How To Run A code in a Hospital

By: Maged Taman


1- See if patient unresponsive.
2- Activate code, in hospitals call operator for code blue.
3- Usually this is the first step for the code runner to start to run the code. Scan the place in few seconds to get idea what you are for, as identify patient, how he looks, team around you to help it should only take few seconds.
4- Confirm no pulse and no breathing or either.
5- Ensure quick start of the chest compressions if not started yet (about 100/minute and at least 2 inches deep).
6- Confirm the delivery of Oxygen by Ambu bag and monitor O2 saturation.
7- Confirm AED in place and pads on the right position of patient chest wall.
8- Confirm Code status full code or DNR, note the time spent in this may take 1-2 minutes which in this situation may mean survival, many of hospitals have the DNR bracelets in patients wrist.
8- Confirm there is an IV line in place, consider add another line in the future if needed.
9- After 2 minutes from chest compressions, stop chest compressions check the AED monitor for the rhythm, let AED take over it will tell you if it is a shockable rhythm and it will tell you to shock or it will deliver a shock. It will also tell you if it is not a shockable rhythm. Be sure every one stay away from patient including stop ambu bag as the AED tell you do (all Clear) before shock delivery.
10- If the rhythm is shockable (Ventricular tachycardia/fibrillation, V tach/fib) give one shock and resume chest compressions immediately for about 2 minutes before check rhythm again (can resume the sequence for about 2 times more). If patient has normal rhythm or a rhythm that can give him a pulse check for pulse, if there is a pulse check for blood pressure. If no pulse and patient in v tach or v fib consider epinephrine 1 mg amp IV, repeat chest compressions again and the 2 minutes stop for rhythm analysis. Epinephrine can be repeated every 3-5 minutes. One dose of vasopressin 40 units IV can be also considered. Other choices for V tach/fib is Amiodarone one dose push of 300 mg can be followed by one dose of 150 mg push in 3-5 minutes. Amiodarone is also another choice 1-1.5 mg/Kg IV psuh followed by 0.5-1.75 mg/Kg IV push.
10- If the rhythm is nonshockable (asystole or pulseless electrical activity PEA) give epinephrine 1 mg IV every 3-5 minutes. Continue chest compression for 2 minutes and then rhythm analysis as above. Atropine was used in this category but stopped in the new 2010 recommendations.
11- Understand that patient can take any direction can start in asytole and go in V tach/fibrillation or the opposite. Thus both protocols can be used in the same patient. Many times it is the choice between shock or adrenaline.
12- Endotracheal intubation can be considered, however it comes next in after chest compression, ambu bag and shock if indicated in the first few minutes. Should particularly considered if aspiration, hempotysis, angioedema or lodged foreign body in the airway after good suction. Do not confuse that with respiratory arrest which commonly happen before cardiac arrest in Adults and patient in respiratory distress or hypoventilation. Those people in large part may be maintain early a reasonable blood pressure and have a pulse. Intubation is done after sedation is ensured. With no adequate sedation injury to airway could happen and intubation can be difficult. Delay in intubation can result in secondary cardiac arrest.



Thus the most important in CPR is early and semi-vigorous chest compressions as above with ambu bag and AED with delivering shock early after about 2 minutes of chest compressions when indicated. Everything else comes distantly next. Epinephrine is the drug to remember most since it is the only drug for Asystole/PEA and the most effective in V tach/fib. Remember the cycle of 2 minutes chest compression followed by rhythm analysis. Think about shock or IV medications after the rhythm analysis. In most hospitals AED will tell you if need to shock.

Note above is cardiac arrest code which is part of the ACLS or advanced life support which include other acute cadiovascular emergencies.
