NOTIS: an operating theatre information system.

Solutions to straightforward resource management problems need not always involve the use of complex, specialised and expensive software solutions. Commercially available 'off the shelf' packages have increased in flexibility and ease of use, and are usually an order of magnitude cheaper than their custom designed counterparts. In response to a request for a low cost database suitable to be used on a stand-alone microcomputer system, the widely available integrated software package Smart was used. The program specification required quantification and analysis of the workload in a medium sized operating theatre suite (at 6,000 cases/year) to be undertaken. In addition to providing Database, Spreadsheet and Wordprocessor modules, each with rapid and easy exchange of data from one module to another, Smart incorporates its own programming language. This may be used to build up complex series of instructions for data manipulation, to generate menus and create a naive user front end to the finished program. Although an adequate knowledge of database construction and basic programming are necessary, professional programming skills are not required. NOTIS, the Newham Operating Theatre Information System, is a menu driven program designed to be used by clerical staff, and accepting patient data derived from within the operating theatre. At the end of each month a set of predetermined reports are produced. These reports are designed to provide information on the workload, case type and medical personnel involvement applicable to theatre managers, anaesthetists and surgical staff.

The response of canine intracranial pressure to systemic hypotension induced with nitroglycerine.

Changes in intracranial pressure were studied in 18 greyhounds in relation to decreases in systemic arterial pressure produced by nitroglycerine. At normal values of i.c.p. (less than 12 mm Hg) GTN produced an increase in i.c.p. of 3.1 (+/- 0.6) mm Hg (mean +/- SEM). Under conditions of increased i.c.p. (12 + mm Hg) small decreases in mean arterial pressure (m.a.p.) (less than 25% control) were associated with an increase of 4.7 (+/- 0.5) mm Hg, whereas larger decreases in m.a.p. (greater than 25% control) were associated with a decrease of 3.2 (+/- 0.9) mm Hg in i.c.p. In 11 of 19 observations in which a decrease in intracranial pressure had occurred in association with systemic hypotension there was a rebound increase in i.c.p. as m.a.p. was restored. It is suggested that i.c.p. be decreased before this drug is used to produce hypotension during neurosurgery.
