Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Ultrasound has emerged as an useful tool for neuraxial blockade. The aim of this study is to compare the efficacy and safety between the midline approach and paramedian approach for ultrasound-assisted spinal anesthesia in adult patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Midline group

Preprocedural ultrasound-assisted midline approach of spinal anesthesia will be performed. 0.5% heavy bupivacaine will be injected to intrathecal space for spinal anesthesia.

Group Type EXPERIMENTAL

ultrasound-assisted midline approach

Intervention Type PROCEDURE

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 midline approach.

Paramedian group

Preprocedural ultrasound-assisted paramedian approach of spinal anesthesia will be performed. 0.5% heavy bupivacaine will be injected to intrathecal space for spinal anesthesia.

Group Type ACTIVE_COMPARATOR

ultrasound-assisted paramedian approach

Intervention Type PROCEDURE

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.
