Introduction

You are doing your morning rounds when you hear 'Code Blue, Medicine 1' over the loudspeaker. As a resident in the hospital, you know you will likely be playing a team leader role, at least initially, with this code.

 

You quickly make your way to the room. There are three nurses already there, and chest compressions are underway.

 

One of the nurses gives you a quick history: Mr Wilmont is 68 years old. He was admitted two days ago with acute myocardial infarction. He was found pulseless, though his vitals were stable and he was fine 30 minutes ago.

 

What are your first steps?

CPR is underway.

Administer oxygen if available.

Attach a monitor and check the rhythm.

Secure IV/IO access.

Work to secure airway.

 

The rhythm shows ventricular fibrillation.

 

How do you proceed?

Give one shock:     manual biphasic: device specific: 120-200 J,        AED: device specific         monophasic: 360J

Resume CPR, give 5 cycles, and check rhythm.

When avaialble, given vasopressor:

  • epinephrine 1mg IV/IO q 3-5 min or
  • vasopressin 40 U IV/IO x1

Continue with 5 cycles and do a rhythm check.

The rhythm continues to show ventricular fibrillation.

What do you consider next?

During the second, or subsequent rounds of CPR, consider:

  • amiodarone 300 mg IV/IO once, and then 150 mg IV/IO once, or
  • lidocaine 1-1.5 mg/kg, the 0.5-0.75 mg/kg, to a maximum of 3 doses or 3 mg/kg

Consider magnesium 1-2g IV/IO for torsades de pointes

 

You do a rhythm check after the next five cycles.

Rhythm shows asystole.

 

Ho do you treat this?

Continue giving epinephrine 1mg IV/IO every 3-5 min.

Consider atropine 1mg IV/IO for asystole every 3-5 min, to a maximum of 3 doses.

 

What tratable causes should you consider?

Consider the H's and T's:

  • hypovolemia
  • hypoxia
  • hydrogen (acidosis)
  • hypo/hyperkalemia
  • hypoglycemia
  • hypothermia
  • toxins
  • tamponade
  • tension pneumothorax
  • thrombosis: coronary or pulmonary
  • trauma

 

Morning bloodwork, drawn 1 hour before the arrest, reveals a normal set of electrolytes.

Mr Wilmont does not respond to three doses each of epinephrine or atropine, and after 20 minutes, you decide further treatment is futile. You end the code.

 

A post-mortem analysis reveals a large thrombus occluding the left mainstem artery, the likely cause of his death.
