研究组 & 干预措施
Group of Greater Occiptal nerve Block , GONB
Active Comparator
Injection Procedure:
- Local skin infiltration with 1-2 mL of 1% lidocaine at puncture site.
- GON block using 3-5 mL of local anesthetic, optionally combined with 20-40 mg triamcinolone ( Bilaterally )
- Needle placement confirmed by ultrasound visualization of the nerve and spread of injectate.
- Observe patient for 15-20 minutes post-injection for immediate adverse events.
干预措施: Greater occiptal nerve block (Drug)
Group of Pulsed Radiofrequency , PRF
Active Comparator
- Introduce RF cannula adjacent to GON under ultrasound guidance.
- Confirm sensory stimulation: paresthesia at occipital scalp at <0.5 V.
- PRF settings:
- Temperature: ≤42°C
- Pulse duration: 20 ms
- Frequency: 2 Hz
- Duration: 120 seconds per cycle, 2 cycles per side
- Continuous monitoring of patient comfort and vital signs.
干预措施: Pulsed radiofrequency (Device)
结局指标
