Lap-assisted vs. US-Guided Visualization of TAP Blocks

Not Recruiting

Trial ID: NCT04226300


Peripheral nerve blocks have been effective in decreasing post-operative pain as well as the use of narcotics for numerous years. Typically, these blocks are placed by anesthesiologist via ultrasound. In more recent years, surgeons have been placing nerve blocks laparoscopically. Since there are few studies that looks compare the two techniques we aim to perform a randomized control trial to demonstrate if a laparoscopic placed nerve block is as efficient and accurate as an ultrasound placed block.
