Although previous studies have compared various methods of pain control in these patients, few have compared different local anesthetics. This retrospective analysis compares the use of bupivacaine to its longer-acting form, liposomal bupivacaine, in patients who had undergone pectus excavatum repair with the Ravitch method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods:<\/jats:title>\n                    <jats:p>Eleven patients who received local infiltration with liposomal bupivacaine were matched to 11 patients who received local infiltration utilizing bupivacaine with epinephrine. The primary outcome was total morphine milligram equivalents per kilogram body weight (MME\/kg) over the complete length of hospital stay. Secondary outcomes included total cumulative diazepam, acetaminophen, ondansetron, and NSAID dose per kilogram body weight (mg\/kg) over the course of the hospital stay, chest tube drainage (ml\/kg body weight), number of post-operative hours until the first bowel movement, Haller Index, patient request for magnesium hydroxide, average pain scores from post-operative day 1 to post-operative day 5, and length of hospital stay. Continuous variables were reported as medians with inter-quartile ranges, and categorical values were reported as percentages and frequencies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The total MME\/kg [1.7 (1.2-2.4) vs 2.9 (2.0-3.9),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.007] and hydromorphone (mg\/kg) [0.1 (0.0-0.2) vs 0.3 (0.1-0.4),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.006] use in the liposomal bupivacaine group versus bupivacaine with epinephrine was significantly reduced over total length of hospital stay. Similarly, there was a reduction in diazepam use in the liposomal bupivacaine group versus the bupivacaine group [0.4 (0.1-0.8) vs 0.6 (0.4-0.7),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.249], but this did not reach statistical significance. The total dose of ondansetron (mg\/kg) was not statistically different when comparing the liposomal bupivacaine group to the bupivacaine group [0.3 (0.0-0.5) vs 0.3 (0.2-0.6),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.332]. Interestingly, the total dose of acetaminophen (mg\/kg) was statistically increased in the liposomal bupivacaine group compared to the bupivacaine with epinephrine group [172 (138-183) vs 74 (55-111),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.007]. Additionally, the total chest tube drainage (ml\/kg) was significantly reduced in the liposomal bupivacaine group [9.3 (7.5-10.6) vs 12.8 (11.3-18.5),\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.027]. Finally, the percentage of patients without requests for magnesium hydroxide to promote laxation was significantly higher in the liposomal bupivacaine group than in the bupivacaine group (63.6% vs 18.2%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.027).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The use of liposomal bupivacaine for local infiltration in patients who undergo the Ravitch procedure for pectus repair offers advantages over plain bupivacaine, including reduced opioid consumption and opioid-related side effects.
