If tachycardia is stable what are some non medication therapies you can try?

Vagal stimulation: Carotid massage Bearing down Ice (for kids)

What is a common reason for Vfib/Vtach in kids?

Underlying heart defect Electrocution

What is the pediatric dose for epi?

0.01 mg/kg repeat every 3-5min Max dose 1mg

What is the pedi dose for atropine?

0.02 mg/kg max single does 0.5mg

What is the pedi dose for amiodarone?

5 mg/kg

What is the pedi dose for lidocaine?

1 mg/kg

What is the defib joule amount for kids?

2 J/kg intially Subsequent 4 J/kg

At what HR do you start doing chest compressions in kids?

Less than 60bpm

What is the initial treatment for pediatric bradycardia?

Epi

If a pedi patient has stable bradycardia what med can be given?

Atropine--faster onset than glyco

Why do you want to have atropine close by when giving succinylcholine to a pediatric patient?

2nd dose can commonly cause bradycardia in kids

What is considered tachycardia for kids 1-8 y/o?

180 bpm

What is considered tachycardia for infants?

220 bpm

What is the biggest cause of tachycardia in pedi popualation?

Fever Hypovolemia Treat underlying issue (not usually cardiac problem)

If a pedi patient has unstable tachycardia how many Joules should you cardiovert with?

0.5 J/kg then move up to 2J/kg

When should a neonate start being ventilated?

HR less than 100 probably not adequately oxygenation--start ventilating

What is common with BMV in neonates?

Abd distension--would be good idea to have gastric compression with NGT

Potential etiology for maternal cardiac arrest:

Anesthetic complications Bleeding Cardiovascular Drugs Embolic Fever General nonobstetric causes of cardiac arrest (H/Ts) Hypertension

What is targeted preductal SpO2 after birth?

1 min: 60-65% 2 min: 65-70% 3 min: 70-75% 4 min: 75-80% 5 min: 80-85% 10 min: 85-95%

What is the max shock energy for defib in pediatric population?

10 J/kg or adult dose

What is the endotracheal dose of epi in peds if no IV/IO access?

0.1mg/kg

Pedi CPR with ETT vs without:

Change compressor every 2 minutes, or sooner if fatigued * If no advanced airway, 15:2 compression-ventilation ratio * If advanced airway, provide continuous compressions and give a breath every 2-3 seconds

How many times can pediatric amiodarone be repeated for refractory VF/pulseless VT?

5mg/kg repeated up to 3 total doses

What happens during the initial stabilization phase for adult post cardiac arrest?

Manage respiratory parameters Start 10 breaths/min Spo2 92%-98% Paco2 35-45 mm Hg SBP >90 DBP > 65 administer crystalloids and/or vasopressor obtain 12 lead

Steps in adult post cardiac arrest care if patient if comatose:

* TTM: 32-36 degrees for 24 hours * Obtain brain CT * EEG monitoring (continuous or intermittent) * Other critical care management

What treatment may be indicated for cardiopulm compromised wide QRS (>0.09 sec) with pulse in kids?

Synchronized cardioversion

How to respond to kid with HR 200 bpm narrow QRS, absent p waves, RR interval fixed with normal mental status and BP:

SVT Consider vagal maneuvers Give adenosine

9 year old patient is alert/oriented with stable BP. HR is 190bpm QRS is 0.1sec. Whats the next move?

Possible V tach regular rhythm QRS monomorphic consider adenosine

What is the probable rhythm in kids when rate is elevated, P waves are present, and RR interval is variable?

Sinus tachycardia

Treatment for adult normal QRS tachycardia w/ pulse and without hypotension/AMS/cardio issues:

Vagal maneuvers Adenosine (if regular) Beta blocker/ CCB Expert consult

How does treatment differ for adult wide complex (>0.12sec) tachycardia with pulse/hypotension/AMS vs same rhythm that is asymptomatic?

Synchronized Cardioversion for unstable persistent tachycardia Adenosine/anti-arrhythmic infusion for wide complex "stable" tachycardia (procainamide, amio, sotolol)

1mg every 3-5 minutes max 3mg

What do you do if adult pt has unstable (hypotensive, AMS, shock) persistent bradycardia?

pace Atropine

What can you try if atropine doesnt work and adult pt still has unstable bradycarda?

Transcutaneous Pace and or Dopamine or Epi infusion
