Construction of a novel port wine stain phantom and measurement of colour by digital imaging and reflectance spectrophotometry.

A novel skin phantom is described that is constructed with quantifiable amounts of skin pigments, as well as a light scattering medium in the form of barium sulphate suspension. The two predominant skin pigments (melanin and haemoglobin) are varied in controlled amounts within the phantoms to simulate skin colour in different situations. The phantoms were devised in order to simulate the changes in skin colour particularly after laser treatment of port wine stains, where superficial cutaneous vascularity is reduced.

Carotid endarterectomy. A survey of UK anaesthetic practice.

We conducted a postal questionnaire survey of the members of the Vascular Anasthesia Society of Great Britain and Ireland, asking questions about the provision of anasthesia for carotid endartectomy. Of 215 respondents, 187 were currently providing anasthesia for carotid endarterectomy. The majority of respondents (69%) always use general anasthesia for this operation but 99/215 (46%) had some experience of regional anasthesia for carotid endartectomy.

Improving patients' postoperative sleep: a randomized control study comparing subcutaneous with intravenous patient-controlled analgesia.

One hundred female patients undergoing major reconstructive plastic or gynaecological surgery were randomized to either receive subcutaneous patient-controlled analgesia (PCA) (bolus dose 2.5 mg diamorphine in 1 ml with a 20-minute lockout) or intravenous PCA (bolus dose 0.5 mg diamorphine in 1 ml with a 5-minute lockout).
