Meta Analysis
Effect of Adding Dexmedetomidine to Local Anesthetic Agents for Transversus Abdominis Plane Block: A Meta-analysis.
Dexmedetomidine (Dex) has been used as an adjuvant in transversus abdominis plane (TAP) blocks. This meta-analysis was aimed at evaluating the effect of Dex in TAP blocks. ⋯ The addition of Dex to LAs in the TAP block for analgesia after abdominal surgeries decreased 24-hour opiate use and increased the overall time to rescue analgesia including certain subgroups without increasing adverse events. Its effect on postoperative pain scores was not as definitive.

ReviewFunctional anatomy of the nerve and optimal placement of the needle for successful (and) safe nerve blocks.
Summarize the current thinking concerning the clinically relevant aspects of nerve anatomy and best injection sites for nerve blocks. ⋯ It is necessary to have a better understanding of what intraneural injection is when dealing with any type of nerve blocks, be that single nerve, plexuses, or the sciatic nerve. Perineural injections provide successful anesthesia without putting the nerve integrity at risk. That practice is supported by years of experience and common sense. Currently, there is no evidence to support any kind of intraneural injections, intrafascicular or extrafascicular.
