Clinical Trial Summary

The overall purpose of this study is to evaluate the analgesic efficacy of liposomal bupivacaine in optimizing pain control, minimizing the risk of postoperative nausea and vomiting (PONV), and improving recovery after abdominoplasty. This will be done by comparing intraoperative abdominal wall and incisional injection of bupivacaine to bupivacaine plus liposomal bupivacaine in 46 participants 18 years and older undergoing elective abdominoplasty. This will be studied using pain assessments, validated surveys, medication logs and review of medical records.

Description:

Postoperative pain, nausea, and vomiting can be frustrating sequelae of elective surgery. Poorly managed postoperative pain can lead to increased opioid use, increased postoperative nausea and vomiting (PONV), delayed return to work and usual activities, unplanned hospital admissions, surgical complications, and patient dissatisfaction. In light of the growing opioid epidemic in the United States, any intervention that potentially minimizes opioid use may have meaningful individual and societal impact. Despite the use of multiple techniques for managing postoperative pain in abdominoplasty patients, pain control continues to be a challenge for this patient population.

One technique commonly employed to improve pain control is the use of abdominal wall and incisional injection of local anesthetic agents to block the sensory nerves supplying the anterior abdominal wall and abdominal incisions in order to decrease sensation and pain in the abdomen in the setting of abdominoplasty surgery. Local anesthetic often used in this procedure is bupivacaine (Marcaine) ± epinephrine. However, in 2012, a liposomal bupivacaine suspension (Exparel; Pacira BioSciences, Inc, San Diego, California) was introduced as a longer-acting local anesthetic used for management of postoperative pain. At the University of Wisconsin, patients undergoing abdominoplasty routinely receive intraoperative injection of local anesthetic to the abdominal wall and abdominal incisions, using bupivacaine as the local anesthetic, along with standard multimodal perioperative pain management including cool compresses, non-steroidal anti-inflammatories (NSAIDs), acetaminophen, and opioids.

The overall purpose of this study is to evaluate the analgesic efficacy of liposomal bupivacaine in optimizing pain control, minimizing the risk of PONV, and improving recovery after abdominoplasty. This will be done by comparing intraoperative abdominal wall and incisional injection of bupivacaine to bupivacaine plus liposomal bupivacaine in patients undergoing abdominoplasty. This will be studied using pain assessments, validated surveys, medication logs and review of medical records.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Opioid use at 24 hours	Amount of opioids used postoperatively, measured in morphine equivalents	24 hours postoperatively
Secondary	Quality of Recovery-40 (QOR-40) Score	The QOR-40 is a 40 item survey about the quality of recovery with a total possible range of scores from 40 to 200 where the higher the score the higher quality the recovery.	24 hours postoperatively
Secondary	Pain score Postoperative Day 1 (POD 1)	The pain survey is scored on a 0-10 scale where 0 is no pain and 10 is the worst possible pain.	24 hours postoperatively
Secondary	Pain score 1 week postop	The pain survey is scored on a 0-10 scale where 0 is no pain and 10 is the worst possible pain.	1 week postoperatively
Secondary	Opioid use at 1 week	total opioid used, measure in morphine equivalents	1 week postoperatively
Secondary	Antiemetic use POD 1	total antiemetic used	24 hours postoperatively
Secondary	Antiemetic use 1 week	total antiemetic used	1 week postoperatively
Secondary	Incidence of postoperative nausea and vomiting	Incidence of postoperative nausea and vomiting, as measured by frequency of emesis reported by the patient, and subjective feeling of nausea.	24 hours postoperatively
Secondary	Incidence of postoperative complications	Incidence of postoperative complications	1 week postoperatively
