AimContinuous renal replacement therapy (CRRT) with a cytokine‐adsorbing hemofilter (CAH) is effective in the treatment of sepsis. Two filter types, namely polymethyl methacrylate (PMMA) and surface‐treated AN69 (AN69ST) hemofilters, have been successfully used for CRRT, but no direct comparisons have been published to date. This study compared the efficacy, as measured by 28‐day survival rates, of PMMA and AN69ST hemofilters in patients receiving CAH‐CRRT.MethodsThis retrospective observational study reviewed the medical records of 142 patients who received CAH‐CRRT between November 2013 and February 2015.ResultsThe 28‐day survival rates were higher in the AN69ST group than in the PMMA group for patients with or without sepsis (all patients, 79.4% versus 54.1%; patients with sepsis, 77.3% versus 50.0%; patients without sepsis, 83.3% versus 57.5%; P < 0.05). No significant differences were observed regarding 28‐day survival rates of patients with or without sepsis (AN69ST, 77.3% versus 83.3%; P = 0.51; PMMA, 50.0% versus 57.5%; P = 0.61) using the same hemofilter.ConclusionThe AN69ST hemofilter could be more effective than PMMA hemofilters for improving the survival outcomes of patients with or without sepsis.
Severe coronavirus disease (COVID-19) can induce serious complications, including acute respiratory distress syndrome, septic shock, and acute kidney injury. However, few reports have associated COVID-19 with pancreatitis. We herein report the case of a 55-year-old patient who developed acute pancreatitis associated with severe COVID-19 pneumonia and was successfully treated with veno-venous extracorporeal membrane oxygenation (ECMO). Elevated pancreatic enzymes levels and computed tomography findings led to the diagnosis of acute pancreatitis due to COVID-19. Although we found that severe COVID-19 pneumonia can lead to pancreatitis, the underlying pathophysiology remains unknown.
Background The joint committee of the Japanese Society of Intensive Care Medicine/Japanese Respiratory Society/Japanese Society of Respiratory Care Medicine on ARDS Clinical Practice Guideline has created and released the ARDS Clinical Practice Guideline 2021. Methods The 2016 edition of the Clinical Practice Guideline covered clinical questions (CQs) that targeted only adults, but the present guideline includes 15 CQs for children in addition to 46 CQs for adults. As with the previous edition, we used a systematic review method with the Grading of Recommendations Assessment Development and Evaluation (GRADE) system as well as a degree of recommendation determination method. We also conducted systematic reviews that used meta-analyses of diagnostic accuracy and network meta-analyses as a new method. Results Recommendations for adult patients with ARDS are described: we suggest against using serum C-reactive protein and procalcitonin levels to identify bacterial pneumonia as the underlying disease (GRADE 2D); we recommend limiting tidal volume to 4–8 mL/kg for mechanical ventilation (GRADE 1D); we recommend against managements targeting an excessively low SpO2 (PaO2) (GRADE 2D); we suggest against using transpulmonary pressure as a routine basis in positive end-expiratory pressure settings (GRADE 2B); we suggest implementing extracorporeal membrane oxygenation for those with severe ARDS (GRADE 2B); we suggest against using high-dose steroids (GRADE 2C); and we recommend using low-dose steroids (GRADE 1B). The recommendations for pediatric patients with ARDS are as follows: we suggest against using non-invasive respiratory support (non-invasive positive pressure ventilation/high-flow nasal cannula oxygen therapy) (GRADE 2D), we suggest placing pediatric patients with moderate ARDS in the prone position (GRADE 2D), we suggest against routinely implementing NO inhalation therapy (GRADE 2C), and we suggest against implementing daily sedation interruption for pediatric patients with respiratory failure (GRADE 2D). Conclusions This article is a translated summary of the full version of the ARDS Clinical Practice Guideline 2021 published in Japanese (URL: https://www.jsicm.org/publication/guideline.html). The original text, which was written for Japanese healthcare professionals, may include different perspectives from healthcare professionals of other countries.
Purpose To validate our previously designed transcatheter arterial embolization (TAE) technique for bilateral iliac arteries in unstable pelvic fractures, which is designed to also prevent gluteal necrosis and avoid vasopressors. Methods We retrospectively analyzed the data of patients with pelvic fractures who underwent our new TAE procedure to determine the incidence of subsequent gluteal necrosis. We also compared certain variables between patients who underwent TAE before 2005 using a different technique and developed gluteal necrosis and patients who underwent TAE in 2005 and onward using our technique. Gluteal necrosis was confirmed by a radiologist based on imaging findings. Results Seventy patients with pelvic fractures who underwent our TAE technique met the inclusion criteria (bilateral iliac arterial embolization and no embolic agent other than a gelatin sponge). Patients’ median age was 47.5 years, 33 were male, and 92.9% (65/70) had unstable fractures. Sixty-eight patients had severe multiple trauma. No patients developed gluteal necrosis following our TAE procedure and the overall survival rate was 82.9% (58/70). We found no statistically significant difference in procedure time between the previous and new technique, although the new procedure tended to be shorter. Furthermore, overall survival did not significantly differ between the groups. Multiple regression analysis revealed that TAE procedure time and external pelvic fracture fixation were independently related to gluteal necrosis. Conclusions Our non-selective bilateral iliac arterial embolization procedure involves arresting shock quickly, resulting in no post-procedure gluteal necrosis. The procedure involves cutting the gelatin sponge rather than “pumping” and avoids the use of vasopressors.
