The European Resuscitation Council's paediatric life support course 'Advanced Paediatric Life Support'.

The poor outcome for resuscitation from cardiopulmonary arrest in childhood is widely recognised. The European Resuscitation Council has adopted the Advanced Paediatric Life Support course (originating in the UK and now available in a number of countries) as its course for providers caring for children. This paper outlines the course content and explains its remit, which is to reduce avoidable deaths in childhood by not only resuscitation from cardiac arrest but, more effectively, by recognising and treating in a timely and effective fashion life-threatening illness and injury in infants and children. Two related courses Paediatric Life Support, a less intense course for less advanced providers, and Pre-Hospital Paediatric Life Support for immediate care providers are also described.

The capability of accident and emergency departments to safely decontaminate victims of chemical incidents.

OBJECTIVES: To evaluate the capability of accident and emergency (A&E) departments in six health regions of England to safely decontaminate casualties exposed to hazardous chemicals. METHODS: In January 1999 a postal questionnaire was sent to the clinical director of all A&E departments in Trent, North and South Thames, South and West, North West and, Anglia and Oxford Health Regions. The questionnaire inquired about characteristics of the department, decontamination facilities and equipment, and staff training. Nonresponders were sent a second questionnaire and contacted by telephone if they failed to respond to the second mailing. RESULTS: 308 of 326 departments identified (94%) returned a questionnaire. There was no significant difference in response rate by region (p = 0.99). Analysis was restricted to 154 major departments seeing more than 20000 new attendances per year. Of these 154 departments, 109 (71%) had a written chemical incident plan but only 55 (36%) maintained a list of nearby industrial chemical sites. Fifty nine departments (38%) stated that members of staff had received training in the management of chemically contaminated casualties in the preceding year. Eighteen departments (12%) possessed the level of personal protective equipment (PPE) recommended for decontamination by the Ambulance Services Association. Ninety six departments (62%) had a designated decontamination room but only seven (7%) of them incorporated all the features generally considered necessary for safe decontamination. Forty one units (27%) had the capability to decontaminate casualties outside of the department either with warm water from a shower attachment or with a mobile decontamination unit. Thirty six departments (23%) had neither a decontamination room nor the ability to decontaminate casualties outside the department. Only 16 units (10%) had both adequate PPE and either a decontamination room or the capability to decontaminate outside the department. CONCLUSIONS: This study has identified deficiencies in the current NHS capability to respond to chemical incidents. To resolve this, nationally recognised standards for decontamination facilities, equipment and training should be formulated, agreed and implemented.

Modification of the cardiovascular response to hemorrhage by somatic afferent nerve stimulation with special reference to gut and skeletal muscle blood flow.

BACKGROUND: Tissue injury modifies heart rate and blood pressure responses to hemorrhage. The effect of concomitant injury on the hemorrhage-induced redistribution of cardiac output is much less clear. However, if injury elicits the visceral alerting response of the defense reaction, then a change in this redistribution of peripheral blood flow might be expected. If such a change compromised the gut circulation, then it might explain the deleterious effects of injury on the ability to withstand hemorrhage. METHODS: Immature pigs anesthetized with Saffan were bled 30% of blood volume with or without concomitant somatic afferent (brachial) nerve stimulation (to mimic injury). In addition to global cardiovascular and oxygen transport variables, blood flow was measured in the cranial mesenteric (gut) and right femoral (skeletal muscle) arteries after a 60-minute stabilization period after surgery, at the end of the 30-minute hemorrhage, and after a 30-minute shock period. RESULTS: Hemorrhage induced the expected cardiovascular and oxygen transport changes accompanied by a reduction in skeletal muscle blood flow and a 55% increase in skeletal muscle vascular resistance, but gut blood flow and vascular resistance were unchanged. However, in the presence of brachial nerve stimulation, the pattern of response to hemorrhage was modified, such that gut blood flow was now reduced and gut vascular resistance increased. CONCLUSION: The sparing of the gut circulation after hemorrhage was abolished in the presence of "injury." This finding is consistent with injury eliciting the defense reaction and may help explain the deleterious effects of injury on resistance to hypovolemia.

Delphi study into planning for care of children in major incidents.

This paper describes a Delphi study used to identify and improve areas of concern in the planning of care for children in major incidents. The Delphi was conducted over three rounds and used a multidisciplinary panel of 22 experts. Experts were selected to include major incident, immediate care, emergency medicine, and paediatric specialists. This paper presents a series of consensus statements that represent the Delphi group's opinion on the management of children in major incidents. The statements cover all phases of major incident planning and response. Paediatric services may play a vital role in the preparation and response to a major incident involving children. This paper represents a consensus view on how best to plan and respond to major incidents involving children. An accompanying paper describes the practical implementation of this guidance.

Planning for major incidents involving children by implementing a Delphi study.

This paper provides a practical approach to the difficult problem of planning for a major incident involving children. It offers guidance on how general principles resulting from an expert Delphi study can be implemented regionally and locally. All phases of the response are covered including preparation, management of the incident, delivery of medical support during the incident, and recovery and support. A check list for regional planners is provided. Supplementary equipment is discussed and action cards for key roles in the paediatric hospital response are shown. Particular emphasis is placed on management of the secondary-tertiary interface including the special roles of paediatric assessment teams and paediatric transfer teams. A paediatric primary triage algorithm is provided. The important role of local interpretation of guidance is emphasised.
