Dose-response relationship between local anesthetic volume and hemidiaphragmatic paresis following ultrasound-guided supraclavicular brachial plexus blockade.
There is no consensus regarding what volume of local anesthetic should be used to achieve successful supraclavicular block while minimizing hemidiaphragmatic paresis (HDP). This study investigated the dose-response relationship between local anesthetic volume and HDP after ultrasound-guided supraclavicular brachial plexus block. ⋯ There is no clinically relevant volume of local anesthetic at which HDP can be avoided when performing a supraclavicular block. In our subject population free of respiratory disease, HDP was well tolerated.

Fluoroscopically guided mandibular nerve block: a modified lateral approach.
Mandibular nerve blocks are indicated for atypical face pain and trigeminal neuralgia. We hypothesized that a modified lateral approach, which entailed a combination of lateral and anterior approach techniques to the mandibular nerve block would lead to similar efficacy and improved safety profile rather than the typical lateral or anterior techniques. ⋯ The modified lateral approach to a mandibular nerve block avoids the respective risks associated with either the lateral and anterior approach. Facial intervention techniques typically pose increased safety challenges, however through cadaveric anatomic reconstruction, we have developed a safer approach for mandibular nerve blockade.
