Clinical Manifestations and Effects of In-Hospital Resuscitative Procedures in Patients with Traumatic Out-of-Hospital Cardiac Arrest from Three Hospitals in Southern Taiwan.

BACKGROUND: The prognosis of patients with traumatic out-of-hospital cardiac arrest (TOHCA) is poor. Few studies have evaluated whether the commonly conducted in-hospital resuscitative interventions have beneficial effects on the return of spontaneous circulation (ROSC) and survival rate in patients with TOHCA. Therefore, we conducted a retrospective study to reveal the clinical manifestations of patients with TOHCA in Southern Taiwan and evaluate the effectiveness of variouscommon in-hospital interventions in these patients.

METHODS: This retrospective chart review of patients with TOHCA was conducted in three hospitals in Southern Taiwan between January 1, 2014, and December 31, 2016, to demonstrate the characteristics of patients with TOHCA and compare the differences in in-hospital interventions before ROSC between ROSC and non-ROSC groups.

RESULTS: In total, 272 patients with TOHCA were reviewed; their average age was 50.7 years, and men constituted the predominant sex (73.2%). Moreover, 91 patients (33.5%) experienced at least transient ROSC, 40 patients (14.7%) were admitted to hospitals, and 4 patients (1.5%) survived to hospital discharge. The ROSC and non-ROSC groups did not differ in in-hospital interventions, including chest tube and central venous catheter insertions, defibrillation, and pressor infusion. However, the non-ROSC group had a higher rate of transfusion than the ROSC group (17.7% vs. 6.6%, p = 0.015).

CONCLUSION: The outcomes of patients with TOHCA in Southern Taiwan remained dismal. None of the in-hospital interventions, including blood transfusion, chest tube and central venous catheter insertions, defibrillation, and pressor infusion, were determined to be beneficial for patients with TOHCA. We suggest that these in-hospital interventions should not be routinely performed in every patient with TOHCA.
