•Adult patients scheduled to undergo elective surgery under general anesthesia at our institution, for whom radial arterial line placement is planned for invasive blood pressure monitoring during surgery
•Patients in whom preoperative ultrasonographic assessment of the radial artery is feasible
•Patients with a BMI of >16 kg/m2 and <35 kg/m2

•Patients judged unable to provide sufficient cooperation for preoperative ultrasonographic examination due to impaired consciousness, cognitive decline, delirium, or severe agitation
•Dialysis patients with an arteriovenous fistula in the forearm
•Patients with a history of ipsilateral radial artery puncture within the preceding month
•Patients judged to have factors predictive of difficult puncture based on preoperative ultrasonographic assessment, defined as any of the following:
•Depth from the skin to the anterior wall of the radial artery =>4 mm
•Radial artery internal diameter <=2.2 mm
•Presence of bifurcation, tortuosity, or calcification of the radial artery
•Patients who did not provide informed consent to participate in the study
•Patients judged ineligible for any other reason by the principal investigator
