Effect of exposure to violence on the development of burnout syndrome in ambulance staff

BACKGROUND/AIM The aim of this study is to determine the condition of ambulance staff (AS) who have been exposed to any kind of violence and to predict risk of development of burnout syndrome. MATERIALS AND METHODS Our study was performed with 120 AS working for the Kırıkkale Ambulance Services. During the research, questionnaires collecting descriptive information and the extent of violence to which the AS were exposed were administered; participants were asked to fill out the questionnaire themselves. RESULTS It was found that 81 (67.5%) participants had been subjected to at least one type of violence (verbal or physical). Sixty-two percent were exposed to verbal abuse and 55.8% to verbal threats. Rates of physical threats and attacks were higher among male staff (P = 0.036, P = 0.022), while the rate of personal accomplishment was determined to be significantly lower in males (P = 0.006). Emotional exhaustion and depersonalization scores were determined to be significantly higher in those who perceived less support from administrators (P = 0.014, P = 0.032). CONCLUSION All kinds of negative situations exhaust an individual physically and mentally and lead to the development of burnout syndrome. AS are more prone to these kinds of situations.

Carbon monoxide poisoning cases presenting with non-specific symptoms:

Carbon monoxide (CO) is a colourless and odourless gas appearing as a result of incomplete combustion of carbon-containing fuels. Many domestic or occupational poisonings are caused by CO exposure. Malfunctioning heating systems, improperly ventilated motor vehicles, generators, grills, stoves and residential fires may be listed in the common sources of CO exposure. The aim of this study was to emphasize the significance of early diagnosis of CO poisoning with non-invasive measurement of CO levels of the patients with non-specific symptoms using a pulse oximeter device in the triage. Our study was a cross-sectional study. Patients who presented to the emergency department (ED) due to non-specific symptoms and had a Canadian Triage and Acuity scale level of 4 or 5 were included in the study; 106 (5.9%) of 1788 patients admitted during the study period were diagnosed with CO poisoning. Patients with CO poisoning and the other patients had statistically significant differences in terms of presenting symptoms, namely, headache, dizziness, nausea, and vomiting. More CO poisoning cases were admitted in the fall and winter compared to the spring and summer. The number of CO poisoning victims can be decreased if preventive measures like CO monitoring systems and well-designed ventilation systems are generalized at homes and workplaces. Measurement of carboxyhaemoglobin levels of patients presenting to ED due to non-specific symptoms like headache and dizziness during cold seasons and winter months using a pulse CO-oximeter should be a part of the routine of emergency medicine triage.

A study to develop clinical decision rules for the use of radiography in wrist trauma: Karadeniz wrist rules.

INTRODUCTION The aim of this study was to evaluate patients presenting to the emergency department (ED) with wrist trauma using physical examination findings and functional tests and to identify findings with high sensitivity and specificity among the parameters assessed in patients with fracture in the wrist. The ultimate objective was thus to establish a reliable and widely usable clinical decision rule for determining the necessity of radiography in wrist trauma. METHODS This prospective, multicenter study was performed in 8 hospitals. The relation between radiologically determined fracture and clinical findings consisting of physical examination findings and functional tests was assessed in terms of whether or not these were markers of radiography requirement, with the aim of identifying predictive values for fracture. RESULTS A total of 603 eligible trauma patients presented to the participating EDs during the study period. Fracture was identified in 24.5% of patients (n = 148). The 4-way combination with the highest sensitivity was identified as axial compression and the positive distal radioulnar drawer test, and pain with radial deviation and dorsal flexion. Sensitivity at distal ulna palpation was added as a fifth parameter, and sensitivity and negative predictive value thus increased to 100%. CONCLUSION With their 100% sensitivity and 100% negative predictive values, the Karadeniz wrist rules may represent a clinical decision rule that can be used in practice in EDs. If all 5 findings are negative, there is no indication for wrist radiography.

Determination of radiography requirement in wrist trauma

OBJECTIVES The purpose of this study was to evaluate predetermined physical examination and function tests recommended to identify severe injury among patients presenting with wrist injury to the emergency department and to establish a reliable clinical decision rule capable of determining the need for radiography in wrist injuries. MATERIALS AND METHODS This was a multicenter prospective derivation study of wrist injuries. All patients were assessed in terms of mechanism of trauma, inspection findings, heart rate, sensitivity at palpation, presence of pain with active movement, grasp strength, and functional tests using an examination form under main headings. Sensitivity, specificity, and positive and negative predictive values were expressed for each sign and each examination finding. RESULTS One hundred nineteen adult patients were enrolled during the 6-month study period. Fracture was identified in 24.3% (n = 29). Presence of pain on the radial deviation, dorsal flexion, distal radioulnar drawer, and axial compression tests exhibited high sensitivity (82.8%, 89.7%, 82.8%, and 86.2%, respectively) and high negative predictive values (88.6%, 81.3%, 87.5%, and 93.6%, respectively) for wrist fracture. Sensitivity of 96.6% was observed when these 4 tests were evaluated together. CONCLUSIONS The presence of one of these examination findings increases the likelihood of fracture and is adequate to recommend wrist radiography. In addition, there is a strong possibility of radiography being unnecessary if all 4 test results are negative in patients presenting with wrist injury, potentially preventing many nonessential radiographs being performed.

Effect of hypothermia on apoptosis in traumatic brain injury and hemorrhagic shock model

INTRODUCTION The neuroprotective mechanisms of therapeutic hypothermia against trauma-related injury have not been fully understood yet. In this study, we aimed to investigate the effects of therapeutic hypothermia on biochemical and histopathological markers of apoptosis using Traumatic brain injury (TBI) and hemorrhagic shock (HS) model. METHODS A total of 50 male albino-wistar rats were divided into five groups: Group isolated TBI, Group NT (HT+HS+normothermia), Group MH (HT+HS+mild hypothermia), Group MoH (HT+HS+moderate hypothermia) and Group C (control). Neurological deficit scores were assessed at baseline and at 24h. The rats were, then, sacrificed to collect serum and brain tissue samples. Levels of Caspase-3,6,8, proteoglycan-4 (PG-4), malondialdehyde (MDA), and nitric oxide (NO) were measured in serum and brain tissue samples. Histopathological examination was performed in brain tissue. RESULTS There were significant differences in the serum levels of Caspase-3 between Group NT and Group C (p=0.018). The serum levels of Caspase-6 in Group NT (0.70±0.58) were lower than Group MH (1.39±0.28), although the difference was not statistically significant (p=0.068). There were significant differences in the brain tissue samples for Caspase-3 levels between Group NT and Group C (p=0.049). A significant difference in the Caspase-8 brain tissue levels was also observed between Group NT and Group C (p=0.022). Group NT had significantly higher scores of all the pathological variables (for edema p<0.017; for gliosis p<0.001; for congestion p<0.003, for hemorrhage p<0.011) than Group C. CONCLUSION Our study results suggest that hypothermia may exert its neuroprotective effects by reducing markers of apoptotic pathway, particularly Caspase-3 on TBI and HS.

Osborn wave in hypothermia and relation to mortality

BACKGROUND & AIM The aim of this study was to compare hypothermia patients with and without an Osborn wave (OW) in terms of physical examination findings, laboratory results, and clinical survival. METHODS The study was carried out retrospectively on hypothermic patients. The hypothermic patients were divided into two groups. Group 1 comprised patients with OW on electrocardiogram (ECG), and Group 2 comprised patients without OW on ECG. The Mann-Whitney U test was used to compare the two groups, and the relationships between the variables and the presence of OW and mortality were analyzed with ANOVA. A value of p < 0.05 was considered statistically significant. RESULTS OW was detected on ECG of 41.9% of the patients (Group 1). The mean body temperature was 30.8 ± 4.1 °C in Group 1 and 33.3 ± 1.6 °C in Group 2 (p = 0.106). The mean creatinine level was 1.01 ± 0.6 mg/dl in Group 1 and 0.73 ± 0.5 mg/dl in Group 2 (p = 0.046). The mean bicarbonate level was 15.9 ± 3.8 mmol/l in Group 1 and 18.6 ± 3.5 mmol/l in Group 2 (p = 0.038). A relationship was determined between the presence of OW and pH, bicarbonate, and creatinine levels (p = 0.026; 0.013; 0.042, respectively). The mortality rate was 69.2% in Group 1 and 77.8% in Group 2 (p = 0.689). CONCLUSION Although there is a relationship between the decrease in bicarbonate levels, changes in kidney functions that cause acidosis, and the presence of OW, it has no effect on mortality. The presence of OW in hypothermic patients is insufficient to make a decision regarding mortality.
