Objectives: With decreasing mortality in PICUs, a growing number of survivors experience long-lasting physical impairments. Early physical rehabilitation and mobilization during critical illness are safe and feasible, but little is known about the prevalence in PICUs. We aimed to evaluate the prevalence of rehabilitation for critically ill children and associated barriers. Design: National 2-day point prevalence study. Setting: Eighty-two PICUs in 65 hospitals across the United States. Patients: All patients admitted to a participating PICU for greater than or equal to 72 hours on each point prevalence day. Interventions: None. Measurements and Main Results: The primary outcome was prevalence of physical therapy– or occupational therapy–provided mobility on the study days. PICUs also prospectively collected timing of initial rehabilitation team consultation, clinical and patient mobility data, potential mobility–associated safety events, and barriers to mobility. The point prevalence of physical therapy– or occupational therapy–provided mobility during 1,769 patient-days was 35% and associated with older age (adjusted odds ratio for 13–17 vs < 3 yr, 2.1; 95% CI, 1.5–3.1) and male gender (adjusted odds ratio for females, 0.76; 95% CI, 0.61–0.95). Patients with higher baseline function (Pediatric Cerebral Performance Category, ≤ 2 vs > 2) less often had rehabilitation consultation within the first 72 hours (27% vs 38%; p < 0.001). Patients were completely immobile on 19% of patient-days. A potential safety event occurred in only 4% of 4,700 mobility sessions, most commonly a transient change in vital signs. Out-of-bed mobility was negatively associated with the presence of an endotracheal tube (adjusted odds ratio, 0.13; 95% CI, 0.1–0.2) and urinary catheter (adjusted odds ratio, 0.28; 95% CI, 0.1–0.6). Positive associations included family presence in children less than 3 years old (adjusted odds ratio, 4.55; 95% CI, 3.1–6.6). Conclusions: Younger children, females, and patients with higher baseline function less commonly receive rehabilitation in U.S. PICUs, and early rehabilitation consultation is infrequent. These findings highlight the need for systematic design of rehabilitation interventions for all critically ill children at risk of functional impairments.

Families identify overall health as a key outcome after pediatric critical illness. We conducted a planned secondary analysis of a scoping review to determine the methods, populations, and instruments used to evaluate overall health outcomes for both children and their families after critical illness. DESIGN:Planned Secondary Analysis of a Scoping Review. SETTING:We searched PubMed, EMBASE, PsycINFO, Cumulative Index of Nursing and Allied Health Literature, and the Cochrane Controlled Trials Registry databases from 1970 to 2017 to identify studies which measured postdischarge overall health of children who survived critical illness and their families. SUBJECTS:Articles reporting overall health outcomes after pediatric critical illness. INTERVENTIONS: None.MEASUREMENTS AND MAIN RESULTS: Among the 407 articles which measured outcomes following pediatric critical illness, 161 (40%) measured overall health. The overall health domain was most commonly measured in traumatic brain injury (44%) and the general PICU populations (16%). In total, there were 39 unique measures used to evaluate overall health. Across all subjects, seven measures accounted for 89% of instruments, with the Glasgow Outcome Scale (47%) and the Pediatric Overall Performance Category (17%) being most commonly used. Excluding studies targeting survivors of traumatic brain injury, Pediatric Overall Performance Category, Glasgow Outcome Scale, and the General Health Questionnaire were the most commonly used instruments. Patients were followed for a median 10.5 months (interquartile range, 4.5-21 mo). CONCLUSIONS:Overall health was commonly assessed post-PICU discharge, especially in the traumatic brain injury population, using a heterogenous array of measures. Evaluation and consensus are imperative to identify the most appropriate method to measure overall health with the goal of improving care efficacy and facilitating recovery across populations of critically ill children.

Summary Background/Aims Guidelines for referral of children to general anesthesia (GA) to complete MRI studies are lacking. We devised a pediatric procedural sedation guide to determine whether a pediatric procedural sedation guide would decrease serious adverse events and decrease failed sedations requiring rescheduling with GA. Methods We constructed a consensus-based sedation guide by combining a retrospective review of reasons for referral of children to GA (n = 221) with published risk factors associated with the inability to complete the MRI study with sedation. An interrupted time series analysis of 11 530 local sedation records from the Pediatric Sedation Research Consortium between July 2008 and March 2013, adjusted for case-mix differences in the pre- and postsedation guide cohorts, evaluated whether a sedation guide resulted in decreased severe adverse events (SAE) and failed sedation rates. Results A significant increase in referrals to GA following implementation of a sedation guide occurred (P < 0.001), and fewer children with an ASA-PS class ≥III were sedated using procedural sedation (P < 0.001). There was no decrease in SAE (P = 0.874) or in SAE plus airway obstruction with concurrent hypoxia (P = 0.435). There was no change in the percentage of failed sedations (P = 0.169). Conclusions More studies are needed to determine the impact of a sedation guide on pediatric procedural sedation services.

ObjectiveUsually only FDA-approved oxygenators are subject of studies by the international scientific community. The objective of this study is to evaluate two types of neonatal membrane oxygenators in terms of transmembrane pressure gradient, hemodynamic energy transmission and gaseous microemboli capture in simulated cardiopulmonary bypass systems.MethodsWe investigated the Braile Infant 1500 (Braile Biomédica, São José do Rio Preto, Brazil), an oxygenator commonly used in Brazilian operating rooms, and compared it to the Dideco Kids D100 (Sorin Group, Arvada, CO, USA), that is an FDA-approved and widely used model in the USA. Cardiopulmonary bypass circuits were primed with lactated Ringer's solution and packed red blood cells (Hematocrit 40%). Trials were conducted at flow rates of 500 ml/min and 700 ml/min at 35ºC and 25ºC. Real-time pressure and flow data were recorded using a custom-based data acquisition system. For gaseous microemboli testing, 5cc of air were manually injected into the venous line. Gaseous microemboli were recorded using the Emboli Detection and Classification Quantifier.ResultsBraile Infant 1500 had a lower pressure drop (P<0.01) and a higher total hemodynamic energy delivered to the pseudopatient (P<0.01). However, there was a higher raw number of gaseous microemboli seen prior to oxygenator at lower temperatures with the Braile oxygenator compared to the Kids D100 (P<0.01).ConclusionBraile Infant 1500 oxygenator had a better hemodynamic performance compared to the Dideco Kids D100 oxygenator. Braile had more gaseous microemboli detected at the pre-oxygenator site under hypothermia, but delivered a smaller percentage of air emboli to the pseudopatient than the Dideco oxygenator.

Most reported cases of serotonin syndrome involve either a selective serotonin reuptake inhibitor (SSRI) or monoamine oxidase inhibitors (MAOI) and at least 1 other serotonergic medication or exposure to a single serotonin-augmenting drug. This case report describes serotonin syndrome occurring in association with the concomitant use of the antibiotic linezolid and opioids, specifically methadone, in a pediatric intensive care unit patient. The patient developed hyperpyrexia, muscle rigidity, clonus, and multiorgan dysfunction within 48 hours of receiving linezolid while concurrently on methadone. This drug-drug interaction is a rare cause of serotonin syndrome that has only been described 1 other time in the adult literature. This report raises awareness of this rare but serious and potentially lethal complication of serotonin syndrome associated with concomitant linezolid and opioid use. Timely consideration of the diagnosis in the setting of hyperpyrexia can facilitate prompt initiation of targeted therapies to prevent sequela.
