Mechanically ventilated children with 2009 pandemic influenza A/H1N1: results from the National Pediatric Intensive Care Registry in Japan.

Objective: To outline the characteristics, clinical course, and outcome of pediatric patients requiring mechanical ventilation with influenza A/H1N1 infection in Japan. Design: Prospective case registry analysis. Setting: Eleven pediatric or general intensive care units in Japan. Patients: Consecutive patients infected with A/H1N1, aged from 1 month to 16 yrs old admitted to the intensive care unit for mechanical ventilation between July 2009 and March 2010. Interventions: None. Measurements and Main Results: Eighty-one children, aged 6.3 [0.8–13.6] (median [interquartile range]) years, were enrolled. Seventy-four (91%) had mechanical ventilation with tracheal intubation. Median duration of mechanical ventilation was 4 days (range 0.04–87) and 18 patients (23%) required mechanical ventilation >7 days. Two patients (2%) required extracorporeal membrane oxygenation. The in-hospital mortality was 1%. Forty-one patients (50%) had at least one underlying chronic condition, including 31 with asthma. Associated clinical symptoms and diagnosis were as follows: acute respiratory distress syndrome (9%), asthma or bronchitis (37%), pneumonia (68%) with 8 (14%) having bacterial pneumonia, neurological symptoms (32%), myocarditis (2%), and rhabdomyolysis (1%). Therapeutic interventions include inotropic support (21%), methylprednisolone therapy (33%), and antimicrobial therapy (88%). Multivariate analysis revealed that inotropic support was the only statistically significant factor associated with mechanical ventilation for more than a week (odds ratio 5.5, 95% confidence interval 1.5–20.5, p = .005). Conclusions: The clinical presentations of pediatric patients requiring mechanical ventilation for A/H1N1 in Japan were diverse. In-hospital mortality of this population was remarkably low. Rapid access to medical facilities in combination with early administration of antiviral agents may have contributed to the low mortality in this population.

Proposal of a New Pediatric Sequential Organ Failure Assessment Score for Possible Validation

To the Editor:“Sepsis-3,” a new definition for sepsis and septic shock proposed in early 2016 (1), dramatically impacted on the critical care community around the world to change the concept of sepsis and septic shock from “systemic inflammatory response due to infection” to “acute and potentially l

Update on pediatric sepsis: a review

BackgroundSepsis is one of the leading causes of mortality among children worldwide. Unfortunately, however, reliable evidence was insufficient in pediatric sepsis and many aspects in clinical practice actually depend on expert consensus and some evidence in adult sepsis. More recent findings have given us deep insights into pediatric sepsis since the publication of the Surviving Sepsis Campaign guidelines 2012.Main textNew knowledge was added regarding the hemodynamic management and the timely use of antimicrobials. Quality improvement initiatives of pediatric “sepsis bundles” were reported to be successful in clinical outcomes by several centers. Moreover, a recently published global epidemiologic study (the SPROUT study) did not only reveal the demographics, therapeutic interventions, and prognostic outcomes but also elucidated the inappropriateness of the current definition of pediatric sepsis.ConclusionsWith these updated knowledge, the management of pediatric sepsis would be expected to make further progress. In addition, it is meaningful that the fundamental data on which future research should be based were established through the SPROUT study.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J‐SSCG 2016)

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J‐SSCG 2016), a Japanese‐specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 in Japanese. An English‐language version of these guidelines was created based on the contents of the original Japanese‐language version.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)

Background and purposeThe Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] https://doi.org/10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc.This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine.MethodsMembers of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (> 66.6%) majority vote of each of the 19 committee members.ResultsA total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs.ConclusionsBased on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.
