EMS: Prolonged Care and Care in Place Timothy R. Hurtado, DO Front Range Emergency Specialists Penrose-St. Francis Hospitals
Disclosure • Nothing to disclose
Objectives • Discuss issues for prolonged field care to include • Trauma • Cardiac • Pediatrics
Overall goals • Unique aspects • “stay and play” • “load and go”
Case 1 • 58 y/o male • Rollover MVC • Restrained • 60 MPH, moderate damage to interior • c/o CP, leg pain, pain in his pelvis
Exam • ABCs • Secondary • Appears to be in pain • Obvious open femur fracture • Crepitus and pain with palpation of pelvis • 178/110, 100, 22, 95% RA
History • NKDA • Medications: prn ibuprofen • Past Medical History: “I never go to the doctor, I don’t have any problems” • Last meal: 10 minutes ago, “I was eating a supersize meal while driving” • Events prior: “I became nauseous, got horrible heartburn then passed out I think”
Case 1 • What else do you want to know?
Case 1 • Assessment? • Open femur fracture • Possible pelvic fracture • STEMI • MVC • Plan? • IVx2, O2, monitor, Fluids?, ASA?, Nitroglycerin?, pain meds?
Subacute trauma management • Management of: • Hypotension • Pain • Fluids • Environment
Fluid management • What is the optimum fluid? • Isotonic fluids • Colloids • Hypertonic fluids • Blood substitute (oxygen carrying substitutes)
Fluid management • What is the optimum amount? • When should it be given?
Bleeding control • Direct pressure • Proximal pressure points? • Topical hemostatic agents • Tourniquets
Tourniquets • Apply 2 inches proximal to bleeding site • Tighten until bleeding stops • Provide pain medication • Recheck
Pelvic pain and crepitus • Stabilization required • Sheet adequate • Commercially available devices
Pain control • Options? • Route? • Amounts? • Side effects?
Environment • Environmental control paramount • Lethal triad in trauma • Acidosis • Hypothermia • Coagulopathy • So keep your patient warm!
Case 1 • Pitfalls of the acute management of a STEMI • Hypotension • Arrythmias • Mechanical complications • Cardiogenic shock • Vfib/Vtach arrest/sudden cardiac death • Pericarditis
Arrhythmias • Generalized autonomic dysfunction that results in enhanced automaticity of the myocardium and conduction system • Increased concentrations of circulating catecholamines, and local release of catecholamines • 90% of patients will develop a arrythmia • Greastest risk in first hour after event
Arrhythmias • Sinus tachycardia • Afib/Aflutter • Bradycardia • AV blocks • Bundle branch blocks • Ventricular arrhythmias
Arrhythmias • Sinus tachycardia
Arrhythmias • Atrial flutter
Arrhythmias • Atrial fibrillation
Arrhythmias • Bradycardia
Arrhythmias • AV blocks 1st degree 2nd degree Mobitz 2nd degree type II
Arrhythmias • Premature Ventricular Contractions
Arrhythmias • Nonsustained ventricular tachycardia
Arrhythmias • Sustained ventricular tachycardia
Arrhythmias • Ventricular fibrillation
Cardiogenic shock • clinical definition is decreased cardiac output and evidence of tissue hypoxia in the presence of adequate intravascular volume. • diagnosis at bedside by observing hypotension, absence of hypovomeia, and clinical signs of poor tissue perfusion, which include oliguria, cyanosis, cool extremities, and altered mentation. • Treatment- O2, vasopressors (dopamine), (+/-) diuretics if volume overloaded
Mechanical complications • Ventricular free wall rupture • Ventricalseptal rupture • Acute mitral regurgitation
Pericarditis • Acute pericarditis • 10%, and this complication usually develops within 24-96 hours • clinical presentation may include severe chest pain, usually pleuritic, and pericardial friction rub. • aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs).
Summary • Prolonged transport times • Keep patient warm • Crystalloids are still fluids of choice • Avoid over resuscitation with fluids in patients with uncontrolled hemorrhage • Many options for adequate pain control • Be aware of multiple complications in cardiac patients
Patient 2 • 4 y/o female • CC: abdominal pain and chest pain • History: Restrained passenger involved in MVC • PMHx: Asthma • 112/84, 138, 28, 92% RA
Exam • ABCs • Interactive, appropriate for situation • Multiple ecchymotic regions to the right chest wall, flank and abdomen
Case 2 • Assessment? • Blunt chest and abdominal trauma • Plan? • IV, O2, monitor, pulse ox • Fluids? • Pain medications?
So what’s different about kids? • Vital signs • Hypotension is a late sign of shock • SBP= 70+ (2 x age in years) • Children have a larger body surface area • Larger calvarium compared to adults percentage wise • Consider early IO access • Consider a fluid bolus of 20 ml/kg
Chest trauma • Children have relatively compliant chest walls • May be no external signs of trauma • Higher incidence of pulmonary contusions • Usually delayed in onset
Abdominal Trauma • Abdominal palpation most helpful part of exam • Ask child where they hurt • Two most common injuries are blunt hepatic and splenic lacerations
Sudden deterioration? • Airway • Position? • Tidal volume? • Rate? • Pneumothorax? • ET tube • Dislodged? • Plugged? • Right main? • IV/IO access • Infiltrated? • Dislodged? • Medications? • Unrecognized bleeding • Chest? • Pelvis? • Abdomen? • Ext? • Retroperitoneum? • Unrecognized injuries
Summary • Consider potential complications of patients when there are long transport times • Control environment to the greatest extent possible • Be prepared for the decompensating patient and have a plan
