Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Postoperative pain intensity after cesarean section. Timepoint: at baseline (0 hour), 2 hours, 4 hours, 6 hours, and 8 hours after surgery. Method of measurement: The primary variable (postoperative pain intensity) will be measured using the Visual Analogue Scale for pain assessment. This scale consists of a 10-centimeter horizontal line with “no pain” marked at one end (score 0) and “the worst pain imaginable” at the other end (score 10).At each predefined postoperative time point (0, 2, 4, 6, and 8 hours after the cesarean section), the patient will indicate the intensity of pain by marking a point on the line corresponding to their perceived pain level. The score is obtained by measuring the distance in centimeters from the “no pain” anchor to the patient’s mark.Before surgery, all participants will be instructed on how to use the scale to ensure a consistent and valid understanding of pain rating across subjects. | — |
