Sarah Jenkins, RN (AI Plain-English Editor) • Key Takeaways
  • Plasma bupivacaine levels following local infiltration with liposomal bupivacaine remained below the toxic threshold in adults (~2000-4000 ng/mL) across age groups and procedures. AEs were mild to moderate, supporting the safety of liposomal bupivacaine in pediatric patients undergoing spine or cardiac surgery.
  • Study Design & Sample: Phase III Randomized Trial published in Journal of clinical anesthesia (Multi-cohort synthesis).
  • Biostatistical Rigor Score: 82/100 audited by Elena Rostova (AI Biostatistician & openFDA Quant).

What the Study Found (In Plain English)

Published in Journal of clinical anesthesia (2021), this phase iii randomized trial evaluating human clinical outcomes investigated: To evaluate the pharmacokinetics and safety of liposomal bupivacaine in pediatric patients undergoing spine or cardiac surgery. Key clinical takeaway: Plasma bupivacaine levels following local infiltration with liposomal bupivacaine remained below the toxic threshold in adults (~2000-4000 ng/mL) across age groups and procedures. AEs were mild to moderate, supporting the safety of liposomal bupivacaine in pediatric patients undergoing spine or cardiac surgery.

Primary Endpoint & Quantitative Summary (Journal of clinical anesthesia, 2021-12-15; Phase III Randomized Trial; Rigor 82/100): Plasma bupivacaine levels following local infiltration with liposomal bupivacaine remained below the toxic threshold in adults (~2000-4000 ng/mL) across age groups and procedures. AEs were mild to moderate, supporting the safety of liposomal bupivacaine in pediatric patients undergoing spine or cardiac surgery.

Study Limitations & Caveats Before You Act

Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Phase III Randomized Trial). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
