NCT04153435

Brief Summary

This is an investigator-initiated, multicenter, randomized, placebo-controlled, parallel group, double-blind, superiority trial of calcium during adult out-of-hospital cardiac arrest. 430 adult patients with out-of-hospital cardiac arrest receiving at least one dose of adrenaline will be enrolled. The primary outcome is sustained return of spontaneous circulation and key secondary outcomes include survival at 30 days and survival at 30 days with a favorable neurological outcome.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Sustained Return of Spontaneous Circulation

    Palpable pulses or other signs of circulation without a need for chest compressions lasting at least 20 minutes.

    Before or after hospital arrival (up to 2 hours after the cardiac arrest)

Secondary Outcomes (2)

  • Number of Participants With 30-day Survival

    30 days after the cardiac arrest

  • Number of Participants With 30-day Favorable Neurological Outcome

    30 days after the cardiac arrest

Study Arms (2)

Calcium

EXPERIMENTAL

The intervention will consist of 5 mmol (10 mL ampoule) of calcium chloride (CaCl2) administered intravenously or intraosseously immediately after the first dose of adrenaline and again after the second dose of adrenaline.

Drug: Calcium Chloride

Placebo

PLACEBO COMPARATOR

The placebo will consist of 10 mL of 9 mg/mL sodium chloride (NaCl, "normal saline") administered intravenously or intraosseously immediately after the first dose of adrenaline and again after the second dose of adrenaline.

Drug: Sodium chloride 0.9%

Interventions

Calcium chloride 5 mmol

Data Sharing

IPD Sharing
Will share

Six months after the publication of the last results, all deidentified individual patient data will be made available for data sharing. Procedures, including re-coding of key variables, will be put in place to allow for complete deidentification of the data. Data will be completely anonymized according to Danish law.

Access Criteria
Data will be available for any research purpose to all interested parties who have approval from an independent review committee and who have a methodological sound proposal as determined by the steering committee of the current trial. Only the methodological qualities and not the purpose or objective of the proposal will be considered.
