The second division of the trigeminal nerve can be easily blocked by the intraoral route. The technique presented involves entering the greater palatine foramen, traversing the pterygopalatine canal with a needle, and depositing the local anesthetic solution into the superior aspect of the pterygopalatine fossa, where the trunk of the second division lies after the nerve exits the foramen rotundum. ⋯ This is followed by a discussion of the possible complications as well as their prevention and remedy should they occur. While this is not a new technique, it as been a forgotten one.

A technique for continuous block of the brachial plexus is described using an indwelling teflon cannula positioned according to the anatomical dictates of the supraclavicular and interscalene spaces. The anatomy is presented as key to consistent results. Advantages of a continuous block are an extension of normal block duration, block placement independent of operating times and a possible application to intensive care patients.
