EMS REGION VIII SOPs 2014 UPDATES July 2014 2014 Updates Effective August 1, 2014 SOP books will be distributed by each System SOP Changes SOP Page Number References Anywhere an SOP is referenced, the SOP is noted in BOLD type and the page number is also included Easier to locate SOPs that refer to another other SOPs Terminology: Standard Precautions “Standard precautions” has replaced the old wording “body substance isolation” (BSI) and “universal blood and body secretions” Fentanyl Dosing for Adults Fentanyl dosing is changed and is now consistent for adults (< 65 YO) regardless of SOP 2012 SOPs did not allow for a repeat dose of fentanyl for the adult suspected cardiac patient with chest pain 2014 SOPs allow for a repeat dose of fentanyl Must have a systolic BP > 100 mmHg Fentanyl Dosing for Adults The initial fentanyl dose remains the same for all adult patients < 65 year olds 1mcg/kg SLOW IV/IM, max 100 mcg Addition of one repeat dose 0.5 mcg/kg SLOW IV/IM after 5 min, max 50 mcg Fentanyl Dosing > 65 Years Old New dosing for patients > 65 years old Slower renal clearance of drugs More likely to experience adverse effects of opiates (even at lower doses) Initial and repeat dosages are the same, regardless of SOP Must have a systolic BP > 100 mmHg 0.5 mcg/kg SLOW IV/IM, max dose 50 mcg Repeat dose 0.25 mcg/kg SLOW IV/IM, max dose 25 mcg Adverse Effects of Fentanyl AMS, respiratory depression (particularly if >65 YO) Stupor Delirium Somnolence Dysphoria Chest wall-rigidity Muscle rigidity (involving the respiratory musculature including the glottis) Seizures Difficulty or inability to ventilate the patient Adverse Effects of Fentanyl Hypotension Bradycardia Nausea/vomiting Constipation Arrhythmias (rarely) Hypersensitivity side effects including anaphylaxis have been reported on rare instances Pediatric Fentanyl Dosing Dosing for pediatrics has NOT changed 1 mcg/kg SLOW IV/IM, max dose 100 mcg Remember: most pediatric dosages don’t exceed the adult dose! Obtain accurate weight from parents/caregivers No repeat dose, but can call Medical Control to request additional dosing as appropriate NO IO route for fentanyl administration in peds If the patient requires an IO, stabilizing the patient takes priority to giving pain medication. Fentanyl Administration Administering fentanyl too quickly can cause chest wall rigidity IV administration should be over 1-2 minutes If using a saline lock, push the fentanyl over 1-2 minutes, then push the saline flush over 1- 2 minutes as well Fluid Bolus In all SOPs, the phrase “Fluid Challenge” has been replaced with “Fluid Bolus” Administering a large amount of IV fluid in a relatively short period of time is a fluid bolus. Remember to reassess your patient after administration of each bolus Vital signs, including pulse characteristics Lung sounds (crackles) Change in condition Pleural Decompression “Pleural decompression” has replaced “needle decompression” throughout the SOPs General Patient Assessment Page 2 Initial Assessment, Breathing Addition of “assess lung sounds” A reminder that auscultation of lung sounds should occur in the primary assessment stage of patient care Zofran (ondansetron) Page 4 Adult Initial Medical Care Zofran (ondansetron) may now be administered 4 mg tab ODT or 4 mg slow IV x1 dose. Patients must be actively vomiting and/or nauseous prior to administration Onset of action of IV Zofran (ondansetron) is twice as fast as ODT Administer over 1-2 minutes IV (no less than 30 seconds) Zofran (ondansetron) Not approved for prophylactic administration (prevention) of nausea or vomiting Can only be given IV or ODT once – NOT both.

Oxygen Delivery Devices Non-rebreather Mask – delivers 10-15L, approximately 90% concentration, of O2 Indications for use: respiratory distress, trauma Contraindications: CO2 retainer such as COPD exacerbation Bag-valve Mask – delivers15L, 90%+ concentration, of O2 Indications for use: respiratory failure, support for bradypnea or apnea, positive pressure to open the airway/alveoli (this is used to administer oxygen and ventilations BOTH) Ventilation vs Oxygenation *** REMEMBER: the provider is the best “monitor” *** If available, combining pulse-ox and capnography are ideal for monitoring oxygenation and ventilation, as providers can detect insufficiencies early and intervene While they are helpful tools, Pulse-oximeters and capnometers do not treat the patient, YOU DO The provider in charge of the airway and ventilating needs be able to focus on this task only so as not to have poor outcome that hyperventilating a patient can cause BREAK TIME Scenario 1 EMD / BLS EMD/BLS • Call comes in as an 8 year old shortness of breath from the local elementary school • EMD: What questions would you ask the caller? • EMD: Which units would you dispatch?

Cardiac Rhythm of the Month Torsades de Pointes An uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the isoelectric line Associated with prolonged QT intervals, which can be congenital or acquired (such as drug therapy induced or other body system disorders) Tends to occur in bursts that are not sustained but can recur and may degenerate into ventricular fibrillation (VF) Torsades de Pointes Patient presentation may include: Palpitations Dizziness Syncope Nausea Cold sweats Shortness of breath Chest pain Sudden Cardiac Death Treatment: Determine if patient has a pulse and then follow the appropriate ventricular tachycardia SOP Magnesium is ultimate drug of choice Lowers the amplitude of early afterdepolarization (EAD) by decreasing the influx of calcium Scenario 3 ALS ALS Scenario Your medic unit is dispatched for the 44 year old female shortness of breath Upon arrival, you find the patient in a tripod position, having difficulty getting more than a word or 2 out Appearance: awake, alert, anxious Work of Breathing: increased effort Circulation: pale, diaphoretic ALS A – patent B –intercostal and substernal retractions, diffuse wheezes C –strong peripheral pulses, cap refill 2 seconds Vitals: B/P:168/94 P: 130 R: 40 T: 100.4 S – cough, dyspnea A – environmental, no drug allergies M –Xopenex, Xyzal, Chantix P – asthma with intubation in the past, allergies, smoker L – dinner last night E – URI symptoms x2 days, labored breathing is new onset today and she tried 2 nebs prior to your arrival ALS Asthma Exacerbation Possible Status Asthmaticus Need to correct the hypoxemia caused by narrowing and blocked airways Follow ADULT ACUTE ASTHMA SOP Slap the Cap (monitor waveform capnography for trends with treatments – note the “shark fin” appearance in bronchospasm Airways affected by asthma ALS Consider CPAP early to: Decrease Recruit Splint work of breathing, reducing fatigue alveoli and improved oxygenation larger airways, reducing airway collapse and mucous plugging Als skill review Continuous Positive Airway Pressure (CPAP) CPAP Prehospital indications for CPAP use: Congestive Heart Failure Asthma/COPD Drowning Carbon Monoxide Poisoning Pulmonary Infections CPAP Contraindications: Cardiogenic Shock Patient is hypotensive and CPAP increases intrathoracic pressures, thereby lowering venous blood return to the right side of the heart Altered Mental Status or unconscious Facial Trauma, anomalies or stroke with facial droop Pneumothorax or penetrating chest trauma Persistent nausea/vomiting Agonal respirations/respiratory arrest CPAP Additional Education from Bob Spoula – Edward Hospital Respiratory Therapy Educator (CPAP PowerPoint) Questions?
