Ultrasound-assisted Versus Conventional Landmark-guided Spinal Anesthesia in Patients With Abnormal Spinal Anatomy

• Status: Completed
• Trial end date: 2018-07-05
• Target enrollment: 0
• Participant gender: All

Summary

Spinal anesthesia can be challenging in patients with lumbar scoliosis or previous lumbar spine surgery. This study aims to evaluate whether the use of the ultrasound-assisted spinal anesthesia reduces the number of passes required to successful dural puncture compared with the conventional surface landmark-guided technique in patients with abnormal spinal anatomy.

• Phase: N/A
• Accepts Healthy Volunteers?: No
