Brief Summary

  1. 1.Background:
  2. 2.Materials and methods:
  3. 3.Sample Size Calculation Set the following assumptions: alpha 0.025, beta 80%, clinically significant difference of 5% and 25% ROSC rate for both arms. Assuming the sample has an equal number of subjects in each arm, the study need to include at least 1178 subjects per arm to reach statistical significance.

Outcome Measures

Primary Outcomes (1)

  • return of spontaneous circulation (ROSC)

    ROSC can be identified with the following three conditions: 1. arterial pulse can be reached; 2. effective ECG rhythm; 3. systolic blood pressure \> 60 mmHg (1 mm Hg = 0.133 kPa);.

    within 24 hours

Secondary Outcomes (5)

  • first attempt success

    within 24 hours

  • overall success

    within 24 hours

  • initial access interval

    within 24 hours

  • initial epinephrine administration interval

    within 24 hours

  • sustained ROSC

    24 hours

Other Outcomes (5)

  • survival to discharge

    a week

  • survival to discharge without severe neurological impairment

    a week

  • 1-month survival without severe neurological impairment

    1 month

  • +2 more other outcomes

Study Arms (2)

Group IO

EXPERIMENTAL

Intraosseous assess will be established in group IO, using EZ-IO for drug or fuild resuscitation. Proximal tibia is the insertion site,locating at 1 cm medial tibial tuberosity. IO access should be retained for less than 1 day, and venous access should be established as soon as possible after winning rescue time to continue treatment. Other treatment measures refer to 2015 AHA guidelines.

Device: EZ-IO

Group IV

NO INTERVENTION

Intravenous access will be established in group IV, choosing any available peripheral venous for the administration of drugs or fluids.The antecubital vein is the preferred choice. If failed, the next catheterization plan will be determined by the physician in charge of the scene.Other treatment measures also refer to 2015 AHA guidelines.

Interventions

EZ-IODEVICE

The insertion site locates at 1 cm medial tibial tuberosity. EZ-IO (U.S. Teleflex® Corporation) will be used with an adult 15G needle. Pull out the needle when having a sense of frustration, withdraw the bone marrow with the syringe, bolus 20 mL of normal saline to open intramedullary path and begin drug resuscitation at the same time. The retention time of IO route should be less than 24 h, and venous access should be established after winning rescue time as soon as possible to continue treatment.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Out of hospital cardiac arrest patients with 18 years or more

You may not qualify if:

  • Traumatic cardiopulmonary arrest with an indication of withholding of resuscitation, including:
  • trauma victims with injuries that are obviously incompatible with life, such as decapitation or hemicorporectomy;
  • victims of either blunt or penetrating trauma when there is evidence of prolonged cardiac arrest, including rigor mortis or dependent lividity;
  • blunt trauma patient who, on the arrival of emergency medical services (EMS) personnel, is found to be apneic, pulseless, and without organized electrocardiographic activity;
  • penetrating trauma patients who, on the arrival of EMS personnel, is found to be pulseless and apneic and there are no other signs of life, including spontaneous movement, electrocardiographic activity, and pupillary response;
  • Vascular access has been established before admission;
  • Return of spontaneous circulation before first attempt to establish vascular access;
  • Quit resuscitation;
  • Patients with contraindications of intraosseous access;
  • infection of insertion site, such as skin and soft tissue infections, osteomyelitis;
  • integrity damage of the target bone, such as fractures, artificial limbs, etc;
  • blood supply or return of the target bone is significantly affected, e.g. arteriovenous rupture;
  • burns of insertion site;
  • intraosseous attempt in same insertion site within 24 h;
  • compartment syndrome exists in same insertion site;
  • +3 more criteria

Data Sharing

IPD Sharing
Will not share

Though data that will be collected in our study are huge and multicentral, it is limited in part provinces of China, which makes it hard to apply for other centers in the world , so we do not have a plan to share IPD with other researchers.
