In a well-defined fast-track setup for total hip and knee arthroplasty, with a multimodal analgesic regimen consisting of intra-operative local anaesthetic infiltration and oral celecoxib, gabapentin and paracetamol for 6 days postoperatively, we conducted a prospective, consecutive, observational study. The purpose was to describe the prevalence and intensity of subacute postoperative pain and opioid related side effects, use of analgesics and functional ability 1-10 and 30 days postoperatively. ⋯ However, after total knee arthroplasty 52% patients reported moderate pain (VAS 30-59 mm), and 16% severe pain (VAS > or = 60 mm) when walking 1 month after surgery with a concomitant increase in the use of strong opioids. These results emphasise the need for improvement in analgesia after discharge following total knee arthroplasty, to facilitate rehabilitation.

We studied the LMA Supreme in 100 elective, anaesthetised, healthy patients assessing: ease of use, airway quality, anatomical and functional positioning, airway leak and complications. Insertion was successful on first, second or third attempt in 90, nine and one patient respectively. Thirty manipulations were required in 22 patients to achieve a clear airway. ⋯ Other complications and patient side-effects were mild and few. The LMA Supreme is easily and rapidly inserted, providing a reliable airway and good airway seal. Further studies are indicated to assess safety and performance compared to other supraglottic airway devices.

We previously defined surgical list 'efficiency' as: maximising theatre utilisation, minimising over-running, and minimising cancellations. 'Efficiency' maximises output for input; 'productivity' emphasises total output. We define six criteria that any measure of productivity (better termed 'quantitative performance') needs to satisfy. We then present a theoretical analysis that fulfils these by incorporating: 'speed' of surgery (with reference to average speeds), 'patient contact' (synonymous with minimising gaps between cases), and 'efficiency' (as previously defined). 'Speed' and 'patient contact' together constitute a 'productive potential'. Our formula satisfies the pre-set criteria and yields plausible results in both hypothetical and real data sets, To be productive in these quantitative terms, teams in any specialty need to achieve minimum quality standards defined by their sub-specialty; to plan their lists to utilise the time available with no cancellations or over-runs and to work at least as fast as average with minimal gaps between cases. 'Productive potential' combined with 'efficiency' yielding 'actual productivity' in our theoretical analysis more completely describes quantitative surgical list performance than any other single measure.
