The present study aims to investigate hemodynamic changes in radial and ulnar artery blood flow following radial artery cannulation performed in elective surgical cases under operating room conditions using Doppler ultrasonography. Additionally, it aims to evaluate the long-term impact of this procedure on vascular flow parameters and fine motor function.

This prospective self controlled study included 50 patients aged 18-80 years with an ASA physical status of 1-3 who required arterial cannulation for planned surgical procedures in the cardiovascular surgery operating rooms of Pamukkale University Faculty of Medicine. Before the procedure, radial and ulnar artery Doppler parameters (peak systolic velocity, end-diastolic velocity, resistance index, pulsatility index, and mean volume flow) were measured for all patients, along with Purdue Pegboard scores for fine motor skill assessment. Post-cannulation Doppler parameters were evaluated at seven different time points over three months, while fine motor skill scores were measured twice more during follow-up.

Inclusion Criteria:

indication for radial artery cannulation

Exclusion Criteria:

emergency surgery inadequate collateral blood flow

patients undergoing surgical intervention at Pamukkale University Faculty of Medicine, Department of Cardiovascular Surgery, between June and September 2016. Patients aged 18 to 80 years, scheduled for elective surgery, and with an indication for radial artery cannulation were included in the study.
