U.S., Feb. 10 -- ClinicalTrials.gov registry received information related to the study (NCT07396961) titled 'Consistency of ASIS Line vs. Tuffier's Line for Lumbar Level Identification' on Jan. 30.
Brief Summary: Tuffier's line is commonly used as a landmark for estimating lumbar vertebral levels during spinal anesthesia. However, its accuracy can vary depending on factors such as age, sex, BMI, and posture. This study evaluates the consistency of an alternative landmark, the "ASIS line" (a line connecting both Anterior Superior Iliac Spines), for identifying lumbar levels in the lateral decubitus position. Researchers will mark both the ASIS line and Tuffier's line on participants and use ultrasound to verify the exact vertebral level whe...
