abbreviations. You may need to refer to the discussion of abbreviations in Chapter 7 and
to a list of abbreviations and a style guide. Prepare a style sheet if there are options.*
a. When the electrode is fully in the spinal cord tissue, the resistance shoots up to 1000-ohms or
more.
b. There are two methods of applying a coagulating current. One uses a fixed time, eg. 30 sec,
and varies the power applied, eg, 5-mA, then 10mA, 15mA, etc, up to a limit given by the
manufacturer. The other method fixes the power, eg at 30 mA, and varies the time, eg 5 sec,
then 10 seconds, 15 sec, etc.
c. The spinal cord at the C1-C2 level is about 15-MM across and 10- to 12-mm from front to
back, so the maximum lesion needed is 6 mm x 4 mm. Furthermore, a cylindrical electrode
with a 2-mm uninsulated tip will provide a lesion somewhat barrel shaped; an exposed tip of
3-mm. is also used and will provide a lesion of about 4.5 x 3.0 mm.
