Brief summary
The purpose of this study is to determine whether there is potential benefits of prophylactic antibiotic treatment in comatose survivors of out-of-hospital cardiac arrest (OHCA) treated in intensive care unit with therapeutic hypothermia.
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.
Interventions
Patients without evidence of tracheobronchial aspiration were randomized to immediate prophylactic Amoxicillin-Clavulanic acid 1,2 gr/8h

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Value of C-reactive protein (CRP) at day three | Three days after admission to Intensive care unit (ICU) | Expressed in milligram/litre (normal \<5 mg/L) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Severity of systemic inflammatory response estimated by peak value of procalcitonin (PCT) | 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 | Expressed in microgram/litre (normal \<0.5 microgram/L) |
| Severity of systemic inflammatory response estimated by peak value of neutrophil Cluster of differentiation 64 (CD 64) | First measurement at admission in hospital and afterwards in 24 hours intervals in the first three days | Neutrophil CD 64 expression was used as an index of sepsis with \>1.2 indicating greater likelihood of sepsis |
| Appearance of pneumonia on chest X ray | 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 | Mini-BAL was performed on the third day after the sudden cardiac arrest | — |
| Severity of systemic inflammatory response estimated by peak white blood cell count (WBC) | 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 | Expressed in number of white blood cells x 109 per litre (L) |
| Duration of tracheal intubation | From the day of admission until the extubation. This was always during the ICU stay- one month | 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 |
| Duration of mechanical ventilation | From the admission until spontaneous breathing . This was during ICU stay-one month | Duration of mechanical ventilation was expressed as days the patient needed the mechanical support for breathing regardless of mode of support |
| ICU stay | From the admission until the patient was transferred to ward, usually less than one month | — |
| Survival with good neurological outcome | Up to six months after the event | Good neurological outcome was characterised using cerebral performance category (CPC) with 1-2 indicating good neurological recovery. |
| Incidence of positive hemocultures | From the admission until the patient was transferred to the ward. This was always during the ICU stay-one month | — |
