Who are the trauma team leaders across Canada? A national survey evaluating the profession in adult and pediatric level one trauma centres.

OBJECTIVES: Trauma Team Leaders (TTLs) are critical for coordinating and leading trauma resuscitations. This survey sought to characterize the demographics and professional practices of Canadian TTLs at level one trauma centres. As a secondary objective, this information will be utilized to inform the operational goals of the Trauma Association of Canada (TAC) TTL Committee. METHODS: A detailed survey, developed by the TAC board of directors and TTL committee leads, was sent to 225 TTLs across Canada's level one trauma centres. TTLs were identified via contacting trauma directors at each level one centre, in addition to public registry searches. This survey captured demographics, professional background, resuscitation practices, trauma team composition, and TTL involvement in trauma responses. RESULTS: The response rate was 41.7%. Mean respondent age was 42 (SD 7.4) and 71.0% were male. Most TTLs trained in emergency medicine (53.1%) or general surgery (25.5%); 63.8% underwent TTL training: either via a trauma surgery fellowship or TTL fellowship. All centres have a massive hemorrhage protocol implemented, and there is no large variation between the rates of use of cryoprecipitate and fibrinogen, nor the ratio of blood products transfused (2:1 vs 1:1). Most TTL respondents intend to participate in a TTL group associated with TAC (85.1%). CONCLUSION: The results of this survey will contribute to the recognition of TTLs as a crucial role in the initial phase of care of severely injured trauma patients and serves as the first publication to document professional backgrounds and practices of Canadian TTLs at level one trauma centres. All the information gathered via this survey will be used by the TAC TTL Committee, which will focus on several initiatives such as the dissemination of best practice guidelines and creation of a TTL stream at the TAC Annual Conference.

RéSUMé: OBJECTIFS: Les chefs d'équipe de traumatologie (TTL) sont essentiels pour coordonner et diriger les réanimations traumatiques. Cette enquête visait à caractériser la démographie et les pratiques professionnelles des TTL canadiens dans les centres de traumatologie de niveau 1. À titre d'objectif secondaire, cette information sera utilisée pour éclairer les objectifs opérationnels du Comité TTL de l'Association canadienne de traumatologie (ATC). MéTHODES: Un sondage détaillé, élaboré par le conseil d'administration de l'ATC et les responsables des comités de TTL, a été envoyé à 225 TTL dans les centres de traumatologie de niveau 1 du Canada. Les TTL ont été identifiés en contactant les directeurs de traumatologie de chaque centre de niveau 1, en plus des recherches dans le registre public. Cette enquête a porté sur la démographie, les antécédents professionnels, les pratiques de réanimation, la composition de l'équipe de traumatologie et la participation de la TTL aux réponses traumatologiques. RéSULTATS: Le taux de réponse était de 41,7 %. L'âge moyen des répondants était de 42 ans (ET 7,4) et 71,0 % étaient des hommes. La plupart des TTL ont suivi une formation en médecine d'urgence (53,1%) ou en chirurgie générale (25,5%); 63,8% ont suivi une formation TTL : soit via une bourse en chirurgie traumatologique ou une bourse TTL. Tous les centres ont mis en œuvre un protocole d'hémorragie massive, et il n'y a pas de grande variation entre les taux d'utilisation du cryoprécipité et du fibrinogène, ni entre le rapport des produits sanguins transfusés (2:1 vs 1:1). La plupart des répondants TTL ont l'intention de participer à un groupe TTL associé au TAC ( 85,1 %). CONCLUSION: Les résultats de ce sondage contribueront à la reconnaissance des TTL comme un rôle crucial dans la phase initiale des soins aux patients ayant subi un traumatisme grave et serviront de première publication pour documenter les antécédents et les pratiques professionnelles des TTL canadiens au niveau un centres de traumatologie. Toutes les informations recueillies dans le cadre de cette enquête seront utilisées par le Comité TAC TTL, qui se concentrera sur plusieurs initiatives telles que la diffusion de lignes directrices sur les meilleures pratiques et la création d'un flux TTL à la conférence annuelle TAC.

Time to operating room matters in modern management of pancreatic injuries: A national review on the management of adult pancreatic injury at Canadian level 1 trauma centers.

BACKGROUND: Pancreatic injuries are rare, difficult to diagnose, and complex to manage despite multiple published guidelines. This study was undertaken to evaluate the current diagnosis and management of pancreatic trauma in Canadian trauma centers. METHODS: This is a multi-institutional retrospective study from 2009 to 2014 including patients from eight level 1 trauma centers across Canada. All patients with a diagnosis of pancreatic trauma were included. Demographics, injury characteristics, vital signs on admission, and type of management were collected. Outcomes measured were mortality and pancreas-related morbidity. RESULTS: Two hundred seventy-nine patients were included. The median age was 29 years (interquartile range, 21-43 years), 72% were male, and 79% sustained blunt trauma. Pancreatic injury included the following grades: I, 26%; II, 28%; III, 33%; IV, 9%; and V, 4%. The overall mortality rate was 11%, and the pancreas-related complication rate was 25%. The majority (88%) of injuries were diagnosed within 24 hours of injury, primarily (80%) with a computed tomography scan. The remaining injuries were diagnosed with ultrasound (6%) and magnetic resonance cholangiopancreatography (MRCP) (2%) and at the time of laparotomy or autopsy (12%). One hundred seventy-five patients (63%) underwent an operative intervention, most commonly a distal pancreatectomy (44%); however, there was great variability in operative procedure chosen even when considering grade of injury. CONCLUSION: Pancreatic injuries are associated with multiple other injuries and have significant morbidity and mortality. Their management demonstrates significant practice variation within a national trauma system. LEVEL OF EVIDENCE: Therapeutic/care management, level V; Prognostic and epidemiological, level IV.

Esophageal Balloon-Directed Ventilator Management for Postpneumonectomy Acute Respiratory Distress Syndrome.

OBJECTIVE: Postpneumonectomy patients may develop acute respiratory distress syndrome (ARDS). There is a paucity of data regarding the optimal management of mechanical ventilation for postpneumonectomy patients. Esophageal balloon pressure monitoring has been used in traditional ARDS patients to set positive end-expiratory pressure (PEEP) and minimize transpulmonary driving pressure (ΔP L), but its clinical use has not been previously described nor validated in postpneumonectomy patients. The primary objective of this report was to describe the potential clinical application of esophageal pressure monitoring to manage the postpneumonectomy patient with ARDS. DESIGN: Case report. Setting. Surgical intensive care unit (ICU) of a university-affiliated teaching hospital. Patient. A 28-year-old patient was involved in a motor vehicle collision, with a right main bronchus injury, that required a right-sided pneumonectomy to stabilize his condition. In the perioperative phase, they subsequently developed ventilator-associated pneumonia, significant cumulative positive fluid balance, and ARDS. Interventions. Prone positioning and neuromuscular blockade were initiated. An esophageal balloon was inserted to direct ventilator management. Measurements and Main Results. V T was kept around 3.6 mL/kg PBW, ΔP L at ≤14 cm H2O, and plateau pressure at ≤30 cm H2O. Lung compliance was measured to be 37 mL/cm H2O. PEEP was optimized to maintain end-inspiratory transpulmonary pressure (P L) < 15 cm H2O, and end-expiratory P L between 0 and 5 cm H2O. The maximal ΔP L was measured to be 11 cm H2O during the care of this patient. The patient improved with esophageal balloon-directed ventilator management and was eventually liberated from mechanical ventilation. CONCLUSIONS: The optimal targets for V T remain unknown in the postpneumonectomy patient. However, postpneumonectomy patients with ARDS may potentially benefit from very low V T and optimization of PEEP. We demonstrate the application of esophageal balloon pressure monitoring that clinicians could potentially use to limit injurious ventilation and improve outcomes in postpneumonectomy patients with ARDS. However, esophageal balloon pressure monitoring has not been extensively validated in this patient population.
