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 where each line crosses the spine. The goal is to determine if the ASIS line provides a more consistent and reliable estimation of lumbar levels compared to Tuffier's line.",[25,26],"Spinal Anesthesia Evaluation","Lumbar Vertebrae",[28,29,30,31,32],"vertebral level","Ultrasound","Tuffier's line","ASIS","Lateral decubitus position","NOT_YET_RECRUITING","2026-01-30",{"date":36,"type":37},"2026-02-09","ACTUAL",{"date":39,"type":21},"2026-02-20",{"date":41,"type":21},"2028-02-20",{"name":43,"class":44},"Kangbuk Samsung Hospital","OTHER",{"id":46,"slug":47,"hasResults":11,"nctId":48,"briefTitle":49,"officialTitle":50,"acronym":4,"eligibilityCriteria":51,"healthyVolunteers":52,"sex":16,"minAge":17,"maxAge":53,"enrollmentInfo":54,"targetDuration":4,"studyType":56,"phases":57,"briefSummary":59,"conditions":60,"keywords":61,"overallStatus":33,"whyStopped":4,"lastUpdateSubmitDate":66,"lastUpdatePostDateStruct":67,"startDateStruct":69,"completionDateStruct":71,"leadSponsor":73,"locationsCount":76},"100575242","phase-4-the-prolonging-effect-of-dexmedetomidine-on-spinal-anesthesia-through-different-routes-if-administrations-100575242","NCT06769737","The Prolonging Effect of Dexmedetomidine on Spinal Anesthesia Through Different Routes if Administrations","The Prolonged Effects of Spinal Dexmedetomidine Versus Intravenous Dexmedetomidine on Spinal Anesthesia With Isobaric Bupivacaine: A Comparative Study","Inclusion Criteria:\n\n* Male and female patients in adult age group more than 18 years old\n* ASA classification I, II, and III.\n* Orthopedic surgery, including total hip replacement (THR) and total knee replacement (TKR).\n* No history of Obstructive sleep apnea\n\nExclusion Criteria:\n\n* Patient below 18 years old of both genders.\n* ASA classification of IV and more.\n* Patients with a height of less than 150 cm.\n* Patients on alpha-two antagonist ACE inhibitors and CCB.\n* Patient received intrathecal morphine, intravascular dexamethasone, or Midazolam\n* Patient who can't tolerate fluid challenge.
