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.

Conditions

• Anesthesia, Spinal
• Ultrasonography
• Scoliosis

Interventions

Type	Name	Description
PROCEDURE	Ultrasound-assisted paramedian spinal anesthesia	A preprocedural ultrasound scanning will be done, and skin marking will be made. The needle entry point and insertion angle will be determined based on ultrasound scanning. Spinal anesthesia will be performed via paramedian approach.
PROCEDURE	Landmark-guided spinal anesthesia	Spinal anesthesia will be done using conventional landmark-guided technique.
DRUG	0.5% heavy bupivacaine	0.5% heavy bupivacaine will be administered into intrathecal space. The dose of local anesthetic injected for spinal anesthesia will be at the discretion of the attending anesthesiologist. The dose range of intrathecal bupivacaine will be between 12 and 16 mg.
