Traumatic Liver Injury: Factors Associated with Mortality / 대한구급학회지

ABSTRACT

BACKGROUND: We postulate that a delay in the implementation of hepatic arterial embolization for traumatic liver injury patients will negatively affect patient prognosis. Our work also seeks to identify factors related to the mortality rate among traumatic liver injury patients. METHODS: From January 2008 to April 2014, patients who had been admitted to the emergency room, were subsequently diagnosed with traumatic liver injury, and later underwent hepatic arterial embolization were included in this retrospective study. RESULTS: Of the 149 patients that underwent hepatic arterial embolization, 86 had the procedure due to traumatic liver injury. Excluding the 3 patients that were admitted to the hospital before procedure, the remaining 83 patients were used as subjects for the study. The average time between emergency room arrival and incidence of procedure was 164 min for the survival group and 132 min for the non-survival group; this was not statistically significant (p = 0.170). The average time to intervention was 182 min for the hemodynamically stable group, and 149 min for the hemodynamically unstable group, the latter having a significantly shorter wait time (p = 0.047). Of the factors related to the mortality rate, the odds ratio of the Glasgow Coma Score (GCS) was 18.48 (p < 0.001), and that of albumin level was 0.368 (p = 0.006). CONCLUSIONS: In analyzing the correlation between mortality rate and the time from patient admission to arrival for hepatic arterial embolization, there was no statistical significance observed. Of the factors related to the mortality rate, GCS and albumin level may be used as prognostic factors in traumatic liver injury.
