120J/150J/200J/200J
stable:
(1) MAGNESIUM SULFATE: 50mg/kg over 5-10 minutes, max 2g
Seizure algorithm
- ongoing when we arrive or lasting >5 minutes; or more than 2 in one hour
- pregnancy / postpartum: manage with mag
- check blood sugar
- manage airway (suction / ventilate as needed)
- administer benzos:
VERSED 0.2mg/kg IM/IN (max 5mg if <40kg; max 10mg if >40kg)
ATIVAN or VERSED 0.1mg/kg IV/IO (slow push; max single dose 4mg) - monitor ETCO2
no ketamine for postictal patients
Syncope / Presyncope algorithm
- includes both LOC and presyncope or “nearly blacking out”
- check blood sugar
- 12 lead
- 500 mL fluid bolus if symptoms of poor perfusion; repeat as necessary
Sepsis algorithm
- check blood sugar
- ETCO2 and SPO2
- 12 lead
- 30 ml/kg fluid bolus
- treat per “shock” algorithm as indicated
Indicators for sepsis
- SUSPECTED INFECTION OR IMMUNOSUPPRESSION(open wounds / UTI / pneumonia / meningitis / indwelling medical device / vomiting or diarrhea / recent surgery or procedure / chronic steroid use)
=> high risk: chemotherapy / sickle cell / bone marrow or organ transplant / severe intellectual disability
AND
- 2 OR MORE MARKERS OF SYSTEMIC INFLAMMATORY RESPONSE SYNDROME –Temp > 100 or < 97
- HR > 90
- RR > 20
- glucose > 140 in non-diabetic
- altered
(3. findings of shock)
Hypoglycemia algorithm
- less than 60 mg/dL
- ORAL GLUCOSE 15g PO; may repeat x1 as needed
- DEXTROSE (D10) IV; 1ml/kg max 250mL (25g); titrate to effect
or
-GLUCAGON 1mg IM/IN (may repeat) - reassess blood sugar
** patients with insulin pump: if altered: stop insulin pump or disconnect at insertion site; if GCS 15 leave connected with pump running
Hyperkalemia algorithm (a reversible cause of cardiac arrest)
If findings are present:
- Peaked T waves progressing to sine waves
-wide QRS
- Pt: renal failure / Addison’s / crush syndrome / rhabdo

Blood thinners?
TBI?
- FLUID THERAPY: If SBP <90 or HR >120; give 1L bolus
- manage pain
- consider TXA if hemorrhagic shock potential (and w/n 3 hours of injury): 1 g
- absent/diminished lung sounds in hypotensive pt: tension pneumo? … needle decompress
- avoid hypothermia
Crashing Medical Patient algorithm
(new onset altered LOC, airway issues, signs of shock …)
- do not initiate movement of patient until tx is optimized
- need trending vital signs
- initiate cardiac monitoring and ETCO2
- BLS AIRWAY: NPA/OPA; NRB; BVM
- ALS AIRWAY: NRB or CPAP; i-gel or intubate
- CIRCULATION: unstable brady –> (see algorithm); unstable tach –> (see algorithm); cardiogenic: 30 ml/Kg fluid bolus
- SHOCK unresponsive to fluids: push dose EPI
TBI algorithm
(Consider mechanism, GCS, exam)
avoid the H bombs
- high flow O2: target 100% // aggressively prevent desat below 90%
- BVM at 10 breaths/min
- trend vital signs/GCS/ and monitor for shock (tachy, falling SBP
- blood sugar / C-Spine / control bleeding with direct pressure if no open skull injury
- IV/IO
avoid hypotension for SBP approaching 100mmHG: aggressive fluids (1 L bolus) - monitor for hypoventilation/apnea (target ETCO2 40mmHg)
- consider advanced airway if O2<90%

- **HYPERventilation
- **HYPOtension
- **HYPOxia
