Cesarean delivery is the most common in-patient surgery performed in the United States. Opioids are frequently prescribed post-operatively; this can lead to misuse or even illegal distribution.
We infiltrated liposomal bupivacaine at the time of fascial closer of a Pfannenstiel incision, during a cesarean section. An 80cc solution was divided into four infiltrates of 5cc of Liposomal Bupivacaine, 6cc of .5% Bupivacaine and 9cc of Normal Saline each. Half of the solution was injected laterally under the fascia and the remaining was distributed evenly subcutaneously. Post-operative management was standardized with intrathecal morphine, scheduled Ketorolac and Ofirmev for the first 24 hours intravenously. Scheduled PO ibuprofen and acetaminophen were continued for forty-eight hours postoperatively. Oxycodone was ordered as needed but not scheduled. We used our SeamlessMD smartphone application to collect data on pain control and patient satisfaction. We reviewed in-patient charts and outpatient EMR records post-operatively for two weeks
Of the 11 cases, five patients used no narcotics, and one outlier was identified as a potential abuser. The mean morphine equivalent was 7.5mg or one 5mg oxycodone over the inpatient and 2 week post-operative period. The average length of stay was 2.2 days. The response rate was 42% to patient satisfaction questions.
Liposomal Bupivacaine reduces opioid use in the post- operative time period for cesarean section. It increased patient satisfaction and improved pain control, shortening length of stay. Further randomized control studies to determine the best delivery method are warranted.
