Other potential uses of serratus anterior plane block

Blanco et al.'s description of a new serratus anterior plane block could indeed prove useful in managing pain after breast surgery, and this block appears to be more easily performed than other techniques mentioned in his paper 1. I would invite the authors to comment on whether they consider serratus anterior plane block suitable for providing analgesia for patients with thoracic trauma, and if they were aware of any trauma cases in which the block was performed and their outcome. Also, could this technique be used to provide continuous analgesia by siting the catheter tip superficial to the serratus anterior muscle? Finally, do the authors consider this block to be suitable for patients with deranged coagulation or who are taking anticoagulants?
