Application for ESRA Abstract Prizes: I apply as an Anesthesiologist (Aged 35 years old or less)

Background and Aims Pulsed radiofrequency (RF) is performed for treating several clinical conditions causing chronic pain. There are many variables in its application that are not well established based on the available evidence, voltage being one of them. Voltage can

Methods We have performed a survey to analyse the situation of the use of pulsed RF to treat several clinical conditions causing chronic pain; shared trough the Spanish pain society, 91 people answered it.

Results In trigeminal ganglion, 23/91 use 45V, 15/91 use 65V, 3/91 use 85V and 1/91 use 100V. In stellate ganglion, 31/91 use 45V, 17/91 use 65V and 1/91 use 85V. In cervical medial branch, 27/91 use 45V, 9/91 use 65V and 1/91 use 85V. In thoracic medial branch, 18/91 use 45V, 3/91 use 65V and 2/91 use 85V. In lumbar medial branch, 18/91 use 45V, 8/91 use 65V and 3/91 use 85V. In thoracic dorsal ganglia, 36/91 use 45V and 15/91 use 65V. In lumbar dorsal ganglia, 53/91 use 45V, 19/91 use 65V and 1/91 use 85V. For peripheral nerves (using the suprascapular nerve as an example), 46/91 use 45V, 20/91 use 65V and 1/91 use 85V. For peripheral nerves, 11/91 do not apply control of temperature with pulsed RF. 61% apply the variation of the voltage in the temperature control; 34% apply the variation of the pulse width in the temperature control.

Conclusions There is lot of variability in applying different voltages in pulsed radiofrequency for several clinical conditions; we need better evidence to stablish the best voltage for any indication.
