However, the key determinants of procedural success lie in the accurate intraoperative identification of proper LBB lead positioning and the prevention of cardiac perforation. Our previous research has established a methodology for Lumenless Lead (LLL) implantation under the guidance of continuous pacing monitoring, and this methodology has been further adapted for Stylet-driven Lead (SDL) implantation. The present study is designed as a multicenter, randomized controlled trial, aiming to compare the differences in efficacy and safety between LLL and SDL during LBBP procedures guided by continuous pacing monitoring, with the presence of S-V dissociation serving as the criterion for confirming optimal LBB lead positioning.",[26,600],"Conduction Block, Atrioventricular","2026-01-31",{"date":603,"type":38},"2026-02-03",{"date":605,"type":21},"2026-01-24",{"date":491,"type":21},{"name":608,"class":158},"Ningbo No.2 Hospital",{"id":610,"slug":611,"hasResults":12,"nctId":612,"briefTitle":613,"officialTitle":614,"acronym":615,"eligibilityCriteria":616,"healthyVolunteers":12,"sex":18,"minAge":617,"maxAge":243,"enrollmentInfo":618,"targetDuration":4,"studyType":90,"phases":619,"briefSummary":622,"conditions":623,"keywords":626,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":631,"lastUpdatePostDateStruct":632,"startDateStruct":634,"completionDateStruct":636,"leadSponsor":638,"locationsCount":184},"100609984","phase-2-comparison-of-supra-vs-infra-inguinal-fascia-iliaca-blocks-for-spinal-positioning-and-analgesia-in-lower-limb-surgery-100609984","NCT07221682","Comparison of Supra vs Infra Inguinal Fascia Iliaca Blocks for Spinal Positioning and Analgesia in Lower Limb Surgery","Comparison For Ease Of Spinal Positioning & Duration Of Post-Op Analgesia Between Ultrasound Guided Supra-Inguinal Fascia Iliaca Block Vs Ultrasound Guided Infra-Inguinal Fascia Iliaca Block In Patients Undergoing Thigh & Knee Surgeries","27G","Inclusion Criteria:\n\n1.

Different modalities to make patient pain free for spinal positioning, post op analgesia and patient satisfaction including supra-inguinal fascia iliaca block (S-FIB) and infra-inguinal fascia iliaca blocks (I-FIB) have been studies.

Depending on the allotted group, patients will be given the block under the guidance of ultrasound in the preoperative area. After block patients will be assessed for ease of spinal positioning using EOSP Scale, postoperative duration of analgesia and patient satisfaction using Likert Scale and data will be recorded on prescribed proforma.\n\nAll the findings will be noted in a specially designed proforma by the researcher.
