Ultrasound reduces the minimum effective local anaesthetic volume compared with peripheral nerve stimulation for interscalene block.
BACKGROUND Previous studies have demonstrated that lower local anaesthetic (LA) volumes can be used for ultrasound (US)-guided interscalene brachial plexus block (ISB). However, no study has examined whether US can reduce the volume required when compared with nerve stimulation (NS) for ISB. Our aim was to do this by comparing the minimum effective analgesic volumes (MEAVs). METHODS After eth...
متن کاملMinimum effective volume of 0.5% bupivacaine with epinephrine in ultrasound-guided interscalene brachial plexus block.
BACKGROUND The use of ultrasound (US) in regional anaesthesia enables a reduction in the local anaesthetic volume. The present study aimed to determine the minimum effective volume (MEV(90)) of 0.5% bupivacaine with epinephrine for interscalene brachial plexus block (ISBPB). METHODS The volume of the anaesthetic was determined using a step-up/step-down method and was based on the outcome of t...
متن کاملHyaluronidase reduces local anaesthetic volumes for sub-Tenon's anaesthesia.
BACKGROUND Volumes of local anaesthetics for sub-Tenon's anaesthesia vary. Lower volumes produce less akinesia, whereas higher volumes increase chemosis and intra-ocular pressures. Hyaluronidase is often added to local anaesthetics to improve akinesia without increasing the volume of the injection, but this is controversial. This randomized, sequential allocation study examines the addition of ...
متن کاملEstimation of the minimum effective volume of 0.5% bupivacaine for ultrasound-guided axillary brachial plexus block.
BACKGROUND AND OBJECTIVE The use of ultrasound for needle correct placement and local anesthetic spread monitoring helped to reduce the volume of local anesthetic required for peripheral nerve blocks. There are few studies of the minimum effective volume of local anesthetic for axillary brachial plexus block. The aim of this study was to determine the minimum effective volume (VE90) of 0.5% bup...
متن کاملUltrasound assessment of cranial spread during caudal blockade in children: the effect of different volumes of local anaesthetics.
BACKGROUND Despite the large amount of literature on caudal anaesthesia in children, the issue of volume of local anaesthetics and cranial spread is still not settled. Thus, the aim of the present prospective randomized study was to evaluate the cranial spread of caudally administered local anaesthetics in children by means of real-time ultrasound, with a special focus on the effects of using d...
