Identifying the need for pre-hospital and emergency care in the developing world: a case study in Chennai, India.

OBJECTIVES: Increasing industrialization in the developing world has contributed to an epidemiological transition in disease pattern from infectious disease as a primary cause of morbidity and mortality, to more chronic illness such as heart disease and trauma. This study was done in order to assess the effectiveness of pre-hospital and emergency care as the health care needs of the population changes and to make recommendations to meet the growing need for organized emergency services in that community. METHODS: Sundaram Medical Foundation Hospital in the town of Annanagar, Chennai, India was our study site. Statistics describing the health status, demographic, and socio-ecoomic profiles of the community were obtained from a published community survey. Information regarding availability of resources in the hospitals for management of trauma and cardio-vascular emergencies was obtained from unpublished survey results of the local hospitals. Retrospective data was obtained from trauma and ambulance registries regarding trauma related admissions, death and pre-hospital assistance. RESULTS: Data analysis revealed increasing mortality from trauma and cardiovascular etiologies. Hospital statistics showed that 1/3 of the annual hospitalizations were from trauma and acute coronary syndromes. Half the trauma victims had no formal prehospital intervention. Standard of care in the emergency departments varied considerably with less than half of them carrying defibrillators and only a third of them carrying defirbillators and only a third of them carrying intubation equipment. CONCLUSION: As developing countries begin to urbanize and grow, so do their health care needs. The current system does not meet the needs of increased mortality from trauma and cardiovascular disease. We have suggested necessary changes for establishment of emergency medical services to meet the evolving health care needs.

Do the length-based (Broselow) Tape, APLS, Argall and Nelson's formulae accurately estimate weight of Indian children?

This study was aimed at validating the usefulness of a length based pediatric emergency tape (Broselow) in an Indian population. The secondary objective was to validate age based weight estimation formulae (Nelson, Argalls, APLS) for emergency needs (doses, sizes). This cross sectional study was done at a tertiary teaching hospital on a sample of 500 children attending outpatient clinic. Inclusion criteria was age between 1 month to 12 years. Children who were unstable, uncooperative or critically ill requiring emergency care and those measuring more than 145 cm in length or weighing more than 35 kg weight were excluded from the study. Measurement of actual weights, calculation of weight, adrenaline dose, fluid bolus and endotracheal tube size was done by all four methods. Results indicated good positive correlation between actual measured weights and weights estimated using Broselow Tape (r = 0.974), APLS (r = 0.902), Argalls modification (r = 0.902), and combined Nelson formulae (0.935). However, specific Nelson formulas for 7-12 yr and 3-12 mo were especially poor in correlation. Bland-Altman Plots comparing actual weight showed least mean bias for Broselow Tape estimations in < 15 kg group (0.080 +/- 0.96 kg) and maximum bias with Nelsons formula for 7 to12 yr (5.204 +/- 4.272 kg). For adrenaline doses and fluid bolus calculations, Broselow estimations were valid estimates. Broselow tape did underestimate endotracheal tube size (mean bias -0.53 +/- 0.18). To conclude, length based pediatric emergency tape (Broselow) correlates well with overall emergency decision making process in our setting. This is especially validated in the age group 0.1 to 6.7 yr weighing less than 15 kg.

Uso del tubo de Sengstaken-Blakemore en el tratamiento de varices esofagicas sangrantes / Use of Sengstaken-Blakemore tube for treatment of bleeding esophageal varices

La hemorragia gastrointestinal alta producida por varices esofagicas sangrantes, origina un cuadro clinico serio en cualquier paciente. La gran presion portal y la relativa inasequible localizacion de las varices, plantean un grave problema al cirujano. El tubo de Sengstaken Blakemore es hasta ahora el mejor metodo para corregir la hemorragia severa, pero el medico se debe familiarizar con su uso, pues se han descrito complicaciones delicadas si no se tiene cuidados especiales. Se presenta aqui una manera correcta de empleo, mediante un casco protector con una barra metalica que sirve de anclaje para fijar el tubo adecuadamente y permitir que el balon gastrico se acomode bien al area cardioesofagica donde se encuentra la mayor parte de las varices. Esta tecnica se ha utilizado adecuadamente en mas de 40 enfermos en los ultimos 4 anos en el Hospital Universitario del Valle, sin observar complicaciones
