Interpreting meta-analysis of ultrasound-guided vs palpation methods for radial artery cannulation may not fully capture differences in technique optimization

The recent updated systematic review and meta-analysis by Bhattacharjee et al. [1] outlining the comparison of ultrasound-guided versus digital palpation techniques for radial artery cannulation discusses a number of methods that have been used to optimize ultrasound visualization of the radial artery prior to needle puncture. In particular, they mention both short-axis out-of-plane and long-axis in-plane techniques, as well as dynamic needle tip positioning. [2] However, there are other techniques which have also been utilized including distal radial artery compression as outlined by Shao et al.
