Design outcomes

Primary

MeasureTime frame
The primary outcome variable is pain intensity during surgery and 24 hours after surgery. Pain intensity was assessed using the Visual Analogue Scale (VAS). Timepoint: Pain intensity will be measured during the surgery and at 24 hours post-surgery. Method of measurement: Pain intensity will be measured using the Visual Analogue Scale (VAS).
