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.

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).

Randomized Controlled Trial Comparative Study Clinical TrialPenile block timing for postoperative analgesia of hypospadias repair in children.
It has been well established that a dorsal penile nerve block immediately after surgery decreases postoperative pain in children undergoing hypospadias repair. However, to our knowledge the efficacy of a penile block immediately before versus immediately after surgery for postoperative pain control has not been previously studied in such children. ⋯ Two penile blocks performed at the beginning and conclusion of hypospadias repair, respectively, provide better postoperative pain control than 1 penile block done before or after surgery (p < 0.05). These patients require less analgesic than those who receive a penile block only before or only after surgery.
