简要总结
Patients undergoing breast reconstruction with tissue expanders will be treated with a local anesthetic during their procedure and monitor their post-operative pain level and amount of oral pain medication taken. This information will be used to determine if liposomal bupivacaine provides better and longer pain control vs. bupivacaine HCl.
详细描述
Fifty consecutive (25 per arm) patients undergoing unilateral or bilateral breast reconstruction with tissue expanders will be administered intraoperatively in a standardized manner with either bupivicaine HCl (control group) or liposomal bupivacaine/Exparel (experimental group). Pain will be assessed qualitatively through the use of: 1) numeric rating scale during rest (NRS-R) and activity (NRS-A), 2) brief pain inventory (BPI) questionnaire, and 3) postoperative analgesia patient satisfaction scale. Furthermore, investigators will record the use of rescue analgesics for each patient. This part of the study will provide quantitative data that investigators can then use in comparison to the qualitative measurements (NSR, BPI, patient satisfaction scale rate). In turn, this will allow us to objectify patient's pain, thereby increasing the validity of our results. More importantly, this aspect of the investigation will enable us to study the impact that liposomal bupivacaine has in reducing the postoperative usage of opioid medications in this patient population. As this is a pilot study, a sample size of 50 total patients (25 per treatment group) is planned. This sample size should provide estimates of potential effect sizes and variability in the present setting to allow for future study planning. This study should provide adequate evidence of whether pain decreases of 15% or more are unlikely in this setting.
Investigators aim to evaluate the effectiveness of DepoFoam Bupivicaine (Exparel®) to reduce postoperative pain in breast reconstruction patients compared to the current standard treatment (bupivacaine HCl). Investigators hypothesize that patients undergoing breast reconstruction with tissue expander will achieve greater control of post-operative pain and longer lasting analgesia with the use of liposomal bupivacaine.

60 Hour Pain Assessment Numeric Rating Scale During Rest
时间窗: 60 hours post-operatively
Pain will be assessed qualitatively through the use of numeric rating scale during rest (NRS-R). The higher scores indicate more severe pain during rest (10 meaning the worst pain, 0 meaning no pain) The range is 0 to 10.
72 Hour Pain Assessment Numeric Rating Scale During Rest
时间窗: 72 hours post-operatively
Pain will be assessed qualitatively through the use of numeric rating scale during rest (NRS-R). The higher scores indicate more severe pain during rest (10 meaning the worst pain, 0 meaning no pain) The range is 0 to 10.
24 Hour Pain Assessment Numeric Rating Scale During Rest
时间窗: 24 hours post-operatively
Pain will be assessed qualitatively through the use of numeric rating scale (0-10) during rest (NRS-R). The higher scores indicate more severe pain during rest (10 meaning the worst pain, 0 meaning no pain)
36 Hour Pain Assessment Numeric Rating Scale During Rest
时间窗: 36 hours post-operatively
Pain will be assessed qualitatively through the use of numeric rating scale (0-10) during rest (NRS-R). The higher scores indicate more severe pain during rest (10 meaning the worst pain, 0 meaning no pain)
