  153. 153. You are dispatched to the scene of a pedestrian struck by a vehicle. Law enforcement and the fire department are en route. It is an overcast spring day with a temperature of 50° F (10° C). Scenario
  154. 154. What are your initial concerns as you arrive on the scene?
  155. 155. Ensure the safety of the prehospital care providers and the patient. What are the safety concerns with this scene? Overview
  156. 156. Assess the scene situation to determine the need for additional resources. What additional resources may be needed? Overview
  157. 157. Recognize the kinematics that produced the injuries. What are the factors relating to kinematics implied here? Overview
  158. 158. Use the primary survey approach to identify life-threatening conditions. What are the key concepts of the primary survey? Overview Breathing Airway Kinematics Circulation Disability Expose/ Environment
  159. 159. Provide appropriate management while maintaining cervical spine stabilization. The patient has noisy ventilations and blood is draining from the oropharynx. What should be considered when managing this airway? Overview
  160. 160. The patient’s ventilatory rate is 6 and is shallow. Cyanosis is visible on the patient’s face and fingers. There is bruising across the chest and decreased breath sounds are heard on the left. GCS score is 7 (E-2, V-1, M-4). Support ventilation and deliver oxygen to maintain SpO 2 at 95% or more. How can this be accomplished? Overview
  161. 161. Control any significant external hemorrhage. Overview
  162. 162. Direct pressure controls the external hemorrhage from the right arm. The radial pulse is weak and rapid at about 140 beats/min. The patient is pale, cold, and clammy. There is crepitus and tenderness on palpation of the pelvis and a left thigh deformity consistent with a left midshaft femur fracture. How would you manage these findings? Overview
  163. 163. Provide basic shock therapy, including restoring and maintaining normal body temperature and appropriately splinting musculoskeletal injuries. Consider the use of the PASG for patients with decompensated shock (SBP less than 90 mm Hg) and suspected pelvic, intraperitoneal, or retroperitoneal hemorrhage; and in patients with profound hypotension (SBP less than 60 mm Hg). Overview
  164. 164. Maintain manual spinal stabilization until the patient is immobilized onto a long backboard . When is spinal immobilization indicated? Overview
  165. 165. For critically injured patients, initiate transport to the closest appropriate facility within 10 minutes of arrival on scene. Platinum 10 minutes Golden Period Overview 10
  166. 166. Initiate warmed intravenous fluid replacement en route to the receiving facility. What are the considerations with prehospital fluid therapy? Overview
  167. 167. Ascertain the patient’s medical history and perform a secondary survey when life-threatening problems have been satisfactorily managed or have been ruled out. Overview
  168. 168. Above all, do no further harm.
