Background and Objectives Blood transfusion is a major challenge in treating trauma patients. This study investigated blood transfusion rates and related factors in trauma patients. Materials and Methods This retrospective cross-sectional study analyzed 849 trauma patients admitted to a trauma center in Shiraz, Iran during 2019-2021. Blood components usage and its relation to demographics, clinical status, lab values, and ABC score were assessed. The frequency of massive blood transfusion and the average number of blood units and blood components consumed in these patients were surveyed. Data were analyzed by T-test, Chi-squared test, and logistic regression with SPSS-23. Results The mean age was 38.6 ± 19.40 years and 80.9% were male. The mean blood units, platelets, and plasma used were 5.74 ± 4.57, 1.21 ± 4.87, 2.73 ± 4.32, respectively. 62.01% received massive transfusion with mean blood, platelets, and plasma units used being 8.17 ± 5.21, 3.92 ± 4.88 and 1.85 ± 6.01, respectively. Blood use correlated with systolic/diastolic pressures, blood sugar, lymphocyte count, pH, bicarbonate, base deficit, and hematocrit. 13.3% had positive ABC score and received more blood products (p < 0.001). Conclusions Blood transfusion in trauma patients depends on various clinical and lab factors. Identifying high-risk patients requiring urgent blood transfusion and rapid preparation of blood products is vital for optimizing trauma patient management and outcome. [ABSTRACT FROM AUTHOR]

Background and Objective: Trauma is the most common cause of death in all individuals between 1 and 44 years and the third most common cause of death regardless of age. The abdomen is the third most commonly injured region of the body. Some intra abdominal organ injured more than others, related to mechanism of injury, size and location of organ in abdominal cavity. This study was carried out to determine the prevalence of intra abdominal injuries due to penetrating trauma. Materials and Methods: This retrospective descriptive study was done on 114 patients admitted to 5 Azar hospital in Gorgan, Iran due to penetrating abdominal trauma during 2002-07. Gender, age, type of injury causes of trauma and hospitlalization period were obtained form patients files. Results: 92.1% of patients were male. The mean age of subjects was 24.8 years (9-70 years) with highest frequency between 20-24 years. Two (1.8%) deaths directly related to abdominal stab wounds related to hemorrhagic shock. The most common cause of penetrating abdominal injury was knife wound (78.9%). The mean time spent in hospital was 4.6±2.8 days. In 53 patients, cause of trauma were either related to pentration into peritoneum or passing through in. Small intestine injuries (14 %), rupture of diaphragm and concurrent lung injuries (7%) were the common damage organs. Conclusion: This study showed that the knife was the main cause of abdominal penetrate trauma and peritoneum was the most common damage tissue. [ABSTRACT FROM AUTHOR]
