Brief summary
The purpose of this study was to investigate the preemptive effect of ultrasound guided popliteal scistic nerve block on postoperative acute pain in patients with bilateral hallux valgus. After induction of general anesthesia, the leg to be operated first is decided randomly. After the operation of one leg is completed, PSNB is performed on both legs with 0.2% Ropivacaine and surgery is started on the remaining legs. When the surgery is over, check to see which foot pain begins first, how strong the pain is, and whether there are any side effects.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analgesic duration of nerve block | at 0, 0.5, 1, 4, 8, 12 hours after operation. And AM 9 and PM 5 of POD (Post Operative Day) 1 | The difference of NRS during study time between group preB and group postB The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain. It is for adults and children 10 years old or older. 0: No pain, 1-3: mild pain, 4-6: Moderate pain, 7-10: severe pain, 10: worst pain imaginable. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference of analgesic consumption between both group | at 0, 0.5, 1, 4, 8, 12 hours after operation. And AM 9 and PM 5 of POD (Post Operative Day) 1 | The difference of usage of rescue analgesics during study time between group preB and group postB after the operation |
| side effect of popliteal sciatic nerve block | at 0, 0.5, 1, 4, 8, 12 hours after operation. And AM 9 and PM 5 of POD (Post Operative Day) 1 | any other sensation except pain |
