The use of intravenous lidocaine in patients undergoing outpatient gynecologic laparoscopy improves the quality of recovery after surgery and reduces the need for opioids, according to a randomized, double-blind clinical trial. Investigators at Northwestern University, who conducted the study, said clinicians should consider using IV lidocaine for a variety of ambulatory procedures.

“I would recommend that it [IV lidocaine] be used routinely in outpatient surgeries,” said Gildasio De Oliveira Jr., MD, assistant professor of anesthesiology at Northwestern University Feinberg School of Medicine, in Evanston, Ill., who helped conduct the research. “It should work for surgeries that have the same pain profile.” Dr. De Oliveira’s group presented its findings at the 2012 annual meeting of the Society for Ambulatory Anesthesia (abstract E3) and published their results in Anesthesia and Analgesia (2012;115:262-267).

Although IV lidocaine has been shown to be effective at reducing postoperative pain in patients undergoing inpatient surgeries such as colon resections, it is rarely used for outpatient surgeries. Before this clinical trial, the only study testing perioperative IV lidocaine in ambulatory surgery patients demonstrated that the drug reduced postoperative pain and opioid consumption in the postanesthesia care unit, but did not lead to a faster discharge from the hospital or reduce opioid consumption after discharge (Anesth Analg 2009;109:1805-1808).
