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.

Clinical TrialSuperficial and deep cervical plexus block for carotid artery surgery: a prospective study of 1000 blocks.
Cervical plexus blocks are performed for carotid surgery to allow neurological assessment of the awake patient. The aim of this study was to establish the frequency of success, complications, and patient acceptance of the technique. ⋯ We conclude that superficial and deep cervical plexus block has a high success rate, low complication rate, and high patient acceptance rate. Caution should, however, be exercised to ensure a low intravascular injection rate which is of most concern with this technique, because blood was aspirated in 30% of patients during performance of the block.

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.

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.
