Aqueous Humor Circulation in the Era of Minimally Invasive Surgery for Glaucoma.

Glaucoma surgery with implantation of aqueous humor draining microstents may compromise long-term corneal health by disrupting aqueous humor circulation. The effect of stent numbers on this circulation was interrogated to determine the number of stents associated with minimal circulation disruption. An in vitro anterior eye model perfusion system was constructed with multiple exit ports.

Anaesthesia for microlaryngeal and laser laryngeal surgery: impact of subglottic jet ventilation.

Objective: Over the past 20 years, jet ventilation techniques have been developed to enable safe and controlled microlaryngoscopy and the accurate treatment of laryngeal pathology. This study examined how advances in jet ventilation tube design have facilitated safe endolaryngeal surgery.

Study Design: The study documented the development and use of the Jockjet subglottic jet ventilation tube system at the Prince of Wales Hospital, Sydney.

The venous flow augmentation pump: a solution to venous congestion.

Venous congestion is a well-recognized cause of failure of survival of replanted digits. When re-exploration of a venous congested digit is not possible, an alternate solution is presented. A description of the venous flow augmentation pump is provided, along with a preliminary case report of its successful use.
