Esketamine Combined With PRF of DRG for Acute/Subacute Zoster-associated Pain

April 5, 2025 updated by: Fang Luo, Beijing Tiantan Hospital

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.

Conditions

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.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Esketamine group
Esketamine+ PRF group
in addition to receiving the combination of PRF of DRG and standardized drug treatment, patients will also undergo a single intravenous infusion of esketamine.
Other Names:
  • esketamine+PRF+ standardized drug treatment
Active Comparator: control group
PRF group
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
Other Names:
  • PRF+standardized drug treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the NRS score at 1 month after treatment.
Time Frame: 1-month period
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
1-month period

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the 12-item Short-Form Health Survey (SF-12) score
Time Frame: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
Quality of life (QoL) assessed by the SF-12 score (range 0-100, with higher scores indicating better health status)
at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
the Pittsburgh Sleep Quality Index (PSQI) score
Time Frame: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
Sleep quality measured by PSQI score (range 0-21, with higher scores indicating poorer sleep quality).
at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
The Patient Global Impression of Change scale (PGIC)
Time Frame: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
The proportion of patients with a response of "no change", "minimally improved", "much improved" or "very much improved" on PGIC
at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
Analgesics consumption
Time Frame: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment

at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
success rate
Time Frame: at 1 week, 2 weeks, 1 month, 2 months, 3 months after treatment
