Conditions

Health Condition 1: null- ASA I-II patients with in the age group of 18-60 years scheduled for routine/elective surgery, requiring radial artery cannulation

Interventions

Intervention1: RADIOLOGICALLY OPTIMIZED WRIST ANGLE: palpation of the radial artery was not allowed/performed. In order to optimize the wrist, we performed ultrasonographic examinations of the wrist u
