Blood Gas Analysis and Buffering In Cardiac Arrest (BABICA)

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Prause Gerhard, MD, Medical University of Graz
ClinicalTrials.gov Identifier:
NCT01362556
First received: April 27, 2011
Last updated: June 2, 2014
Last verified: June 2014
  Purpose
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.

Condition Intervention
Cardiac Arrest Drug: Sodium bicarbonate Drug: Sodium Chloride

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Blood Gas Analysis and Buffering In Cardiac Arrest - A Multicenter, Prospective, Randomised, Double Blind Prehospital Trial to Evaluate the Impact of Early Blood-gas-analysis Targeted Buffer Therapy on ROSC After OOHCA

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
