Study Arms:
- treatment (Type: EXPERIMENTAL): Any patient alternatively receive both remifentanil and isotonic saline (placebo)infusion. The order of infusion is randomized. An interval of 30 minutes is planned between the two infusions.

Based on this trial design, predict the completion outcome and termination type (if applicable).
