简要总结
This project is a randomized controlled clinical research design, The hypothesis P-I-C-O of the study is: For adult patients in the Taipei City and New Taipei City communities who have suffered sudden non-traumatic death and have been resuscitated by advanced paramedics, the intervention group that receives combined drug treatment (epinephrine, vasopressin, methylprednisolone) has a better rate of sustained recovery of spontaneous circulation (ROSC) (primary outcome) and long-term survival status (secondary outcomes) compared to the control group that receives single drug treatment (epinephrine).
详细描述
The global and Taiwanese survival rates for patients following an out-of-hospital cardiac arrest (OHCA) are less than 10%. The emergency medical system (EMS) plays a crucial role in patient outcomes after OHCA, providing prehospital cardiopulmonary resuscitation, defibrillation, and medication. Among these medications, the combination of epinephrine, vasopressin, and methylprednisolone holds the most potential to improve patient survival rates following OHCA.
This study aims to compare the effect of standard epinephrine therapy with a combination of epinephrine, vasopressin, and methylprednisolone administered to OHCA patients. This comparison will be made through a randomized clinical trial (RCT) within the EMS of Taipei City and New Taipei City.
Throughout the research plan, we will conduct a prehospital RCT to answer the following question (in P-I-C-O format): Will adult non-traumatic OHCA patients resuscitated by paramedics in a prehospital setting have a better chance of sustained recovery of spontaneous circulation (primary outcome), and improved survival status (secondary outcomes), if they receive combination therapy (i.e., standard doses of epinephrine, 20U of vasopressin after each dose of epinephrine up to a maximum of 80U, and one dose of 40mg methylprednisolone after the first dose of epinephrine) compared to those who receive standard doses of epinephrine? We estimate a sample size of 1,344 OHCA patients to detect a difference in the primary outcome. Based on the background data from the EMS regions under study, we expect the enrollment to take approximately 30 months to complete.
This study is referred to as the "OHCA-REVIVES" trial, which stands for A randomized clinical trial of patient outcomes following Out-of-Hospital Cardiac Arrest Receiving Epinephrine Versus In-together Vasopressin, Epinephrine, and Steroid. The anticipated results from the "OHCA-REVIVES trial" will help determine the optimal strategy for prehospital medication, and will undoubtedly have a significant impact on resuscitation science. Through these efforts, we aim to improve the outcomes of OHCA patients.

研究组 & 干预措施
Intervention group
Combined drug treatment: includes epinephrine (Adrenaline® 1mg/vial) every 3-5 minutes, vasopressin (Pitressin® 20Unints/vial) every 3-5 minutes up to 4 vials (a total of 80Units), methylprednisolone (Solu-Medrol® 40mg/vial).
The method of administration is as follows: after the first administration of epinephrine (Adrenaline® 1mg/vial) to patients with cardiac arrest before hospital arrival, vasopressin (Pitressin® 20Unints/vial) and methylprednisolone (Solu-Medrol® 40mg/vial) are given simultaneously; thereafter, every 3-5 minutes, 1 mg (1 dose) of (Adrenaline® 1mg/vial) is given, along with 20 Units (1 dose) of vasopressin (Pitressin® 20Unints/vial) up to a maximum of 4 doses (a total of 80 Units) of vasopressin can be given before hospital arrival.
干预措施: Combination group (Drug)
Control group
Standard drug treatment: epinephrine (Adrenaline® 1mg/vial). According to international resuscitation guidelines ( Advanced Cardiac Life Support, ACLS), patients with cardiac arrest before hospital arrival are given 1 mg (1 dose) of epinephrine (Adrenaline® 1mg/vial) every 3-5 minutes.
干预措施: Standard group (Drug)
结局指标
主要结局
Rate of sustained return of spontaneous circulation (ROSC)
时间窗: estimated 2 hours
Return of spontaneous circulation (ROSC) is the restart of a sustained heart rhythm measured by pulsation and vital signs that permeate the body after a cardiac arrest. Sustained ROSC ≥ 2 hours has been used as an surrogate to survival to hospital admission in many overcrowded emergency departments (ED).
次要结局
- Rate of prehospital return of spontaneous circulation (ROSC)(estimated 1 hour)
- Rate of survival to hospital discharge(estimated 30 days)
- Rate of survival with favorable neurologic status(estimated 30 days)
