• The amount of morphine consumed on an hourly basis up to 6 hours after extubation and at 24 hours post-operatively will be collected using the computerized chart in the continuous care unit.
• The occurrence of post-operative nausea and vomiting will also be collected and defined by at least one of the following: the presence of nausea / the need for rescue antiemetic treatment / at least one episode of vomiting. This criterion is collected at 6 and 24 hours post-operatively on the basis of the data on the placard, and assessed by the nurses in the continuous monitoring unit in accordance with departmental practice.
