Summary
Multiple passes and attempts during spinal anesthesia might be associated with a greater
incidence of paraesthesia, postdural puncture headache, and spinal hematoma. We hypothesized
that the use of a preprocedural ultrasound-assisted paramedian technique for spinal
anesthesia in patients with old age would reduce the number of passes required to entry into
the subarachnoid space when compared with the landmark-guided paramedian approach. The study
participants will be randomized into group L (landmark-guided) and group U
(ultrasound-assisted). In group L, spinal anesthesia will be performed via paramedian
approach using conventional landmark palpation technique. In group U, a preprocedural
ultrasound scan will be used to mark the needle insertion site, and spinal anesthetic will be
done via the paramedian approach.
