The aim of our study was to evaluate the effect of lactate level (LL) and shock index (SI) on the outcome in nontraumatic hypotensive patients in the emergency department, and also to show the significance of the combined usage of these two parameters. This is a prospective, observational study. Elevated and normal LL (ELL and NLL), elevated and normal SI (ESI and NSI), and a combination of these two parameters (lactate-SI group 1: ELL and ESI, lactate-SI group 2: ELL or ESI, and lactate-SI group 3: NLL and NSI) were evaluated for primary (mortality) and secondary outcome measures. A total of 131 patients who fulfilled the inclusion criteria were analysed. Of the patients with ELL, 34.78% were mechanically ventilated (P0.05). In-hospital mortality in lactate-SI group 1 was higher (54.1%, P<0.0001, sensitivity: 100.0%, NPV: 100.0%). The combination of both parameters is effective in predicting these outcome measures with higher sensitivities and NPVs. Further studies on the subject are required.

We aimed to define factors predicting mortality in patients having ST elevation myocardial infarction (STEMI) who had Primary Percutaneous Coronary Intervention (PCI) in our setting. This is a prospective study on patients presenting to the emergency department with STEMI who underwent PCI during a 12-month period. Physiological parameters were calculated using the vital signs and age of patients. Time-based factors in the institutional protocol were collected. Univariate analysis was performed to define significant factors that affected mortality. Significant factors were then entered into a logistic regression model. Factors significantly affecting mortality were defined. Receiving operating characteristic curve was applied to define the best predictors of mortality. A total of 167 consecutive patients were studied; 128 (76.6%) were males. The mean (SD) age of the patients was 61.9 (12.8) years. The logistic regression model showed that significant factors were age (P = .002), Modified Shock Index, MSI (P = .028), systolic blood pressure (P = .028), and time between consultation and activation of catheter laboratory (P = .047). The cut-off points with best prediction of mortality were age of 71.5 years, systolic blood pressure of less than 95 mmHg, MSI of 0.85, and a time more than 3.5 minutes between consultation and activation of catheter laboratory. Our study shows that significant predictors of 30-days mortality of STEMI were age, systolic blood pressure on presentation, MSI, and the time between consultation and catheter laboratory activation. Improving prehospital resuscitation and activation of the catheter laboratory by emergency physicians may reduce mortality in our setting.

To evaluate the association of inherited coagulopathies and acquired conditions (e.g. hypertension, aspirin use) with emergency department admission due to epistaxis. Patients admitted to the emergency department with epistaxis were included. A questionnaire for personal and family history of any bleeding disorder was used. Physical examination including ear, nose and throat examination was performed. Platelet counts, International Normalized Ratio, activated partial thromboplastin time, factors VIII, IX and XI, von Willebrand factor and ristocetin cofactor activity levels were determined. Nineteen patients were included in the study. Personal history of mucocutaneous bleeding was present in four cases and family history in two cases. Only one case (5%) had a decreased von Willebrand factor level (45%), and also had a personal and family history of bleeding tendency. Ten patients (53%) had a history of aspirin use. Thirteen (68%) patients had hypertensive values on admission. Aspirin use and hypertension were the leading causes of emergency service admission in adults due to epistaxis in this study, although the number of the patients was relatively low. Regarding the low prevalence of inherited coagulopathies, detailed coagulation tests should be reserved for adult patients with positive personal and/or family history of bleeding.
