About this study

Official title: Esketamine Intravenous Infusion Combined With Pulsed Radiofrequency of Dorsal Root Ganglion for Acute and Subacute Herpes Zoster Neuralgia: A Randomized Controlled Trial

To assess the 1-month effects and safety of esketamine - PRF -standardized drug treatment against PRF -standardized drug treatment acute/subacute zoster-associated pain (ZAP) patients.

Read the detailed description

This study aims to determine whether the addition of esketamine to PRF - standardized drug treatment can improve 1 - month pain control and safety profiles in acute/subacute ZAP patients. The findings may help optimize current treatment strategies for refractory ZAP patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • esketamine groupDrug

    Also called esketamine+PRF+ standardized drug treatment

    in addition to receiving the combination of PRF of DRG and standardized drug treatment, patients will also undergo a single intravenous infusion of esketamine.

  • PRF groupDrug

    Also called PRF+standardized drug treatment

    In the control group, patients will receive PRF+standardized drug treatment. Pulsed radiofrequency (PRF) will be performed on DRG by an designated physician in each participating center. They will be treated with PRF (PMG-230, Baylis Medical Inc.) using a 21-gauge sterilized radiofrequency needle (a 10-cm trocar with a 5-mm active tip, PMF-21-100-5, Baylis Medical Inc.), which are carefully inserted until the needle tip reaches the upper edge of the intervertebral foramen. The parameters of PRF treatment will be set at 42 ℃, 2 Hz with 20 milliseconds current. The standardized drug treatment will include antiviral therapy, anticonvulsant treatment, three-step analgesic therapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the NRS score at 1 month after treatment.

    The Numeric Rating Scale (NRS) score is a way to quantify the degree of subjective feelings such as pain using numbers. Generally, 0 represents no pain, and 10 represents the most severe pain.A higher score indicates more severe pain

    Measured: 1-month period

Secondary outcomes (7)
  1. the NRS score after treatment

    Generally, 0 represents no pain, and 10 represents the most severe pain.A higher score indicates more severe pain.

    Measured: at 1 week, 2 weeks, 2 months, 3 months after treatment

  2. the 12-item Short-Form Health Survey (SF-12) score

    Quality of life (QoL) assessed by the SF-12 score (range 0-100, with higher scores indicating better health status)

    Measured: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment

  3. the Pittsburgh Sleep Quality Index (PSQI) score

    Sleep quality measured by PSQI score (range 0-21, with higher scores indicating poorer sleep quality).

    Measured: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment

  4. The Patient Global Impression of Change scale (PGIC)

    The proportion of patients with a response of "no change", "minimally improved", "much improved" or "very much improved" on PGIC

    Measured: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment

  5. Analgesics consumption

    the type of analgesics and analgesics consumption

    Measured: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment

  6. Safety assessments

    intraoperative complications, PRF-related complications, esketamine-related complications

    Measured: at 0 day, 1 day, 1 week, 2 weeks,1 month, 2 months, 3 months

  7. success rate

    The success rate is defined as more than a 50% reduction in NRS-11 score

    Measured: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
