Autoregulation disturbance events correlate with history of loss of consciousness in mild traumatic brain injury patients

Introduction: Cerebral autoregulation disturbance may compromise cerebral blood flow, thereby increasing the risk of hypoperfusion, which increases loss consciousness (LOC). Transient hyperemic response test (THRT) using transcranial Doppler (TCD) can be used to assess disturbance. The goal this study was relationship between impaired assessed TCD and a history LOC in patients with mild head injury. Patients Methods: This comparative analytic unpaired data cross-sectional design that involved 73 people divided into two groups. Group A (36 subjects) consists brain injury LOC, B (37 without LOC. THRT by identifying absence (negative result) flow velocity increase upon applying pressure on ipsilateral carotid artery. We employed chi-square logistic regression tests any correlation variables. value P < 0.05 considered significant. Results: Approximately 93% subjects who experienced also showed negative results. found statistically significant (P 0.001) THRT. In test, we age, gender, hematocrit were not related Conclusion: There is decreased event patients.
