The PAWPER tape: A new concept tape-based device that increases the accuracy of weight estimation in children through the inclusion of a modifier based on body habitus.

AIMS Weight estimations in children, which are required when actual weight cannot be measured, are often very inaccurate because of variations in body habitus not accounted for in the estimating methodology. This study was conducted to evaluate the accuracy of the PAWPER tape, a new two-step weight-estimation tape device which employs a length-based habitus-modified weight estimation system. METHODS This was a prospective study in the Emergency Departments of two hospitals in Johannesburg, South Africa on a population of children aged from 1 month to 12 years. Each child had their weight estimated by both the Broselow tape and the PAWPER tape. These weight estimates were then compared against measured weight to determine the bias and precision of the estimation techniques. RESULTS The PAWPER tape performed well, and better than the Broselow tape in every analysis performed. The mean percentage error was -3.8% vs. 0% and the root mean squared percentage error was 9.1% vs. 4.5% for the Broselow tape and PAWPER tape, respectively (p<0.0001). The Broselow tape predicted weight to within 10% of actual weight in 63.6% of children and the PAWPER tape in 89.2% (p<0.0001). The difference between the performances of the Broselow tape and PAWPER tape was most pronounced in children >20 kg, and in children above or below average weight-for-length. CONCLUSIONS The PAWPER tape has been shown to be a simple and reliable method of weight estimation in children and infants. The inclusion of an appraisal of body habitus in the methodology considerably improved the accuracy of weight estimation.

The FIFA medical emergency bag and FIFA 11 steps to prevent sudden cardiac death: setting a global standard and promoting consistent football field emergency care

Life-threatening medical emergencies are an infrequent but regular occurrence on the football field. Proper prevention strategies, emergency medical planning and timely access to emergency equipment are required to prevent catastrophic outcomes. In a continuing commitment to player safety during football, this paper presents the FIFA Medical Emergency Bag and FIFA 11 Steps to prevent sudden cardiac death. These recommendations are intended to create a global standard for emergency preparedness and the medical response to serious or catastrophic on-field injuries in football.

Practical management of sudden cardiac arrest on the football field

Sudden cardiac arrest (SCA) remains a tragic occurrence on the football field. The limits of preparticipation cardiovascular screening make it compulsory that prearranged emergency medical services be available at all football matches to immediately respond to any collapsed player. Management of SCA involves prompt recognition, immediate cardiopulmonary resuscitation (CPR) and early defibrillation. Any football player who collapses without contact with another player or obstacle should be regarded as being in SCA until proven otherwise. An automated external defibrillator (AED), or manual defibrillator if an AED is not available, should be immediately accessible on the field during competitions. This study presents guidelines for a practical and systematic approach to the management of SCA on the football field.

Haiti: the South African perspective

UNLABELLED BACKGROUND AND PROBLEM STATEMENT: The South African response to the Haitian earthquake consisted of two independent non-government organisations (NGOs) working separately with minimal contact. Both teams experienced problems during the deployment, mainly owing to not following the International Search and Rescue Advisory Group (INSARAG) guidelines. CRITICAL AREAS IDENTIFIED To improve future South African disaster responses, three functional deployment categories were identified: urban search and rescue, triage and initial stabilisation, and definitive care. To best achieve this, four critical components need to be taken into account: rapid deployment, intelligence from the site, government facilitation, and working under the auspices of recognised organisations such as the United Nations and the World Health Organization. CONCLUSION The proposed way forward for South African medical teams responding to disasters is to be unified under a leading academic body, to have an up-to-date volunteer database, and for volunteers to be current with the international search and rescue course currently being developed by the Medical Working Group of INSARAG. An additional consideration is that South African rescue and relief personnel have a primary responsibility to the citizens of South Africa, then the Southern African Development Community region, then the rest of the African continent and finally further afield. The commitment of government, private and military health services as well as NGOs is paramount for a unified response.

Cardiac events in football and strategies for first-responder treatment on the field

Background The incidence and outcomes of sudden cardiac arrest (SCA) and global strategies for prevention of sudden cardiac death (SCD) in football are not known. The aim of this study was to estimate the occurrence of cardiac events in football and to investigate the preventive measures taken among the Fédération International de Football Association (FIFA) member associations internationally. Methods A questionnaire was sent to the member associations of FIFA. The first section addressed the previous events of SCA, SCD or unexplained sports-related sudden death within the last 10 years. Further questions focused on football player medical screening strategies and SCA resuscitation response protocols on the field. Results 126 of 170 questionnaires were returned (response rate 74.1%), and 103 questionnaires (60.6%) were completed sufficiently to include in further analysis. Overall, 107 cases of SCA/SCD and 5 unexplained football-associated sudden deaths were reported. These events occurred in 52 of 103 responding associations (50.5%). 23 of 112 (20.5%) footballers survived. 12 of 22 (54.5%) players treated with an available automated external defibrillators (AED) on the pitch survived. A national registry to monitor cardiac events was established in only 18.4% of the associations. Most associations (85.4%) provide regular cardiac screening for their national teams while 75% screen teams of the national leagues. An AED is available at all official matches in 68% of associations. Conclusions National registries to accurately measure SCA/SCD in football are rare and greatly needed. Deficiencies in emergency preparations, undersupply of AEDs on the field during matches, and variability in resuscitation response protocols and training of team-staff members should be addressed to effectively prevent SCD in football.

Family-witnessed resuscitation in emergency departments: Doctors' attitudes and practices

BACKGROUND Resuscitation of patients occurs daily in emergency departments. Traditional practice entails family members remaining outside the resuscitation room. OBJECTIVE We explored the introduction of family witnessed resuscitation (FWR) as it has been shown to allow closure for the family when resuscitation is unsuccessful and helps them to better understand the last moments of life. RESULTS Attending medical doctors have concerns about this practice, such as traumatisation of family members, increased pressure on the medical team, interference by the family, and potential medico-legal consequences. There was not complete acceptance of the practice of FWR among the sample group. CONCLUSION Short-course training such as postgraduate advanced life support and other continued professional development activities should have a positive effect on this practice.The more experienced doctors are and the longer they work in emergency medicine, the more comfortable they appear to be with the concept of FWR and therefore the more likely they are to allow it. Further study and course attendance by doctors has a positive influence on the practice of FWR.

Assessment of safe endotracheal tube cuff pressures in emergency care - time for change?

2 To avoid tracheal injury due to emergency intubation, it is important that ETT cuff over-inflation is avoided in the pre-hospital and ED phases of emergency care. Although ETT cuff pressure manometry is optimal in determining safe ETT cuff pressure, it is standard practice in the ED and in the pre-hospital emergency care environment to assess ETT cuff pressure using palpation of the cuff s pilot balloon - a qualitative technique prone to subjective interpretation. Aimsaims of the study were to describe the ability of a convenience sample of practising ALS paramedics and emergency doctors in Johannesburg to accurately estimate safe ETT cuff pressures using palpation of the cuff s pilot balloon alone, and to determine whether there was any dependence between correctness of ETT cuff estimation and the practitioners years of clinical experience and estimated monthly number of intubations.

F-MARC: promoting the prevention and management of sudden cardiac arrest in football

Sudden cardiac death is the most common cause of unnatural death in football. To prevent and urgently manage sudden cardiac arrest on the football field-of-play, F-MARC (FIFA Medical and Research Centre) has been fully committed to a programme of research, education, standardisation and practical implementation. This strategy has detected football players at medical risk during mandatory precompetition medical assessments. Additionally, FIFA has (1) sponsored internationally accepted guidelines for the interpretation of an athletes ECG, (2) developed field-of-play-specific protocols for the recognition, response, resuscitation and removal of a football player having sudden cardiac arrest and (3) introduced and distributed the FIFA medical emergency bag which has already resulted in the successful resuscitation of a football player who had a sudden cardiac arrest on the field-of-play. Recently FIFA, in association with the Institute of Sports and Preventive Medicine in Saarbrücken, Germany, established a worldwide Sudden Death Registry with a view to documenting fatal events on the football field-of-play. These activities by F-MARC are testimony to FIFAs continued commitment to minimising sudden cardiac arrest while playing football.

Glass injuries seen in the emergency department of a South African district hospital

BACKGROUND The emergency department of Embhuleni Hospital frequently manages patients with glass-related injuries. This study assessed these injuries and the glass that caused them in more detail. AIM The objectives of our study included determining the type of glass causing these injuries and describing the circumstances associated with different types of glass injuries. SETTING The emergency department of Embhuleni Hospital in Elukwatini, Mpumalanga province, South Africa. METHODS This was a cross-sectional study with a sample size of 104 patients. Descriptive statistics were used to assess the characteristics of the glass injuries. RESULTS Five different types of glass were reported to have caused the injuries, namely car glass (7.69%), glass ampoules (3.85%), glass bottles (82.69%), glass windows (3.85%) and street glass shards (1.92%). Glass bottle injuries were mainly caused by assaults (90.47%) and most victims were mostly young males (80.23%). The assaults occurred at alcohol-licensed premises in 65.11% of cases. These injuries occurred mostly over weekends (83.72%), between 18:00 and 04:00. The face (34.23%) and the scalp (26.84%) were the sites that were injured most often. CONCLUSION Assault is the most common cause of glass injuries, usually involving young men at alcohol-licensed premises. Glass injuries generally resulted in minor lacerations, with few complications (2.68%).BACKGROUND The emergency department of Embhuleni Hospital frequently manages patients with glass-related injuries.
