RT Journal Article SR Electronic T1 Comparison of Epidural Lidocaine and Bupivacaine-Fentanyl Mixture for Extracorporeal Shock Wave Lithotripsy JF Regional Anesthesia: The Journal of Neural Blockade in Obstetrics, Surgery, & Pain Control JO Reg Anesth Pain Med FD BMJ Publishing Group Ltd SP 72 OP 76 DO 10.1136/rapm-00115550-198813020-00006 VO 13 IS 2 A1 David Gissen A1 Laura Fraser Wong A1 Maud Naroll YR 1988 UL http://rapm.bmj.com/content/13/2/72.abstract AB Epidural opiates alone do not provide sufficient anesthesia for most surgical procedures. Combined with local anesthetics, however, they are valuable in treating postoperative and labor pain. Two groups of patients were compared (n = 21) who underwent extracorporeal shock wave lithotripsy (ESWL). One group was given a local anesthetic, lidocaine, and the other was given a local anesthetic-opiate combination, bupivacaine-fentanyl. In each group, adequate levels of analgesia were obtained. The bupivacaine-fentanyl mixture produced significantly less motor block. Its disadvantages were a longer onset time and occasional itching. This small series confirms the clinical value of a low-dose epidural bupivacaine-fentanyl mixture as an alternative to lidocaine for use in ESWL, and suggests that greater use be made of this mixture.
