To evaluate the effectiveness of removing the stylet during spinal anesthesia for successful identification of the subarachnoid space.
Observed a case of spinal anesthesia for lower limb surgery.
Used a 25-G Quincke spinal needle with a midline approach.
Removed the stylet after piercing the ligamentum flavum to assess CSF flow.
Initially no CSF flow was detected with the stylet in place.
Free flow of CSF was observed upon slight advancement of the needle without the stylet.
Successful intrathecal local anesthetic injection was administered without complications post-surgery.
