Abstract

BACKGROUNDS: Blast injuries have a variety of mechanisms, with some cases resulting in immediate death and others resulting in burns as a fourth type of blast injury when the energy of the explosion is relatively low. We reported in 2020, as an incidental result, that burns caused by explosions had a higher survival rate than usual burns caused by other mechanisms. The present study confirmed whether or not burns caused by explosions had higher survival rates than those caused by other mechanisms using the Japan Trauma Data Bank (JTDB), a leading nationwide trauma registry in Japan.

METHODS: Burn patients registered to the JTDB database from January 2004 to March 2019 were analyzed retrospectively. The 338,744 patients registered to the JTDB database published in 2021 were identified. After exclusion, 7127 patients met the criteria for inclusion in this study. Logistic regression analyses were conducted for in-hospital survival rates using patients with burns, including cases complicated by usual trauma and burned patients without usual trauma. The survival rates by External burn grade AIS98 were compared between the explosion group and other cause groups using burn cases without usual trauma.

RESULTS: The cause of the explosion significantly influenced the survival according to logistic regression analyses using burn groups with and without usual trauma. For AIS 4 and 5, we found significant differences between the explosion group and other cause groups in survival rates among burn cases without usual trauma.

CONCLUSION: The survival rate of patients with burns induced by explosions was higher than that of common burn cases according to analyses based on a burn grade of AIS98 among burn cases without common trauma. Multivariate analyses also showed that explosion burns had a significantly better outcome than those induced by other causes.
