Detailed Description
Study Design:
This is a prospective, single-institution, parallel-group, single-blinded, randomized-controlled, two-arm, effectiveness study comparing bupivacaine liposomal injectable suspension (Exparel®) versus regular bupivacaine hydrochloride (HCl).
Procedure:
In patients aged 18 and over who require sternotomy, thoracotomy, mini-thoracotomy, or laparotomy incisions will be screened and consented for potential enrollment. Patients will be randomized following consenting to either Exparel® or regular bupivacaine hydrochloride group.
Course of Study:
The study will accrue patients over the course of 4 years.
Enrollment:
Enrollment will consist of all adult patients aged 18 and over undergoing surgical procedures requiring sternotomy, thoracotomy, mini-thoracotomy, or laparotomy incisions. Patients will be screened and consented preoperatively. If the patient is deemed eligible and consents to participate, randomization will occur and the patient will be considered enrolled.
Recruitment:
The target for enrollment will be 280 patients (the study target sample size per power analysis, but actual enrollment will be greater (330 patients) to account for exclusions for various reasons in order to achieve the target recruitment).
Risks:
There is a small increased risk to the patients by participating in the study in addition to a possible chance of breach in patient confidentiality as the study involves evaluation of an FDA-approved drug. As detailed in the informed consent, the subjects are at risk of developing adverse effects from Exparel®, described on the drug packet insert and from HCl Bupivacaine, also described on the drug packet insert. The investigators do not expect any additional physical risks other than an unintentional disclosure of sensitive patient health information.
Data Safety Monitoring:
As the Principal Investigator of this study, Dr. Charlton-Ouw from the Department of Cardiothoracic and Vascular Surgery at The University of Texas at Houston Medical School will conduct the data safety monitoring of this study. He will annually meet with all other co-investigators to review the patients enrolled in this study. As part of the data safety monitoring plan, all patients enrolled until that point in time would be unblinded in order to review the outcomes. Additionally, in view of the uncertainty attached to the treatment effects in this heterogeneous population, owing to limited currently available data, an independent Data Safety Monitoring Committee, will oversee the progress of the trial.
IND#:
The drugs that will be used are already approved by the FDA and do not have IND/IDE#
Proposed Funding Source:
The study is internally funded and is investigator-initiated.
Communication of Study Results:
The communication of study results will occur only between authorized individuals who are listed to take part in the study through our department. The individuals who will take part in the study will acknowledge and adhere to the importance of patient safety and the protection of their private information. The results of this study will be analyzed and published after the approval of the principal investigator, co-investigators, and biostatistician in a peer-reviewed scientific journal and/or presented at an international/national scientific conference or meeting regardless of outcome.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Exparel®
Patients in this group will receive will receive the study drug [bupivacaine liposomal injectable suspension (Exparel®)] and Patient Controlled Analgesia (PCA).
Exparel® is an FDA-approved bupivacaine liposome injectable suspension produced by Pacira Pharmaceuticals.
|
Participants will receive 266mg of liposomal bupivicaine (equivalent of one 1.3% 20ml vial of EXPAREL®) diluted in 60ml of preservative-free normal (0.9%) sterile saline for a total volume of 80mL.
Drug will be administered at the end of the procedure just prior to wound closure.
Other Names:
Patients will have access to the standard Patient Controlled Analgesia (PCA) offered at the Memorial Hermann Hospital - Texas Medical Center.
The PCA drug will be Dilaudid (hydromorphone).
Initial dosing will be per the standard hospital protocol of 0.2 mg demand dose, 10 minute lockout, 2 mg per hour max, 0.4 mg rescue dose.
Adjustments to the PCA dosing will be made based on clinical needs.
Patients will receive PCA until the third postoperative day
|
Active Comparator: Regular Bupivacaine
Patients in this group will receive will receive the standard regular bupivacaine hydrochloride (HCl) and PCA.
Bupivacaine HCl is an FDA-approved injectable suspension.
The standard non-liposomal bupivacaine will be from Hospira pharmaceuticals

Participants will receive 125mg of bupivacaine hydrochloride (equivalent of one 0.25% 50ml or five 0.25% 10ml vials ) diluted in 30ml of preservative-free normal (0.9%) sterile saline for a total volume of 80mL.
Drug will be administered at the end of the procedure just prior to wound closure.
