Cardio/ cerebral Flashcards
As you walk into the resuscitation bay, what initial steps should be taken to evaluate and manage this cardiac arrest victim?
1- BLS primary survey
2- Obtain finger stick blood sugar
3- ACLS secondary survey
Dentures and airway
- Dentures may be left while bagging–> better seal/ prevent airway occlusion
- should be removed prior to intubation.
Check carotid pulse for ________ time
at least 5 seconds, but not longer than 10 seconds.
Intubation vs circulation
Endotracheal intubation should not delay delivery of defibrillation in patients with a shockable rhythm.
A ________ does not ensure endotracheal intubation.
chest x-ray
endotracheal (ET) tube NAVEL dosing
The optimal dosing has not been established
~2-2 1/2 times the IV route is generally accepted.
NAVEL: ACLS Drugs Safe for Endotrachael Administration
Naloxone Atropine Vasopressin Epinephrine Lidocaine
More than 1/2 of arrests in the US are ________ in origin
cardiac
EKG can offer evidence of cardiac ischemia, various toxin exposure, or hyperkalemia.
Almost all episodes of sudden cardiac death initiate from a ___________
ventricular tachydysrhythmia
Successful resuscitation is dependent on rapid defibrillation.
Improved survival with ventricular tachydysrhythmia is related to ___________ within 10 minutes of onset.
bystander CPR
initial shockable rhythm–> rapid defibrillation
initiation of ACLS
within 10 minutes of onset
Once pulseless VT or VF is identified, the patient should be immediately defibrillated using ___________ (strength of shock)
200J on a biphasic defibrillator
360J on a monophasic defibrillator
ACLS recommends chest compressions should be interrupted only for
ventilation
rhythm checks
shock delivery
After 2 minutes of CPR, _________ should be rechecked
*interruption in CPR less than 10 seconds.
the rhythm should be rechecked
*interruption in CPR less than 10 seconds.
__________ may be given for torsades de pointes.
Magnesium
With PEA, give epin 1mg every 3-5 minutes, but __________ can be substituted for the 1 or 2 dose
Vasopressin 40 U can be substituted for the first or second dose of epinephrine.
___________ should be considered for asystole or slow PEA .
Atropine 1mg IV/IO
may be repeated every 3- 5 min f
max of 3 doses
Studies have shown that resuscitation efforts are unlikely to be successful after ___________ of combined BLS and ACLS
20 minutes
Of pts with return of spontaneous circulation after cardiac arrest, _________ will survive until hospital discharge.
less than one-half will survive until hospital discharge.
ACLS recommends unconscious pts with return of spontaneous circulation should be cooled to ___________ when VF was the initial rhythm.
32-34 C for 12-24 hours
*mild hypothermia has shown ↓ 6 month mortality rate with improved recovery at discharge
Inclusion Criteria for Therapeutic Hypothermia
- Patients resuscitated after out-of-hospital witnessed arrest with VT/VF as initial rhythm
- Resuscitation initiated by EMS within 5-15
- No more than 60 min from collapse to return of spontaneous circulation
- Persistent coma after ROSC
- Adult age
- intubation and mechanical ventilation
Contraindications to Therapeutic Hypothermia
- Severe cardiogenic shock (SBP<90 mmHg) despite fluids and inotropes
- coma not cardiac arrest (overdose, CVA)
- Known coagulopathy
- Life-threatening arrhythmias
- Initial temperature <30 C
- Pediatric/ Pregnancy
costochondritis
inflammatory process of costochondral / sternal joints
–> localized pain and tenderness
Hyperkalemia cardiac Rx
- unstable cardiac rhythm–> Calcium (gluconate/ chloride)
- no ECG abnormalities–> potassium binding resins (Kayexalate)
Absolute contraindications to TPA include
- Previous hemorrhagic stroke
- Known intracranial neoplasm
- Active internal bleeding (excluding menses)
- Suspected aortic dissection or pericarditis
Troponin level vs time
- rise 3-6 hours of CP onset
- peak 12-24 hours,
- remain elevated for 7-10 days
pericarditis classic s/s
-chest pain, a pericardial friction rub, and diffuse
ST-segment elevation
-pain relieved by sitting forward and worsened by lying down or swallowing
