Background The patient's position during spinal anesthesia administration plays a major
role in the success of spinal needle insertion into the subarachnoid space. The traditional
sitting position (TSP) is the standard position for spinal anesthesia administration, but the
success rate for spinal anesthesia administration in the TSP is still quite low. The crossed-
leg sitting position (CLSP) is one of the alternative positions for the administration of spinal
anesthesia, which can increase the degree of lumbar flexion. Objectives This study aimed to …

Introduction: Spinal anesthesia is widely utilized in surgical procedures due to its
effectiveness and lower risk compared to general anesthesia. Proper needle placement is
crucial for successful anesthesia administration and to minimize complications. Patient
positioning plays a significant role in needle placement, with the crossed-leg sitting position
emerging as a potential alternative to the traditional seated posture. However, empirical
research comparing the efficacy of these positions, particularly in urology surgeries, is …
