The dorsal penile nerve block (DPNB) is a common form of regional anaesthesia for circumcisions in children. The safety of this block has been questioned following several case reports of potentially serious complications. ⋯ We feel that the DPNB is a safe technique for circumcisions in infants and children.

Outpatient knee surgery has come to involve increasingly complex procedures. The authors present observational data from a nerve block algorithm designed for the care of outpatients undergoing knee surgery. The aim of this report is to demonstrate differences in pain and unplanned hospital admission associated with surgical complexity and nerve blocks used. ⋯ For complex knee surgery, the use of FSB was associated with less pain; the use of FNB or FSB (vs. no block) was associated with fewer hospital admissions.

When intrathecal and epidural opioids are administered, pruritus occurs as an unwanted and troublesome side effect. The reported incidence varies between 30% and 100%. The exact mechanisms of neuraxial opioid-induced pruritus remain unclear. ⋯ The treatment of intrathecal opioid-induced pruritus remains a challenge. Many pharmacological therapies, including antihistamines, 5-HT(3)-receptor antagonists, opiate-antagonists, propofol, nonsteroid antiinflammatory drugs, and droperidol, have been studied. In this review, we will summarize pathophysiological and pharmacological advances that will improve understanding and ultimately the management of this troublesome problem.

Case Reports[Orbital haemorrhage after medial canthus episclera (sub-Tenon's) anaesthesia].
Medial canthus episclera (sub-Tenon's) anaesthesia is a technique proposed as a suitable alternative to the more classical peribulbar block because of the greater reliability and more constancy in effectiveness. We report two cases of retrobulbar haematoma after sub-Tenon's anaesthesia, one with central retina artery compression needed anterior room punction. Sub-Tenon's anaesthesia, like peribulbar anaesthesia, can give also retrobulbar haemorrhage if the insertion of the needle is not limited to the anterior orbit.
