The authors report a case of cardiac arrest following interscalene brachial plexus block in the sitting position for shoulder arthroscopy. The cardiac arrest occurred 45 minutes after interscalene brachial plexus block. It seems that it resulted from the activation of Bezold-Jarisch's reflex and a related vasovagal syncope.

[Clinical experiences and dosage pattern in subcutaneous single-injection digital block technique].
100 patients with injuries to their fingers were treated using the subcutaneous digital block as described by Low et al.. Different dosages ranging from 2 to 3 millilitres of a local anesthetic were required to obtain appropriate anesthesia according to the location of injury. 108 finger injuries were treated, 18 thumb injuries, 90 finger injuries. The anesthetic was administered using a 0.55 x 25 mm needle and injected strictly subcutaneously into the flexor crease at the base of the finger or thumb. ⋯ Additionally, we performed a deep local nerve block (Oberst), if the patient still felt discomfort or pain. The severity or type of injury did not play a role according to our findings. The subcutaneous finger block as described by Low et al., therefore, is the method of choice treating injuries to the fingers and to the palmar aspect of the thumb, since it offers a decrease in the amount of anesthetic required and increases patient comfort.

To study the efficacy and complications of a parascalene block over a period of 10 years of experience. ⋯ The parascalene block is a simple, safe, and effective technique. The probability of serious complications is lower than with most known supraclavicular techniques, mainly because the puncture is perpendicular to the horizontal plane. A neurostimulator or aponeurotic click technique is used and the nerve trunks can be found between 1,5 and 2 cm deep when the plexus is located in reference to the transverse processes.
