    Notes: We placed patients with invasive epithelial ovarian cancer into four distinct prognostic groups: ‘low’, ‘moderate’, ‘high’ and ‘extreme’ risk. The ‘moderate-risk’ group contained all residual negative, stage I and II patients with two exceptions: stage Ia or b, grade 1 cancers and grade 3 cancers. They were treated with primary surgery, usually including bilateral salpingo-oophorectomy, hysterectomy and omentectomy. Chemotherapy was then given (cisplatin at 100 mg m−2 every 2 weeks for three cycles) followed by pelvi-abdominal irradiation (2250 cGy in 10 fractions to the pelvis and 2250 cGy in 22 fractions to the whole abdomen including pelvis). An early cohort with ascites or positive washings instead received six cycles of cisplatin and cyclophosphamide at 75 mg m−2 and 600 mg m−2 every 4 weeks with the same pelvi-abdominal irradiation sandwiched between cycles 3 and 4. One-hundred and nine patients were treated between November 1983 and December 1989. Median follow-up was 4.7 years (range 0.7–9 years). The 5-year actuarial overall and failure-free survivals were 81% and 76%, respectively. Chronic toxicity, although usually minor, included 15% with peripheral neuropathy or ototoxicity and 23% with chronic abdominal complaints. Our combined-modality results are similar to those obtained by other centers utilizing either pelvi-abdominal irradiation alone or cisplatin-based chemotherapy alone.

    Notes: Summary The use of end-tidal carbon dioxide monitoring to confirm the correct placement of a tracheal tube immediately after intubation is mandatory in the operating theatre. Tracheal intubation in critically ill patients can be challenging. Quick and accurate confirmation of tracheal tube placement is essential to minimise complications. This survey explored the use of end-tidal carbon dioxide monitoring to confirm tracheal tube placement in intensive care units in the UK. Questionnaires were sent to either the lead clinician or clinical director of randomly selected general adult intensive care units. One hundred and twenty-seven replies were received from the 215 questionnaires sent (response rate 59%). Twenty per cent of the units did not have an end-tidal carbon dioxide monitor, 20% had one end-tidal carbon dioxide monitor per bed and 60% had one end-tidal carbon dioxide monitor between several beds. Only 50% of the units having an end-tidal carbon dioxide monitor use it to confirm correct tracheal tube placement. Of these 50%, only about a third use it for every intubation. Seventy-two per cent of respondents felt that end-tidal carbon dioxide is well suited to confirm correct placement of tracheal tube in critically ill patients, but 50% did not think that confirmation using end-tidal carbon dioxide should be mandatory for intubations outside the operating theatre. Half of the units not having end-tidal a carbon dioxide monitor cited lack of resources as a reason. In summary, although four in every five intensive care units surveyed have end-tidal carbon dioxide monitors, only a small proportion use them to confirm correct placement of tracheal tube after intubation.

    Notes: Pre-operative optimisation of high-risk patients undergoing major elective surgery has been shown to decrease peri-operative morbidity and mortality. It is also cost effective because of the resulting decrease in postoperative complications. A questionnaire was sent to 170 intensive care and high dependency units in Britain in order to quantify the number of units practising pre-operative optimisation. There was a 91% response rate. Of the respondents familiar with the evidence advocating pre-operative optimisation, 91% believe pre-operative optimisation improves outcome but only 62% admit patients for such preparation. Moreover, only eight units (6%) admit more than 25% of eligible patients. The reasons given for not admitting such patients pre-operatively are a lack of manpower, beds or both. This survey demonstrates the need for greater investment of resources into intensive care and high dependency units, so that clinicians can deliver high-quality evidence-based healthcare in accordance with the principles of clinical governance.

    Notes: Abstract Objective: The cause of the metabolic disturbances in sepsis remains uncertain, but there is increasing evidence suggesting that haemodynamic changes are not solely responsible. We addressed the question of whether endotoxin has a significant effect on cellular oxygen metabolism, independent of confounding haemodynamic defects. Design: Prospective, controlled experimental study. Setting: University Laboratory. Model: Human hepatocyte cell line. Methods: The oxygen consumption rate (OCR) was calculated from the fall in oxygen tension in a sealed cuvette containing Hep G2 cells in suspension. The oxygen tension was measured by porphyrin phosphorescence half-life analysis. Resting OCR was measured in control cells and after 1, 6 and 24 h of endotoxin exposure. In a second series of experiments, resting and maximal OCR was measured after 6 and 24 h of endotoxin exposure and in control cells using the addition of a mitochondrial uncoupler (FCCP); this uncouples the respiratory chain from ATP synthesis, thereby removing negative feedback and allowing the respiratory chain to work at maximal rate. Results: Endotoxin caused a rise in resting OCR at 1 h which was significant by 6 h but had returned to control values by 24 h. Maximal OCR also increased at 6 h, however exposure to endotoxin for 24 h significantly reduced maximal OCR compared to the control cells. Conclusions: Endotoxin has complex effects on cellular energy metabolism causing an initial rise in the oxygen consumption rate and a significant limitation in oxygen consumption capacity at 24 h. These complex effects would be in keeping with the varied responses seen in patients.
