“…The DSM V undoubtedly underestimate the prevalence of actual trauma in the general population, because it does not identify events that aren't life-threatening, for example, excessive emotional abuse, significant loss or separation, humiliation or humiliation, sexual experience with compulsion (not physical violence) as trauma. In addition, the criteria for post-traumatic stress disorder (Brewin & Holmes, 2003) and the diagnosis of acute stress disorder (Horowitz, Wilner, & Alvarez, 1979) are prerequisites, some people who suffer from significant post-traumatic stress are less likely to be diagnosed with stress disorder (Baysak, 2010;Briere & Scott, 2016;Cohen & Murch, 1996).…”

“…Among the most frequent traumatic events they face include encountering people exposed to man-made attacks, such as child deaths, social disasters, rape and torture, seeing a dead body or body part, removing the fragmented limbs or corpses from the crash site. It is also easier for healthcare personnel, who witness traumatic incidents while they response to such problems, that they experience problems such as acute stress disorder, posttraumatic stress disorder, major depression, psychosomatic disorders and substance use disorder (Baysak, 2010;Erkaya, 2003).…”

Traumatic incidents are defined as despair people are in when they face fears, weaknesses and vulnerabilities. The purpose of the present research is determining the mental problems faced by emergency health workers while performing their jobs and how they deal with these problems. For this purpose, “The Hopelessness Scale, Locus of Control Scale, Problem Solving Inventory, Multidimensional Scale of Perceived Social Support, Post Traumatic Growth Inventory, Peritraumatic Dissociative Experiences Questionnaire, The Posttraumatic Diagnostic Scale and Beck Depression Inventory were used as data collection tools. The present research was designed in accordance with general screening model, which is a descriptive research method. With this model, how the independent variable affected the dependent variable was investigated and the regression analysis was conducted for the relationship between the variables. The research was carried out on the employees of the Department of Emergency Health Services in Erzincan and data were collected from 400 emergency health workers. The statistical analysis of the data was done by SPSS 20.00 package program and .05 was taken as the significance level. According to the regression analysis results hopelessness, negative effects of events on life, social support and dissociation were significantly related with stress symptoms and depressive mood levels. It was found that the effects of event and dissociation predict posttraumatic stress symptoms positively; and social support negatively. It was observed that hopelessness and post-traumatic stress symptoms predicted the level of depression positively and social support negatively. According to the findings of the research, it was recommended that psychosocial support units may be useful in emergency health services and psycho-education and psychological counseling services provided by the psychosocial unit can be useful for the stress, posttraumatic stress disorder and other problems that may be experienced.

“…A decrease in cerebral perfusion pressure has an obvious effect on the Doppler waveform, with typical changes that include a decreased diastolic blood ow velocity [16]. When cerebral circulation stops, and intracranial pressure starts to increase for whatever reason, there is a decrease in end-diastolic blood ow velocity on TCD [24]. A modest increase in VD as opposed to VS was associated with complete recanalization/reperfusion, early neurological improvement, and a favorable functional outcome, suggesting that augmentation of diastolic ow may represent a novel therapeutic reperfusion target [25].…”

Background: Posterior circulation cerebral infarction (PCCI) leads to decreased cerebral blood flow (CBF) and metabolism. Neural activity is closely related to regional CBF both spatially and temporally. Transcranial Doppler (TCD) combined with quantitative electroencephalography (QEEG) can evaluate neurovascular coupling and involves synergy between the metabolic and vascular systems. This study aimed to monitor brain function using TCD-QEEG and estimate its efficacy in predicting the prognosis of patients with PCCI.Methods: We used TCD-QEEG to perform quantitative brain function monitoring; we recorded the related clinical variables simultaneously. The data were analyzed using a Cox proportional hazards regression model. Receiver-operating characteristic (ROC) curve analysis was used to evaluate the cut-off for the diastolic flow velocity (VD) and (delta+theta)/(alpha+beta) ratio (DTABR). The area under the ROC curve (AUROC) was calculated to assess the predictive validity of the study variables. Results: Forty patients (aged 63.7±9.9 years; 30 men) were assessed. Mortality at 90 days was 40%. The TCD indicators of VD (hazards ratio [HR] 0.168, confidence interval [CI] 0.047–0.597, p=0.006), and QEEG indicators of DTABR (HR 12.527, CI 1.637–95.846, p=0.015) were the independent predictors of the clinical outcomes. The AUROC after the combination of VD and DTABR was 0.896 and showed better predictive accuracy than the Glasgow Coma Scale score (0.75), VD (0.76), and DTABR (0.781; all p<0.05).Conclusion: TCD-QEEG provides a good understanding of the coupling mechanisms in the brain and can improve our ability to predict the prognosis of patients with PCCI.

“…There are many inconveniences in clinical application, which limit these methods as routine examination methods. Electroencephalogram (EEG) can continuously monitor patients with craniocerebral injury, but EEG detection is based on EEG resting as the diagnostic criteria of brain death, and there are still many problems in EEG resting as the diagnostic criteria, which has been controversial in clinical practice ( Kasapoglu et al, 2019 ). In recent years, some scholars have found that not all patients with clinical brain death have EEG resting state, but some patients have extensive EEG activities.…”

Objectives To investigate the clinical value of non-invasive ultrasound imaging in the evaluation of brain death caused by traumatic brain injury. Methods Thirty-four patients with acute severe traumatic brain injury were admitted to hospital within 48 h after injury. All patients were monitored intracranial pressure, transcranial Doppler, echocardiography examination, collection intracranial pressure, MCA-Vs, MCA-Vd, MCA-Vm, EF, LVMPI, RVMPI and other indicators, and combined with clinical conditions and other related data for comparative study and statistical analysis. Results The blood flow spectrum was characterized by diastolic retrograde blood flow spectrum pattern and nail waveform spectrum shape when the patient had clinical brain death. For the parameters of transcranial Doppler, there were significant differences in MCA-Vm and PI between clinical brain death group and normal control group ( P < 0.05). For the parameters of echocardiography, there were statistically significant differences in EF, LVMPI, and RVMPI between clinical brain death group and normal control group ( P < 0.05). Conclusion Non-invasive dynamic monitoring of cerebral hemodynamics and cardiac function parameters in patients with severe craniocerebral injury can provide a high accuracy and reliability for the preliminary diagnosis of brain death in patients with severe craniocerebral injury. It is helpful for early evaluation of prognosis and provides effective monitoring methods and guidance for clinical treatment.
