Case Reports on the Effect of Stellate Ganglion Block in Patient with Postherpetic Neuralgia Accompanied by Itching

Abstract

Herpes zoster is a disease that involves reactivation of the varicella-zoster virus and induces pain by injuring the nerve ganglia. We present the case of a 52-year-old woman without a notable medical history. She complained of painful itches that were causatively associated with infiltration to the ophthalmic nerve of the trigeminal nerve. Furthermore, the patient did not positively respond to antiviral agents, analgesics, and anticonvulsants. However, after inducing a stellate ganglion block, her Visual Analog Scale for pain and itching reduced from a scale of 8 to 2.

Efficacy of different interventions for the treatment of postherpetic neuralgia: a Bayesian network meta-analysis

“…Table 1 describes the summary of the 12 included studies that were published between 2010 and 2017. 15–26 There were 702 participants with an age range from 57.06 to 73.53 years. Among these included studies, two focused on the efficiency of subcutaneous BTX-A, 21,26 three focused on NB, 15–17 five studies focused on PRF therapy, 15,16,19–21 one study focused on PRF + NB, 17 one study focused on PRF + NB + SC, 19 three studies focused on SC, 23,24,26 one study focused on SC + NB, 24 one study focused on SC + NB + O3 injection, 24 and one study focused on SGB.…”

“…25 The detailed parameters, methods, and drug dosages are listed in Table 1. For oral medication, among nine studies, 16–24 all patients regularly took oral calcium channel regulators (first-line drugs for PHN treatment); however, in one study, 25 only some patients took calcium channel regulators, while in two studies, 26,27 no patients took these medications.…”

“…Studies included in our NMA were assessed using the Cochrane Collaboration’s tool for assessing the risk of bias (Figure 2). All 12 of the included studies reported all of the results, and most studies 16–22,24–27 described how the random sequence was generated and showed all of the outcome data. Half of the included studies 19–22,26,27 showed their allocation concealment method and outcome concealment strategy, while two studies 19,23 did not perform blinding for their participants and personnel.…”

The publication bias for the included studies is shown in Figure 3.…”
