Videoscopic lung volume reduction surgery in an Australian public teaching hospital.

BACKGROUND: Lung volume reduction surgery (LVRS) has been a frequent literature topic in emphysema management recently. Opinions differ in regard to usefulness, efficacy, and selection criteria. AIMS: To present the results of our first 55 bilateral videoscopically resected group, with follow-up of up to three years, and to present some of the local methodology problems faced. METHODS: Thirty-nine men and 16 women, age range 40-77, had either upper lobe (42), mixed (two), or lower lobe (11) resections without buttressing (except for unilateral buttressing in several of the latter patients as part of an intrapatient comparison trial) according to their pattern of emphysema determined by CT and perfusion scanning. RESULTS: Thirty day mortality was 5.5%. Follow-up pulmonary function is available for 44 patients, and demonstrates a mean 51% improvement in FEV1, and significant improvement in FVC, PaO2, dyspnoea indices and walking distance, with a reduction in mean RV, TLC, PaCO2. FEV1 improvement is maintained above baseline at three years. Lower lobe surgery outcomes are at least as good as their upper lobe counterparts. CONCLUSIONS: Outcomes confirm improvements reported elsewhere, and suggest that videoscopic resection may provide worthwhile benefit to lower lobe patterns of emphysema. Other managment issues are discussed.

War games: using MRP (material requirements planning) audits to pinpoint problems and keep the competitive edge.

In today's world, it is a challenge just to stay in business, let alone remain competitive in a specific industry. We will show you how to pinpoint MRP II problems and attack them through self-assessment audits. You will discover the secrets of breaking down barriers between Master Schedulers, Material Planners, Production Control Planners, and the Manufacturing Line. Self-assessment audits are one way to take care of your planning functions before outside auditors take care of them for you.
