Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Postoperative pain intensity at 2, 6, 12, and 24 hours after surgery based on the visual analog scale (VAS). Timepoint: At 2, 6, 12, 24 hours after surgery. Method of measurement: Using a visual analogue scale (VAS) of pain by a pain assessor who is unaware of the patient grouping.;Changes in vital signs (blood pressure, heart rate, oxygen saturation) in the hours after surgery. Timepoint: Measurement by pain assessor at 2, 6, 12, and 24 hours after surgery. Method of measurement: % -mmhg-bpm.;Possible complications with the block, such as hematoma, pneumothorax, and hypotension. Timepoint: Clinical assessment and recording during the 24 hours after surgery. Method of measurement: Incidence percentage. | — |
Secondary
| Measure | Time frame |
|---|---|
| Amount of pain medication used within 24 hours after surgery. Timepoint: Record the total amount of painkillers prescribed, such as diclofenac, acetaminophen, or other narcotics, in the patient's record within 24 hours after surgery.
