About

A prosperous neuraxial anesthesia positioning ensures a raised chance of successful needle placement. The primary aim is to compare "Sitting Cross-legged Fetal Position -SCF" with "Lateral Decubitus Fetal Position-LDF" anatomically via sonography.

Secondary aim is to compare their comfort.

Full description

Fifty participants were included to this prospective, randomized, consecutive controlled clinical study. Six parameters were evaluated in each position; subcutaneous tissue (ST), skin to spinous process (S-SP), transverse diameters of bilateral paraspinal muscles (left paraspinal muscle [LPM] and right paraspinal muscle [RPM]), interspinous gap opening (ISGO), mean of bilateral paraspinal muscles (MPM). The change of every measurement recorded via ultrasonography (USG) according to the positioning techniques were also calculated. The calculations are explained briefly in primary outcomes (including the change of SCF-LDF in ST, S-SP, LPM, RPM, MPM, ISGO). Stretcher comfort (SC), position comfort (PC), lumbar comfort (LC), and abdominal comfort (AC) were evaluated by the participants with the 7-point Numerical Rating Scale (NRS).

50 participants in 2 patient groups

The LDF neuraxial positioning technique

Active Comparator group

Description:

In the LDF neuraxial positioning technique, fifty participants were planned to lay down the stretcher facing the wall of the sonography room and turned back to the consultant Radiologist. Volunteers jaw touch to chest and legs in abdominal flexion with hands are on the knees. The position is completed with the back curved in the fetal position. Then the USG is performed by the consultant Radiology M.D. in maximum 2 hours time to each participant, and the 7-point NRS evaluation is done by each participant in maximum 30 minutes time until the study ends within 15 weeks.

Procedure: Anatomical intervention with USG and comfort evaluation with NRS

The SCF neuraxial positioning technique

Experimental group

Description:

In the SCF neuraxial positioning technique, the same fifty participants were planned to sit on the same part of the stretcher facing the wall of the sonography room and turned back to the consultant Radiologist with legs crossed, forearms of the participants are on the lap and hands are on the knees, and the position is completed with the back curved in the fetal position.Then the USG is performed by the consultant Radiology M.D. in maximum 2 hours time to each participant, and the 7-point NRS evaluation is done by each participant in maximum 30 minutes time until the study ends within 15 weeks.
