Retrobulbar anaesthesia for adjustable strabismus surgery in adults: a prospective observational study.

Objective: To characterize the ocular response to retrobulbar anaesthesia and to evaluate the efficacy of retrobulbar anaesthesia for adjustable strabismus surgery in adults.

Design: Prospective observational study.

Participants: Adult patients undergoing adjustable strabismus surgery under retrobulbar anaesthesia.

Prevention and treatment of virulent bacterial biofilms with an enzymatic nitric oxide-releasing dressing.

The use of percutaneous medical devices often results in nosocomial infections. Attachment of microorganisms to the surfaces of these medical devices triggers biofilm formation, which presents significant complications to the health of a patient and may lead to septicemia, thromboembolism, or endocarditis if not correctly treated. Although several antimicrobials are commonly used for prevention of biofilm formation, they have limited efficacy against formed biofilms.
