimationMode

Paediatric Estimation mode estimates the propofol volume required for children age 16 years and younger using the Paedfusor model.

Duration Estimation Mode

Duration Estimation mode estimates how much more anaesthesia time that 20 or 50 mL of 1% propofol will provide at the current infusion rate. This guides how much propofol to draw up towards end of the case.

Wasted propofol can persist in water and soil and is extremely toxic to aquatic life.
