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 Comparative Study Clinical Trial
Comparison of transthecal and subcutaneous single-injection digital block techniques in cadaver hands.
A controlled, randomized single-blinded study was performed on the thumbs and little fingers of 20 cadaver hands. The digits were randomly divided into 2 groups. In the transthecal group, 2 mL of 0.5% methylene blue was injected into the tendon sheath at the A1 pulley. ⋯ In the transthecal group, intra-articular staining of the metacarpophalangeal joint was noted in 3 little fingers and 1 thumb. This complication did not occur in the subcutaneous group. This difference was significant (p < .05).

Case ReportsContinuous parasacral sciatic nerve block: two case reports.
This study investigated the use of a continuous parasacral sciatic nerve block for anesthesia and postoperative analgesia for lower extremity surgery. ⋯ We conclude that continuous parasacral sciatic nerve block can provide anesthesia and long-term analgesia for operative procedures of the foot and leg.

Randomized Controlled Trial Comparative Study Clinical Trial
Regional anaesthesia for circumcision. Subcutaneous ring block of the penis and subpubic penile block compared.
In this prospective study techniques for the subcutaneous ring block of the penis and subpubic block of the penis for analgesia after circumcision were compared. Forty-five boys having circumcision as day-case patients were allocated randomly to have either a subcutaneous ring block or a subpubic penile block. The blocks were inserted after induction of anaesthesia but before surgery. ⋯ Four of the 24 boys who had subpubic penile blocks and nine of the 16 boys who had subcutaneous ring blocks were given morphine for post-operative pain (P = 0.015). The surgeons complained about oedematous tissues in three patients, all of whom had had subcutaneous ring blocks. The subpubic penile block provided significantly better analgesia than the subcutaneous ring block of the penis.
