Study Details

Brief summary:

The purpose of this study is to assess pharmacokinetics of liposomal bupivacaine (Exparel) after multilevel intercostal injections of this local anesthetic for pain control during and after thoracoscopic surgeries.

The specific aim of this study is to evaluate plasma concentration of bupivacaine after intraoperative intercostal injections of 266 mg of liposomal bupivacaine and compare it to plasma concentrations of bupivacaine after intercostal injections of 2mg/kg of 0.5% plain Bupivacaine with maximal dose of 30 ml or 150 mg.

The hypothesis of the study is that plasma concentration of bupivacaine after intercostal injections of 266 mg of liposomal bupivacaine will be similar to concentrations after injections of plain bupivacaine, and will remain below the toxic level threshold range of 2000-3000 ng/mL (2-3 mg/L) at which central nervous system and cardiovascular adverse events would be expected to occur.

The secondary objective is to evaluate if intercostal injections of 266 mg of liposomal bupivacaine will significantly reduce opioid consumption and postsurgical pain, within the first 48 hours and up to 3 months after minimally invasive thoracic surgeries, to determine if both acute and chronic post-thoracotomy pain can be decreased by intraoperative intercostal injections of liposomal bupivacaine.

Additionally, the rate of pneumonia, the rate of atrial fibrillation and length of hospital stay will be assessed as secondary outcomes after thoracic surgeries. These outcomes can be affected by the level of postoperative pain and inflammation.

Significance of this study: If positive, the results of this research have the potential to significantly improve pain management after thoracoscopic surgery.

Based on prior experience, prolonged analgesia after liposomal bupivacaine injection is safe, and may help reduce perioperative opioid consumption and decrease opioid related complications. It will improve patient comfort, eliminate need for indwelling neuraxial catheters and risks associated with them.

Interventions and Outcome Measures

Arms

experimental: Exparel

Intercostal injection of 266mg of Exparel diluted to 30 ml.

active comparator: Bupivacaine

Intercostal injection of 0.5% Bupivacaine 2 mg/kg dose diluted to 30 ml.

Interventions

Exparel

The intercostal blocks will be performed at several levels corresponding to the incisions and chest tube insertion sites + two levels above and two levels below the incisions. On average, 5-6 intercostal spaces will be injected with 4-5 ml of local anesthetic at each level.

Bupivacaine

The intercostal injections of 0.5% Bupivacaine 2 mg/kg dose diluted to 30 ml total will be performed at several levels corresponding to the incisions and chest tube insertion sites + two levels above and two levels below the incisions.

Primary outcome measure

  • Plasma concentration of bupivacaine [ Time Frame: 0.5, 1, 2, 4, 8, 12, 24, 32, 48, 72 hours after intraoperative multiple level intercostal injections. ]
