Brief Summary
This Phase 1, multicenter, open-label, randomized, bupivacaine-controlled study is designed to evaluate the pharmacokinetics (PK) and safety of EXPAREL vs. bupivacaine HCl for postsurgical analgesia in pediatric subjects aged 0 to less than 6 years of age undergoing cardiac surgery, utilizing local infiltration analgesia (LIA).

Eligibility Criteria
You may qualify if:
- Pediatric participants with congenital heart defects planned to undergo cardiac surgery with cardiopulmonary bypass
- Male or female participants from 0 to less than 6 years of age on the day of surgery: 2 years to less than 6 years of age for Part 1; 6 months to less than 2 years of age for Part 2; 0 to less than 6 months of age for Part 3
- American Society of Anesthesiologists (ASA) Classes 1 through 4.
- Parent/guardian is able to speak, read, and understand the language of the ICF and provide informed consent for the participant.
- Parent/guardian is able to adhere to the study visit schedule and complete all study assessments for the participant.
You may not qualify if:
- History of hypersensitivity or idiosyncratic reactions or contradictions to EXPAREL, bupivacaine HCl, or other amide-type local anesthetics or to opioid medications
- Administration of EXPAREL or bupivacaine HCl within 30 days prior to IP administration
- Administration of an IP within 30 days or 5 elimination half-lives of such IP, whichever is longer, prior to IP administration, or planned administration of another IP or procedure during participation in this study
- History of preterm birth (before 35 weeks of pregnancy)
- History of coagulopathies or immunodeficiency disorders
- Disease or condition that, in the opinion of the Investigator, indicates an increased vulnerability to IPs and/or procedures
- Recent or potential exposure to COVID-19
- Cardiac surgery has been canceled and cannot be rescheduled within 30 days of signing the ICF because of any reason.
- Necessity in delayed wound closure
- Informed consent withdrawn before randomization
