AbstractIn the early part of the century, when adrenaline first became widely available, it was used in an uncontrolled manner and cases of ischaemic necrosis led to it falling into disfavour for hand surgery. Local anaesthesia with adrenaline is currently widely used for palmar and dorsal hand surgery but there remains a very deeply ingrained resistance to its use for digital anaesthesia. It is widely thought that it will cause irreversible digital artery vasospasm. This prospective study reports the effect of 2% lignocaine with 1:80,000 adrenaline digital blocks on various parameters of digital arterial blood flow in 100 consecutive patients. Our findings show that adrenaline only temporarily reduced digital blood flow. Perfusion of the digits persisted in every case.
