Brief Summary

The Carilion Clinic and Virginia Tech Carilion School of Medicine, in conjunction with Roanoke Fire-EMS, Botetourt County Department of Fire \& EMS and Salem Fire-EMS, are studying the outcomes of patients experiencing Pulseless Electrical Activity (PEA). PEA refers to a type of cardiac arrest in which there is normal electrical activity in the heart however the heart still fails to contract to generate a pulse. Without heart contractions, which normally generates a pulse, the brain and other important organs fail to receive blood and oxygen. Unfortunately, the majority (97.3%) of patients that experience this rhythm do not survive and most don't even make it to the hospital. This study is trying to determine if the administration of a High Calcium, Low Sodium (HCLS) fluid in pre-hospital care will improve the chances of survival. Generally, a sodium (salt) solution is provided to patients experiencing cardiac arrest. Studies have shown that lower sodium and higher calcium content may activate certain parts of the heart cells required to generate a pulse under PEA conditions. This study is a double-blind, prospective, clinical trial. PEA patients will randomly receive either routine fluid therapy (salt solution) or a HCLS solution. While HCLS solution is not the standard fluid used by EMS providers responding to PEA, it is composed of FDA approved components and is occasionally used by EMS providers at their discretion in treating PEA. It is predicted that HCLS will either improve PEA survival or deliver similar outcomes as routine treatment. All patients will receive standard, high quality cardiac arrest and post-cardiac arrest care regardless of assigned treatment group.

Study Arms (2)

High-Calcium, High- Sodium (HCHS) group

ACTIVE COMPARATOR

Patients will receive a drip of blinded, intravenous, normal saline and an unblinded, intravenous, one gram bolus of calcium chloride.

Drug: High Calcium, High Sodium (HCHS) Crystalloid Therapy

High-Calcium, Low- Sodium (HCLS) group

EXPERIMENTAL

Patients will receive a drip of blinded, intravenous, half-normal saline and an unblinded, intravenous, one gram bolus of calcium chloride.

Drug: High Calcium, Low Sodium (HCLS) Crystalloid Therapy

Interventions

Half-normal saline IV drip and 1g IV bolus Calcium Chloride.

Also known as: (NDC) National Drug Code NDC 0264-7800-00 and NDC 0409-4928-11
High-Calcium, Low- Sodium (HCLS) group

Normal saline IV drip and 1g IV bolus Calcium Chloride.

High-Calcium, High- Sodium (HCHS) group

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • All patients who present with PEA at any time during the patients' treatment by Roanoke Fire-EMS, Botetourt County Department of Fire \& EMS and/or Salem Fire-EMS. This study defines a PEA presentation as any patient who is unconscious, presenting without a carotid pulse and with non-(VT/VF) ventricular tachycardia/ventricular fibrillation electrical activity.

You may not qualify if:

  • Patient less than 18 years old
  • Known pregnancy
  • Duration of untreated cardiac arrest of more than 30 minutes
  • Traumatic cardiac arrest
  • Known (LVAD) Left Ventricular Assist Device
  • Rapidly fatal underlying disease
  • Known or suspected digitalis toxicity
  • A physical, durable (DNR) Do Not Resuscitate (or durable DNR medical jewelry) presented to EMS before treatment with asserting a preference not to be enrolled
  • Prisoners and other populations with involuntary consent

Masking Details
Patients, being intrinsically unconscious from PEA, will be blinded to the intervention. EMS Supervisors, in the pre-hospital setting, will administer an opaque bag of fluids with only a bag number on it, ensuring that they are blinded to the intervention. Hospital providers/outcomes assessors will know that patients were enrolled in a study and they will only know which bag number was used. The investigator will have the capacity to unblind bag numbers, but the investigator will not be the provider or outcomes assessor for patients due to the emergent nature of PEA.
