About this study
Official title: Liposomal Bupivacaine Vs Bupivacaine with Dexmedetomidine in an Erector Spinae Plane Block for Mastectomies in Cancer Patients: a Randomized Control Trial
Perform a comparison of effective pain relief duration between liposomal bupivacaine and dexmedetomidine when added to bupivacaine in a block for mastectomy for cancer surgery. The erector spinae plane block is a well-established block that is utilized for post operative pain control for procedures performed on the soft tissue of the chest and chest wall as well as intrathoracic procedures. The goal is comparison of the effective duration of both study groups to determine if there is a significant difference in time and amount of post operative opioids required which admitted to hospital.
Read the detailed description
Performance of a single-blinded randomized control trial to evaluate effectiveness of postoperative pain control in erector spinae plane blocks with bupivacaine with liposomal bupivacaine as the control versus bupivacaine with dexmedetomidine. Plan to randomize patients by alternating months, so that odd months' patients will receive bupivacaine 0.25% with liposomal bupivacaine in the erector spinae plane block. Even months patients will receive bupivacaine 0.25% with dexmedetomidine in the erector spinae plane block.
Block will be performed with ultrasound by the Acute Pain Service team. A time out confirming location of surgery, allergies, consents completed prior to start of the block. Patients will be monitored with 5 lead electrocardiography, non-invasive blood pressure, and pulse oximetry. After skin wheal with 1% lidocaine via 25-27 g needle and echogenic 20 g needle will be utilized to perform the block. The needle will be placed under direct ultrasound visualization into the erector spinae plane. The plane will be hydro dissected with normal saline to confirm needle tip has accessed the erector spinae plane. The local anesthetic will be given in a total of 0.2 ml/kg up to 20 mls (selected based on the study group placement) and aspiration will occur every 5 mls during the block. This will be repeated on the second side if a bilateral block is indicated in based on the surgical consent. All patients will receive 10 mg IV dexamethasone post-induction of anesthesia.
While the patient is in patient pain scores and milligrams of morphine equivalence (MMEs) will be collected every 6 hours based on charting by the nurses providing care starting from time "0" in the PACU after surgery, up until discharge. Then to obtain pain scores up to 72 hours after surgery, patients will be called at home after 72 hours and asked what their pain scores had been daily since discharge and a total of tabs taken daily.

|---|---|---|
| Liposomal bupivacaine and bupivacaine plain erector spinae plane block | Active comparator | Erector spinae plane block performed on the surgical side (left, right or bilateral) as appropriate based on planned surgical consent. Utilizing ultrasound to see the fascial layers and guide the needle placement under direct visualization. Block will include 1.33% liposomal bupivacaine 10ml plus 0.25% bupivacaine plain 20 ml per side of the block. Receives: Drug: Liposomal bupivacaine |
| Bupivacaine plain with dexmedetomidine | Experimental | Erector spinae plane block performed on the surgical side (left, right or bilateral) as appropriate based on planned surgical consent. Utilizing ultrasound to see the fascial layers and guide the needle placement under direct visualization. Block will include 0.25% bupivacaine plain 30 ml plus dexmedetomidine 0.5 mcg/kg per side of the block. Receives: Drug: Dexmedetomidine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Is bupivacaine with dexmedetomidine superior to liposomal bupivacaine in both density and duration?
Control group erector spinae plane block with liposomal bupivacaine is less dense and not as long lasting as bupivacaine with dexmedetomidine experimental group. Will investigate initial visual analog scale (VAS) pain scores to determine how effective the block is after surgery and every 6 hours while in patient. Additionally, calling the patient discharging after 96 hours from the time of the block and collect daily pain scores from the patient. This is to establish which group had best pain scores throughout and longest duration of lowest pain scores.
Measured: 96 hours
Secondary outcomes (1)
Evaluate oral milligram of morphine equivalent (MME).
Same control and experimental group assessing for morphine milligram equivalents reduction between groups. Will investigate milligram of morphine equivalent every 6 hours to see how much each group requires. In particular looking for increasing trend in morphine equivalence over time. Additionally, calling the patient discharging after 96 hours from the time of the block and collect daily opioid medications taken by the patient and converting to milligram morphine equivalents. This is to establish which group has taken the least amount of morphine equivalents throughout the duration of the block, as an indication to the duration of optimum benefit of the block.
Measured: 96 hours

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Dexmedetomidine and Liposomal bupivacaine in people with Breast Cancer, run by United States Naval Medical Center, Portsmouth at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 19 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
