Objective To determine prevalence of delirium in critically-ill children and explore associated risk factors. Design Multi-institutional point-prevalence study. Setting Twenty-five pediatric critical care units in the United States, the Netherlands, New Zealand, Australia, and Saudi Arabia. Patients All children admitted to the pediatric critical care units on designated study days (n=994). Intervention Children were screened for delirium using the Cornell Assessment of Pediatric Delirium (CAPD) by the bedside nurse. Demographic and treatment-related variables were collected. Measurements and Main Results Primary study outcome measure was prevalence of delirium. In 159 children, a final determination of mental status could not be ascertained. Of the 835 remaining subjects, 25% screened positive for delirium, 13% were classified as comatose, and 62% were delirium-free and coma-free. Delirium prevalence rates varied significantly with reason for ICU admission, with highest delirium rates found in children admitted with an infectious or inflammatory disorder. For children who were in the PICU for 6 or more days, delirium prevalence rate was 38%. In a multivariate model, risk factors independently associated with development of delirium included age < 2 years, mechanical ventilation, benzodiazepines, narcotics, use of physical restraints, and exposure to vasopressors and anti-epileptics. Conclusions Delirium is a prevalent complication of critical illness in children, with identifiable risk factors. Further multi-institutional, longitudinal studies are required to investigate effect of delirium on long-term outcomes, and possible preventive and treatment measures. Universal delirium screening is practical and can be implemented in pediatric critical care units.
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.
Early clinical posttraumatic seizures occurred frequently in children with moderate to severe traumatic brain injury despite seizure prophylaxis with levetiracetam. Younger children and those with abusive head trauma were at increased risk of seizures. Further studies are needed to evaluate the efficacy of levetiracetam before it is routinely used for seizure prophylaxis in these children, particularly in young children and those who have suffered from abusive head trauma.
ObjectiveTo compare risk factors, clinical presentation, and outcomes after posterior circulation arterial ischemic stroke (PCAIS) and anterior circulation arterial ischemic stroke (ACAIS) in neonates and children.MethodsIn this international multicenter observational study including neonates and children up to 18 years of age with arterial ischemic stroke (AIS), we compared clinical and radiologic features according to stroke location.ResultsOf 2,768 AIS cases, 507 (18%) were located in the posterior circulation, 1,931 (70%) in the anterior circulation, and 330 (12%) involved both. PCAIS was less frequent in neonates compared to children (8.8% vs 22%, p < 0.001). Children with PCAIS were older than children with ACAIS (median age 7.8 [interquartile range (IQR) 3.1–14] vs 5.1 [IQR 1.5–12] years, p < 0.001), and more often presented with headache (54% vs 32%, p < 0.001) and a lower Pediatric NIH Stroke Scale score (4 [IQR 2–8] vs 8 [IQR 3–13], p = 0.001). Cervicocephalic artery dissections (CCAD) were more frequent (20% vs 8.5%, p < 0.001), while cardioembolic strokes were less frequent (19% vs 32%, p < 0.001) in PCAIS. Case fatality rates were equal in both groups (2.9%). PCAIS survivors had a better outcome (normal neurologic examination at hospital discharge in 29% vs 21%, p = 0.002) than ACAIS survivors, although this trend was only observed in children and not in neonates.ConclusionPCAIS is less common than ACAIS in both neonates and children. Children with PCAIS are older and have a higher rate of CCAD, lower clinical stroke severity, and better outcome than children with ACAIS.
Objective: We describe the risk factors for peri-procedural and spontaneous arterial ischemic stroke (AIS) in children with cardiac disease. Methods: We identified children with cardiac causes of AIS enrolled in the International Pediatric Stroke Study registry from January 2003 to July 2014. Isolated patent foramen ovale was excluded. Periprocedural AIS (those occurring during or within 72 hours of cardiac surgery, cardiac catheterization, or mechanical circulatory support) and spontaneous AIS that occurred outside of these time periods were compared. Results: We identified 672 patients with congenital or acquired cardiac disease as the primary risk factor for AIS. Among these, 177 patients (26%) had peri-procedural AIS and 495 patients (74%) had spontaneous AIS. Among non-neonates, spontaneous AIS occurred at older ages (median 4.2 years, interquartile range 0.97 to 12.4) compared with peri-procedural AIS (median 2.4 years, interquartile range 0.35 to 6.1, P < 0.001). About a third of patients in both groups had a systemic illness at the time of AIS. Patients who had spontaneous AIS were more likely to have a preceding thrombotic event (16 % versus 9 %, P ¼ 0.02) and to have a moderate or severe neurological deficit at discharge (67% versus 33%, P ¼ 0.01) compared to those with peri-procedural AIS.
