BackgroundTrauma, in addition to economic and social costs, is the fourth cause of death in the world and in the year 2000 alone, it led to the death of more than 6000000 people. In Iran, Trauma has the first burden of disease and also needs a long medical surveillance.ObjectivesThe aim of this study was to evaluate the outcome of trauma cases using the trauma score and the injury severity score (TRISS) model and then comparing this with the results of a major trauma outcome study (MTOS) carried out in the US.Patients and MethodsThis study is a retrospective, descriptive and analytical study on 1000 patients aged 2 - 82 years old with closed or penetrating traumas staying at Ardebil Fatemi hospital. In this study, injury severity score (ISS), revised trauma score (RTS), and TRISS were calculated and patients' viability ratios were obtained.ResultsThe results showed that 714 patients (71.4%) were male and 286 patients (28.6%) female with the mean age of 35.68 years. In this study 45 (4.5%) and 955 patients (95.5%) had penetrating and blunt traumas, respectively, whereby the head and neck were the most prevalent (74%) areas of injury. The most common reason for these traumas was, accident with vehicles with 670 cases (67%), which resulted in hospitalization. From this group, ninety-seven cases (9.7%) died in the hospital. From these results, calculations of ISS and RTS were 15.50 ± 11.31 and 7.49 ± 0.79, respectively. According to the calculation of the TRISS model, 91.5% of trauma victims should be survived, while only 90.3% survived practically.ConclusionsWe can conclude that the surveillance presented to our injured group probably had some defects that need to be revised in therapeutic services to enhance survival requirements.

Background: Cardiovascular disease is one of the most common causes of mortality in developed countries, as well as in the whole world. In this regard, autologous transfusion is a topic that can be useful and valuable, especially in complex surgery such as heart surgery and organ transplantation. One of its variants is Acute Normovolomic Hemodilution (ANH). Therefore, the aim of this study was to compare the effect of ANH on the amount of bleeding in the first 48hours after coronary artery bypass grafting.Methods: In this clinical trial, 100 patients were selected from all heart patients referred to Imam Khomeini Hospital in Ardebil for CABG surgery in the years 2016-17. They were selected by simple random sampling as a statistical sample and They were divided into intervention (50 ANH recipients’ people) and control groups (50 without ANH people).Results: Based on the findings, in the ANH recipients’ group, the mean of bleeding volume was 59.1±7.3ml in the first day and 55.6±4.2ml in the control group and the difference between the two groups was not significant on the first day. The mean of bleeding volume on the second day was 46.1±2.8ml in the ANH group and 42.7±2.9ml in the control group. Although it was somewhat higher, it was not statistically significant. Of all samples 45% were female and 55% were male. The most common type of blood group was 33 (33%) in the blood group O. The highest age group (61%) was over the 60 years old. The pump time varied with an average of 122.2±21.5minutes. The lowest value was PT 11 and the highest was 15 with an average of 13.02±0.9seconds. The mean of PTT was 32.5±2.6seconds and the mean INR was 1.1±1.0. The average plt was 251170±64124. The mean ACT was 596 / 6±183/7seconds.Conclusions: The results showed that in the mean of bleeding volume between the intervention and control groups (p = 0.41), bleeding volume by age (p = 0.3), bleeding volume by gender (p =0.54) and bleeding volume by blood group (p=0.48) was not significant difference. Based on these results, it is suggested that more studies be done on the more number of samples.

Background: Several studies have shown that approximately 95% of patients who have been admitted to the ICU are anemic. Anemia in acute patients leads to significant transfusion. Transfusion can lead to significant complications. Because of the risks of transfusion an alternative therapy for anemia in patients seems be a necessary need for its. The aim of this study was to investigate the efficacy of Erythropoietin in treatment of anemia in patients hospitalized in the ICU of Ardabil city hospital.Methods: This study is a clinical trial. In this study after selection of patients based on inclusion and exclusion criteria, their data were entered in a check list. Patients were divided into two groups of 35 persons randomly. For first group, erythropoietin was administrated in addition of iron and in second group only iron was administrated. All patients were administrated 100 mg of iron. Hematological indexes and clinical status of patients was evaluated and results were analyzed by statistical methods in SPSS version 19.Results: In this study, in cases 65.7% and in controls 71.4% were male. The average age of patients in cases was 61.6±20.8 and controls were 61.02±22.5 years. The mean duration of hospitalization in internal ICU was 37.73 days and in surgical ICU was 21.35 days and was observed that at baseline the hemoglobin levels in internal patients was lower than surgical patients (p=0.023). 80% of patients in case group (5.8 units) and 88.57% of patients in controls (6.3 units) required blood transfusion. The hemoglobin level in erythropoietin receiving group increased significantly compared to the control group.Conclusions: The results of this study showed that erythropoietin is an effective drug to increase hemoglobin level and can provide a significant increase in hemoglobin level compared to placebo.

<p class="abstract"><strong>Background:</strong> VO₂/VCO₂ ratio and blood lactate are different indices of adequacy of oxygen delivery to oxygen needs. The aim of this study was to investigate the relationship between serum lactate and VO₂/VCO₂ in patients undergoing CABG in Ardabil city.</p><p class="abstract"><strong>Methods:</strong> This descriptive-analytical study was performed on 30 patients who underwent CABG at Ardabil city hospital during 2017. Demographic data of patients including age and sex were collected. Standard monitoring included electrocardiogram, invasive arterial pressure, pulse oximetry, end tidal carbon dioxide, temperature and urine output was done. The CAB was carried out through a CPB pump at the time of grafting. Blood lactate and VO₂/VCO₂ were measured in 3 groups of patients based on number of grafts, EF and serum Creatinine.
