Ankle fracture Musculoskeletal Diseases
Conditions
Interventions
All patients were anesthetized using ultrasound-guided PNB with ropivacaine. Group A received PCA with ketorolac for postoperative pain management after PNB. Group B received PCA with normal saline
instead, dexamethasone and epinephrine were added to ropivacaine during PNB. The allocation sequence was concealed from the researchers and participants in sequentially numbered, opaque sealed envelop

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pain intensity (VAS score: 0, no pain; 10, worst pain imaginable) at 6, 12, 18, 24, 32, 40, 48, and 60 hours after peripheral nerve block | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The time at which the sensation began (analgesia time) and the time at which motor function was restored were recorded using patient records 2. After three days of administering pain control, a questionnaire was completed to assess patients' satisfaction with the pain control method (Likert scale). | — |
