The Effect of Spinal Flexion in the Lateral Decubitus Position on the Unilaterality During Spinal Anesthesia

NCT ID: NCT01321684

Last Updated: 2012-05-30

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 32 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2011-03-31
• Study Completion Date: 2011-10-31

Brief Summary

For unilateral spinal block, spinal local anesthetics should take effect on the spinal nerves of one side. With full flexion of the spine, the cauda equina becomes tightened and hangs in the middle of the subarachnoid space. This study was performed to assess if flexion of the vertebral column facilitates unilateral spinal anesthesia.

Conditions

Spinal Anesthesia

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: SUPPORTIVE_CARE
• Blinding Strategy: SINGLE

Interventions

lateral decubitus position with full spinal flexion

The patients maintained the lateral decubitus position with the hips and back fully flexed for 15 minutes.

Intervention Type: OTHER

lateral decubitus position without spinal flexion

the patients are allowed to straighten their flexed hips and back to obtain the normal lordotic curvature of spinal column

Intervention Type: OTHER
