Initial Factors Affecting 6-month Outcome of Patients Undergoing Surgery for Acute Post-traumatic Subdural and Epidural Hematoma

Abstract

Introduction: The most frequent consequences of a traumatic brain injury are acute subdural (SDH) and epidural hematoma (EDH), which usually require a surgical treatment. Most of the factors affecting the prognosis have been analyzed on a wide group of traumatic brain injuries. Nonetheless, there are few studies analyzing factors influencing the prognosis regarding patients with EDH and SDH. The aim of the study is to identify factors which have prognostic value in relation to 6-month outcome of patients undergoing surgery for acute hematoma. Patients and methods: The study included a group of 128 patients with isolated craniocerebral injuries. The patients were divided into two groups, namely a group of 28 patients operated on due to epidural hematoma and a group of 100 patients operated on due to acute subdural hematoma. All patients were operated and treated in the Department of Neurosurgery at the Medical University in Lublin from 1.10.2014 to 31.08.2017. The following factors from the groups were analyzed: demographic data, physiological factors, laboratory factors, computed tomography scan characteristics, and time between the trauma and the surgery. All the factors were correlated with six-month outcome in Glasgow outcome scale. Results: The univariate analysis has confirmed the influence of many factors affecting the outcomes. Conclusion: It is interesting that the factors such as GSC score, saturation, respiratory rate, and systolic blood pressure were associated with outcome with highly statistically significant differences in both group. These are factors that, with an appropriate treatment, could be normalized at the place of the accident.
