However, UPNB is often understood as an unintended but potentially critical complication of interscalene brachial plexus block (ISB) rather than a planned procedure. Therefore, we review the existing data on the effectiveness of UPNBs in enhancing respiratory functioning. We searched Medline, EMBASE, Web of Science, and Google Scholar for clinical data related to UPNBs up until May 2025. The primary outcome of this review was to determine the impact of UPNB in minimizing dyspnea or desaturation among patients. Secondary outcomes included UPNB's effectiveness in reducing the intensity and frequency of hiccups and enhancing pulmonary function testing (PFT) and arterial blood gas (ABG) values. Twenty-six studies met the inclusion criteria. The findings show that UPNB does not induce or worsen dyspnea among patients. The injection produced better saturation, with some studies reporting 99% and 96% - 100% oxygen saturation. Besides, phrenic nerve block injection is vital in reducing diaphragmatic pain. Patients who exhibited intractable or persistent hiccups had their frequency and severity reduced or vanished after the nerve block injection. Our findings show that UPNB positively affected ABG samples (fair PaO2, PaCO2, and arterial pH) and spirometry/PFT values (fair FEV1, FVC, and PEF). UPNB enhanced oxygen saturation, reduced intractable hiccups, and preserved PFT and ABG values. Additionally, UPNB did not induce or worsen dyspnea and desaturation. Nevertheless, more clinical trials are needed to confirm these findings.</p>","PeriodicalId":101360,"journal":{"name":"Anesthesia and pain medicine","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This disabling pain can persist for years, severely diminishing the quality of life of the affected individuals. The treatment options available for neuropathic pain at present have limited efficacy. Moreover, the adverse effects associated with these options restrict their application. The exact etiological mechanisms underlying the pathogenesis of neuropathic pain remain unclear. However, neuroinflammatory processes mediated by the immune system play significant roles in the initiation and progression of neuropathic pain in various models. The nucleotide-binding domain and leucine-rich repeat pyrin-containing protein-3 (NLRP3) inflammasome, a pivotal element of the innate immune system, plays an indispensable role in the pathophysiological mechanisms of central and peripheral neuropathic pain. However, the precise mechanisms facilitating its activation in disparate neuropathic pain conditions remain to be elucidated. Gaining insights into the regulatory mechanisms affecting NLRP3 inflammasome activation in diverse neuropathic pain-associated disorders will aid in developing novel therapeutic avenues. Therefore, this review summarizes the current knowledge on the role of the NLRP3 inflammasome in the pathophysiology of several neuropathic pain-related conditions, such as diabetic neuropathic pain, chemotherapy-induced neuropathic pain, peripheral nerve compression, central nervous system neuropathic pain, radiculopathy, and morphine analgesic tolerance. In addition, this review also discusses the possible use of this inflammasome as a therapeutic target to alleviate the pain-related symptoms of these diseases.</p>","PeriodicalId":101360,"journal":{"name":"Anesthesia and pain medicine","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
