Unilateral Sensitive Spinal Anesthesia. Case Report

A 46-year-old male was admitted for tenolisys of anterior compartment of lower leg under spinal anesthesia. Spinal puncture was performed with the patient in the lateral left side, in the L3-L4 using 27 G needle, and 4 mg of 0.1% hypobaric bupivacaine were administered. The patient remained in that position for 10 min. In the limb to be operated, the level of sensory block was observed in L1 without motor block. With this new technique that was obtained surgical analgesia, but without motor blockade. We call this new technique of unilateral sensitive spinal anesthesia.
