Non-anaesthesiologists administering propofol in the Singapore context
Dear Editor,
Propofol is a potent intravenous sedative-hypnotic agent. Its popularity for sedation has increased in the last 3 decades because of its smooth, rapid onset of action and fast post-procedural recovery.1 Nonetheless, propofol depresses cardiorespiratory function and could result in life-threatening adverse effects.
A workgroup, mainly consisting of gastroenterologists and...
