Elevated Lateral Position Improves the Success of Paramedian Approach Subarachnoid Puncture in Spinal Anesthesia before Hip Fracture Surgery in Elderly Patients: A Randomized Controlled Study

Three-dimensional pelvis computed tomography-assisted Taylor approach for spinal anesthesia in hip arthroplasty: a retrospective study

“…The success rate of the 3D pelvis CT-assisted Taylor approach was 90.9% in our study, which is comparable with that of other studies. Zhang et al [ 3 ] reported the success rate of an ELP and the regular LRP with the paramedian approach to the subarachnoid space. Successful dural puncture within two attempts of the ELP and the LRP had success rates of 97.8% and 82.8%, respectively [ 3 ].…”

“…We compared our success rate to those calculated in other studies to prove this hypothesis. Zhang et al [ 3 ] previously reported the success rate of an elevated lateral recumbent position (ELP) and the regular lateral recumbent position (LRP) with the paramedian approach to the subarachnoid space. Successful dural puncture within two attempts of the ELP and the LRP had success rates of 97.8% and 82.8%, respectively [ 3 ].…”

Successful dural puncture within two attempts of the ELP and the LRP had success rates of 97.8% and 82.8%, respectively [ 3 ]. Gupta et al [ 1 ] reported a failure rate of 15% with the conventional Taylor’s approach.…”

Dual- vs. Single-Plane Ultrasonic Scan-Assisted Positioning during Lumbar Spinal Puncture in Elderly Patients: A Randomized Controlled Trial

“…In fact, unlike puncture difficulties caused by thick dorsal subcutaneous tissue and unclear palpation of the spinous processes seen in obese patients, the main reasons for difficulties in elderly patients are the spondylosis-related narrowing of the interspinous space, disc compression, alterations in lumbar curvature, arthrogryposis-related narrowing of the laminae interval space, spondylosis-related pits at the spinous process, and incomplete calcification of the supraspinous ligaments [14,[18][19][20]. Hence, they present a challenge to spinal anesthesia in elderly patients.…”
