Anaesthesia and intensive care

The history of the development of humidifiers as a necessary accompaniment to mechanical ventilation is a fascinating one. In New Zealand in the 1960s, Fisher and Paykel, an established importer of a variety of household appliances, launched into the design and manufacture of humidifiers following the requirements envisaged at that time, for optimal use in the intensive care setting. This was a completely new venture for the company and led to the establishment of a separate Fisher and Paykel Health Care company for medical equipment manufacture, which has continued successfully to the present day.

Education and expertise in airway skills are central components of anaesthesia training, yet there is no formal monitoring of the airway experience or level of competence that registrars actually obtain. An audit was performed in two phases to prospectively document the airway management experience of registrars in one teaching hospital department. ⋯ The overall registrar group performed a mean of 18 laryngeal mask airways and 19 endotracheal intubations in the study month. Our findings indicate that the airway experience of anaesthesia trainees may be inadequate and therefore warrants further investigation.

Review Historical ArticleThe origins of the sniffing position and the Three Axes Alignment Theory for direct laryngoscopy.
The Three Axes Alignment Theory and the sniffing position for direct laryngoscopy are the anatomical basis for direct laryngoscopy. This position has been one of the hallmarks of airway management and yet its development is based on a small number of descriptive texts published between 1852 and 1944. This paper explores the origins of direct laryngoscopy and how the sniffing position came to be described. The seemingly incongruent techniques of the rigid bronchoscopist and direct laryngoscopist are discussed from an historical perspective.

Chlorhexidine is a widely used skin antisepsis preparation and is an ingredient in toothpaste and mouthwash. It is an especially effective antiseptic when combined with alcohol. Its antimicrobial effects persist because it is binds strongly to proteins in the skin and mucosa, making it an effective antiseptic ingredient for handwashing, skin preparation for surgery and the placement of intravascular access. ⋯ The incidence of contact dermatitis to chlorhexidine in atopic patients is approximately 2.5 to 5.4%. Acute hypersensitivity reactions to chlorhexidine are often not recognised and therefore may be underreported. This review discusses the pharmacology, microbiology, clinical applications and adverse effects of chlorhexidine.
