Summary

This study will describe postoperative pain management for spine surgery patients receiving liposomal bupivacaine (Exparel®) compared to patients not receiving the drug.

Description

This study will describe postoperative pain management for spine surgery patients receiving liposomal bupivacaine (Exparel®) compared to patients not receiving the drug. It is a prospective, randomized clinical trial with two cohorts: Group A: standard of care (SOC) plus liposomal bupivacaine (n=30) and Group B: SOC (n=30). All subjects will undergo open single-level posterior decompression and instrumented fusion for degenerative spondylolisthesis. The surgery is not an experimental procedure. Prior to closing the surgical wound, liposomal bupivacaine will be administered to Group A. The administration of the drug is a study procedure, but note that this is an indicated use of the drug. Postoperatively, subjects will be assessed for pain and opioid consumption. The investigator's hypothesis for statistical analysis is that there will be a 30% decrease in pain medication requirement for the experimental group (Group A: Liposomal bupivacaine ) versus the control group (Group B: No Liposomal bupivacaine).

Eligibility

Yes No Not Sure

Inclusion Criteria

Has a primary diagnosis of single-level lumbar stenosis, disc herniation, and/or spondylolisthesis excluding degenerative disc disease
Receives open, one-level posterior spinal fusion

Exclusion Criteria

Is opioid-tolerant. Opioid tolerant patients are receiving, for one week or longer, at least 60 mg oral morphine/day, 25 mcg transdermal fentanyl/hour, 30 mg oral oxycodone/day, 8 mg oral hydromorphone/day, 25 mg oral oxymorphone/day, or an equianalgesic dose of another opioid
Experienced intraoperative complications (i.e., a dural tear or durotomy). Intra- and post-operative data will be excluded from the analysis for these patients
Has severe liver disease. Bupivacaine is primarily metabolized in the liver via conjugation with glucuronic acid. Patients with liver disease, especially severe disease may be more susceptible to toxicity
Has severe renal disease. Bupivacaine and the metabolite are primarily excreted by the kidneys. Excretion can be significantly changed by urinary perfusion, the presence of renal disease, factors affecting urinary pH, and renal blood flow
Is less than 18 years old
Is pregnant
Cannot read and speak English
