About this study

Official title: Prophylactic Versus Clinically-driven Antibiotics in Comatose Survivors of Out-of-hospital Cardiac Arrest

Read the detailed description

Postresuscitation management of comatose survivors of out-of-hospital cardiac arrest (OHCA) significantly improved and "bundle of care" including therapeutic hypothermia, immediate coronary angiography, percutaneous coronary intervention (PCI) and contemporary intensive care nowadays leads to survival with good neurological recovery. Benefit of prophylactic antibiotics, which may suppress development of postresuscitation infection and especially early onset pneumonia and thereby decrease the severity of postresuscitation systemic inflammatory response, is controversial. Because of these uncertainties, the investigators performed a single-center randomized clinical trial comparing prophylactic versus clinically-driven administration of antibiotics in comatose survivors of OHCA. The investigators hypothesized that prophylactic antibiotics may decrease the severity of postresuscitation systemic inflammatory response by reducing the incidence of postresuscitation infection and especially pneumonia which was further addressed by repeat microbiological sampling.

Conditions: Out-of-hospital Cardiac Arrest
Being tested: Amoxicillin-Clavulanic acid
Keywords: Out-of-hospital cardiac arrest, Prophylactic antibiotics
Medical subject headings: Out-of-Hospital Cardiac Arrest

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Amoxicillin-Clavulanic acidDrug
Also called Amoksiklav, Augmentin
Patients without evidence of tracheobronchial aspiration were randomized to immediate prophylactic Amoxicillin-Clavulanic acid 1,2 gr/8h

Study groups in NCT02899507
Study group	Role	What they receive
Prophylactic antibiotic	Experimental	Amoxicillin-Clavulanic acid 1.2g every 8h Receives: Drug: Amoxicillin-Clavulanic acid
Clinically-driven antibiotics	No intervention	Administration of antibiotics in clinically-driven group was at the discretion of attending intensivist. Selection of antibiotic in clinically-driven group was empirical or based on the results of bacterial cultures if already available.

What is being measured

The primary outcome is the main question the study is designed to answer.

Value of C-reactive protein (CRP) at day three
Expressed in milligram/litre (normal <5 mg/L)
Measured: Three days after admission to Intensive care unit (ICU)

Secondary outcomes (10)

Severity of systemic inflammatory response estimated by peak white blood cell count (WBC)
Expressed in number of white blood cells x 109 per litre (L)
Measured: First measurement at admission in hospital and afterwards in 24 hours intervals during stay in the intensive care unite (ICU) but not longer then first seven days
Severity of systemic inflammatory response estimated by peak value of procalcitonin (PCT)
Expressed in microgram/litre (normal <0.5 microgram/L)
Measured: First measurement at admission in hospital and afterwards in 24 hours intervals during stay in the intensive care unite (ICU) but not longer then first seven days
Severity of systemic inflammatory response estimated by peak value of neutrophil Cluster of differentiation 64 (CD 64)
Neutrophil CD 64 expression was used as an index of sepsis with >1.2 indicating greater likelihood of sepsis
Measured: First measurement at admission in hospital and afterwards in 24 hours intervals in the first three days
Appearance of pneumonia on chest X ray
Measured: Chest X ray was taken on admission and afterwards on daily basis during the stay in the intensive care unite but not longer than first week
Incidence of positive blind mini bronchoalveolar lavage (Mini-BAL) on day 3
Measured: Mini-BAL was performed on the third day after the sudden cardiac arrest
Incidence of positive hemocultures
Measured: From the admission until the patient was transferred to the ward. This was always during the ICU stay-one month
Duration of tracheal intubation
Duration of intubation was expressed as days of intubation started with admission until the extubation. Because this is being done in intensive care unite, the time frame is duration of ICU stay
Measured: From the day of admission until the extubation. This was always during the ICU stay- one month
Duration of mechanical ventilation
Duration of mechanical ventilation was expressed as days the patient needed the mechanical support for breathing regardless of mode of support
Measured: From the admission until spontaneous breathing . This was during ICU stay-one month
ICU stay
Measured: From the admission until the patient was transferred to ward, usually less than one month
Survival with good neurological outcome
Good neurological outcome was characterised using cerebral performance category (CPC) with 1-2 indicating good neurological recovery.
Measured: Up to six months after the event

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Amoxicillin-Clavulanic acid in people with Out-of-hospital Cardiac Arrest, run by University Medical Centre Ljubljana at 1 site in Slovenia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Value of C-reactive protein (CRP) at day three (time frame: Three days after admission to Intensive care unit (ICU)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02899507, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2016.
