At the end of this simulation learners will be able to: 1) Perform team-focused CPR using effective leadership and communication skills during prehospital resuscitation. 2) Employ high-quality CPR with an emphasis on compressions and early defibrillation. 3) Demonstrate appropriate airway management utilizing an oropharyngeal airway and bag-valve-mask, blind-insertion airway device, and/or endotracheal intubation during cardiac arrest. 4) Recognize and appropriately defibrillate pulseless ventricular tachycardia and ventricular fibrillation. 5) Formulate an appropriate differential diagnosis for pulseless electrical activity.

Talonavicular Dislocation

The X-rays were significant for a subtalar dislocation. The calcaneus (red) is laterally displaced with respect to the talar head (orange), and the white lines indicate the normal articular surface. Additionally, there was a talonavicular dislocation, as seen in the fourth image: the talus (green) and navicular bone (purple) overlapping suggests a dislocation. In a normally aligned foot, the boundaries of the two bones create a point of articulation.

Endocarditis

Upright frontal radiograph of the chest demonstrated large pleural effusion on the left and moderate pleural effusion on the right as shown by the visible menisci on both sides (red arrows) with diffuse bilateral nodular densities (yellow dotted lines), consistent with septic pulmonary emboli. Computed tomography (CT) of the chest demonstrated multiple scattered lung nodules bilaterally containing internal foci of air cavitation (green dotted lines).

Facial Fracture Induced Periorbital Emphysema

Hamid Ehsani-Nia, DO^* and Robert Eisenstein, MD^*

DOI: https://doi.org/10.21980/J8F05HIssue 3:4[mrp_rating_result]

Physical exam showed marked left palpebral subcutaneous crepitus, as well as bulbar and palpebral conjunctival bulging. Visual acuity was normal with intact extraocular movements, and normal pupillary exam. Computed tomography (CT) imaging of the face was obtained and revealed multiple displaced fractures involving the left orbital floor and zygomatic arch associated with moderate periorbital and postseptal extraconal gas, resulting in orbital proptosis.

Fournier Gangrene

Joseph Zakaria, BS^*, Steve Bunch, MD^* and Victor Cisneros, MD, MPH^*

DOI: https://doi.org/10.21980/J89626Issue 3:4[mrp_rating_result]

The computed tomography (CT) of the abdomen and pelvis revealed significant subcutaneous gas tracking along the perineum and right gluteal region (orange outline) into the scrotum with associated scrotal edema (yellow arrow) and subcutaneous inflammatory fat stranding of 0.92 cm (red arrow) consistent with Fournier’s gangrene. There is early fluid loculation along the right medial gluteal cleft of 5.85 cm (green arrow) without a sizeable drainable abscess seen.

Foreign Body in Maxillary Sinus: A Rare Case of Chronic Rhinosinusitis

Richard Barnett, DO^* and Meigra Chin, MD^*

DOI: https://doi.org/10.21980/J85H09Issue 3:4[mrp_rating_result]

Computed tomography (CT) sinus with contrast demonstrated complete opacification of left paranasal sinuses and nasal cavity, and a linear radiopacity within the left maxillary sinus consistent with a foreign body. There were additional left facial subcutaneous radiopaque opacities.

Brief Review of Intussusception Diagnosis and Management

The patient’s abdominal ultrasound revealed intussusception in the right upper abdominal quadrant. The transverse ultrasound view showed a “doughnut sign” (dashed yellow line), telescoping bowel (yellow arrow), and invaginated hyperechoic mesenteric fat with crescent configuration (dashed orange line). The sagittal ultrasound view demonstrated the intussusception formed by the outer recipient bowel loop (yellow arrows), invaginated hyperechoic mesenteric fat (orange asterisks), and telescoping bowel centrally (red arrow).
