Elderly cataract patients frequently have comorbid multisystem disease. Local or regional anesthesia is provided to reduce complications of retrobulbar infiltration. Performing painless eye blocks without sedation is probably the safest route.

To determine the effect of bilateral hypoglossal and and glossopharyngeal nerve block on epiglottic and soft palate position and tracheal and pharyngeal pressures in exercising horses. ⋯ Loss of contact of the epiglottis with the soft palate did not affect soft palate position, suggesting that when the soft palate is normal, the epiglottis does not function as a support, holding the soft palate in a ventral position. Therefore, epiglottic dysfunction is not solely responsible for intermittent dorsal displacement of the soft palate in horses, and neuromuscular dysfunction involving the hyoepiglotticus muscle, geniohyoideus muscle, or the hypoglossal nerve may cause epiglottic retroflexion in horses.

Randomized Controlled Trial Clinical Trial
Dose-range effects of clonidine added to lidocaine for brachial plexus block.
Although addition of clonidine to local anesthetics can prolong pain relief after peripheral nerve block, a dose-range effect has not been determined. ⋯ This study suggests that a small dose of clonidine enhances the quality of the peripheral blocks from lidocaine and limits the classical alpha2-agonist side effects to sedation.
