For the self-study to the seminar by the students of the 5th year of study specialty: general medicine and dentistry) on the discipline «Emergency and urgent medical care»
THEME 2. THE PROCEDURE FOR PROVIDING EMERGENCY MEDICAL CARE TO VICTIMS AND PATIENTS AT THE PRE-HOSPITAL STAGE. SECONDARY EXAMINATION..
Vinnytsa - 2020 Trimodal distribution of death 1. INTRODUCTION TO TRAUMA
CNS/cardiovascular
hypoxia/hypercarbia MOF/sepsis
Trimodal Pattern of mortality following severe trauma GOLDEN HOUR
⚫ The first hour following a trauma during which aggressive resuscitation can improve the chances of survival and restore the normal functions.
⚫ Early pre-hospital care, early transport, aggressive resuscitation and interventions in ED, continued care in ICU have a definite and significant role in preventing deaths due to trauma. PLATINUM MINUTES
⚫ THE IMPORTANCE OF TIME IN TRAUMA IS INCREASING AS EVIDENT FROM THE EVOLUTION OF THE CONCEPT OF
“THE PLATINUM TEN MINUTES” INITIAL APPROACH TO TRAUMA CARE ⚫ Process that consists of -Initial primary assessment -Rapid resuscitation -A more thorough secondary assessment -Followed by diagnostic tests and disposition. TRAUMA TEAM

CHEST
➢ Inspect
➢ Palpate
➢ Percuss
➢ Auscultate
➢ Obtain x-rays Classic Radiographic Findings ◼ Diaphragmatic rupture w/ spleen herniation
28 Secondary survey
ABDOMEN
➢ Inspect
➢ Auscultate
➢ Palpate
➢ Percuss
➢ Reevaluate
➢ Special studies Abdominal Trauma ⚫ Look for distension, tenderness, seatbelt marks, penetrating trauma, retroperitoneal ecchymosis ⚫ Be suspicious of free fluid without evidence of solid organ injury FAST Exam
⚫ Focused Abdominal Scanning in Trauma ⚫ To find free fluid (blood) around heart (pericardiac eff.) or abdominal organ (hemoperitoneum) after trauma ⚫ 4 views: – Cardiac – RUQ (Morison’s Pouch) – LUQ (Perispleenic Space) – Pelvic (Pouch of Doughlas) Splenic Injury
⚫Most commonly injured organ in blunt trauma ⚫Often associated with other injuries ⚫Left lower rib pain may be indicative ⚫Often can be managed non- operatively Liver injury
⚫ Second most common solid organ injury ⚫ Can be difficult to manage surgically ⚫ Often associated with other abdominal injuries Hollow Viscous Injury
⚫ Injury can involve stomach, bowel, or mesentery ⚫ Symptoms are a result from a combination of blood loss and peritoneal contamination ⚫ Small bowel and colon injuries result most often from penetrating trauma ⚫ Deceleration injuries can result in bucket- handle tears of mesentery ⚫ Free fluid without solid organ injury is a hollow viscus injury until proven otherwise Secondary survey
⚫ Perineum:contusion,hematoma, laceration,urethral blood
⚫ Rectum:sphincter tone,high riding prostate,pelvic fracture,rectal wall integrity,blood
⚫ Vagina:blood,laceration Secondary survey
Musculoskeletal ⚫ Contusion, deformity ⚫ Pain ⚫ Perfusion ⚫ Peripheral neurovascular status ⚫ X-ray Secondary Survey
Musculoskeletal: Pitfalls
➢ Potential blood loss
➢ Missed fractures
➢ Soft-tissue or ligamentous injury
➢ Compartment syndrome (especially with altered sensorium / hypotension) Adjuncts to Secondary Survey
◼ Radiology – Standard emergent films ◼ C-spine, CXR, Pelvis – Focused Abdominal Sonography in Trauma (FAST) – Additional films ◼ Cat scan imaging ◼ Angiography ◼ Foley Catheter – Blood at urethral meatus = No Foley catheter ◼ Pain Control ◼ Tetanus Status ◼ Antibiotics for open fractures
38 Minimize missed injuries?
➢ High index of suspicion
➢ Frequent reevaluation and monitoring REEVALUATION
⚫ New findings / deterioration / improvement
⚫ High index of suspicion ==> early diagnosis & management
⚫ Continuous monitoring
⚫ Pain relief Records, Legal Considerations
➢ Concise, chronologic documentation
➢ Consent for treatment
