In 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. ⋯ Our findings show that adrenaline only temporarily reduced digital blood flow. Perfusion of the digits persisted in every case.

Recent evidence suggests that the duration of the nociceptive block may be an important factor in determining the effect of the block on injury-induced hyperalgesia after block resolution. The authors examined whether a tonicaine nerve block lasting for 12 to 16 h could prevent late inflammatory hyperalgesia. ⋯ A prolonged nerve block (12-16 h) can prevent the development of long-lasting (3-5 days) inflammatory hyperalgesia. Prevention of late hyperalgesia can be provided not only by the preinjury block but also by the postinjury block administered when hyperalgesia is already well established.

Randomized Controlled Trial Comparative Study Clinical Trial[Analgesia using continuous axillary block after surgery of severe hand injuries: self-administration versus continuous injection].
To compare analgesia produced after surgery for severe hand trauma, by a continuous axillary block obtained either with a continuous injection (CA) or controlled by the patient (PCA). ⋯ Continuous axillary plexus blockade provides safe and effective postoperative analgesia. With the PCA technique results a lower quantity of bupivacaine is required and patient's satisfaction better.

Review[Indications and limits of nerve block techniques].
Repetitive nerve blocks as a monotherapeutic treatment are loosing importance in the therapy of chronic pain. Such invasive methods for pain reduction are just one strategy in the interdisciplinary and multimodal planning of pain therapy. ⋯ Furthermore, it is necessary for the physician to know the typical complications of the invasive treatment and to be able to manage them. It is recommended to document the pain course.

Comparative Study Clinical Trial[Continuous analgesia with a femoral catheter: plexus or femoral block?].
To evaluate the spread and quality of sensitive blockade produced by continuous and prolonged use of a femoral catheter inserted for postoperative analgesia. ⋯ In most patients, a local anaesthetic administered continuously via a femoral catheter produces a blockade limited to the femoral nerve. These data do not substantiate the conclusions by those who consider they are producing a continuous "3 in 1" block with this technique. However, it is obviously not essential to produce a sensitive blockade of the three main nerves of the lumbar plexus to obtain an effective analgesia after knee surgery.
