The debate over the administration of sodium bicarbonate in cardiac arrest has been going on for several decades, swinging like a pendulum from "first-line drug" to "not indicated" to the recent guidelines advocating "a small bolus under special conditions (metabolic acidosis, intoxication, long-term resuscitation)". A targeted, blood-gas controlled application under optimised ventilation conditions has not yet been evaluated prehospitally. Our preliminary studies have shown that an arterial puncture/line as well as measurement of blood gases is feasible in preclinical conditions. This multicentre trial including 5 centres and 10 physician-staffed emergency systems is designed to compare, in a prospective randomised controlled study, the effect of a calculated dosage of sodium bicarbonate based on the patient´s base deficit and weight, on ROSC (= return of spontaneous circulation) and on the secondary survival of cardiac arrest patients. The null hypothesis is that there is no or negative impact on survival.

Primary Outcome Measures:
  • Rate of return of spontaneous circulation (ROSC) [ Time Frame: Within five hours from start of resuscitation. ]

Secondary Outcome Measures:
  • Survival to discharge after cardiac arrest [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 weeks ]
    Discharge from hospital

  • Survival after one year of hospital discharge [ Time Frame: One year after event ]

Estimated Enrollment: 700
Study Start Date: March 2011
Study Completion Date: June 2014
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Sodium Chloride
Group receiving sodium chloride 0.9% after arterial blood gas analysis in cardiac arrest.
Drug: Sodium Chloride

Administration of a calculated amount of sodium chloride 0.9% [SC] after arterial blood gas measurement according to Base Excess [BE] and Body weight [kg].

Formula: SC [ml] = -BE * kg * 0.1

Active Comparator: Sodium Bicarbonate
Group receiving targeted sodium bicarbonate 8% therapy after arterial blood gas analysis in cardiac arrest.
Drug: Sodium bicarbonate

Administration of a calculated amount of sodium bicarbonate 8% [SB] after arterial blood gas measurement according to Base Excess [BE] and Body weight [kg].

Formula: SB [ml] = -BE * kg * 0.1
