ReviewCurrent devices used for the monitoring of injection pressure during peripheral nerve blocks.
Peripheral nerve blocks are generally safe. However, there is a small but real associated risk of needle-related complications such as nerve injury. Nerve injury has been associated with high pressure injections in animals, and some data supports the use of monitors to limit injection pressure during these procedures. ⋯ While each of the reviewed methods has its advantages and drawbacks, all of the means of injection pressure monitoring are relatively simple and inexpensive to perform. More outcomes data are required to demonstrate a reduction in injury with their use.
