Chemical-biological terrorism and its impact on children

Emergency Triage of Highly Infectious Diseases and Bioterrorism

Emergency medical services are a key element in health systems for the evaluation and treatment of patients exposed to highly infectious diseases or bioterrorism agents. Triage and early identification at any point of care can have a significant impact on the prevention and management of these diseases. This chapter reviews triage practices, including early isolation and decontamination, of highly infectious diseases and bioterrorism agents at different health system levels.

Provision of Care for Critically Ill Children in Disasters

Children are affected by all types of disasters disproportionately compared with adults. Despite this, planning and readiness to care for children in disasters is suboptimal locally, nationally, and internationally. These planning gaps increase the likelihood that a disaster will have a greater negative impact on children when compared with adults. New voluntary regional coalitions have been developed to fill this gap. Some are pediatric focused or have pediatrics well integrated into the greater coalition. This article discusses key points of pediatric disaster planning, specific vulnerabilities, and the care of children in general and in specific disaster situations.

Planning for disasters involving children in Australia: A practical guide

Children comprise 19% of the Australian population. Children are at risk of higher morbidity and mortality in disaster events than adults; however, there is a paucity of paediatric-specific disaster preparedness in Australia. Paediatric disaster plans should be developed, tested and renewed regularly. Plans need to address unaccompanied and unidentified children, medical and psychosocial needs and family reunification. Specific management is required for chemical, biological and radiological events.

Disaster preparedness, pediatric considerations in primary blast injury, chemical, and biological terrorism

Both domestic and foreign terror incidents are an unfortunate outgrowth of our modern times from the Oklahoma City bombings, Sarin gas attacks in Japan, the Madrid train bombing, anthrax spores in the mail, to the World Trade Center on September 11(th), 2001. The modalities used to perpetrate these terrorist acts range from conventional weapons to high explosives, chemical weapons, and biological weapons all of which have been used in the recent past. While these weapons platforms can cause significant injury requiring critical care the mechanism of injury, pathophysiology and treatment of these injuries are unfamiliar to many critical care providers. Additionally the pediatric population is particularly vulnerable to these types of attacks. In the event of a mass casualty incident both adult and pediatric critical care practitioners will likely be called upon to care for children and adults alike. We will review the presentation, pathophysiology, and treatment of victims of blast injury, chemical weapons, and biological weapons. The focus will be on those injuries not commonly encountered in critical care practice, primary blast injuries, category A pathogens likely to be used in terrorist incidents, and chemical weapons including nerve agents, vesicants, pulmonary agents, cyanide, and riot control agents with special attention paid to pediatric specific considerations.

Respiratory protection during simulated emergency pediatric life support: a randomized, controlled, crossover study

INTRODUCTION

Emergency pediatric life support (EPLS) of children infected with transmissible respiratory diseases requires adequate respiratory protection for medical first responders. Conventional air-purifying respirators (APR) and modern loose-fitting powered air-purifying respirator-hoods (PAPR-hood) may have a different impact during pediatric resuscitation and therefore require evaluation.

OBJECTIVE

This study investigated the influence of APRs and PAPR-hoods during simulated pediatric cardiopulmonary resuscitation.

METHODS

Study design was a randomized, controlled, crossover study. Sixteen paramedics carried out a standardized EPLS scenario inside an ambulance, either unprotected (control) or wearing a conventional APR or a PAPR-hood. Treatment times and wearer comfort were determined and compared.

RESULTS

All paramedics completed the treatment objectives of the study arms without adverse events. Study subjects reported that communication, dexterity and mobility were significantly better in the APR group, whereas the heat-build-up was significantly less in the PAPR-hood group. Treatment times compared to the control group did not significantly differ for the APR group but did with the PAPR-hood group (261±12 seconds for the controls, 275±9 seconds for the conventional APR and 286±13 seconds for the PAPR-hood group, P < .05.

CONCLUSIONS

APRs showed a trend to better treatment times compared to PAPR-hoods during simulated pediatric cardiopulmonary resuscitation. Study participants rated mobility, ease of communication and dexterity with the tight-fitting APR system significantly better compared to the loose-fitting PAPR-hood.

Disaster Preparedness: Hospital Decontamination and the Pediatric Patient— Guidelines for Hospitals and Emergency Planners

In recent years, attention has been given to disaster preparedness for first responders and first receivers (hospitals). One such focus involves the decontamination of individuals who have fallen victim to a chemical agent from an attack or an accident involving hazardous materials. Children often are overlooked in disaster planning. Children are vulnerable and have specific medical and psychological requirements. There is a need to develop specific protocols to address pediatric patients who require decontamination at the entrance of hospital emergency departments. Currently, there are no published resources that meet this need. An expert panel convened by the New York City Department of Health and Mental Hygiene developed policies and procedures for the decontamination of pediatric patients.The panel was comprised of experts from a variety of medical and psychosocial areas.Using an iterative process, the panel created guidelines that were approved by the stakeholders and are presented in this paper.These guidelines must be utilized, studied, and modified to increase the likelihood that they will work during an emergency situation.

Principles of Disaster Planning for the Pediatric Population

Unique physiological, developmental, and psychological attributes of children make them one of the more vulnerable populations during mass-casualty incidents. Because of their distinctive vulnerabilities, it is crucial that pediatric needs are incorporated into every stage of disaster planning. Individuals, families, and communities can help mitigate the effects of disasters on pediatric populations through ongoing awareness and preventive practices. Mitigation efforts also can be achieved through education and training of the healthcare workforce. Preparedness activities include gaining Emergency Medical Services for Children Pediatric Facility Recognition, conducting pediatric disaster drills, improving pediatric surge capacity, and ensuring that the needs children are incorporated into all levels of disaster plans. Pediatric response can be improved in a number of ways, including: (1) enhanced pediatric disaster expertise; (2) altered decontamination protocols that reflect pediatric needs; and (3) minimized parent-child separation. Recovery efforts at the pediatric level include promoting specific mental health therapies for children and incorporating children into disaster relief and recovery efforts. Improving pediatric emergency care needs should be at the forefront of every disaster planner's agenda.

Preparedness lessons from modern disasters and wars

Disasters come in all shapes and forms, and in varying magnitudes and intensities. Nevertheless, they offer many of the same lessons for critical care practitioners and responders. Among these, the most important is that well thought out risk assessment and focused planning are vital. Such assessment and planning require proper training for providers to recognize and treat injury from disaster, while maintaining safety for themselves and others. This article discusses risk assessment and planning in the context of disasters. The article also elaborates on the progress toward the creation of portable, credible, sustainable, and sophisticated critical care outside the walls of an intensive care unit. Finally, the article summarizes yields from military-civilian collaboration in disaster planning and response.

Impact of an educational intervention on residents' knowledge of pediatric disaster medicine

BACKGROUND

Globally, natural and created events have underscored the vulnerability of children in disasters. There is an unmet need for a standardized pediatric disaster medicine (PDM) curriculum.

OBJECTIVE

To create and implement a PDM course, measure course efficacy, and assess residents' attitudes toward and experience in disaster medicine.

DESIGN/METHODS

An educational intervention was conducted for pediatric and emergency medicine residents at a tertiary care teaching hospital. Participants completed a precourse survey of PDM attitudes and experience. Paired t tests were used to compare pretest, immediate posttest, and delayed posttest scores. Test performance was assessed by resident type and postgraduate year. A postcourse survey gauged reaction to the course and interest in further PDM training.

RESULTS

Among the participants, 11 residents (9.4%) have treated disaster victims, and 5 (4.3%) had formal disaster medicine education. Most (83%) felt PDM is an important part of their training. Seventy-five eligible residents (64.6%) completed the intervention. Pairwise comparison of scores showed a mean improvement in scores of 24.5% immediately after taking the course (95% confidence interval, 22.9%-30.1%; P < 0.001). Two months later, residents scored a mean of 69.0% for the delayed posttest, with a retained improvement in scores (18.3%; 95% confidence interval, 14.3%-22.3%; P < 0.001). Residents preferred future PDM exercises to additional didactic training (72.0% vs. 32.7%; P < 0.001%).

CONCLUSIONS

Residents who complete this curriculum increase their knowledge of PDM with moderate retention of information. Most residents lack PDM training, believe it is important, and request disaster-training exercises.

Pediatric disaster preparedness: best planning for the worst-case scenario

Natural and man-made disasters are unpredictable but certainly will include children as victims. Increasingly, knowledge of pediatric disaster preparedness is required of emergency and primary care practitioners. A complete pediatric disaster plan comprises the following elements: appropriate personnel and equipment, disaster- and venue-specific training, and family preparedness. Disaster preparedness exercises are crucial for training plan implementation and response evaluation. Exercise content depends on local hazard vulnerabilities and learner training needs. Postexercise evaluations follow a stepwise process that culminates in improved disaster plans. This article will review disaster planning and the design, implementation, and evaluation of pediatric disaster exercises.

[Hospital emergency department preparedness for NBC mass casualties]

Hospital emergency department preparedness for mass-casualty incidents involving nuclear, biological or chemical (NBC) threats relies on close cooperation between hospital and pre-hospital emergency staff. It is essential that the hospital is immediately secured from unauthorized intrusion in order to avoid contamination of the hospital area and staff. The strategy of the pre-hospital emergency staff to avoid the unnecessary spread of contaminated material involves thorough decontamination of exposed persons near the site of the incident and coordinated transport to the primary care hospitals after decontamination. However, uncoordinated access of contaminated victims requires emergency decontamination by hospital staff. Thus, hospital staff must be prepared to provide in-hospital decontamination. Coordinated admission of contaminated patients into the NBC primary care hospital relies on a thorough decontamination by pre-hospital emergency staff at a decontamination site installed outside the hospital. Screening of patients is performed by hospital staff with special expertise in emergency medicine. Following admission, each patient is assigned to a team of specialists. Pre-hospital patient documentation is switched to inhospital documentation after admission using machine-readable electronic admission numbers.

Pandemic influenza planning in nursing homes: are we prepared?

Avian influenza or Influenza A (H5N1) is caused by a viral strain that occurs naturally in wild birds, but to which humans are immunologically naïve. If an influenza pandemic occurs, it is expected to have dire consequences, including millions of deaths, social disruption, and enormous economic consequences. The Department of Health and Human Resources plan, released in November 2005, clearly affirms the threat of a pandemic. Anticipating a disruption in many factions of society, every segment of the healthcare industry, including nursing homes, will be affected and will need to be self-sufficient. Disruption of vaccine distribution during the seasonal influenza vaccine shortage during the 2004/05 influenza season is but one example of erratic emergency planning. Nursing homes will have to make vital decisions and provide care to older adults who will not be on the initial priority list for vaccine. At the same time, nursing homes will face an anticipated shortage of antiviral medications and be expected to provide surge capacity for overwhelmed hospitals. This article provides an overview of current recommendations for pandemic preparedness and the potential effect of a pandemic on the nursing home industry. It highlights the need for collaborative planning and dialogue between nursing homes and various stakeholders already heavily invested in pandemic preparedness.

Antidotes for nerve agent poisoning: should we differentiate children from adults?

PURPOSE OF REVIEW

Chemical terrorism presents a threat to the civilian population, including children. Nerve agent antidotes are available in prepackaged autoinjectors that can be delivered rapidly following an exposure. The published evidence on the use of nerve agent antidotes consists of case reports, extrapolation from pediatric organophosphate poisonings, and expert opinion. This review examines the evidence supporting the use of nerve agent antidotes in children.

RECENT FINDINGS

The use of adult formulated atropine and pralidoxime autoinjectors will deliver doses above current recommendations for infants and children. Data demonstrate, however, that atropine overdose is generally well tolerated in young children. Children symptomatic of nerve agent poisoning will likely need both supraphysiologic doses and frequent re-dosing of atropine.

SUMMARY

Based on limited data, the Mark 1 autoinjector kit (Meridian Medical Technologies, Columbia, Maryland, USA) appears to be the most efficacious antidote delivery system following a nerve agent attack. Symptomatic children under 1 year of age should be given a full atropine dose from the Atropen (Meridian Medical Technologies) (0.5 mg) or Mark 1 kits (2 mg), while children over 1 year of age should be given a full dose of both atropine and pralidoxime from the Mark 1 kit when more accurate weight-based dosing of antidotes is impossible.
