Comparative Study
Assessment of differential blockade by amitriptyline and its N-methyl derivative in different species by different routes.
Increasing the duration of local anesthesia and/or creating greater differential blockade (i.e., selective block of pain-transmitting nerve fibers) has been attempted by modifying currently available agents. Most drugs show a different profile depending on the model or species studied. This study was designed to investigate the differential nerve-blocking properties of amitriptyline and its quaternary ammonium derivative in rats and sheep. ⋯ Amitriptyline and N-methyl amitriptyline are potent Na+ channel blockers and show greater differential blockade in sheep than in rats. This differential blockade in sheep is greater than that produced by lidocaine or bupivacaine.

Alemanno's brachial plexus block ten years later: topographic study of the anesthetized areas.
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. ⋯ 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.

Case ReportsSurgical emphysema and Collet-Sicard syndrome after cryoblockade of the inferior alveolar nerve.
We present a case of Collet-Sicard syndrome (palsy of cranial nerves IX-XII) together with cervicofacial emphysema after cryoblockade to the mandibular division of the trigeminal nerve.
