A New Neuraxial Position Technique " The Anatolian Sitting Position- Sitting Fetal Cross-legged"

A prosperous neuraxial anesthesia positioning ensures a raised chance of successful needle placement. The primary aim is to compare "The Anatolian sitting position-ASP" with "The Sitting Fetal Position-SFP" sonographically. Secondary aim is to compare their comfort.

About this study

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 (the Anatolian Sitting Position [ASP] could also be named as "sitting fetal cross-legged position" and the Sitting Fetal Position [SFP] which is a traditional sitting position) were also calculated. The calculations are explained briefly in primary outcomes (including the change of ASP-SFP 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 5-point Numerical Rating Scale (NRS).
