Design outcomes

Primary

MeasureTime frame
We measure postoperative pain severity on coughing by Numerical Rating Scale (NRS, 0-10) after 1 hour and 2 hours of the operation. Then, we convert the NRSs to 0-100 mm scale. Our primary outcome is area under the curve of the converted NRSs.

Secondary

MeasureTime frame
Postoperative pain severity at rest measured by Numerical Rating Scale Cumulative morphine consumption Procedure duration Postoperative duration free of morphine rescue Postoperative nausea and vomiting
