Ergonomic aspects of equipment.

Mechanical patient-lifting devices have been available for hospital use for at least the past 100 yr. Mobile hoists have been available since the 1950s and the most common U.K. hospital mobile hoist, the Mecanaids' Ambulift, has been available since 1966. Recent investigations have confirmed that these devices are not being used to any significant extent to ease most of the patient-lifting problems in hospital wards. Attention to four variables, the patient, the attendant, the task and the environment, is essential in determining the right systematic approach to equipment design and selection.

Investigation of Possum users in Scotland.

New users in Scotland of Possum PSU3 environmental control equipment were investigated over a 2-year period. At the conclusion of the study, of 48 disabled people, some 9 months after installation, 29 (60%) were still using the equipment, seven (15%) still had the equipment but were not using it, seven (15%) had had the equipment removed or cancelled at their request, and five (10%) had died. Of the 29 users eight (28%) were having specific operational difficulties. Analysis of a series of factors which could have influenced the outcome of the study did not reveal any one statistically significant factor affecting the success or failure of the use of the equipment for the whole sample. Individual case studies did reveal some problems which should be attended to, and which are relevant to occupational therapists.

Trazodone: a simple, clean extraction and rapid quantification by high pressure liquid chromatography.

We have developed an HPLC technique which is precise, rapid and reliable. Sample preparation involves simple alkaline extraction into an organic solvent mixture. Trazodone elutes at 3.2 min in this reverse phase system. There is no requirement for elevated column temperature. The method is linear to 3000 ng/ml. The availability of a technique which is transferrable to the clinical laboratory may help to define the proper role of therapeutic monitoring of trazodone.

Quantitation of tobramycin by solid-phase immunofluorescence.

Tobramycin usage, as for most aminoglycoside antibiotic usage, may require careful monitoring to avoid irreversible toxicity. Several methods for tobramycin quantitation are available. The purpose of this study was to evaluate the performance of solid-phase immunofluorescence as an alternative. Tobramycin was quantitated in the sera of 81 patients by radioimmunoassay and solid-phase immunofluorescence. No statistically significant or medically important difference was demonstrated (bias, 0.006 micrograms/ml, t = 0.09, s = 1.02, r = 0.97). Within-run and run-to-run precision for the two methods were comparable. Interference by gentamicin could not be demonstrated. Solid-phase immunofluorescence may be an acceptable alternative method for tobramycin quantitation in some laboratories.
