Capogna E, et al. - As the CompuFlo epidural system has been recently proposed and confirmed as an objective as well as a sensible tool to identify the epidural space, researchers focused on validating if the high sensitivity of the tool may assist the anesthesiologist to detect the epidural space very early, restricting the extension of the Tuohy needle into the epidural space. For this purpose, they undertook this prospective, simulation study, wherein, they assessed the Tuohy needle extension through a simulated ligamentum flavum during the epidural procedure done by 52 expert anesthesiologists by utilizing the CompuFlo epidural instrument or their standard loss of resistance to saline technique (LORT). The mean (SD) needle extension length was estimated to be 3.90 (3.71) mm and 0.68 (0.46) mm in the standard technique group and in the CompuFlo group, respectively. Puncturing high-resistance material that simulated the ligamentum flavum, a more precocious determination of the arrest of the needle was provided by CompuFlo vs traditional LORT.
