During the past few months, the novel coronavirus 2019 (COVID-19) pandemic has significantly affected medical service provision. In Iran, it has caused around 197,000 inflictions and 9200 deaths up to June 18, 2020. While many departments turned to telehealth in this era, the trauma service should provide non-stop in presence service to the trauma victims. Our trauma center is the largest in the southwest of Iran, with the mean annual admission of 18,500 polytrauma patients. In this center, we designed a safety protocol to mitigate the spread of disease and also have a more robust case finding system, especially among asymptomatic carriers who attend hospitals based on their trauma. In brief, all unstable patients were considered SARS-COV-2 positive and were directed toward the Specialized COVID-19 related ICU. For all stable patients, history, physical examination, CXR, and lab test (Complete Blood Count, Erythrocyte Sedimentation Rate, C-Reactive Protein) were ordered before entering the wards. If there was any suspicion of COVID-19, the stable patient was admitted to the COVID-19 specialized ward. Among all 1805 patients admitted during a ten weeks interval (from January 30, 2020, to April 14, 2020), 84 had a red flag and toward to COVID-19 related wards. Of those, 67 had positive PCR or evidence in CT in favor of the COOVID-19. Moreover, during regular workups, we found that 19 completely asymptomatic trauma victims had typical Chest CT scan findings of COVID-19.

Objective: To evaluate the accuracy of internal jugular vein waveform to detect early stage of hemorrhagic shockMethods: Forty-three volunteers enrolled in our study between November and December 2018. After blood donation of 450cc, the blood donors in the case group underwent color Doppler sonography of internal Jugular Vein. Besides, the clinical and laboratory indicators of shock were evaluated. The same clinical, laboratory and sonographic data was also obtained from the volunteers in the control group, then Chi-square and Student t-test were applied to make comparison between mentioned groups.Results: After excluding five volunteers, eighteen subjects were included in the blood donor group (mean of age: 35.81±8.05) and 20 healthy volunteers enrolled in the control group (mean of age: 34.95± 6.86). The Jugular pulsatility index was significantly smaller in the case group (0.47 ± 0.27 vs. 0.77 ± 0.52). The jugular pulsatility index above 0.91 excluded blood loss (sensitivity=100%). The combination of clinical, laboratory and sonographic data were also represented as two other indices; Jugular Pulsatility-Shock index and Jugular Pulsatility-Shock-Base Deficit index (JPSBDI). These indices were also accurate enough to detect early blood loss (p=0.011 and <0.001, respectively). JPSBDI below 0.38 was highly accurate to rule out blood loss. (Area under the curve: 0.868, sensitivity=95% and specificity=76.47%).Conclusion: The internal Jugular vein waveform is accurate to detect early stages of shock. The combination of clinical, laboratory and sonographic data is more promising than each of them, separately.

Objective: To evaluate the effect of imbibed fibrinogen gauze on survival, bleeding and healing in liver trauma.Methods: This animal experimental study was conducted on 20 adult male Sprague-Dawley rats; with a mean weight of 300±50 gram; divided into two groups. Grade IV injury was induced to the subjects’ liver. Then, the bleeding site was packed with simple gauze in the control group, and imbibed fibrinogen gauze in the experimental group. All animals were re-evaluated for liver hemostasis 48 hours after the initial injury. Bleeding in the intra peritoneal cavity was measured using Tuberculosis Syringe in the first and second operations. Subjects were followed-up for 14 days. Eventually, the rats were sacrificed and their livers were sent to a lab for stereological assessment. Statistical comparisons were performed via Mann–Whitney U-test using SPSS. P-Values less than 0.05 were considered to be statistically significant.Results: Half of the rats in the control group died, while all the rats in the imbibed fibrinogen gauze group survived after two weeks (p= 0.032). Bleeding in the imbibed fibrinogen gauze was significantly less than control group, 48 hours’ post-surgery (p<0.001). According to the stereological results, granulation tissue in the imbibed fibrinogen gauze group were more than the control group (P= 0.032). Also, fibrosis in the imbibed fibrinogen gauze group were more than the control group (P= 0.014).Conclusion: Our study indicated that imbibed fibrinogen gauze can potentially control liver bleeding and improve survival through increasing granulation tissue and fibrosis in injured liver.

Pneumothorax as a complication of pleural catheter insertion could be very dangerous in patients under mechanical ventilation. In ICU patients, physical examination and supine chest x-ray (CXR) are poorly sensitive in diagnosis of pneumothorax. Moreover, CT scan has also disadvantages, such as radiation, high cost, time consuming and need for patient transfer to radiology suit. In comparison to CXR and CT scan, ultrasonography is an available tool for early and rapid detection of this complication. In this study, we reported a 21-year-old woman, a victim of trauma, undergone pleural catheter insertion for drainage of hemothorax. She developed pneumothorax after the procedure. We discuss the usefulness of ultrasonography after pleural catheter insertion and concluded its adequacy and effectiveness in early diagnosis and also follow-up of pneumothorax.

Objective: To determine the antimicrobial activity and entity of several local herbal plants against Acintobacters isolated from trauma patients admitted to a Level-I trauma center.Methods: The antibacterial activities of the Satureja bachtiarica oil and some selected Iranian medicinal plants (Artemisia sieberi and Tanacetum dumosum belonging to the Asteraceae/Compositae; Salvia mirzayanii and Mentha mozaffarianii belonging to the Lamiaceae/Labiatae) were assayed on A. baumannii by microdilution and agar disc diffusion methods. Having obtained the acceptable antibacterial data, the shade-dried aerial parts of the plants were extracted by hydrodistillation method using Clevenger apparatus according to European pharmacopeia for 3 h. The analysis of S. bachtiarica essential oil accompanied by other herbal drug oils were performed by using GC/FID and GC/MS methods.Results: Outcomes revealed that the S. bachtiarica essential oil exhibited the potent antibacterial capability against Acinetobacter strains in comparison with Colistin, as a positive control. For S. bachtiarica, the growth inhibition zone and minimum inhibitory concentration (MIC) values were 21 mm and 0.5 mg/ml, while, for Colistin, the data were in order: 8 mm and 0.016 mg/ml. Consequently, GC/MS outcomes demonstrated that the major components of the essence were carvacrol (48.6%), followed by p-Cymene (16.6%), γ-terpinene (6.9%) and linalool (5.3%).Conclusion: Based on the considerable inhibitory activity against nosocomial infections by essential oil of S. bachtiarica, it could be considered as the suitable candidate in the food industry and pharmaceutical uses.

Objective: To determine the predictive value of repeated abdominal ultrasonography in patients with multiple trauma and decreased level of consciousness (LOC).Methods: This prospective cross-sectional study was conducted over a six-month period at Shahid Rajaee Trauma Hospital, Shiraz, Iran. We included hemodynamically stable blunt abdominal trauma patients with a decreased LOC (Glasgow Coma Scale ≤ 13) who were referred to the neurosurgery ICU ward. Included cases underwent 1 contrast-enhanced CT scan and two-time ultrasonographic study of the abdomen with an interval of 48 hours. The diagnostic accuracy of the ultrasonography was determined according to the CT-scan results.Results: Overall 80 patients with mean age of 37.75 ± 18.67 years were included. There were 17 (21.3%) women and 63 (78.8%) men among the patients. Compared with the CT-Scan, the first ultrasonography showed a sensitivity of 60%, specificity of 80%, PPV of 16.60%, NPV of 96.80%, and a diagnostic accuracy of 70%. The same values for the second ultrasonographic study were 80%, 79%, 20%, 98%, and 79%, respectively. In 4 (5%) patients whose first ultrasonography and CT scan results were negative, the second ultrasonography was positive for injury.Conclusion: In patients with blunt trauma to the abdomen, when the only indication of abdominal CT scan is a decreased LOC, two ultrasonographic studies can replace a CT imaging.

Clinical databases can be categorized as big data, include large quantities of information about patients and their medical conditions. Analyzing the quantitative and qualitative clinical data in addition with discovering relationships among huge number of samples using data mining techniques could unveil hidden medical knowledge in terms of correlation and association of apparently independent variables. The aim of this research is using predictive algorithm for prediction of trauma patients on admission to hospital to be able to predict the necessary treatment for patients and provided the necessary measures for the trauma patients who are before entering the critical situation. This study provides a review on data mining in clinical medicine. The relevant, recently-published studies of data mining on medical data with a focus on emergency medicine were investigated to tackle pros and cons of such approaches. The results of this study can be used in prediction of trauma patient’s status at six hours after admission to hospital.

Objective: To evaluate the effect of advance trauma life support (ATLS®) training on general surgery residents clinical reasoning skills using the national boards-style objective structured clinical examination (OSCE).Methods: This cross-sectional single-center study was conducted in Shiraz University of Medical Sciences including 51 surgery residents that participated in a mandatory national board style OSCE between May 2014 and May 2015. OSCE scores of two groups of general surgery residents including 23 ATLS® trained and 28 non-ATLS® trained were compared using Mann-Whitney U test. The exam was graded out of 20 points and the passing score was ≥14 including 40% trauma cases.Results: There were 8(15.7%) women and 43(84.3%) men among the participants with mean age of 31.12 ± 2.69 and 33.67 ± 4.39 years in women and men respectively. Overall 7 (87.5%) women and 34 (79.07%) men passed the OSCE. The trauma section OSCE score was significantly higher in the ATLS® trained participants when compared to non-ATLS®(7.79 ± 0.81vs.6.90 ± 1.00; p=0.001). In addition, the total score was also significantly higher in ATLS® trained residents (16.07 ± 1.41 vs. 14.60 ± 1.40; p=0.001). There was no association between gender and ATLS® score (p=0.245) or passing the OSCE (p=0.503).Conclusion: ATLS® training is associated with improved overall OSCE scores of general surgery residents completing the board examinations suggesting a positive transfer of ATLS learned skills to management of simulated surgical patients including trauma cases.

Deep vein thrombosis (DVT) and pulmonary embolism (PTE) are known as venous thromboembolism (VTE). DVT occurs when a thrombus (a blood clot) forms in deep veins of the body, usually in the lower extremities. It can cause swelling or leg pain, but sometimes may occur with no symptoms. Awareness of DVT is the best way to prevent the VTE. Patients with trauma are at increased risk of DVT and subsequent PE because of coagulopathy in patients with multiple trauma, DVT prophylaxis is essential but the VTE prophylaxis strategy is controversial for the trauma patients. The risk factors for VTE includes pelvic and lower extremity fractures, and head injury.

Chest tube (CT) or tube thoracostomy placement is often indicated following traumatic injuries. Premature movement of the chest tube leads to increased hospital complications and costs for patients. Placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. Although there is a general agreement for the placement of a chest tube, there is little consensus on the subsequent management. Chest tube removal in trauma patients increases morbidity and hospital expense if not done at the right time. A review of relevant literature showed that the best answers to some questions about time and decision-making have been long sought. Issues discussed in this manuscript include chest tube removal conditions, the need for chest radiography before and after chest tuberemoval, the need to clamp the chest tube prior to removal, and drainage rate and acceptability prior to removal.

Objective: To explore the pros and cons of early versus delayed intervention when dealing with severe blunt liver injury with significant hemoperitoneum and hemodynamic instability.Methods: This retrospective cross-sectional study was performed at the Nemazi hospital, Shiraz, Southern Iran, level I trauma Center affiliated with Shiraz University of Medical Sciences. The study population comprised of all patients who were operated with the impression of blunt abdominal trauma and confirmed diagnosis of liver trauma during an 8-year period. All data were extracted from patients’ hospital medical records during the study period. The patients’ outcome was compared between those who underwent perihepatic packing or primary surgical repair.Results: Medical records of 76 patients with blunt abdominal liver trauma who underwent surgical intervention were evaluated. Perihepatic packing was performed more in patients who have been transferred to operation room due to unstable hemodynamics (p<0.001) as well as in patients with more than 1000 milliliters of hemoperitoneum based on pre-operative imaging studies (e.g. CT/US) (p=0.002).Conclusion: We recommend that trauma surgeons should approach perihepatic packing earlier in patients who have been developed at least two of these three criteria; unstable hemodynamics, more than 1000 milliliters hemoperitoneum and more than 1600 milliliters of intra-operative estimated blood loss. We believe that considering these criteria will help trauma surgeons to diagnose and treat high risk patients in time so significant hemorrhage (e.g. caused by dilatational coagulopathy, hypothermia and acidosis, etc.) can ultimately be prevented and more lives can be saved.

Objective: To describe the epidemiological characteristics of patients with cervical spine injury admitted to Rajaee hospital, Shiraz, Iran.Methods: This cross-sectional study includes all patients admitted with impression of cervical column injury with or without cervical cord injury from October 2009 to March 2012 to our level I trauma center in Shiraz. We recorded the patients’ characteristics including age, sex, marital status, mechanism of injury, level of injury, concomitant injury, treatment(non-operative or operative) and clinical outcome. The data were described and compared with the international literature.Results: Among 261 patients referred with impression of spinal cord injury, the diagnosis of spinal column injury (with or without spine cord injury) was confirmed in 206 patients. The mean age of patients was 37.2±15.9 years with Male/Female ratio of 3:1. Car turn-over and car-collisions were the leading causes of injury. The most common spine fracture was C6 vertebra involving 60 (29.1%) patients. Fracture of upper and lower extremities were the most concomitant fractures observed in 31(15.1%) patients. Open surgery was performed in 65(31.6%).Mortality rate was 7.3% (15 patients).Patients with brain, lung and cord injuries had increased risk of death, among 15 deaths,9 patients had brain injury, 5 individuals had lung injury and 10 patients suffered from cord injury.Conclusion: Cervical spine injuries mostly affect young males, and comprise 206 (10%) cases out of 2100 spine injuries in our country. Preventive measures should be taken to reduce cervical spine injuries especially in young age group.

Objective: To evaluate the accuracy of surgeons’ intraoperative diagnosis in open appendectomy and compare it with the histopathology examination results afterwards.Methods: This was a cross-sectional retrospective study accomplished in Namazee hospital affiliated with Shiraz University of Medical Sciences, in a one-year period from 2007 to 2008. Medical charts of all the patients who were admitted with impression of acute appendicitis and underwent open appendectomy in our center were included. Demographic information, intraoperative findings as in the operation note based on a method used by our surgeons, and histopathology examination of the removed appendix were recorded and reported.Results: A total of 342 patients were studied including 229 (67%) males and 113 (33%) females, with the mean age of 16.02 ± 9.89 (range 3 to 76) years, with a large proportion from 10 to 15 years. Surgeons reported 97.4% of the patients to have acute appendicitis,29.5%, 10.2% and 5.6% with severe, moderate and mild inflammation pectively, whereas 26.6% and 9.4% with suppurated and gangrenous appendicitis separately, 14.6% to have perforated appendicitis and only 1.5%hadperforated appendicitis with peritonitis. However, 79.5% of cases showed appendicitis in the histopathology review. The accuracy of surgeons’ intraoperative diagnosis is 81.6%, 85.2% for men and 72.6% for women.Conclusion: The method used by our surgeon is not completely indicative in mild to severe inflamed appendix but it is almost always compatible with the pathology results in suppurated, gangrened, and perforated appendix. Therefore surgeons’ gross observation of the inflamed appendix may not always be in concordance with the histopathology examination of the resected appendix.

Objectives: To evaluate the accuracy of sonography in diagnosing acute appendicitis in patients with Alvarado score 4–7.Methods: This is a retrospective cross-sectional study being performed in Namazee hospital affiliated with Shiraz University of Medical sciences during a one year period from 9/2007 to 9/2008. We evaluated all patients with Alvarado score 4-7 and divided them in two groups: those with Ultrasound study prior to surgery and those without any imaging modalities for diagnosis of AA. The demographic information, histopathology, physical examination, laboratory data, sonography report and histopathological reports of patients were gathered. Results: A total of 238 patients had Alvarado scores 4-7 including 160 males and 78 females. 110 patients did not have any imaging and 128 had undergone sonography before operation. Ultrasound had overall sensitivity of 75 %, specificity 69.2 %, PPV 88 %, NPV 46.1% and accuracy of 73.6 %. Negative appendectomy rate was20.9 % and 23.4 % in those without sonography and inpatients with sonography respectively, with a higher rate in females.Conclusion: Ultrasound is more useful when the patient is female and the result of sonography is positive; however, it is not reliable when the result is negative and maybe other diagnostic modalities such as CT scan can help us in better diagnosis of Acute Appendicitis.

Objective: To explain an important aspect of violence, the spatiotemporal pattern of trauma in victims of violence visited in emergency room of Rajaei hospital, Shiraz, IranMethods: This cross-sectional prospective study comprised 109 randomly selected victims of violence visited in emergency room of Rajaei hospital, a tertiary referral hospital affiliated to Shiraz University of Medical Sciences in winter 2013. We recorded the demographic information as well as data regarding the type and time of the injuries. The data collected for each victim was then entered in a data gathering form.Results: The study included 88% males with mean age 27.8 ± 8.8 years, which encompassed more than 60% young adults. Our study showed a temporal pattern with triple peaks. Moreover, 64% of assault trauma occurred at night. Furthermore, our study showed the majority of our patients suffered from stab wounds and about 57% of patients studied lacked high school diploma. Moreover it was revealed that violence was more common in downtown Shiraz, especially in the Fifth city district with simultaneous presence of many risk factors for violence.Conclusion: The result of this study showed that age, gender, educational status and temporal peak of violence were shown to be similar to other investigations conducted in other countries. Despite these similarities, stabbing were more prevalent in our study. Additionally, the Fifth city district of Shiraz seems to be the main city district where preventive intervention is needed to reduce violence- related injuries.
