What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Effect of Different Types of Spinal Needles Used by First-year Anesthesia Residents on Procedural Success and Click Sensation: A Prospective, Observational Study | Clicking feeling: Considering that the click feeling due to dural puncture is taken, in which attempt (1, 2, and ≥3) the needle's guide was removed and the cerebrospinal fluid (CSF) arrival occurred Procedural success: Time until CSF is seen (<1.9sec, ≥2sec) | Spinal anesthesia procedure time | 
| The Effect of Different Types of Spinal Needles Used by First-year Anesthesia Residents on Procedural Success and Click Sensation: A Prospective, Observational Study | Procedural success: Time until CSF is seen (<1.9sec, ≥2sec) | Spinal anesthesia procedure time | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
