Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Shock Trauma Resuscitation (2 of 5) Body Splinting – Splinting must be effective and performed quickly. – Best accomplished by aligning limbs and securing body on long spine board.

Upper Saddle River, NJ Interaction with Other Care Providers Providing information to other health care providers: – Mechanism of injury – Results of assessment Injuries Normal or abnormal history Vital signs and trends Patient age, sex, and weight AMPLE history – Interventions Information must be clear and concise. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Body Substance Isolation at the Trauma Scene (1 of 2) Handle contaminated materials while wearing PPE. Dispose of contaminated linens, clothing, dressing, and equipment in properly labeled containers. Dispose of sharps in punctureresistant sharps container. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Body Substance Isolation at the Trauma Scene (2 of 2) DO NOT recap sharps. DO NOT stick sharps into mattresses. Scan the scene prior to departure to ensure that contaminated material has been collected. Contact Infection Control Officer if personnel become contaminated. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Air Medical Transport (1 of 7) Indications for air transport – Ground versus air transport If ground transport time exceeds 20 minutes, helicopter transport may be warranted. Air transport equates to 1 min/2 miles. Consider rendezvous with helicopter. – Consider placing helicopter on standby. Limitations for air transport – Weather – Dispatched to another call – Down time for maintenance Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc.

Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Air Medical Transport (4 of 7) Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Air Medical Transport (5 of 7) Flight Physiology – Higher altitude = less pressure on patient Internally trapped air exerts more pressure. Conditions that can worsen: Asthma COPD Tension pneumothorax Interventions that can worsen: PASG can increase in pressure exerted. Cuffed ET tubes expand. Pressure infusing bags exert more pressure. Air splints exert more pressure. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Air Medical Transport (6 of 7) Flight Considerations – Confined working area. – Limited ability to perform procedures. Intubation Chest decompression CPR Application of PASG – Fully immobilize patient prior to transport. – Ensure that any ALS interventions are patent and secured. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Air Medical Transport (7 of 7) Air Medical Patient Preparation – Assure maximal oxygenation. – Assure maximal ventilation. – Administer high-flow oxygen. Consider intubation or RSI. If patient airway status is marginal or deteriorating. – Assess for pneumothorax. Decompress prior to loading. – Establish 2 large-bore Ivs. – Provide flight crew with complete and abbreviated patient report. Bledsoe et al., Paramedic Care Principles & Practice Volume 4: Trauma © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Research and Trauma Research must occur to assure that EMS uses procedures beneficial to patient outcomes. – Outcomes include discharge from hospital. NOT delivering a “live” patient to the hospital. All EMS personnel must participate to ensure optimal patient care.
