However, the current blind palpation landmark technique is known to be highly inaccurate and may increase the risk of multiple insertion attempts, patient suffering and complication rates such as spinal cord injury. Various clinical studies have confirmed the effectiveness of ultrasound imaging compared with the traditional palpation method. However, none of the present system can achieve real-time guidance.\n\nThe overall aim of this proposal is to develop an ultrasound guided automated spinal landmark identification with real-time neuraxial needle insertion system (uSINE) to improve patient safety and efficacy of neuraxial procedure needle insertion success. This will be achieved in 4 phases of technology development and clinical trial phases. The investigators will recruit 20 subjects in a prospective cohort study to investigate the spinal needle first attempt success rate as a clinically relevant outcome. The secondary aim is to develop an automated spinal landmark identification algorithm using image processing to identify spinal landmarks in 50 obese patients. Third phase objective will be to obtain clinical data, and evaluation and annotation of the clinical data of spinal ultrasonography in 65 obese patients (BMI \\> 30kg\u002Fm2), whereas the fourth phase will measure the uSINE identification accuracy and first-attempt puncture success rate of uSINE in a clinical study of 65 obese patients (BMI \\> 30kg\u002Fm2).",[28,29],"Spinal Anaesthesia","Obesity",[31,32,33],"spinal anaesthesia","Neuraxial ultrasonography","landmark identification","RECRUITING","2026-08-04",{"date":37,"type":38},"2026-08-07","ACTUAL",{"date":40,"type":38},"2018-05-24",{"date":42,"type":22},"2027-12-31",{"name":44,"class":45},"KK Women's and Children's Hospital","OTHER_GOV",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":4,"eligibilityCriteria":53,"healthyVolunteers":11,"sex":54,"minAge":55,"maxAge":55,"enrollmentInfo":56,"targetDuration":4,"studyType":23,"phases":58,"briefSummary":59,"conditions":60,"keywords":4,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":63,"lastUpdatePostDateStruct":64,"startDateStruct":66,"completionDateStruct":68,"leadSponsor":70,"locationsCount":5},"100625749","should-anaesthesiologists-be-taught-to-perform-ultrasound---assisted-neuraxial-access-in-spinal-anaesthesia-100625749","NCT07426679","Should Anaesthesiologists Be Taught to Perform Ultrasound-- Assisted Neuraxial Access in Spinal Anaesthesia?","Should Anaesthesiologists Be Taught to Perform Ultrasound-- Assisted Neuraxial Access in Spinal Anaesthesia?-Protocol of a Randomised Controlled Study","Inclusion Criteria:\n\n* Physicians will be included using the following inclusion criteria:\n\n  1.

Preprocedural ultrasound may improve identification of the optimal injection site, yet its use in clinical practice remains limited, partly due to a lack of structured training.\n\nThis multicentre randomised controlled trial investigates whether anaesthesiologists performing ultrasound-assisted spinal anaesthesia achieve better clinical outcomes and higher patient satisfaction compared with the traditional manual palpation technique. Both novice anaesthesia residents and more experienced anaesthesiologists are included.\n\nParticipants receive structured simulation-based training using either ultrasound-assisted or manual palpation techniques, following a mastery learning approach with predefined performance standards. After certification, participants perform spinal anaesthesia during elective lower limb surgery, with clinical performance assessed by senior anaesthesiologists.\n\nThe primary outcome is first-attempt success of spinal block. Secondary outcomes include number of attempts, needle redirections, time spent, need for assistance, and overall block success. Patient satisfaction and complications are assessed as tertiary outcomes.\n\nThis study aims to provide evidence on the clinical effects of structured training in ultrasound-assisted neuraxial access and to explore the role of prior clinical experience.",[61,28,62],"Ultrasound","Simulation Based Medical Education","2026-02-16",{"date":65,"type":38},"2026-02-23",{"date":67,"type":38},"2026-02-01",{"date":69,"type":22},"2026-12-31",{"name":71,"class":72},"University of Southern Denmark","OTHER"]
