EditorAs a proponent of ultrasound-guided regional anaesthesia, I enjoyed reading the excellent case series by Karmakar and colleagues.1 However, I have reservations about a number of the conclusions drawn in the accompanying editorial by Hopkins.2 I agree that the recent regional anaesthesia ultrasound literature has many studies that lack equipoise. However, this fact surely reinforces our responsibility to strive for the best quality ultrasound studies in order to properly answer the question of whether ultrasound techniques really do have significant advantages. This is because there are many existing and very successful users of other regional anaesthesia techniques that correctly demand the highest quality evidence before committing to the significant expense and inconvenience of training with new technology. Although I would agree with Professor Hopkins that almost all radiologists would support the use of ultrasound for certain interventional techniques, this opinion has been developed through studies that exist in the radiology
