Thoracic trauma in national hospital Abuja, Nigeria: The epidemiology, injury severity and initial management options.

Background: Trauma is the leading cause of death in individuals between the ages of 1 and 44 years and it is the third commonest cause of death regardless of age. Thoracic trauma is a relatively common cause of preventable death among trauma patients. The spectrum of injuries after blunt chest trauma presents a challenging problem to the emergency physician. This study is intended to discuss the epidemiology, severity and initial management strategies in chest trauma patients, in a low income country. Methods: A cross sectional retrospective study among chest trauma patients seen in the emergency room of National Hospital Trauma Centre, Abuja, Nigeria, from January 2015 to December 2017. Relevant patients' information was retrieved from the trauma registry kept in the trauma centre. Data processing and analysis was done using statistical package for social sciences (SPSS) version 24. Test of significance was done where applicable using chi square and student t test, using p value less than 0.05 as significant. Results are presented in tables and figures. Results: A total of 637 patients, male to female ratio of 3.6 and mean age of 34.18 ± 11.34 were enrolled into the study. The most common mechanisms of injury were MVC (54.6%) and assault (23.5%). Blunt injuries were 3.5 times more frequent than the penetrating injuries. The RTS of 12 (76.3%) and the ISS of 1-15 category (52.3%) were the most common scores. Up to 98% of patients were managed non-operatively. Recovery rate was high (89%) with relatively low mortality rate of 4.2%. Conclusion: Majority of thoracic trauma can be managed effectively by employing simple, non-operative procedures such as needle decompression and chest tube insertion. Efforts should be made to include these procedures in the skill set of every medical officer working in the emergency room, particularly in low and middle income countries where there is paucity of emergency physicians.
