is a common medical problem for critically ill patients. Blood transfusion
to augment oxygen delivery for these patients has been a traditional therapy. However, few studies have identified the impact of anemia
on individuals suffering from severe traumatic brain injury
(TBI). Hence, this study aims to evaluate the effects of initial anemia
on patients with severe TBI admitted to the Emergency Unit.
We reviewed the medical records of patients with isolated severe TBI admitted to the Emergency Unit of a university hospital from July 2003 to June 2008. Patients were divided into two groups based on their initial anemia
data taken while in the Emergency Unit. The anemia
datum is defined as hemoglobin (Hb) <10 mg/dL. The t
test was used to identify the differences between the two groups, while logistic regression was applied to determine any significant differences found in the statistical analysis.
A total of 234 patients were signed up in our study. Based on their initial hemoglobin at emergency department
, 23 patients (9.8%) comprised the anemia
group, 17 patients (7.3%) comprised the nonanemia group, whereas 112 patients (47.9%) belonging to the nonanemia group were deceased. There is no significant difference between the two groups (p
= 0.076; odds ratio, 0.97; confidence interval, 0.78–1.05).
This study shows that initial anemia
is not a mortality risk factor for patients with isolated severe blunt TBI.
