AIM: The study analyzes the extension of anesthesia induced by Alemanno's brachial plexus block technique on the various areas of competence of the different nerves. METHODS: The study was conducted on 58 patients in ASA classes 1 and 2 scheduled to receive shoulder arthroscopy. At the end of the operation, about 2 hours after induction of anesthesia, extension of anesthesia was evaluated by the pin-prick test. RESULTS: Anesthesia was achieved in 100% of cases for the circumflexus, musculocutaneous and radial nerves; the median nerve escaped in 7% of cases, the medial cutaneous nerve of forearm in 20%, the ulnar nerve in 27.5%, the medial cutaneous nerve of arm and intercostobrachial nerves in 46%; no major complications were associated with the technique. CONCLUSION: Alemanno's technique is recommended for operations on the shoulder and humerus, whereas more peripheral techniques may be preferable for interventions on the forearm and hand.
BACKGROUND: Aim of the present study is to review the four different methods of brachial plexus block, with supraclavicular approach, which have reached the higher approval or given less side effects. METHODS: The Author reviewed the following techniques: Kulenkampff's (1911), Winnie's (1970), Brown's (1988) and Alemanno's (1992). CONCLUSIONS: The four methods that were presented in the last century differ not for the results, which are more or less the same, but for the possible side effects, which result to be less with the latest techniques.
The paper reports the results of a new brachial plexus blockade technique using a supraclavicular route which was carried out in 74 patients. From the analysis of results it can be seen that the technique is comparable to that of Moore and Winnie in terms of the success of the blockade. However, this technique appears to be safer in relation to complications such as pneumothorax and subarachnoid injection.
In order to avoid complications such as pneumothorax or subarachnoid injection, the paper proposes a new approach to brachial plexus using a supraclavear route based on the pulse of the subclavian artery and 7th cervical vertebra. Complications are unlikely using this route.
Having described the therapeutic protocol to be followed in cases of cerebral edema, starting with aspecific measures (hyperventilation in a position of 30 degrees, etc.) for slight cases and progressing to specific therapy (osmotherapy, barbiturates) for more severe cases, the paper focuses on osmotherapy and illustrates the theoretical principles on which it is based and its use in clinical practice.
