Advances in health care require that more children are given sedation to allow doctors to perform investigations or minor procedures. Sedation drugs have traditionally been given orally (swallowed) by children. However, oral sedation drugs have unpredictable characteristics, such as duration of sedation, which may result in difficulties performing the planned procedure.
Anesthetic drugs are now invariably used for sedation in children. These are given through an IV (skinny plastic tube inserted in to a vein). Propofol (white liquid) is the anesthetic drug most commonly used for sedation at BC Children's Hospital for sedation. Propofol has several advantages, including an accurately controllable depth of sedation (how deeply asleep), minimal effect on the heart and circulation and control of reflexes (e,g coughing) during the procedure. Propofol also promotes rapid recovery with less sickness and an earlier return to normal functioning following the procedure.
While propofol has many advantages it can cause respiratory depression (reduced breathing rate). This reduction in breathing is more common if propofol is given quickly. When your child is given propofol for their proposed procedure this is performed by a pediatric anesthesiologist who is skilled in supporting breathing should this be required. If your child does not participate in this study they will still receive propofol administered by the anesthesiologist as this is our usual practice. It would be routine to administer the propofol rapidly and then support breathing for a few minutes. This is very safe in the hands of an expert anesthesiologist but can be sometimes more risky in other settings where extensive monitoring and anesthesiologists are not available. This is the setting that propofol is used in many institutions.
Our goal is to determine how quickly propofol can be given without reducing breathing to the point that help with breathing is required.

Active Comparator: 1
Propofol 1 % at a dose of 4mg/kg will be administered intravenously via a standard Medex Protégé® 3010 (Medex-A Furon. Healthcare Company, Duluth, GA, USA) infusion pump at a constant rate determined by the randomization schedule. Fresh gas flow will be maintained at 6 l/min throughout the induction procedure with the FiO2 increased to 0.5. Full cardiovascular, respiratory and EEG monitoring will continue during induction of anesthesia.
Once the loading dose of propofol has been delivered the propofol infusion will be maintained at a rate of 200mcg/kg/min or as determined by the attending anesthesiologist whilst the end-point respiratory responses are observed.

Active Comparator: 2
Same procedure as above. These subjects will be stratified by age and randomized, using the Biased Coin Design (BCD) principle to determine the infusion rate of propofol for delivery of the induction dose.
See detailed description
- Positive result: Spontaneous ventilation continues following administration of the full loading dose of propofol by infusion. [ Time Frame: Before and during surgery ]
- Negative result: Apnoea occurs (no breath for 20 seconds or oxygen saturation less than 90%) before the complete dose is administered or within 4 minutes of the end of the dose. [ Time Frame: Before and during surgery ]
