What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative Pain
Time Frame: 4, 12, 24, 36 and 48 hours after surgery
A questionnaire with a numeric rating scale (NRS) is used to evaluate pain intensity at 4, 12, 24, 36 and 48 hours postoperatively to assess pain intensity. The scale includes even numbers from 0 to 10, where 0 signifies no pain, and 10 signifies the worst imaginable pain.
4, 12, 24, 36 and 48 hours after surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative Nausea
Time Frame: 4, 12, 24, 36 and 48 hours after surgery
A questionnaire was used to evaluate nausea at 4, 12, 24, 36 and 48 hours postoperatively. The questionnaire involved a numeric rating scale (NRS) from 0 to 10, where 0 signified no nausea, and10 the worst imaginable nausea.
