Ultrasound-assisted Versus Conventional Landmark-guided Paramedian Spinal Anesthesia in Elderly Patients

• Status: Completed
• Trial end date: 2018-01-11
• Target enrollment: 0
• Participant gender: All

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.
