Regional Anesthesia Morbidity
Conditions
Brief summary
Confirming the L4-L5 or L3-L4 vertebrae level with ultrasound in real time for adults who scheduled elective surgery under spinal anesthesia, and introduce the spinal needle into the subarachnoid space. The ultrasound probe continues to track needle tips in real time by sliding/tilting with short axis view. Check that the spinal needle reaches subarachnoid space, and that CSF is released through the needle hub, and administer the drug. In this process, it is recorded by observing the success of the procedure, the time taken for each step, the number of needle position changes, NRS pain score of the subject, satisfaction with anesthesia, and its side effects.
Interventions
The neuraxial US scan will be performed with the patient in the lateral position with the hip and knees flexed using full aseptic technique. The spinal needle will be inserted in real-time under direct ultrasound guidance using dynamic needle tip positioning to administer the spinal anesthetic.
