Objectives We elucidate to investigate the prevalence of and factors associated with the use of physical restraints among critically ill or injured children in PICUs. Design This was a multicenter, longitudinal point prevalence study. Setting We included 26 PICUs in Japan. Patients Included children were 1 month to 10 years old. We screened all admitted patients in the PICUs on three study dates (in March, June, and September 2019). Intervention None. Measurements and main results We collected prevalence and demographic characteristics of critically ill or injured children with physical restraints, as well as details of physical restraints, including indications and treatments provided. A total of 398 children were screened in the participating PICUs on the three data collection dates. The prevalence of children with physical restraints was 53% (211/398). Wrist restraint bands were the most frequently used means (55%, 117/211) for potential contingent events. The adjusted odds of using physical restraint in patients 1-2 years old was 2.3 (95% CI, 1.3-4.0) compared with children less than 1 year old. When looking at the individual hospital effect, units without a prespecified practice policy for physical restraints management or those with more than 10 beds were more likely to use physical restraints. Conclusions The prevalence of physical restraints in critically ill or injured children was high, and significant variation was observed among PICUs. Our study findings suggested that patient age, unit size, and practice policy of physical restraint could be associated with more frequent use of physical restraints.

No imaging modality can be used to evaluate Fontan-associated liver disease (FALD). We retrospectively reviewed hepatic gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) characteristics of patients within 1 year post-Fontan procedure, and we evaluated the association between hepatic imaging abnormalities and clinical parameters, including follow-up cardiac catheterization and laboratory test findings. The EOB-MR images were graded, based on the extent of the decreased enhancement, as “normal” (Grade 1), “segmental” (Grade 2), “regional” (Grade 3), and “diffuse” (Grade 4). We enrolled 37 patients (mean age, 3.5 ± 1.0 years): 9 patients had Grade 1 or 2; 14 patients, Grade 3; and 14 patients, Grade 4. EOB-MRI revealed characteristic reticular or mosaic patterns of diminished enhancement (i.e. “frog spawn” appearance). Ultrasonography did not detect diminished enhancement or “frog spawn” appearance. A trend existed toward increased grade severity in imaging with increased central venous pressure, pulmonary vascular resistance, and gamma-glutamyltransferase levels. Noninvasive EOB-MRI revealed the characteristic pattern of diminished enhancement, which was correlated with certain clinical parameters indicative of Fontan physiology and liver dysfunction. Early-stage FALD may occur soon after the Fontan procedure and is associated with increased pressure in the inferior vena cava and hepatic veins.

IMPORTANCE: Few studies with sufficient statistical power have shown the association of the z score of the coronary arterial internal diameter with coronary events (CE) in patients with Kawasaki disease (KD) with coronary artery aneurysms (CAA). OBJECTIVE: To clarify the association of the z score with time-dependent CE occurrence in patients with KD with CAA. DESIGN, SETTING, AND PARTICIPANTS: This multicenter, collaborative retrospective cohort study of 44 participating institutions included 1006 patients with KD younger than 19 years who received a coronary angiography between 1992 and 2011. MAIN OUTCOMES AND MEASURES: The time-dependent occurrence of CE, including thrombosis, stenosis, obstruction, acute ischemic events, and coronary interventions, was analyzed for small (z score

Background Several coronary artery Z score models have been developed. However, a Z score model derived by the lambda-mu-sigma (LMS) method has not been established. Methods Echocardiographic measurements of the proximal right coronary artery, left main coronary artery, proximal left anterior descending coronary artery, and proximal left circumflex artery were prospectively collected in 3,851 healthy children ≤18 years of age and divided into developmental and validation data sets. In the developmental data set, smooth curves were fitted for each coronary artery using linear, logarithmic, square-root, and LMS methods for both sexes. The relative goodness of fit of these models was compared using the Bayesian information criterion. The best-fitting model was tested for reproducibility using the validation data set. The goodness of fit of the selected model was visually compared with that of the previously reported regression models using a Q-Q plot. Results Because the internal diameter of each coronary artery was not similar between sexes, sex-specific Z score models were developed. The LMS model with body surface area as the independent variable showed the best goodness of fit; therefore, the internal diameter of each coronary artery was transformed into a sex-specific Z score on the basis of body surface area using the LMS method. In the validation data set, a Q-Q plot of each model indicated that the distribution of Z scores in the LMS models was closer to the normal distribution compared with previously reported regression models. Finally, the final models for each coronary artery in both sexes were developed using the developmental and validation data sets. A Microsoft Excel–based Z score calculator was also created, which is freely available online (http://raise.umin.jp/zsp/calculator/). Conclusions Novel LMS models with which to estimate the sex-specific Z score of each internal coronary artery diameter were generated and validated using a large pediatric population.

Objectives To determine the most effective first-line rescue therapy for intravenous immunoglobulin (IVIG) nonresponders, using IVIG, prednisolone, or both, to prevent coronary artery abnormalities (CAAs). Study design We retrospectively reviewed the clinical records of 359 consecutive patients with Kawasaki disease who failed to respond to initial IVIG. Results CAAs up to 1 month after treatment were less common in the IVIG+prednisolone group (15.9%) than in the IVIG group (28.7%, P = .005) and the prednisolone group (30.6%, P = .01). The IVIG+prednisolone group had significantly lower risks of failing to respond to first-line rescue therapy (aOR 0.16, 95% CI 0.09-0.31), CAAs up to 1 month (aOR 0.46, 95% CI 0.27-0.90), and CAAs at 1 month (aOR 0.40, 95% CI 0.18-0.91) than the IVIG group. In the prednisolone and IVIG+prednisolone groups, risk score, day of illness at first-line rescue therapy, prednisolone monotherapy, and resistance to first-line rescue therapy were independent risk factors for CAA. Sex and resistance to first-line rescue therapy were independent risk factors in the IVIG group. Conclusions IVIG+prednisolone may be superior to IVIG or prednisolone as first-line rescue therapy in the treatment of IVIG nonresponders. To establish the efficacy of rescue therapy with IVIG+prednisolone following nonresponse to initial IVIG, a prospective randomized trial is warranted.

we previously developed a new risk score to predict intravenous immunoglobulin (IVIG) resistance in Kawasaki disease. However, the IVIG dosage used in that study (1 g/kg/d for 2 consecutive days) differs from the single infusion of 2 g/kg recommended in the United States and elsewhere. Our aim was to assess the validity and applicability of our risk score in patients treated with a single infusion.we used a database of 1626 patients with Kawasaki disease given initial IVIG treatment at a dose of 1 g/kg/d for 2 consecutive days (n = 990; IVIG- 1 g/kg × 2) or 2 g/kg/d for 1 day (n = 636; IVIG- 2 g/kg × 1) across 17 hospitals in Japan. Patients received the total IVIG dose within 36 hours in IVIG- 1 g/kg × 2 and 24 hours in IVIG- 2 g/kg × 1. We stratified the patients according to a risk scoring system developed to predict IVIG unresponsiveness, based on scores of ≥ 5 points. We compared the accuracy of prediction between the 2 groups using receiver operating characteristic analysis.baseline characteristics and clinical outcomes were similar between both groups. The areas under the receiver operating characteristic curve in IVIG- 2 g/kg × 1 were similar to those of IVIG- 1 g/kg × 2. Using a cut-off risk score of ≥ 5 points, we could identify IVIG resistance in terms of coronary artery abnormalities within 1 month and coronary artery abnormalities at 1 month with equivalent sensitivity and specificity in both groups.our risk score can be used to predict IVIG unresponsiveness to a regimen based on a single infusion of 2 g/kg IVIG.
