Objective:To evaluate the prognostic value of arterial blood gas (ABG) indices, especially base excess (BE), regarding the severity of traumatic injury.Methods:A total number of 96 trauma patients with fractures of femur and pelvis were included in this study. Demographic characteristics and clinical information of samples were recorded. The results of ABG test and hemoglobin (Hb) were evaluated at two time intervals (on admission and 6 hours later). The outcome of the patients was evaluated at the end of the study (dead or alive). The ABG indices included O2 saturation (O2Sat), PH, PO2, PCO2, bicarbonate (HCO3) and base excess (BE). The mean of the hemodynamic and ABG indices were compared between those who were discharged and mortality cases. The confounders were compensated using a multivariate logistic regression model. Results:Overall 94 trauma patients with long and pelvic fractures were included. There were 69 (73.4%) men and 25 (26.6%) women among the patients with mean age of 37.43 ± 20.07 years. The mortality rate was 10 (10.6%). The most common mechanism of injury was motorcycle accident in 41 (43.6%) and car collision in 43 (45.7%) patients. We found that mortality was significantly associated with amount of FFP transfusion (p=0.005), but was not associated with amount of transfused packed cells (p=0.113). We also found that mortality was associated with lower BP after 6 hours of admission (p=0.001), higher HR on admission (p=0.036), lower HR after 6 hours (p=0.017), lower O2Sat on admission (p<0.001), higher PCO2 after 6 hours and lower BE on admission (p=0.025). Conclusion: The ABG indices including O2Sat, BE and PCO2 are considered prognostic determinants of outcome in trauma patients with long and pelvic fractures. These findings can be considered as fundamental studies to achieve new diagnostic methods.
Introduction: One of the largest religious gatherings in the world is the Arbaeen pilgrimage, which takes place on the 40th day after the anniversary of the martyrdom of Imam Hussein, the third Shiite Imam. This study was aimed to investigate how to set up the Sahib-al-Zaman treatment camp on the Arbaeen walking route in 2019 and the patients referring to it. Methods: This retrospective cross-sectional study was conducted on all patients referring to the Sahib-al-Zaman camp of Shiraz University of Medical Sciences, Shiraz, Iran in the Arbaeen Walking plan in 2019. In this study, how to set up camp was described. Patients’ data and drugs used by the medical team were collected, and then were analyzed. Results: Totally, 3477 patients were enrolled. The mean±SD of patients’ age was 33.77±16.19 (ranging from 1 to 96) years, and 2,183 patients (62.78%) were male. Most patients were Iranian (84.5%) and then Iraqi (13.66%), and only 1.84% were from other nationalities. Upper respiratory tract infection (60.2%), low back pain and muscle cramps (17.6%), and blister and need for dressing (12.3%) were the most common chief complaints in the patients. Adult cold pills, acetaminophen (325 mg), and cetirizine (10 mg) were the most commonly prescribed drugs for the patients. Conclusion: Although the data used in this study are not sufficient due to the lack of a pre-created data recording system, the results of this study showed that in addition to the importance and necessity of holding such ceremonies, health issues and facilities should also be considered.
