Pre-hospital transport times and survival for Hypotensive patients with penetrating thoracic trauma

Background: Achieving definitive care within the “Golden Hour” by minimizing response times is a consistent goal of regional trauma systems. This study hypothesizes that in urban Level I Trauma Centers, shorter pre-hospital times would predict outcomes in penetrating thoracic injuries. Materials and Methods: A retrospective cohort study was performed using a statewide trauma registry for the years 1999-2003. Total pre-hospital times were measured for urban victims of penetrating thoracic trauma. Crude and adjusted mortality rates were compared by pre-hospital time using STATA statistical software. Results: During the study period, 908 patients presented to the hospital after penetrating thoracic trauma, with 79% surviving. Patients with higher injury severity scores (ISS) were transported more quickly. Injury severity scores (ISS) ≥16 and emergency department (ED) hypotension (systolic blood pressure, SBP <90) strongly predicted mortality (P < 0.05 for each). In a logistic regression model including age, race, and ISS, longer transport times for hypotensive patients were associated with higher mortality rates (all P values <0.05). This was seen most significantly when comparing patient transport times 0-15 min and 46-60 min (P < 0.001). Conclusion: In victims of penetrating thoracic trauma, more severely injured patients arrive at urban trauma centers sooner. Mortality is strongly predicted by injury severity, although shorter pre-hospital times are associated with improved survival. These results suggest that careful planning to optimize transport time-encompassing hospital capacity and existing resources, traffic patterns, and trauma incident densities may be beneficial in areas with a high burden of penetrating trauma.

Thoracostomy tubes: A comprehensive review of complications and related topics.

Tube thoracostomy (TT) placement belongs among the most commonly performed procedures. Despite many benefits of TT drainage, potential for significant morbidity and mortality exists. Abdominal or thoracic injury, fistula formation and vascular trauma are among the most serious, but more common complications such as recurrent pneumothorax, insertion site infection and nonfunctioning or malpositioned TT also represent a significant source of morbidity and treatment cost. Awareness of potential complications and familiarity with associated preventive, diagnostic and treatment strategies are fundamental to satisfactory patient outcomes. This review focuses on chest tube complications and related topics, with emphasis on prevention and problem-oriented approaches to diagnosis and treatment. The authors hope that this manuscript will serve as a valuable foundation for those who wish to become adept at the management of chest tubes.

Bronchoalveolar lavage amylase is associated with risk factors for aspiration and predicts bacterial pneumonia.

Objectives:Aspiration of oropharyngeal or gastric contents into the respiratory tract leads to a spectrum of disorders with high morbidity. Aspiration is a diagnostic dilemma, because clinical characteristics and diagnostic tests are not effective predicting or confirming aspiration. We sought to determine whether &agr;-amylase, a protein secreted by salivary glands and the pancreas, is elevated in bronchoalveolar lavage specimens in patients with clinical risk factors for aspiration and whether bronchoalveolar lavage amylase predicts bacterial pneumonia. Design:Retrospective analysis. Setting:Five adult ICUs at a tertiary care urban medical center. Patients:Mechanically ventilated patients who underwent either bronchoscopic or nonbronchoscopic bronchoalveolar lavage within 72 hrs of endotracheal intubation between August 1, 2008 and June 30, 2010. Measurements and Main Results:A total of 296 bronchoalveolar lavage amylase results from 280 patients were included in the analysis, and 155 bronchoalveolar lavage amylase specimens were obtained from patients with at least one predefined preintubation risk factor (altered consciousness, swallowing dysfunction, difficult intubation, peri-intubation vomiting, or cardiac arrest). Bronchoalveolar lavage amylase concentration increased as the number of preintubation risk factors increased (p < 0.001). In addition, bronchoalveolar lavage amylase was elevated in patients with bacterial pneumonia (cfu/mL ≥ 104) (p < 0.001). The area under the receiver operator curve for the ability of bronchoalveolar lavage amylase to differentiate between positive and negative bronchoalveolar lavage culture was 0.67 (95% confidence interval, 0.60–0.75). The lower 95% confidence interval for bronchoalveolar lavage amylase in patients with at least one preintubation risk factor for aspiration was 125.9 units/L. In multivariate analysis, bronchoalveolar lavage amylase < 125 units/L was associated with significantly lower odds of bacterial pneumonia (odds ratio 0.39, 95% confidence interval 0.21–0.71, p = 0.002). Conclusions:Elevated bronchoalveolar lavage amylase is associated with risk factors for aspiration and may predict bacterial pneumonia. Bronchoalveolar lavage amylase may be useful as an early screening tool to guide management of patients suspected of aspiration.

Trauma system development in low- and middle-income countries: a review

BACKGROUND Trauma systems in resource-rich countries have decreased mortality for trauma patients through centralizing resources and standardizing treatment. Rapid industrialization and urbanization have increased the demand for formalized emergency medical services and trauma services (EMS and TS) in low- and middle-income countries (LMICs). This systematic review examines initiatives to develop EMS and TS systems in LMICs to inform the development of comprehensive prehospital care systems in resource-poor settings. MATERIALS AND METHODS EMS and TS system development publications were identified using MEDLINE, PubMed, and Scopus databases. Articles addressing subspecialty skill sets, public policy, or physicians were excluded. Two independent reviewers assessed titles, abstracts, and full texts in a hierarchical manner. RESULTS A total of 12 publications met inclusion criteria, and 10 unique LMIC EMS and TS programs were identified. Common initiatives included the integration of existing EMS and TS services and provision of standardized training and formalized certification processes for prehospital care providers, as well as the construction of a conceptual framework for system development through the public health model. CONCLUSIONS There is no single model of EMS and TS systems, and successful programs are heterogeneous across regions. Successful EMS and TS systems share common characteristics. A predevelopment needs assessment is critical in identifying existing EMS and TS resources as a foundation for further development. Implementation requires coordination of preexisting resources with cost-effective initiatives that involve local stakeholders. High-impact priority areas are identified to focus improvements. Financial stresses and mismatching of resources in LMICs are common and are more commonly encountered when implementing a high-income model EMS and TS in an LMIC. Preimplementation and postimplementation evaluations can determine the efficacy of initiatives to strengthen EMS and TS systems.

The 2014 Academic College of Emergency Experts in India's INDO‑US Joint Working Group (JWG) White Paper on "Developing Trauma Sciences and Injury Care in India"

It is encouraging to see the much needed shift in the understanding and recognition of the concept of “burden of disease” in the context of traumatic injury. Equally important is understanding that the impact of trauma burden rivals that of nontraumatic morbidities. Subsequently, this paradigm shift reinstates the appeal for timely interventions as the standard for management of traumatic emergencies. Emergency trauma care in India has been disorganized due to inadequate sensitivity toward patients affected by trauma as well as the haphazard, nonuniform acceptance of standardization as the norm. Some of the major hospitals across various regions in the country do have trauma care units, but even those lack protocols to ensure that all trauma cases are handled by those units, largely owing to lack of structured referral system. As a first step to reform the state of trauma care in the country, a detailed overview is needed to gain insight into the prevailing reality. The objectives of this paper are to thus weave a foundation based on the statistical and qualitative burden of trauma in the country; the available infrastructure of trauma care centers equipped to deal with trauma; the need and scope of standardized protocols for intervention; and most importantly, the application of these in shaping educational initiatives in advancing emergency trauma care in the country.

Academic College of Emergency Experts in India's INDO-US Joint Working Group (JWG) White Paper on the Integrated Emergency Communication Response Service in India: Much more than just a number!

The proposal for an integrated national emergency number for India is garnering a lot of enthusiasm and stimulating debate. This ambitious project has a two-part paradigm shift to set in; the first being the integration into a single number and the infrastructure required for setting up and operating this number such that a call can be received and identified. The second is the submerged part of the iceberg: That of the ability to respond to a call and deliver the appropriate emergency service. The first part is more technical and has potential precedents like the 911 phone hotline, for example, to emulate. The main premise of this paper is that the second part is a rather subjective exercise largely determined by the realities of existing public infrastructure in a specific geographical area with respect to emergency services management, especially medical care. Consequently, we highlight the key areas of both precall preparedness and postcall execution that need to be reviewed prior to going live with an integrated number on a national scale.

Laparoscopy in trauma: An overview of complications and related topics

The introduction of laparoscopy has provided trauma surgeons with a valuable diagnostic and, at times, therapeutic option. The minimally invasive nature of laparoscopic surgery, combined with potentially quicker postoperative recovery, simplified wound care, as well as a growing number of viable intraoperative therapeutic modalities, presents an attractive alternative for many traumatologists when managing hemodynamically stable patients with selected penetrating and blunt traumatic abdominal injuries. At the same time, laparoscopy has its own unique complication profile. This article provides an overview of potential complications associated with diagnostic and therapeutic laparoscopy in trauma, focusing on practical aspects of identification and management of laparoscopy-related adverse events.

Academic Global Surgery

Globally, rising economies are leading to an epidemiologic transition wherein injury, cancer, and congenital malformations are becoming much more prominent public health threats in low- and middle-income countries (LMIC) (Learmonth (1951) The contributions of surgery to preventive medicine. Oxford University Press, Geoffrey Cumberlege, Publisher to the University, London, p 20). The Lancet Commission on Global Surgery, the Disease Control Priorities-3 project, and the World Health Assembly 2015 resolution on Emergency and Essential Surgical Care and Anesthesia all underscored the role of surgery as an essential component of the comprehensive global public health agenda (http://dcp-3.org/surgery; http://www.globalsurgery.info/). With the need to improve the very infrastructure of surgical-care systems to achieve this, there has been a paradigm shift from traditional reliance on intermittent short-term volunteerism toward a strengthening of the education and research pillars for surgical healthcare in developing regions, a role ideally suited for academic surgery (Schecter, JAMA Surg 150(7):605–606, 2015; Smith, Br J Surg 102:575–576, 2015). Academic Global Surgery (AGS) leverages the scientific approach, educational focus, and outcome examination that characterize academic medicine and applies them toward the strengthening of surgical care in under-resourced regions, international or domestic (Swaroop and Krishnaswami, Academic global surgery. Springer Publ, 2016).

Burden of road traffic injuries in Nepal: results of a countrywide population-based survey

BACKGROUND Road traffic injury has emerged as a leading cause of mortality, contributing to 2·1% of deaths globally and is predicted to be the third highest contributor to the global burden of mortality by 2020. This major public health problem disproportionately affects low-income and middle-income countries, where such incidents are too often underreported. Our study aims to explore the epidemiology of road traffic injurys in Nepal at a population level via a countrywide study. METHODS The Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool, a cluster randomised, cross-sectional nationwide survey, was conducted in Nepal between May 25, and June 12, 2014. Two-stage cluster sampling was performed: 15 of 75 districts were chosen randomly proportional to population; within each district, after stratification for urban and rural, and three clusters were randomly chosen. Questions were structured anatomically and designed around a representative spectrum of surgical conditions. Road traffic injury-related results were reported. FINDINGS 1350 households and 2695 individuals were surveyed with a response rate of 97%. 75 road traffic injuries were reported in 72 individuals (2·67% [95% CI 2·10-3·35] of the study population), with a mean age of 33·2 years (SD 1·85). The most commonly affected age group was 30-44 years, with females showing significantly lower odds of sustaining a road traffic injury than men (crude odds ratio 0·29 [95% CI 0·16-0·52]). Road traffic injuries composed 19·8% of the injuries reported. Motorcycle crashes were the most common road traffic injuries (48·0%), followed by car, truck, or bus crashes (26·7%), and pedestrian or bicycle crashes (25·3%). The extremity was the most common anatomic site injured (74·7%). Of the 80 deaths reported in the previous year, 7·5% (n=6) were due to road traffic injuries. INTERPRETATION This study provides the epidemiology of road traffic injuries at a population-based level in the first countrywide surgical needs assessment in Nepal. WHO reported that mortality due to road traffic injuries in Nepal in 2011 was 1·7%, whereas our study reported 7·5%, consistent with the concept of underreporting of deaths in police and hospital level data noted in previous literature. Road traffic injuries continue to be a significant problem in Nepal, probably greater than previously reported; future efforts should focus on addressing this growing epidemic through preventive and mitigating strategies.
