Study summary

This is a randomized, double-blind, controlled clinical trial is to evaluate the duration of efficacy of parasternal blocks with the use of local anesthetic adjuncts for analgesia after coronary artery bypass grafting surgery.

Read the detailed description

This study will randomize patients to either standard pain control protocols or parasternal blocks after coronary artery bypass grafting-only surgery. This study will specifically examine the effectiveness and duration of analgesia of parasternal blocks with local anesthetic adjuncts, Dexamethasone 10mg and Dexmedetomidine 50mcg, added to the local anesthetic mixture

What researchers measure

Primary outcomes

  1. Pain with inspirometry at 24 hours after surgery

    Numerical Rating Scale (NRS) pain score from the sternotomy site during inspirometry. The VAS score is a scale from 0 to 10 where 0 is equivalent to "no pain" and 10 is equal to "the worst imaginable pain"

    Time frame: 24 hours after surgery

Secondary outcomes

  1. Opioid consumption

    Amount of opioid administered (mg of Dilaudid)

    Time frame: 12, 24 and 48 hours after surgery

  2. Amount of rescue analgesia administered

    Amount of ketorolac or ketamine administered

    Time frame: Total in the first 48 hours after surgery

  3. Pain score at rest

    Numerical Rating Scale (NRS) pain score from the sternotomy site during inspirometry. The VAS score is a scale from 0 to 10 where 0 is equivalent to "no pain" and 10 is equal to "the worst imaginable pain"

    Time frame: 12, 24 and 48 hours after surgery

  4. Pain score with inspirometry

    Numerical Rating Scale (NRS) pain score from the sternotomy site during inspirometry. The VAS score is a scale from 0 to 10 where 0 is equivalent to "no pain" and 10 is equal to "the worst imaginable pain"

    Time frame: 12 and 48 hours after surgery

  5. Intensive Care Unit (ICU) Length of Stay

    Time spent in the intensive care unit after surgery (days)

    Time frame: From surgery until discharge from the ICU, assessed from the date of surgery up until 6 months after the completion of the study

  6. Hospital Length of Stay

    Time spent in the hospital after surgery (days)

    Time frame: From the date of surgery up until discharge from hospital, followed from the date of surgery up until 6 months after the completion of the study

  7. Inspirometry

    Volume inspired on inspirometry

    Time frame: 24 hours after surgery

  8. Patient satisfaction with pain control

    0 "extremely unsatisfied" to 10 "extremely satisfied"

    Time frame: at 48 hours after surgery

  9. Mobilization

    Time from ICU arrival to the first mobilization to a chair

    Time frame: From ICU arrival until first mobilization (approximately first 48 hours postoperatively)

  10. Ambulation

    Time from ICU arrival to the first mobilization to a chair

    Time frame: From ICU arrival until first ambulation (approximately first 72 hours postoperatively)

Other outcomes

  1. Presence of postoperative vomiting

    Vomiting after surgery

    Time frame: first 48 hours after surgery

  2. Incidence of bradycardia

    Heart rate less than 60 beats per minute

    Time frame: first 48 hours after surgery

  3. Incidence of hyperglycemia

    Glucose greater than 10 millimoles/liter

    Time frame: first 48 hours after surgery

  4. Incidence of a pneumothorax

    Pneumothorax identified on chest x-ray

    Time frame: first 48 hours after surgery

  5. Local anesthetic toxicity

    Local anesthetic toxicity, as diagnosed clinically

    Time frame: first 48 hours after surgery

  6. Postoperative Delirium

    Delirium as defined by the "Confusion assessment method for the ICU" (CAM-ICU)

    Time frame: first 48 hours after surgery

  7. Narcotic prescription on discharge

    Having a narcotic prescription on discharge

    Time frame: Upon discharge from hospital after surgery (approximately 1 week after surgery)

  8. Sternal pain at 3 months

    Persistent pain at the sternum

    Time frame: Three months after the day of surgery

  9. Local anesthetic spread

    Number of levels of spread of local anesthetic, as identified by ultrasound

    Time frame: Immediately as intervention is performed

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2022 to primary completion in Apr 2023, 15 months.

Of 39 non-industry phase 3 interventional studies under Pain, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 51. This study's 15 months is below that.

Counting every sponsor, half of 57 studies reached it within 23 months; a quarter within 11 and three quarters within 50.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 10, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
