Comparative in-vitro Study of the Trachospray, a New Device for Topical Anaesthesia of the Upper Airway.

Background: Obtaining complete topical anaesthesia of the airway remains a clinical challenge. Particle size is one of the most important variables for the dose deposited and the distribution of aerosols in the airways. The mass median aerodynamic diameter of the particles should be in the range of 5-20 µm.

Use of telehealth for patients referred to a retrieval service: timing, destination, mode of transport, escort level and patient care.

We examined the utility of telehealth in assisting the decision-making processes of aeromedical coordinators, with particular focus on the timing, destination, mode of transport and escort level. Medical coordinators from the Northern Operations site of the Queensland emergency retrieval service were asked to complete a survey form about the changes that telehealth made to their retrieval decision-making process. Information was collected in six areas: diagnosis, severity, priority, crew, mode of transport and destination.

Curative effect of topical treatment of digital dermatitis with a gel containing activated copper and zinc chelate.

The efficacy of two topical treatments for painful ulcerative stage (M2) of bovine digital dermatitis (BDD) lesions was compared in a clinical trial conducted on five dairy farms in 2009 to 2010. The first treatment was a water-based gel with active components copper and zinc (Intra Hoof-fit gel [IHF]) and the second treatment was a topical chlortetracycline spray (CTC spray). The experimental unit for this study was the hindleg with the presence of a BDD lesion.
