The concept of a closed peri-neurovascular space surrounding the cervicobrachial plexus, introduced by A. Winnie, allows the blockade of the cervical and brachial plexuses by means of a single puncture technique. The single puncture has positive advantages: 1. ⋯ A new indication seems to be the implantation of a cardiac pacemaker. Complications often quoted in literature are Horner syndrome-a minor complication-and blockade of the ascending branches of the recurrent laryngeal nerve and of the phrenic nerve.

Bilateral superior laryngeal nerve block was combined with topical application of local anaesthetic 140 times in 135 patients to anaesthetize the upper airway and facilitate tracheal intubation, laryngeal instrumentation, or to diminish the response to the endotracheal tube, in a patient already intubated. The technique was successful in 92% of attempts.
