The use of ultrasound-guided (USG) technique for regional blocks is a well- established
method in regional anaesthesia with the added advantage of providing real-time images
of the plexus and nerves and surrounding structures, while significantly minimizing
complications. Even if the evidence is in favour of USG guided blocks suggesting that
the complications and frequency of complications are significantly lower, this review
article is all about few complications that have been published so far in the scientific
literature. The complications encountered following USG guided blocks has been categorised
into two broad headings: technical and non-technical (neurological, haematological,
miscellaneous) in this article.
