Regional Anesthesia for Cardiothoracic Enhanced Recovery (RACER)

September 20, 2023 updated by: Chi-Ho Ban Tsui, Stanford University

Regional Anesthesia for Cardiothoracic Enhanced Recovery for Patients Undergoing Cardiac Surgery Via Sternotomy

The erector spinae plane block (ESPB) is a novel regional analgesic technique that provides pain relief with a peripheral nerve block catheter. The goal of this study is to see if bilateral ESPB catheters can improve clinical outcomes in patients undergoing cardiac surgery via sternotomy, such as decreasing the duration of postoperative mechanical ventilation, need for intravenous opioid medications, length of stay in the intensive care unit (ICU), and improving pain scores.

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 (Actual)

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.

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Exclusion Criteria:

  • Participants who cannot give consent
  • Patients who are clinically unstable or require urgent/emergent intervention

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: Bilateral ESP catheter with Lidocaine
All participants will get the Erector Spinae Plane (ESP) catheters. Prior to transfer to the operating room, participants will receive bilateral ESP catheters at T7 level under ultrasound guidance. This arm is the treatment group and will receive lidocaine via alternating side automated infusion pump bolus dosing, continued until chest tube removal or postoperative day 5 (whichever occurs earliest).

This arm is the treatment group and will receive lidocaine via alternating side automated infusion pump bolus dosing, continued until chest tube removal or postoperative day 5 (whichever occurs earliest).
Placebo Comparator: Bilateral ESP catheter with saline
All participants will get the Erector Spinae Plane (ESP) catheters. This arm is the control group and will have normal saline administered via ESP catheters, continued until chest tube removal or postoperative day 5 (whichever occurs earliest).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Opioid Consumption
Time Frame: Duration of postoperative recovery (typically 1-2 weeks)
IV and PO opioid requirements converted to morphine equivalent
Duration of postoperative recovery (typically 1-2 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
