简要总结
Arterial cannulation is required in various surgeries and intensive care units for the beat to beat arterial pressure monitoring and arterial blood gas analysis. The arterial cannulation is routinely done using the palpation method where the artery is palpated and the arterial cannula is inserted. However, this method has some limitations such as less first-pass success rate, requiring a longer clinical experience and puncture site hematoma due to a lack of real-time guidance. Direct Waveform Assistance (DiWA) is a newer technique where arterial cannulation is done under direct arterial waveform guidance. Hence, this is planned to compare arterial cannulation palpation method with or without Direct Waveform Assistance (DiWA) in patient who required radial artery cannulation under general
anaesthesia. The study will enroll 206 patients who will require arterial cannulation under general anaesthesia and required surgical procedure.
