Interventions

Medical Device : This study compares two types of radial artery catheters. The experimental group uses the Arrow Radial Artery Catheterization Set (RA-04020, RA-04122, Teleflex®), which includes a gui

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Adults aged 19 years or older Patients who require prolonged arterial pressure monitoring after general anesthesia and undergo arterial catheterization Individuals who have agreed to participate in the clinical trial and signed the informed consent form

Exclusion criteria

Exclusion criteria: Children under 19 years of age Patients in whom cannulation of both radial arteries is contraindicated (e.g., presence of AVF, history of injury, or failure to pass Allen’s test) Patients with peripheral arterial disease or moderate to severe valvular heart disease Individuals deemed by the investigator to be unsuitable for participation in the clinical trial
