The role of innominate artery ligation in the management of massive haemorrhage from trachea-innominate artery fistula.

摘要

We read the comments by Dr Gomez-Rios with interest. As there was limited knowledge about dose, volume and continuous catheter technique, our aim was look for differences between the groups. In 2009, during the design phase of our study, there had been no studies published on either a continuous technique or ropivacaine concentrations. Our study followed a retrospective study of continuous catheter transversus abdominis plane block, using 8 ml/hour of 0.2% ropivacaine, which found no untoward effects1. We do understand the concern about local anaesthetic toxicity and have just concluded a study (not yet published) estimating ropivacaine concentrations during a continuous catheter technique.
