Problem The objective of this study was to develop a useful and cost-effective olfactometer for routine clinical use. The apparatus was developed to provide a standardized threshold test for patients with olfactory disorders presenting in the ENT clinic. Methods A prospective study of olfactory thresholds in 48 healthy volunteers on 2 consecutive occasions, undergoing quantitative testing with an olfactometer. Further studies of 10 subjects performing 20 tests and 100 subjects performing a single test were also performed. An olfactometer was designed to deliver a semi-automated threshold test for an odor. It was designed as a device containing 8 logarithmic dilutions of an odor along with a control valve operated by software from a laptop computer. Common potential variables for olfactory threshold testing were considered including peak inspiratory flow rate and smoking status. The odors used for the studies were phenethyl alcohol (PEA) and eucalyptol. Subjects were asked to perform 2 tests within 1 month of each other and the mean threshold score for each test was calculated to help derive a test-retest score. Results Consistent olfactory thresholds for PEA were achieved with a mean concentration of 10–4. Test-retest reliability scores for the olfactometer were rx = 0.78 (95% CI 0.67 to 0.89). Common variables thought to affect olfactory testing including peak inspiratory flow rate and smoking were not found to have a significant effect on the threshold scores. Conclusion The Leicester Olfactometer provides a simple and cost-effective method of reliably assessing olfactory thresholds in the outpatient clinic. Significance Routine testing of olfaction can be provided with a sophisticated yet user friendly format that overcomes the expense of single use test kits and other commercially available kits. Support Departmental research funds used.

Background With its introduction for widespread clinical use, there has been an increase in reports of bronchospasm related to the administration of rapacuronium. As it is commonly used for rapid sequence intubation, it has been suggested that these effects may be related to an inadequate depth of anesthesia. The current study examines the airway effects of rapacuronium in tracheally intubated, anesthetized adults. Methods Endotracheal intubation was accomplished without the use of neuromuscular blocking agents. Dynamic compliance, tidal volume, peak inspiratory flow rate, peak expiratory flow rate, and peak inflating pressure were measured after administration of either rapacuronium (1.5 mg/kg) or cis-atracurium (0.2 mg/kg) to 20 adult patients (10 received rapacuronium and 10 received cis-atracurium) anesthetized with propofol-remifentanil. Results Statistically significant increases in peak inflating pressure (22 +/- 6 to 28 +/- 9 cm H2O, P = 0.0012) and decreases in dynamic compliance (108 +/- 43 to 77 +/- 41 ml/cm H2O, P = 0.0001), peak inspiratory flow rate (0.43 +/- 0.11 to 0.39 +/- 0.09 l/s, P = 0.0062), peak expiratory flow rate (0.67 +/- 0.10 to 0.59 +/- 0.09 l/s, P = 0.0015), and tidal volume (744 +/- 152 to 647 +/- 135 ml, P = 0.0293) occurred after administration of rapacuronium. No changes were seen after administration of cis-atracurium. Conclusion These data demonstrate that rapacuronium, but not cis-atracurium, has significant airway effects in intubated, mechanically ventilated adults.
