Introduction: Trauma is a major cause of mortality and disability all over the world and causes morethan 50 million deaths each year. Traumatic damages are increasing rapidly in a way that the world healthorganization states that traffic road injuries are going to be the third global cause of death and disabilityuntil 2020. The aim of this study is to investigate the relationship between the number and anatomicalregion of
injury with the mechanism of trauma in multiple trauma patients.Method: This cross-sectional study was performed on multiple trauma patients referred to EmergencyCenter of Imam Hospital in a sari. Demographic information and variables such as the mechanism oftrauma, the number and anatomical region of
injury were collected and recorded. Data were analyzedstatistically using SPSS version 20.Findings: 220 patients with average age 38.59±21.03 were included in this study. 158 individuals weremale (71.8%) and 62 individuals were female (28.2%). The average age of males and females was37.92±18.99 and 40.29±25.94 respectively. The most frequently observed trauma cases were in the agegroup of 21 to 30. The most frequent causes of trauma were the car to a car accident (44.5%), fallingdown from height (20%) and motor to a car accident (14.5%) that consist of 79% total traumatic injuries.Motor to car accident and conflicts were significantly higher in men than women (P<0.004 and P<0.021respectively). The most frequent
injury to one anatomical region was head and neck (23.6%) and thoracic(16.4%) respectively. Head, neck and thoracic injuries were occurred in 46.76% and 39% patientsrespectively alone or with another anatomical region of injuries.Conclusion: Findings of this study indicate that car to a car accident is the most common mechanism oftrauma and on the other hand the most common anatomical region of
injury is head and neck. Individualsin the age group 21-30 are more at the risk of traumatic injuries. By considering the high frequency oftraffic accidents as the leading cause of traumatic injuries, major reforms in traffic and transportationshould be done to improve the structures related to traffic administrations and promoting thetransplantation status.
