Brief Summary

This clinical trial examines the antidepressant efficacy and safety of a single low-dose intravenous esketamine combined with oral duloxetine in patients with postherpetic neuralgia and depression (duration more than 1 month). In this prospective, randomized, double-blind, placebo-controlled parallel study, eligible patients were randomized into two groups: one received esketamine plus duloxetine, and the other got placebo plus duloxetine. Both groups underwent standard pain management and neuro modulation therapy. The primary outcome was the Hospital Anxiety and Depression Scale - Depression( HADS-D)score at 2 weeks post - infusion, with various secondary outcomes assessed over multiple time points. Data were collected through in-person interviews and telephone follow-ups.

Ketamine with DuloxetineIntravenous Ketamine InfusionsPatients in this group received a single intravenous infusion of esketamine (esketamine at 0.2 mg/kg was added to 50 ml of normal saline and administered via a micro-infusion pump over 40 minutes), followed by 60 mg/day of oral duloxetine as maintenance therapy.
Ketamine with DuloxetineOral Duloxetine 60mgPatients in this group received a single intravenous infusion of esketamine (esketamine at 0.2 mg/kg was added to 50 ml of normal saline and administered via a micro-infusion pump over 40 minutes), followed by 60 mg/day of oral duloxetine as maintenance therapy.
Normal saline with DuloxetineIntravenous normal salinePatients in this group received a single intravenous infusion of normal saline (50 ml of normal saline administered via a micro-infusion pump over 40 minutes), followed by 60 mg/day of oral duloxetine as maintenance therapy.

Primary Outcome Measures
NameTimeMethod
Hospital Anxiety and Depression Scale - Depression score2 weeks after intravenous ketamine infusion therapy

This scale includes 7 items, and each item is scored from 0 to 3, so the total possible score ranges from 0 to 21. The cutoff scores usually are 0-7 for normal, 8-10 for mild, 11-14 for moderate, and 15-21 for severe depression.

Secondary Outcome Measures

Incidence of vomiting after administration of ketamine

HeadacheAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Incidence of headache after administration of ketamine

DiplopiaAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Incidence of diplopia after administration of ketamine

HallucinationAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Incidence of hallucination after administration of ketamine

Heart RateAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Patients' heart rate.

Peripheral capillary oxygen saturationAt 2 hours and 24 hours after intravenous ketamine infusion therapy

One of patients' vital signs.

Noninvasive blood pressureAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Patients' noninvasive blood pressure

NauseaAt 2 hours and 24 hours after intravenous ketamine infusion therapy

Incidence of nausea after ministration of ketamine

Montgomery-Åsberg Depression Rating Scale scoreOne day, one week, two weeks, three weeks, four weeks, five weeks and six weeks after intravenous ketamine infusion therapy

This scale includes 10 items, each rated from 0 to 6. The total score ranges from 0 to 60. The ranges are usually 0-6 normal, 7-19 mild, 20-34 moderate, and 35-60 severe

Hospital Anxiety and Depression Scale - Anxiety scoreOne day, one week, two weeks, three weeks, four weeks, five weeks and six weeks after intravenous ketamine infusion therapy

This scale includes 7 items, and each item is scored from 0 to 3, so the total possible score ranges from 0 to 21. The cutoff scores usually are 0-7 for normal, 8-10 for mild, 11-14 for moderate, and 15-21 for severe anxiety.

McGill pain scoreOne day, one week, two weeks, three weeks, four weeks, five weeks and six weeks after intravenous ketamine infusion therapy

The main sections of the original MPQ are the Pain Rating Index (PRI), which includes sensory, affective, evaluative, and miscellaneous descriptors. Each category has words ranked by intensity. Then there's the Present Pain Intensity (PPI) scale, which is a 0-5 rating. Higher scores indicate more severe/intense pain

NRS( Numeric Rating Scale) pain scoreOne day, one week, two weeks, three weeks, four weeks, five weeks and six weeks after intravenous ketamine infusion therapy

Rating 0-10; 0: No pain;1-3: Mild pain;4-6: Moderate pain ; 7-10: Severe pain.

Short Form-12 Quality of Life ScoreOne day, one week, two weeks, three weeks, four weeks, five weeks and six weeks after intravenous ketamine infusion therapy

The Short Form-12 Health Survey (SF-12) is a widely used, self-administered questionnaire designed to assess health-related quality of life. Range: 0-100 for each component. The more scores, the better quality of life.

Columbia - Suicide Severity Rating Scale(C-SSRS)scoreAt 2 hours and 24 hours after intravenous ketamine infusion therapy

The Columbia-Suicide Severity Rating Scale (C-SSRS) is a validated, clinician-administered tool designed to assess suicidal ideation and behavior.Rated on a 0-5 scale, higher scores mean higher risk of suicide.

Clinician-Administered Dissociative States Scale scoreAt 2 hours and 24 hours after intravenous ketamine infusion therapy

The Clinician-Administered Dissociative States Scale (CADSS) is a structured, clinician-administered tool designed to assess acute dissociative states in clinical and research settings. This scale includes 27 items, each item rated on a 0-4 scale, range: 0-108 .

0-19: Minimal/no dissociation. 20-39: Mild to moderate dissociation.

* 40: Severe dissociation (indicative of significant impairment).
