A meta-analysis was conducted to evaluate the efficacy and safety of enteral nutrition in the prone position in critically ill ventilated patients.MethodsBy searching databases such as PubMed, Embase, Cochrane Library, Web of Science, Cumulative Index of Nursing and Allied Health Literature, and WanFang Data, the relevant literature was retrieved from their inception to 24 December 2024. The Newcastle-Ottawa Scale was used to evaluate article quality. Egger's test was used to check for publication bias, and Review Manager 5.4 was used to conduct the analyses.ResultsAmong 81 publications, five studies with a total sample size of 319 were included in this study. Enteral nutrition in the prone position, compared with that in the supine position, was associated with a lower energy achievement rate (mean difference: -0.88; 95% confidence interval: -1.83 to 0.06; P < 0.00001), no significant difference in mortality (odds ratio: 1.11; 95% confidence interval: 0.65 to 1.88; P = 0.7), a greater incidence of ventilator-associated pneumonia (odds ratio: 2.11; 95% confidence interval: 1.12 to 3.96; P = 0.02), more frequent vomiting (odds ratio: 2.38; 95% confidence interval: 1.61 to 3.50; P < 0.0001), a greater gastric residual volume (odds ratio: 2.72; 95% confidence interval: 1.47 to 5.03; P = 0.001), and increased interruptions in enteral nutrition (odds ratio: 4.75; 95% confidence interval: 2.22 to 10.17; P < 0.0001). The Egger's test suggested no significant publication bias in the meta-analysis of mortality, gastric residual volume, adequate enteral nutrition achievement, and ventilator-associated pneumonia.ConclusionA greater gastric residual volume, more frequent vomiting, and greater incidences of ventilator-associated pneumonia and enteral feeding interruptions are linked to enteral nutrition during prone ventilation. There was no statistically significant difference in mortality between the prone and supine positions. However, the prone position showed a slight trend toward reducing energy achievement rates, although this difference was not statistically significant.<b>Trial registration number:</b> PROSPERO CRD: 42023441409.</p>","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 4","pages":"3000605251322358"},"PeriodicalIF":1.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pro-inflammatory cytokines, including interleukin-6 (IL-6), have significant effects on cardiac conduction. Atrial or ventricular arrhythmias occurring while infected results in a doubling of mortality. Tocilizumab, a monoclonal antibody that blocks the IL-6 receptor, is associated with improved mortality and is believed to be related to immune modulation of the COVID-19-related hyperinflammatory state.MethodsA single-center retrospective review of all patients with severe COVID-19, defined as admission to an intensive care unit or requirement of respiratory or circulatory support, from March 2020 through March 2022, was conducted. Patients who received or did not receive tocilizumab were grouped into the treatment and control groups, respectively.ResultsFour hundred seventy-three patients were reviewed and 400 met the criteria for inclusion in our study. There were 305 patients (age, 63 ± 13 years, 58% male) in the control group and 95 (age, 57 ± 15 years, 51% male) in the treatment group. In-hospital mortality was greatly reduced with tocilizumab compared with controls (44.2% vs 85.9%, p < 0.001) and new-onset atrial fibrillation (AF) showed a statistically significant reduction (17.8% vs 29.5%, p = 0.019). New-onset wall motion abnormalities, potentially related to myocarditis or acute coronary syndrome, also trended toward significance with tocilizumab (7.7% vs 15.7%, p = 0.10). Deep vein thrombosis, pulmonary embolism, stroke, and sustained ventricular arrhythmias did not meet statistical significance.ConclusionAs expected, tocilizumab did show significant improvement in mortality. Tocilizumab also showed a significant reduction of new-onset AF.
