Observational StudyIntercristal line determined by palpation in parturients in the sitting and the lateral decubitus positions: a prospective observational study.
We aimed to investigate intersected vertebral level changes in the palpated intercristal line (PI-line) when shifting from a sitting to a lateral decubitus position in parturients. ⋯ The intersected segment level of the PI-line, measured with trisected segments in each vertebral interspace, was different between the sitting and the lateral decubitus positions in approximately 80% of the parturients. Notably, 15% (6/39) of the parturients had at least one vertebral interspace deviation.
