Summary
Comparative study between pulsed radiofrequency in suprascapular nerve or bupivacaine block for chronic shoulder pain
Detailed description
Prospective, randomized, comparative study of 40 participants with chronic shoulder pain allocated into two groups. Patients in group 1 underwent pulsed RF (180sec, with a fixed temperature at 42C, twice) on the suprascapular nerve, and the other group, 2, underwent nerve block with bupivacaine (5ml). After the procedure, patients were evaluated for 3 months regarding pain intensity, shoulder range of motion and dose of rescue opioids.

Interventions
| Type | Name | Description |
|---|---|---|
| DRUG | Suprascapular nerve block with bipuvacaine | Suprascapular nerve block with Bipuvacaine: a 50mm 22G needle (Stimuplex, BBraun) was introduced up to the suprascapular fossa, guided by ultrasound, and the location was confirmed by motor stimulation with contraction of the supraspinatus and infraspinatus muscles. Next, 5 ml of 0.25% bupivacaine with adrenaline was injected. |
| PROCEDURE | Pulsed radiofrequency | After confirming the location, the needle mandrel was removed and the radiofrequency cannula was introduced through the needle, 2ml of 1% lidocaine without epinephrine was injected, followed by application of pulsed radiofrequency for 180sec at 42°C by radiofrequency (radiofrequency generator system BMS-50N, Bramsys). |
