Background: Venous thromboembolism (VTE) is a common and serious complication seen in patients with trauma. Guidelines recommend the routine use of pharmacologic prophylaxis; however, compliance rates vary widely. The aim of this study was to describe the clinical practice related to VTE prophylaxis in the first 24 hours after injury at our level 1 Canadian trauma centre and the impact of a thrombosis consultation service. Methods: We performed a retrospective review of the health records of adult patients with trauma admitted between Jan. 1, 2012, and June 30, 2013. The rate of VTE was ascertained. The use of an initial prophylactic regimen, potential contraindications to prophylaxis and involvement of the thrombosis service were determined. Results: A total of 633 patients were included, 459 men and 174 women with a mean age of 47.4 years. The mean Injury Severity Score was 15.8. The overall VTE rate was 2.8%. A total of 514 patients (81.2%) received VTE prophylaxis, mechanical in 302 (47.7%) and pharmacologic in 231 (36.5%) (19 patients received both types). The thrombosis service was involved in the care of 164 patients (25.9%). Patients seen by the thrombosis service were more likely to receive VTE prophylaxis than those not seen by the service (145 [88.4%] v. 369 [78.7%], p < 0.01). Conclusion: Compliance with VTE prophylaxis administration was suboptimal, and opportunities for improvement exist. The involvement of a thrombosis consultation service appears to improve compliance with VTE prophylaxis, and augmented use of this service may improve clinical outcomes. Contexte : La thromboembolie veineuse (TEV) est une complication grave et fréquente chez les patients vus en traumatologie. Les lignes directrices recommandent l'utilisation systématique d'une prophylaxie pharmacologique; par contre, les taux de conformité aux lignes directrices varient beaucoup. Le but de cette étude était de décrire la pratique clinique en matière de thromboprophylaxie dans notre centre de traumatologie canadien de niveau 1 au cours des 24 premières heures suivant un traumatisme et l'impact d'un service de prévention des thromboses.
Objective: To assess the accuracy of emergency physicians (EPs) in the interpretation of non-contrast CT Brain (NCCT Brain) by examining the inter rater reliability between EPs and radiology specialists. Methodology: A four months prospective cohort study was conducted at emergency department of King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia. We studied the daily performance of our EPs, and compared it to the radiological report issued within the week after. Data were analyzed by calculating sensitivity, specificity, accuracy and agreement (kappa statistic), using radiology report as the reference standard. Results : Out of 241 cases eligible for the study, 210 (87.14%) were concordant, and 31 (12.86%) were discordant. The agreement (kappa) was to be 0.64. Conclusion : We concluded that our EPs are moderately accurate at interpreting NCCT Brain studies. Further education and training programs were necessary for all our EPs to improve the accuracy. Further studies are required to determine the most cost-effective method of minimizing consequential misinterpretations.
Pneumomediastinum is defined as the presence of air in the mediastinum. Trauma to the nearby organs can cause air to escape into surrounding tissues that may manifest clinically as severe chest pain, voice change, or shortness of breath. However, pneumomediastinum can present spontaneously in healthy individuals with no inciting factors in which case the condition is termed spontaneous pneumomediastinum (SPM). Pneumomediastinum can be challenging to manage due to the absence of clear guidelines for the diagnosis and management. We present the case of a 21-year-old with no previous medical history who presented with chest pain that was aggravated by speech and breath. The pain was of sudden onset preceded by smoking at 2:00 am. The patient was tachycardic, tachypnoeic with crepitation on palpation and a crunch sound (Hamman’s sign) on auscultation. The patient rated the pain as 5/10 on a 11-point numerical pain rating scale, which then evolved to 10/10. The patient did not have fever, loss of consciousness (LOC), diaphoresis, history of trauma, or previous similar presentation. There were no other associated symptoms. A chest X-ray (posteroanterior (PA) and lateral view) showed pneumomediastinum, but laboratory tests results were otherwise normal. The patient was observed in the emergency room overnight. He remained stable, his tachycardia settled, and there was no leukocytosis or desaturation; however, tachypnea was observed. His pain symptoms were treated with analgesia as needed and the patient was discharged home in a stable condition, to be followed on an outpatient basis. Spontaneous pneumomediastinum can be challenging to manage due to the lack of reliable incidence data as well as the absence of clear management guidelines. Further research will aid in understanding the true incidence of SPM in Saudi Arabia and help in establishing a consensual approach and treatment guidelines to deal with SPM in otherwise healthy individuals. To the best of our knowledge, this is the first case of SPM in a young male reported from a tertiary hospital in Riyadh, Saudi Arabia.
