Primary literature searches were performed in MEDLINE OVID, PubMed, EMBASE, the Cochrane Library), the Cochrane Central Register of Controlled Trials, the International HTA Database, CINAHL, and Web of Science to identify randomized controlled trials and quasi-experimental studies in animals utilizing sevoflurane or compound A. The primary outcomes included renal function as determined by blood urea nitrogen, serum creatinine, creatinine clearance, and urine volume. The secondary outcomes included the serum fluoride concentration and histopathological findings. A total of 2537 records were screened, and 21 randomized controlled trials and 9 quasi-experimental animal studies were identified. No associations between sevoflurane exposure and subsequent changes in renal function (blood urea nitrogen, serum creatinine or changes in urine volume) were noted. A similar effect on renal function was observed following compound A exposure, but urine volume was elevated following compound A exposure. In addition, the histopathological damage following compound A exposure was observed only at concentrations that are unachievable in clinical practice. Our review of evidence from animal models revealed that sevoflurane usage was not associated with changes in renal function tests or urine volume. Histopathologic changes after sevoflurane exposure were either nonexistent or minor. Studies on compound A did not reveal an alteration in renal function, although histopathological evidence of injury was present when compound A was administered at very high, unphysiologic concentrations. In light of the existing evidence, the initial concerns of sevoflurane-related nephrotoxicity based on animal studies that leads to minimum fresh gas flow recommendations are called into question.</p>","PeriodicalId":18559,"journal":{"name":"Medical Gas Research","volume":"15 2","pages":"254-265"},"PeriodicalIF":3.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11918462/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few reports on hyperbaric oxygen treatment for paroxysmal sympathetic hyperactivity at home and abroad, and the clinical experience is very limited. To understand the efficacy of hyperbaric oxygen treatment for paroxysmal sympathetic hyperactivity after brain injury, this retrospective study was conducted in the adult intensive care units of five medical centers in central China. Ninety-two patients with paroxysmal sympathetic hyperactivity syndrome after brain injury were selected from January 2021 to September 2023. Fifty-six patients treated with hyperbaric oxygen were included in the hyperbaric oxygen group, and 36 patients without hyperbaric oxygen treatment were included in the control group. Patients in the hyperbaric oxygen group received 3-5 courses of hyperbaric oxygen treatment, twice daily, once for 70 minutes, 10 days for 1 course of treatment. Compared with before hyperbaric oxygen treatment, the paroxysmal sympathetic hyperactivity symptoms of all patients were significantly relieved after three courses of hyperbaric oxygen treatment. Compared with those in the control group, patients in the hyperbaric oxygen group had higher Glasgow coma scale scores, lower paroxysmal sympathetic hyperactivity syndrome assessment measure scores, and shorter intensive care unit stays. In conclusion, the use of hyperbaric oxygen therapy as an assisted therapy can significantly alleviate the symptoms of patients with paroxysmal sympathetic hyperactivity, thereby providing new ideas for the treatment of paroxysmal sympathetic hyperactivity.</p>","PeriodicalId":18559,"journal":{"name":"Medical Gas Research","volume":"15 2","pages":"327-331"},"PeriodicalIF":3.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11918463/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143008294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are concerns that this may induce an imbalance in oxidation‒reduction processes, particularly in pediatric patients with compromised antioxidant defenses. This study aimed to evaluate the impact of varying intraoperative concentrations of oxygen inhalation on oxidative stress in children by analyzing plasma biomarkers, oxygenation indices, and the duration of surgery and oxygen inhalation. Forty-five children scheduled for laparoscopic pyeloplasty under general anesthesia were randomly assigned to three groups, each receiving different fractions of inspired oxygen during surgery: 30%, 50%, or 80%. The primary outcome was the plasma concentration of oxidative stress markers, and the other measurements included the surgical duration and duration of oxygen exposure. Thirty-five children completed the study, with 11 in the low group, 12 in the medium group and 12 in the high group. The levels of superoxide dismutase at immediately post-tracheal intubation, hydrogen peroxide at 1 hour post-intubation, and 8-isoprostane at immediately post-surgical procedure were significantly higher in the high group than in the low group. The S100B levels at immediately post-surgical procedure were higher than those at immediately post-tracheal intubation and 1 hour post-intubation within the low group. Therefore, we conclude that inhaling a high concentration of oxygen during laparoscopic pyeloplasty under general anesthesia, for a duration of less than 3 hours, does not significantly increase oxidative stress in pediatric patients.
