Objective: Ultrasound assessment of inferior vena cava (IVC) collapsibility is performed todetermine the volume status of critically ill patients. We propose a new acoustic windowfor visualizing a vein in a prone patient.Case Presentation: A healthy volunteer took part in the study. The study protocol includestwo stages: 1) performing a magnetic resonance imaging (MRI) examination to determinethe projection of a certain IVC area on the posterior chest surface (holotopy), 2) performingan ultrasound scanning in the area of IVC projection in order to identify it and determineits dimensions.Conclusion: The 11th intercostal space parallel to the paraspinal line allows to visualizethe IVC in the prone position. This gives a potential opportunity to use it to assess the IVCcollapsibility. Its potential advantage is the ability to assess the compressibility of IVC inthe antero-posterior direction

Objective: One of the most prevalent surgical emergencies is appendicitis, caused by different factors. However, its relation to trauma has not been well-known yet. Here we have described three cases with blunt abdominal trauma and a secondary diagnosis of appendicitis that were transferred to the operation room.Case Presentation: Three patients suffering from blunt trauma and abdominal pain were referred to the emergency department (ED). Of these patients, one of them was transferred to the operation room (OR) with a peritonitis diagnosis and the other two patients had appendicitis signs and symptoms. The abdominal pain and related signs and symptoms of these three patients were due to appendicitis. All three patients were discharged from the hospital with normal vital signs.Conclusion: Traumatic appendicitis might be regarded as one of the differential diagnoses of the patients referred to the ED with blunt abdominal trauma and abdominal pain; hence, appendicitis and blunt abdominal trauma have some unknown relations.

Objective: The aim of this study was to determine the effect of an ultrasound training course on the performance of emergency medical technicians (EMTs) in terms of using extended-focused assessment with sonography in trauma (E-FAST) in the pre-hospital setting.Methods: In this quasi-experimental study, 107 EMTs affiliated to Shahid Beheshti and Kashan Universities of Medical Sciences, were randomly selected. At first, the EMTs were given a pre-test of five images concerning normal and abnormal ultrasound views of thoracic and abdominal cavities. Then, 6 hours of theoretical and practical sessions were done by emergency medicine specialists to teach the EMTs to use ultrasound for the detection of pneumothorax and free fluid. The EMTs were tested again in the form of 18 images post-test as well as a 13-item survey to evaluate their skills in taking correct 10 E-FAST.Results: A total of 107 EMTs with the mean age of 27±15.21 and average of 3.5 years work experience participated in this study. The mean of test score increased from 0.57± 0.19 to 0.81±0.08 (with P < 0.001) out of the total score of 100. In the 4-graded survey, 98% of EMTs obtained good to excellent grades in working with ultrasound machine. Also, 50.5% of EMTs were good in taking Morison’s view and 46.6% and 45.6% had medium grades in pericardial and splenorenal views, respectively. In addition, 22.3% had weak grades in taking pericardial views.Conclusion: The results of the present study showed that the implementation of the training course significantly improved the accuracy of free fluid detection in thoracic and abdominal cavities by EMTs.

Objective: The purpose of the current study was to assess the success rate of posterior tibial nerve block in the ankle with and without ultrasound guidance for pain management in emergency departments. Methods: This clinical trial was conducted on 80 individuals who needed posterior tibial nerve block in the ankle at the emergency department of Hashemi Nejad hospital and Edalatian emergency center in Mashhad, Iran. The eligible individuals were randomly assigned to one of two groups, designated the control (landmark-based nerve block) and the case group (ultrasound-guided nerve block). The two groups were compared in terms of the main measurable outcomes. The data were analyzed using SPSS software (version 20) by nonparametric tests. Results: According to the findings, the mean and median of nerve block success in the landmark-based and ultrasound-guided methods were significantly different between the two groups, both 15 (P=0.02) and 30 (P=0.001) min post-intervention. In this regard, nerve block with ultrasound guidance had a higher success rate compared to the landmark method. However, no significant difference between the two interventions was found in terms of the mean and median of the procedure duration (P=0.8) and injection frequency (P=0.4). On the other hand, the two groups were significantly different regarding the median and mean of patient satisfaction (P=0.00), duration of analgesia (P=0.004), and nerve block-related complications (P=0.03). Conclusion: The findings revealed that the relatively new technique of nerve block by ultrasound-guide resulted in better outcomes than the landmark-based method. Consequently, this method could be adopted to control acute pain in the emergency departments and improve patient care.

Objective: Ultrasonography (US) is not the method of choice for the diagnosis of calcaneal fractures. The aim of this study was to compare the diagnostic accuracy of US with plain radiography in the diagnosis of calcaneus fractures following blunt ankle and foot trauma. Methods: In this cross-sectional study, 214 patients (over 18 years) presenting to the emergency department (ED) with suspicion of traumatic calcaneus fracture following acute blunt trauma, were enrolled. Bedside ultrasonography was performed and interpreted by emergency physicians. After that, plain radiography was performed. Furthermore, all the patients were assessed by computed tomography (CT) scan as the gold standard. Results: Finally, 193 patients were enrolled with a mean age of 29.4±15.7 years (85.5% male). Fractures in the calcaneus were detected in 49 patients. The sensitivity and specificity of ultrasonography in the detection of calcaneal fractures were 83.6%, (confidence interval (CI), 69.7 –92.2) and 100% (95% CI, 96.7 –100), while the sensitivity and specificity of X-ray were 87.7% (95% CI, 74.5 –94.9) and 100% (95% CI, 96.7 –100). There was no false positive result for X-ray and US. Conclusion: Our findings suggest that bedside US with an acceptable sensitivity and specificity can be used as a promising alternative for the diagnosis of calcaneal fracture in ED.

Objective: The current study was performed to provide real-time bedside ultrasonography for emergency medical technicians (EMTs) and assess the advantages and disadvantages of its application in dealing with trauma patients in pre-hospital setting from their viewpoints.Methods: This semi-experimental study was conducted in Tehran, Iran. Twenty EMTs were selected purposefully and underwent a training program. Thereafter, they were asked to perform extended focused assessment with sonography in trauma (eFAST) using a handheld ultrasound device on trauma patients, and also filled a questionnaire prepared (in four components including C1: coherence, C2: cognitive participation, C3: collective action, and C4: reflexive monitoring) based on the normalization process theory (NPT).Results: All 20 participants were men and their average age was 37.8 years (SD = 4.7). For C1, the median total score was 10.5 out of a score of 4-20; For C2, the median score was 6 out of 3-15; For C3, the median total score was 18 out of a score of 6-30; and for C4, the median total score was 11 out of a score of 5-25.Conclusion: Overall, it seems that EMTs welcomed using ultrasonography in dealing with trauma patients in pre-hospital setting. Although they thought that it might somewhat lead to an increase in their workload; but they believed that sufficient training was not provided for them yet. The EMTs were uncertain about the viewpoints of the patients and did not know how it could affect patients’ outcome.

Objective: This study was designed to evaluate the clinical symptoms and sonographic characteristics of femoral trochlear cartilage in patients with knee joint osteoarthritis (OA). Methods: This cross-sectional study was conducted on 94 patients with painful primary knee OA according to the American College of Rheumatology criteria with a visual analog scale pain score of 30 mm or more. Clinical features were evaluated by a rheumatologist according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) criteria, and a radiologist performed ultrasonography within a week. The thickness and echogenicity grade of three cartilage regions were evaluated. Other findings such as meniscal extrusion, effusion, and Baker’s cyst were recorded. Results: The average age of patients was 60 years. The linear regression model showed a significant association of grades II and III trochlear cartilage injury with the pain index, physical activity, and WOMAC overall index. However, there was no significant association between the trochlear cartilage thickness in these three regions and the WOMAC indexes (including pain, physical activity, and the overall index). There was also no significant association between Baker’s cyst and the WOMAC indexes, but a significant association was found between meniscal extrusion and the WOMAC index (P≤0.001). Conclusion: According to our study, the echogenicity grade determined by ultrasonography of femoral trochlear cartilage affects the clinical symptoms of patients including pain. These findings indicate the role of this diagnostic device in understanding changes due to the disease, and it can help physicians focus on the pathology in order to control clinical symptoms in patients.

Objective: Fluid resuscitation is necessary in almost all critical patients. The central venous pressure (CVP) is a well-established method of assessing resuscitation. Recently, there have been attempts to investigate less invasive methods like the diameters of inferior vena cava (IVC) or the jugular vein. We aimed to investigate this method in our research.Methods: Seventy eight critical patients admitted to the emergency department from April 2018 to December 2018 were studied. The CVP was measured along with the diameters of the two mentioned veins before and during resuscitation. The urinary output was also recorded after administering the fluid. The minimum p-value that would illustrate a significant association was equal to 0.05.Results: Findings showed that 53.8% of patients were males and 46.2% were females with an average age of 71.48 years. The causes of the critical state were 25.6% hemorrhagic shocks, 30.8% septic shocks and 43.6% hypovolemic shocks. The mean diameter of the jugular vein before and during resuscitation was 27.21 mm and 25.38 mm, respectively (P = 0.1). The mean of IVC diameter before and during resuscitation was 63.33 mm and 57.98 mm, respectively (P <0.001). The CVP was 4.23 mmHg before resuscitation and 5.61 mmHg after resuscitation (P <0.001). With an average urine output of 201.28 cc, a significant correlation was observed with the increase in the CVP, while no such correlations were observed with the decreasing state of the diameters of the IVC or the jugular vein.Conclusion: Both the IVC diameter and the jugular vein diameter are unable to assess fluid resuscitation independently from respiratory factors

Objective: The aim of this study was to use ultrasonography for the diagnosis and confirmation of Pulled Elbow treatment.Methods: This descriptive cross-sectional study initiated in 2014 and continued until 2015. We used simple sampling method and recruited 60 samples among patients aged 4 months to 6 years. The apparatus used in this study was an ultrasonogram with transducer 12 MHz probe. Ultrasound evaluation of both hands was undertaken and after reduction, the physical examination was performed to confirm the diagnosis made by ultrasonography. Then, the results were recorded by a physician in a checklist and entered into SPSS software (version 20) for further analysis.Results: In this study, 60 children with pulled elbow injuries were studied. Of these, 27 patients (45%) were girls (female) and 33 (55%) were boys (male). This indicates the higher incidence of injury among males than females. The highest incidence of pulled elbow injury was observed in children aged 3 (15%). The accuracy of ultrasonography method for the confirmation of treatment was reported to be 92%.Conclusion: This study aimed to confirm the considered therapeutic method based on the result of ultrasonography performed after the treatment. Accordingly, the sensitivity and specificity of ultrasonography in confirming the considered therapeutic method for the treatment of pulled elbow was obtained higher than 90%.

Objective: This study aimed to determine the association of cardiac risk factors and the risk of Acute Myocardial Infarction (AMI) in Emergency Department (ED) patients with non-diagnostic ECG changes.
Methods: This cross-sectional study was conducted in the ED of Imam Hossein Hospital during a period of one year. In this study, patients with symptoms suggestive of AMI including chest pain, dyspnea, palpitation, syncope, cerebrovascular incidents, nausea, vomitting, dizziness and loss of consciousness were included. The demographic data and risk factors, such as age, gender, history of diabetes, Hypertension (HTN), Hyperlipidemia (HLP), renal failure, positive family history of Coronary Artery Disease (CAD), smoking, substance abuse, alcohol consumption within the past 24 hours and cocaine use within the past 48 hours were recorded. Non-diagnostic ECG included: normal, non-specific, abnormal without ischemic symptoms such as old bundle branch block, Left Ventricular Hypertrophy (LVH), etc. The final diagnosis of AMI was determined by Creatine Phosphokinase-MB (CPK-MB) serum markers and Troponin I. The data were analyzed by using SPSS V. 20 and the level of statistical significance was considered to be P< 0.05.
Results: HTN, HLP, family history of heart disease were significantly higher in those who had non-diagnostic ECG (P< 0.05). However, the ischemic heart diseases were significantly lower in those with non-diagnostic ECG. History of diabetes, stroke, renal failure, alcohol or opium and menopause showed no significant association with non-diagnostic or diagnostic ECG.
Conclusion: Overall, the risk factors are limitedly associated with the occurrence of Myocardial Infarction (MI) in cases where ECG is not diagnostic and it is better to use other criteria to diagnose AMI.
