Antithrombin activity and central venous catheter-associated thrombosis in critically ill children at high risk of bleeding.

BACKGROUND: Normalization of antithrombin activity may prevent catheter-associated thrombosis in critically ill children at high risk of bleeding. OBJECTIVES: To characterize the temporal pattern of antithrombin activity, assess its association with catheter-associated thrombosis and clinically relevant bleeding, and evaluate its relationship with thrombin generation in these children. METHODS: In this prospective cohort study, critically ill children <18 years old at high risk of bleeding with central venous catheter were eligible. Antithrombin activity and thrombin generation were measured from platelet-poor plasma and after in vitro antithrombin supplementation. Systematic surveillance ultrasound was performed to diagnose thrombosis. Children were followed for bleeding. RESULTS: We enrolled 8 infants (median age: 0.2 years, IQR: 0.2, 0.3 years) and 72 older children (median age: 14.3 years, IQR: 9.1, 16.1 years). Mean antithrombin on the day of catheter insertion was 64 IU/dL (SD: 32 IU/dL) in infants and 83 IU/dL (SD: 35 IU/dL) in older children. Antithrombin normalized by the day of catheter removal. Thrombosis developed in 27 children, while 31 children bled. Thrombosis (regression coefficient: 0.008, 95% CI: -0.01, 0.03) and bleeding (regression coefficient: -0.0007, 95% CI: -0.02, 0.02) were not associated with antithrombin. Antithrombin was not correlated with in vivo change in endogenous thrombin potential (correlation coefficient: -0.07, 95% CI: -0.21, 0.08). In vitro supplementation reduced endogenous thrombin potential (correlation coefficient: -0.78; 95% CI: -0.95, -0.23). CONCLUSION: These findings may not support normalization of antithrombin activity to prevent catheter-associated thrombosis in critically ill children at high risk of bleeding.

Measuring Social Health Following Pediatric Critical Illness: A Scoping Review and Conceptual Framework.

OBJECTIVE: Social health is an important component of recovery following critical illness as modeled in the pediatric Post-Intensive Care Syndrome framework. We conducted a scoping review of studies measuring social outcomes (measurable components of social health) following pediatric critical illness and propose a conceptual framework of the social outcomes measured in these studies. DATA SOURCES: PubMed, EMBASE, PsycINFO, CINAHL, and the Cochrane Registry. STUDY SELECTION: We identified studies evaluating social outcomes in pediatric intensive care unit (PICU) survivors or their families from 1970-2017 as part of a broader scoping review of outcomes after pediatric critical illness. DATA EXTRACTION: We identified articles by dual review and dual-extracted study characteristics, instruments, and instrument validation and administration information. For instruments used in studies evaluating a social outcome, we collected instrument content and described it using qualitative methods adapted to a scoping review. DATA SYNTHESIS: Of 407 articles identified in the scoping review, 223 (55%) evaluated a social outcome. The majority were conducted in North America and the United Kingdom, with wide variation in methodology and population. Among these studies, 38 unique instruments were used to evaluate a social outcome. Specific social outcomes measured included individual (independence, attachment, empathy, social behaviors, social cognition, and social interest), environmental (community perceptions and environment), and network (activities and relationships) characteristics, together with school and family outcomes. While many instruments assessed more than one social outcome, no instrument evaluated all areas of social outcome. CONCLUSIONS: The full range of social outcomes reported following pediatric critical illness were not captured by any single instrument. The lack of a comprehensive instrument focused on social outcomes may contribute to under-appreciation of the importance of social outcomes and their under-representation in PICU outcomes research. A more comprehensive evaluation of social outcomes will improve understanding of overall recovery following pediatric critical illness.

Acute Care Pediatric Nurse Practitioner: The 2014 Practice Analysis.

INTRODUCTION: Practice research serves as the certification framework for validating advanced practice roles and updating national qualifying examinations. This national study describes the current practice of the acute care pediatric nurse practitioner (AC PNP) to inform an update of the Certified Pediatric Nurse Practitioner-Acute Care (CPNP-AC) examination content outline. METHOD: A descriptive analysis was performed of the responses of 319 pediatric nurse practitioners, practicing in an acute care role, who completed a practice survey in 2014. RESULTS: Respondents were primarily White women with a mean age of 40 years; 75% had been formally educated as AC PNPs, compared with 48% in 2009. Regional practice was most heavily concentrated in the Southeast (28%) and Midwest (27%). Most respondents (81%) practiced in urban areas. Respondents reported spending 75% of practice time in inpatient settings. The most frequently cited areas of practice were critical care (36%), followed by emergency department (9%) and subspecialty practices. DISCUSSION: This third analysis of AC PNP practice 10 years after initiation of the CPNP-AC certification examination demonstrates changes in clinical practice and educational preparation.

Pediatric Toxicology: Emerging Trends.

Poisoning represents one of the most common medical emergencies encountered worldwide and is especially problematic for children, who constitute the population that is most vulnerable and at risk for unintentional and preventable poisonings. The scope of toxic substances involved in poisoning is very broad, requiring health care providers to have an extensive knowledge of signs and symptoms of poisoning, as well as specific therapeutic interventions and antidotes. New synthetic and herbal substances have emerged that have resulted in significant poisoning morbidity and mortality in the pediatric population.

Guidelines for the determination of brain death in infants and children: an update of the 1987 Task Force recommendations.

OBJECTIVE: To review and revise the 1987 pediatric brain death guidelines. METHODS: Relevant literature was reviewed. Recommendations were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. CONCLUSIONS AND RECOMMENDATIONS: 1) Determination of brain death in term newborns, infants, and children is a clinical diagnosis based on the absence of neurologic function with a known irreversible cause of coma. Because of insufficient data in the literature, recommendations for preterm infants <37 wks gestational age are not included in this guideline. 2) Hypotension, hypothermia, and metabolic disturbances should be treated and corrected and medications that can interfere with the neurologic examination and apnea testing should be discontinued allowing for adequate clearance before proceeding with these evaluations. 3) Two examinations, including apnea testing with each examination separated by an observation period, are required. Examinations should be performed by different attending physicians. Apnea testing may be performed by the same physician. An observation period of 24 hrs for term newborns (37 wks gestational age) to 30 days of age and 12 hrs for infants and children (>30 days to 18 yrs) is recommended. The first examination determines the child has met the accepted neurologic examination criteria for brain death. The second examination confirms brain death based on an unchanged and irreversible condition. Assessment of neurologic function after cardiopulmonary resuscitation or other severe acute brain injuries should be deferred for ≥24 hrs if there are concerns or inconsistencies in the examination. 4) Apnea testing to support the diagnosis of brain death must be performed safely and requires documentation of an arterial Paco2 20 mm Hg above the baseline and ≥60 mm Hg with no respiratory effort during the testing period. If the apnea test cannot be safely completed, an ancillary study should be performed. 5) Ancillary studies (electroencephalogram and radionuclide cerebral blood flow) are not required to establish brain death and are not a substitute for the neurologic examination. Ancillary studies may be used to assist the clinician in making the diagnosis of brain death a) when components of the examination or apnea testing cannot be completed safely as a result of the underlying medical condition of the patient; b) if there is uncertainty about the results of the neurologic examination; c) if a medication effect may be present; or d) to reduce the interexamination observation period. When ancillary studies are used, a second clinical examination and apnea test should be performed and components that can be completed must remain consistent with brain death. In this instance, the observation interval may be shortened and the second neurologic examination and apnea test (or all components that are able to be completed safely) can be performed at any time thereafter. 6) Death is declared when these criteria are fulfilled.

World Federation of Pediatric Intensive and Critical Care Societies-its global agenda.

The World Federation of Pediatric Intensive and Critical Care Societies (WFPICCS) is an international body that brings together international expertise, experience, and influence to improve the outcomes of children suffering from life-threatening illness and injury. Its mission is educational, scientific, and charitable in nature. WFPICCS is committed to a global environment, in which all children have access to intensive and critical care of the highest standard. It exists to find ways of improving the care of critically ill children throughout the world, and making that knowledge available to those who care for such children. As in an ideal world all children should have access to state of the art critical care services, this is unlikely to happen anytime soon. Faced with this reality, the member societies of the WFPICCS will strive to develop the best model and provide the best care for critically ill and injured children worldwide. The challenge is to find the appropriate role that we need to (and can effectively) play in decreasing both unnecessary death and suffering for children. Clearly, we cannot achieve these goals on our own, hence WFPICCS visualizes close cooperation and collaboration with other agencies offering care to critically ill or injured children such as the World Health Organization, World Federation of Societies of Intensive and Critical Care Medicine, International Pediatric Associations, and regional organizations and programs to achieve our objectives. We feel that this document while imperfect is a good starting point and hope that it will stimulate more discussion to guide the agenda of the federation for years to come.

Responding to pediatric poisoning.

Make sure you know how to act quickly if a child ingests a toxic substance and what to teach parents to prevent accidental poisonings.

Pediatric poisonings: recognition, assessment, and management.

Poisoning represents one of the most common medical emergencies encountered in young children in the United States, and accounts for a significant proportion of emergency room visits for the adolescent population. Poisoning is a significant and persistent cause of morbidity and mortality in children and adolescents. The scope of toxic substances involved in poisoning is broad, and requires health care providers to have an extensive knowledge of signs and symptoms of poisoning and specific therapeutic interventions and antidotes. Most children who ingest poisons suffer no harm; however, health care providers must recognize, assess, and manage those exposures that are most likely to cause serious injury, illness, or death and initiate appropriate management to minimize the physical injury that may occur.

Nurse practitioners in pediatric critical care: results of a national survey.

The nurse practitioner in pediatric critical care is a distinct advanced practice nursing role that has seen a tremendous increase in development and implementation over the past 10 years. There is a paucity of literature on this unique and valuable role. A total of 74 nurse practitioners practicing in pediatric critical care were surveyed. Part I of the survey solicited descriptive information of the nurse practitioner including background, work environment, reporting structure, and salary. The respondents also identified their role responsibilities that included direct patient management, nursing and medical education, coordination of care, research, and consultation. Part II of the questionnaire addressed skill level and need for supervision for technical procedures and leadership activities. These respondents described expert or proficient skill levels for the majority of technical procedures (ie, lumbar puncture, central line placement) and leadership activities (ie, discharge planning, participation in medical rounds). This is the first published report to delineate the role of the nurse practitioner in pediatric critical care based on responses from a national survey.
