The clinical value of enhanced whole-body CT in the early treatment of severe trauma / 中华急诊医学杂志

ABSTRACT

Objective:To investigate the significant effects of enhanced whole-body computed tomography (EWBCT) and non-enhanced whole-body computed tomography (N-EWBCT) on the missed diagnosis rate, renal function and prognosis of patients with severe trauma.Methods:Clinical data of trauma patients admitted from January 1, 2017 to December 31, 2020 were collected from the trauma database of the Trauma Center of the Second Affiliated Hospital of Soochow University. All patients included in this study were divided into the EWBCT group and N-EWBCT group according to whether they underwent enhanced whole-body computed tomography examination. The differences in baseline data, missed diagnosis rate, renal function and prognosis of the two groups of patients were compared.Results:A total of 459 patients were included in this study, including 184 patients in the EWBCT group and 275 patients in the N-EWBCT group. The missed diagnosis rate of the N-EWBCT group was significantly higher than that of the EWBCT group (18% vs. 5%, P < 0.01). The risk ratio of acute kidney injury (AKI) in the EWBCT group and N-EWBCT group was 9% and 7%, respectively, and there was no statistical difference between the two groups ( P >0.05). The mortality rate of patients in the N-EWBCT group was higher than that in the EWBCT group (23% vs. 12%, P=0.002). Conclusions:Compared with N-EWBCT, EWBCT does not significantly increase the risk of renal damage in patients with severe trauma. For patients with severe trauma, early EWBCT can reduce the missed diagnosis rate and improve the clinical prognosis.
