Herpes zoster pain, encompassing both acute and chronic forms such as post-herpetic neuralgia, represents a significant global health burden. This debilitating condition arises from the reactivation of the varicella-zoster virus (VZV), leading to nerve damage and persistent discomfort that can last for months or even years. The incidence and severity of herpes zoster pain tend to increase with age, imposing substantial physical, social, and emotional challenges on affected individuals. Given the profound impact on patients' quality of life, effective pain management strategies are paramount. Patient-controlled analgesia (PCA) is an established method recognized for its ability to empower patients to manage their own pain, often resulting in superior efficacy compared to conventional analgesic approaches. However, there is a notable scarcity of dedicated research in Vietnam specifically evaluating the effectiveness of PCA with Fentanyl in treating herpes zoster pain, which this study aims to address.

Medical professionals, dermatologists, pain management specialists, general practitioners, and researchers interested in herpes zoster and pain control.

This cross-sectional descriptive study aimed to evaluate the efficacy of patient-controlled analgesia (PCA) using Fentanyl for managing herpes zoster pain. Conducted at the National Hospital of Dermatology in Hanoi from January 2023 to December 2024, the study included 68 patients diagnosed with herpes zoster pain. The findings demonstrate that PCA with Fentanyl is highly effective in controlling herpes zoster pain, particularly in the initial stages of treatment. After just three days, 86.8% of patients reported mild pain, and this sustained analgesic effect continued for up to 12 weeks, with 82.4% of patients still experiencing mild pain, a significant improvement compared to pre-treatment conditions where no patients reported mild pain. The study highlights that PCA with Fentanyl provides superior and lasting pain relief for individuals suffering from shingles. While highly effective, common side effects observed included dizziness, nausea, and vomiting in 17.7% of patients, and urinary retention in 8.8%, along with a few cases of lethargy and constipation. The research concludes that this method represents a highly effective treatment option for herpes zoster pain, significantly improving pain control and patient comfort, thereby offering valuable implications for clinical practice in managing this challenging condition.
