cardiac arrest, post cardiac arrest syndrome, TNF-α antagonism
Brief summary
The investigators assessed the effect of TNF-α antagonism within 6 hours of return of spontaneous circulation on 30-day mortality in patients who remained comatose after cardiopulmonary resuscitation (CPR) following cardiac arrest . In addition, the investigators explored the role of this treatment in modulating the systemic inflammatory response and its potential impact on 90- and 180-day morbidity and mortality and neurological outcomes.
Interventions
The TNF-α antagonist (infliximab) used by the experimenter was manufactured by Hisun Biopharmaceuticals Ltd. under the trade name anbaite.The dosage was administered at 5 mg/kg, dissolved in 250 mL of 0.9% sodium chloride injection, and delivered via intravenous infusion over 2 hours.
Patients in the control group received 250 mL of 0.9% sodium chloride injection as a placebo, administered via intravenous infusion over 2 hours.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 30-day survival rate | 30 days after randomization. | All-cause survival rate of patients on day 30 after randomization. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of good neurological function assessed by Modified Rankin scale neurologic function scores and cerebral performance category scores | 30 days, 3 months, and 6 months after randomization | Modified Rankin scale neurologic function scores and cerebral performance category(CPC) scores at 30 days, 3 months, and 6 months after randomization. Neurological function was assessed using the CPC and mRS scales, with CPC 1-2 and mRS 0-3 scores indicating a good neurological prognosis, and CPC 3-5 and mRS 4-6 scores indicating a poor neurological prognosis. |
| prolong follow-up survival rate | 3 months and 6 months after randomization | survival rate |
| systematic scoring | 24 hours (h), 48 hours, 72 hours and 1 week after randomization | SOFA score at 24h, 48h, 72h and 1 week after randomization |
