Summary
Selective spinal anesthesia is widely used for ambulatory surgery. Unilateral spinal
anesthesia is a suitable option for ambulatory anesthesia as it is efficient and effective.
Lidocaine has been the well-known choice for this procedure. However, it is associated to
transient neurologic symptoms (TNS). Different anesthetic strategies for this procedure have
been performed, for example, the use of small doses of long-acting agents and the use of
additives such as opioids. The ideal local anesthetic should be lidocaine-like without risk
of transient neurologic symptoms. We design and plan a randomised clinical trial to show if
hyperbaric prilocaine 2% would be an alternative.
