About this 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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Ages more than 18 years;
Patients with onset of herpes zoster (HZ) rash less than 90 days;
HZ affected the spinal nerves (cervical/thoracic/lumbar nerve);
Having an average pain score of at least 4 on a Numeric Rating Scale (NRS, 0 = no pain, 10= worst possible pain);
Disqualifiers
Obstructive sleep apnoea syndrome;
Those who receive other more invasive treatments, such as radiofrequency thermocoagulation (RFT) of DRG.

A history of severe cardiopulmonary, hepatic, renal dysfunction or coagulation function disorder;
Trial design
Parallel
Treatments tested in this trial
esketamine group
Drugin addition to receiving the combination of PRF of DRG and standardized drug treatment, patients will also undergo a single intravenous infusion of esketamine.
PRF group
DrugIn 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
Treatment groups
Trial outcomes
Primary outcomes
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
Secondary outcomes
the NRS score after treatment
Generally, 0 represents no pain, and 10 represents the most severe pain.A higher score indicates more severe pain.
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)
the Pittsburgh Sleep Quality Index (PSQI) score
Sleep quality measured by PSQI score (range 0-21, with higher scores indicating poorer sleep quality).
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
