## What is Propofol Dreams?

Propofol is one of the most commonly wasted drugs in the operating theatre. It is toxic to the aquatic environment, bioaccumulates up the food chain and is not readily degraded in nature.

Propofol Dreams is a simple app designed to help anaesthetists minimise propofol wastage during TIVA.

Propofol Dreams has three main modes:

(1) Volume Mode estimates the volume of propofol required for a given case based on the TCI model, patient parameters and the estimated duration of surgery. This guides the volume of propofol to draw up at the beginning of a case.

(2) Duration Mode estimates how long a syringe of propofol will last at the current infusion rate. This guides the volume of propofol to draw up in the middle of a case.

(3) EleMarsh Mode makes the Marsh Model on your TCI pump behave like the Eleveld Model through adjusting the input weight using our novel algorithm.

We are passionate about environmental sustainability in anaesthesia and we hope to tackle these issues through technology. Please help us make Propofol Dreams better!

Thank you and happy propofol dreaming!

Important Note: Propofol Dreams is designed for the purposes of education and environmental sustainability only. It is not a dosage calculator and does not give advice about the clinical care of patients. Propofol Dreams cannot be used to replace infusion pumps or sound clinical judgment.
