P is a lipidic emulsion used intravenously for induction and maintenance of anaesthesia. Its effect begins rapidly and ends faster than midazolam (M). The main advantage of P is therefore a faster recovery of mnesic, cognitive and motor functions, whereas M induces anterograde amnesia (1-2 h after bolus) and slower motor reaction . This gives to P a keen interest in ambulatory practice. While P is commonly and safely used in several gastroenterological endoscopic procedures, its use by pneumologist is currently hampered by a lack of expertise and could benefit from collaboration with the anaesthesia team.
