Due to the growing importance of quality assurance and cost containment in healthcare, eliciting patients' preferences for post-operative outcomes may be a more economical and reliable method of assessing quality. Three hundred and fifty-five day surgery patients completed a pre-operative written questionnaire to identify patients' preferences for avoiding 10 particular post-operative symptoms: pain, nausea, vomiting, disorientation, shivering, sore throat, drowsiness, gagging on the tracheal tube, thirst and a normal outcome. The two scoring methods used to evaluate preferences were priority ranking and relative value scores. The effects of age, gender, previous health status, type of surgery and previous experience of anaesthesia on patients' preferences were also examined. Avoiding post-operative pain, gagging on the tracheal tube and nausea and vomiting are major priorities for day-case patients. Anaesthetists should take patients' preferences into consideration when developing guidelines and planning anaesthetic care.

SummaryWe studied 128 patients undergoing nasal intubation to see whether the nostril side used influenced peri-operative nasal complications. In the apparently normal nostril, there is no significant difference between either nostril in difficulty of intubation ( p . 0.8). Similarly, there is no significant difference in the incidence of bleeding at intubation ( p . 0.2), at extubation ( p . 0.5) and once the patient has returned to recovery ( p . 0.1). Postoperative nostril patency is also similar between groups ( p . 0.85). Standard teaching of nasal intubation recommends that, in the first instance, the right nostril should be used when patency appears equal on both sides of the nose [1]. This is because the tracheal tube is designed such that the flat side of the bevel is on the left side of the tip. However, there is no evidence that the risk of trauma to the nose, or difficulty with intubation, is any greater using the left nostril. Many case reports of potentially serious complications of nasal intubation have in fact involved the right nostril [2±4].Our study aimed to elucidate whether the left nostril was more difficult to intubate than the right and whether the complications, in terms of bleeding and postoperative nostril patency, were different between the two sides. MethodAfter approval from the Hospital Research Ethics Committee, we studied 128 patients who were undergoing elective dental surgery that required nasal intubation. Patients were ASA classification 1 or 2. They had no history of nasal disease, including epistaxis, no coagulation problems, and were not taking medication likely to increase bleeding. None of the group had hypertensive disease. Patients were not studied if there was apparent unilateral decrease in nostril patency, determined by breathing through each nostril individually.A standard anaesthetic technique was used. Premedication with diclofenac 100 mg rectally was given up to 30 min before surgery. Induction and maintenance of anaesthesia was performed using a combined propofol (500 mg)/alfentanil (2 mg) infusion, with atracurium 0.3 mg.kg 21 given to facilitate intubation. Ventilation throughout anaesthesia was provided using an oxygen/ nitrous oxide mixture.The nostril side for intubation was chosen randomly and no vasoconstrictor spray was used. Intubation was performed using a Portex`Ivory' cuffed nasotracheal tube lubricated with water-soluble jelly. A tube with an internal diameter of 6.5 mm was used for men and 6 mm for women. The tube was passed through either nostril with the slant of the bevel facing to the left. The ease of passing the tube through the nostril was noted. Once the tip of the tube had passed into the oropharynx, direct laryngoscopy was performed and the presence of blood in the pharynx was noted. This was classified as either (1) blood absent, (2) blood staining on the cuff only (mild bleeding) or (3) blood pooling on the posterior pharyngeal wall (severe bleeding). The tube was then passed into the trachea under direct vision, the cuff was inflated ...
