NCT06653218

Brief Summary

This is a multicenter, prospective, observational, propensity score matching, cohort, and assessor-blinded study designed to compare the effectiveness and safety of lidocaine combined Platelet-rich plasma (PRP) acting on SGB versus lidocaine alone acting on SGB in patients with CM.

Study Arms (2)

PRP+Lidocaine group

Patients will be placed in the supine position, with slightly excessive neck extension to receive stellate ganglion block (SGB). And 2.5 ml of PRP combined with 2.5 ml of 1.0% lidocaine will be injected slowly into the ipsilateral stellate ganglion under the guide of ultrasound visualization technology

Other: No interventions

Lidocaine group

Patients will be placed in the supine position, with slightly excessive neck extension to receive stellate ganglion block (SGB). And 5 ml of 1.0% lidocaine will be injected slowly into the ipsilateral stellate ganglion under the guide of ultrasound visualization technology

Other: Not have interventions

Study Population

We speculate that the reduction value in monthly headache days after PRP combined lidocaine acting on SGB is expected to 2.0, and the standard deviation (SD) for the PRP group is 9.0. Assuming a 20% rate of loss to follow-up and an additional 40% loss after PSM, a total of 200 participants will provide 90% power to use a 0.05 two tailed alpha to detect the significant difference in the monthly headache days. Three participating centers will compete to enroll patients.

You may qualify if:

  • Age between 18 to 75 years;
  • BMI between 15 and 35 kg/m2 ;
  • Diagnosed with CM in accordance with the International Classification of Headache Disorders, 3rd Edition (ICHD-3) criteria (Headache Classification Committee of the International Headache Society (IHS) The International Classification of Headache Disorders, 3rd edition. Cephalalgia. 2018 Jan;38(1):1-211);
  • Visual Analogue Scale (VAS; range, 0-10; 0 = no pain and 10 = worst possible pain; higher scores indicate more severe pain) score≥4;
  • Scheduled for lidocaine acting on SGB treatment for CM;
  • Signed informed consent.

You may not qualify if:

  • Previously received SGB treatment;
  • Combined with other types of headaches;
  • Platelet count \<105\*109/L, use of anticoagulants or antiplatelet agent, coagulation disorders or bleeding disorders;
  • Infection or mass near the puncture site;
  • A history of other neurological disorders;
  • A history of severe cardiopulmonary, hepatic or renal dysfunction;
  • A history of psychological disorders;
  • A history of narcotic drug abuse;
  • Changes in neck anatomic structure caused by radiotherapy or surgery;
  • A history of allergies to any research drugs;
  • Pregnancy or lactation period.
