Long-term Effects of Radial Artery Cannulation on Vessel Diameter, Blood Flow and Fine Motor Skills

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.
