Secondary A,B,C,D

Secondary A,B,C,D 1. Primary confirmation 1. Visualizes ETT goes through the vocal cords 2. Observes vapors in the tube 3. Chest rise 4. 5 point auscultation of the chest

Secondary A,B,C,D

Secondary A,B,C,D

Secondary A,B,C,D – Circulation 1. Establish IV access 2. Identify rhythm  monitor 3. Administer drugs 4. “appropriate for rhythm and condition”

Simultaneous recording of aortic diastolic (red) and right atrial (yellow) pressures during CPR in which 2 ventilations are delivered within 4-second time period Ewy, G. A. Circulation 2005;111:2134-2142

Secondary A,B,C,D

Secondary A,B,C,D – Deferential Diagnosis – search for and treat identified reversible causes

Secondary A,B,C,D 6 H’s 6 T’s – Hypovolemia – Tablets – Hypoxia – Thrombosis “coronary” – Hydrogen Ions “acidemia” – Thrombosis “Pulmonary” – Hyperkalemia / – Tension pneumothorax Hypokalemia – Tamponade, Cardiac – Hypothermia – Trauma – Hypoglycemia

– Checking the heart rhythm – Checking the pulse – inserting airway devices – administration of drugs should be done

Asystole – “Flat line” protocol: 1. Check leads attachment. 2. Check leads selection 3. Power on/off 4. Check the gain

VF pulseless VT

EKG review 1. Tachy vs. Brady 100 < rate < 60 Three questions: 1. Rate 1. Supraventricular vs. 2. QRS narrow or wide ventricular 3. P wave & PR interval 2. Source of rhythm & blocks

Medications 1. Why? (Actions) 2. When? (Indications) 3. How? (Dose) 4. Watch Out! (Precautions)

What is the most important medication in the cardiac arrest?

O2

How to give the medication during CRP? • I.V. • E.T.T – Fast I.V. Bolus. – 2-3 times the I.V. dose – 10 cc N.S. flush. – Raise the arm. – Diluted 10cc N.S. – Use central venous – 3-4 ambo-bag “to access if it available. diffuse the medication”

Which Meds can be given through E.T.T?

Which Meds can be given through E.T.T? NAVEL Naloxon Atropine Vasopressin Epinephrine Lidocaine

Epinephrine • Action : α & β – adrenergic agonist activity • Indication: all Pulseless rhythms. • Dose: • initial dose 1mg ( 10mL of 1:10 000 solution ) • Additional doses of 1mg every 3- 5 min • No maximum dose. • Precautions: • PVC with digitalis. • Hypertension • Myocardial ischemia

Vasopressin • Survival higher in patients who had higher endogenous vasopressin 1,2 • Action : • Vasoconstriction by direct stimulation of the smooth muscle V1 receptor. • Combination with epinephrine resulted in decreased cerebral perfusion 3 • increase coronary perfusion and cerebral oxygen delivery during CPR 4 • Has no β – adrenergic activity. • Indication: all Pulseless rhythms. • Dose: – Start with 40 units I.V. once. – Don’t combine with epinephrine

Vasopressin & Epinephrine no statistically significant differences between vasopressin and epinephrine for death within 24 hrs or death before hospital discharge after a successful CPR. • There is thus insufficient evidence to support or refute the use of vasopressin as an alternative to or in combination with epinephrine in any cardiac arrest rhythm.

Atropine – Action : vagolytic action “SA and AV node” – Indication: asystole & PEA with rhythm < 60/min . – Dose: – initial dose 1 mg – Additional doses every 3-5 min – max dose 3 mg/Kg – Precautions: – Myocardial ischemia

Amiodarone – Action : Na+, K+, Ca++ channel blocker and α & β Blocker. – Indication: shock refractory VF/ Pulseless VT. – Dose: – initial dose 300 mg bolus – Additional doses of 150 mg/kg – Infusion dose of – 1 mg/min for 6 Hr ( 360 mg ) then – 0.5 mg/min for 18 Hr ( 540 mg ) – Maximum dose of 2.2 Gram / 24 Hr – Precautions: – Prolonged QT. – Hypotension – Negative Inotrope

Lidocaine – Action : suppress ventricular arrhythmia, ectopy and prolong the refractory period. – Indication: shock refractory VF/ Pulseless VT. – Dose: – initial dose 1-1.5 mg/Kg – Additional doses of 0.5 – 0.75 mg/kg – max dose 3 mg/Kg – Infusion dose of 1-4 mg/min – Precautions: – Decreased LVH.

Magnesium sulfate • Indication: hypomagnesaemia & Torsades de pointes. • Dose: • initial dose 1-2 gram iv push over 2 min • Infusion dose of 1 gram/hr • Precautions: • Hypotension. • Renal failure.

Sodium bicarbonate • Indications – Pre-existing metabolic acidosis, –↑K – Prolonged arrest > 10 min • Dose: – 1 mEq / Kg • Precautions: – ↑ Na / Hyperosmolality – Metabolic alkalosis – Unfavorable shift of O2-Hb dissociation curve • Contraindication – hypoxic lactic acidosis

Medications Medication 2005 changes Epinephrine •No change Vasopressin •All pulseless rhythms •Can be used in E.T.T Atropine •Maximum dose 3 mg Amiodarone •No changes Lidocaine •No changes
