Sustained Inflation and Chest Compression vs 3:1 C:V Ratio in Asphyxiated Newborns (SUR1VE-2)

April 28, 2026 updated by: University of Alberta

Sustained Inflation and Chest Compression Versus 3:1 Chest Compression to Ventilation Ratio During Cardiopulmonary Resuscitation of Asphyxiated Newborns - a Multi-centre, International Cluster Randomized Control Trial

Newborn infants who require cardiopulmonary resuscitation at birth receive chest compression using a 3-Compression to 1-Ventilation (3:1 C:V) ratio. However, the optimal chest compression technique during cardiopulmonary resuscitation is uncertain and identified as a critical gap in evidence.

The International Consensus Statement advises to use the 3:1 C:V ratio based on animal studies, and states that there are no clinical trials to support this approach and called for more research. There continues to be uncertainty about the optimal chest compression technique during cardiopulmonary resuscitation.

This trial will compare if in newborn infants with cardiac arrest in the delivery room does providing CC+SI (a new chest compression technique) compared to 3:1 C:V decreases the incidence of all mortality within the initial hospital stay.

This will be a multi-centre international cluster randomized trial.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
554

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Newborns with gestational age born between 28 to 43 weeks based on best available obstetrical estimate
  • Newborns designated to receive full resuscitation, i.e., parental request or pre-determined decision to provide only comfort care at birth
  • No known major congenital or chromosomal malformation. All newborns who meet inclusion criteria will be enrolled as the centres agreed to change their local hospital policy during the trial. The inclusion criteria are designed to be pragmatic and provide useful knowledge translation for most of the patient population in the future.

Exclusion Criteria:

- Newborns born outside of study centers and transported to centers after delivery.

Sex, race, and ethnicity are not part of the exclusion criteria for this trial, and as such it should represent the combined demographics of all centers involved.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: CC+SI (Chest compression during sustained inflation)
CC+SI Group (Intervention group): Newborns randomized to "CC+SI" will receive CPR with a SI using a peak inflation pressure (PIP) of 30cmH2O while receiving CC. The PIP was chosen based on our animal studies and two previous clinical trials. CC will be performed at a rate of minimum 90/min. Each SI will be delivered for duration of 30sec with a 1 sec pause between the next SI for 30sec is started while CCs are continued. After 2x30sec CC+SI (total of 60sec), Heart rate (HR) will be assessed: A HR <60/min means CC+SI is continued for another 60sec (2x30sec CC+SI), followed by another HR assessment. If HR >60/min, CC are stopped (current standard of care). CC+SI will continued until ROSC.
Procedure: CC+SI (Chest compression during sustained inflation)
CC+SI (Chest compression during sustained inflation)
Active Comparator: 3:1 C:V (3:1 Compression:Ventilation ratio)
3:1 C:V Group (Control group - Standard of Care): Newborns randomized to "3:1 C:V" will receive a CC rate of 90/min and 30 ventilations/min as per current resuscitation guidelines. The PIP used for the 30 inflations will also be 30cmH2O) as per current resuscitation guidelines. Every 60sec, a HR assessment as per neonatal guidelines will be performed to assess if HR is <60/min - continue CC or >60/min - stop CC (current standard of care). 3:1 C:V will be continued until ROSC.
Procedure: 3:1 C:V (3:1 Compression:Ventilation ratio)
3:1 C:V Group (Control group - Standard of Care): Newborns randomized to "3:1 C:V" will receive a CC rate of 90/min and 30 ventilations/min as per current resuscitation guidelines. The PIP used for the 30 inflations will also be 30cmH2O) as per current resuscitation guidelines. Every 60sec, a HR assessment as per neonatal guidelines will be performed to assess if HR is <60/min - continue CC or >60/min - stop CC (current standard of care). 3:1 C:V will be continued until ROSC.
