“…I use 1.0-1.2 ml of isobaric levobupivacaine 0.5% (5-6 mg), plus 20 lg of fentanyl, made up to a total volume of 3.0 ml with saline, using a double-check procedure previously described [7]. Intrathecal injection is in the lateral position, with the operated side uppermost, contrary to the ASAP1 recommendations [3]. This is more comfortable for positioning the patient than having the operated side downwards, to facilitate a hyperbaric technique.…”
