A comparison of xylometazoline (Otrivine) and phenylephrine/lignocaine mixture (Cophenylcaine) for the purposes of rigid nasendoscopy: a prospective, double-blind, randomised trial.

OBJECTIVE: To evaluate if phenylephrine-lignocaine mixture (Cophenylcaine) nasal spray performs better than xylometazoline (Otrivine) spray for the purposes of out-patient rigid nasendoscopy preparation. DESIGN: Prospective, double-blind, randomised trial comparing visual analogue scores for out-patients receiving either phenylephrine-lignocaine mixture or xylometazoline, prior to undergoing rigid nasendoscopy as part of their assessment. SUBJECTS: Seventy-three patients requiring rigid nasendoscopy as part of their assessment were recruited to the study from Raigmore Hospital's out-patient clinic. These patients were randomised to receive a nasal spray comprising either phenylephrine-lignocaine mixture or xylometazoline, 10 minutes prior to rigid nasendoscopy. Double-blinding was adopted. After the procedure, the patient and the doctor independently completed separate visual analogue score-based questionnaires regarding the pain of the procedure and the ease of the examination, respectively. RESULTS: Analysis of the data using standardised statistical methods demonstrated that the phenylephrine-lignocaine mixture did not perform better than xylometazoline, to any statistically significant extent. CONCLUSION: Phenylephrine-lignocaine mixture is considerably more expensive and has potentially more side effects than xylometazoline. These study findings suggest that it is difficult to justify the use of phenylephrine-lignocaine mixture over xylometazoline, for nasal preparation prior to rigid nasendoscopy.

'Group and save' for paediatric tonsillectomy: is it required routinely?

OBJECTIVES: The aims of this study were: (1) to establish current UK practice with respect to 'group and save' of serum for paediatric tonsillectomy; and (2) to determine the need to group and save serum prior to routine paediatric tonsillectomy. METHODS: Members of the British Association of Otorhinolaryngologists-Head and Neck Surgeons were surveyed by e-mail. A prospective study (November 1999 to August 2002) of all children undergoing tonsillectomy or adenotonsillectomy was undertaken. Outcome measures included reactionary and secondary post-tonsillectomy haemorrhage rates, blood transfusion requirements and 'return to theatre' rates. RESULTS: We surveyed 464 association members. The response rate was 52 per cent (n=242). Twenty-five respondents (10.3 per cent) indicated that they undertook group and save prior to tonsillectomy or adenotonsillectomy in children. Two hundred and seventeen (89.7 per cent) indicated that they did not. Of those who did group and save for children, 20 respondents (80 per cent) did so routinely. The remaining five respondents (20 per cent) did so only for children weighing less than 15 kg (n=4) or less than 10 kg (n=1). During the study period, 325 children underwent tonsillectomy or adenotonsillectomy. The reactionary haemorrhage rate was 0.6 per cent (n=2) and the secondary haemorrhage rate 5.5 per cent (n=18). The two cases of reactionary haemorrhage were returned to theatre immediately for control of haemostasis. All secondary haemorrhages were managed conservatively. No child required blood transfusion during the study period. CONCLUSION: Routine group and save of serum for children undergoing elective tonsillectomy or adenotonsillectomy seems unnecessary. We recommend that it be undertaken only in special circumstances.

The influence of weather on the frequency of secondary post-tonsillectomy haemorrhage.

The aim of this study was to determine whether certain weather variables influence the secondary post-tonsillectomy haemorrhage rate and to examine the influence of a change in these variables on secondary haemorrhage. This was a prospective study carried out in a tertiary referral institution. All patients undergoing bilateral tonsillectomy over a one-year period were included. Local weather data, including daily temperature (max/min), relative humidity and water vapour pressure, were acquired. All patients readmitted to our department with secondary post-tonsillectomy haemorrhage were recorded. Of 346 patients undergoing tonsillectomy, 32 developed secondary haemorrhage (9.2 per cent). A significant negative correlation was found between secondary haemorrhage rate and the average monthly temperature (max/min) and water vapour pressure (Pearson's correlation = -0.8) (p < or = 0.002). These results suggest that performing tonsillectomy in warmer weather when the water vapour pressure is higher may reduce the secondary haemorrhage rate.

Student-perceived benefit from otolaryngology theatre attendance.

The value of theatre attendance by undergraduates is uncertain. This study aimed to evaluate the perceived benefits of attending operating theatre sessions during undergraduate otolaryngology attachments. The study comprised a questionnaire survey carried out in a university medical school. Fourth-year medical students were asked to complete a questionnaire at the end of their two-week attachment in otolaryngology. Completed questionnaires were returned by 152 students. The three most common student expectations were to see and learn common ENT operations, to see the anatomy involved and to learn about the disease being operated upon. Sixty per cent of students reported that their expectations had been met. On a Likert scale from 1 (strongly disagree) to 7 (strongly agree), the importance of theatre attendance as part of the curriculum was rated to be 4.7 (95 per cent confidence interval (CI) = 3.7 to 4.2) and the satisfaction of educational needs in operating theatre teaching was rated to be 3.9 (95 per cent CI = 3.7 to 4.2). Students perceived attending otolaryngology theatre sessions to be beneficial. This information is important in the planning of the otolaryngology undergraduate curriculum.

Diagnostic and therapeutic use of the flexible nasendoscope in the management of an impacted upper oesophageal food bolus.

The flexible nasendoscope is now an integral tool in most otorhinolaryngology departments for visualizing the hypopharyngolarynx. A technique has been described using the modified Valsalva manoeuvre to improve visualization of the hypopharynx during flexible nasopharyngoscopy. The authors report an alternative technique for visualizing the upper oesophagus using the flexible nasendoscope, and highlight three cases where there was accurate visualization of an impacted oesophageal food bolus. Subsequently, these patients underwent flexible oesophagoscopy to dislodge the foreign body. The authors also describe three cases where the flexible nasendoscope was successfully used to visualize and negotiate the impacted food bolus beyond the cricopharyngeus. This is a safe and simple procedure performed without any sedation and reduces the need for prolonged hospitalization.

Staff attitudes to a daily otolaryngology ward round.

This survey investigates the attitudes of medical and nursing staff towards the daily otolaryngology ward rounds in a teaching hospital. Initial, open-ended questionnaires generated themes from which a structured questionnaire was constructed. Respondents indicated on a Likert scale the extent to which they agreed or disagreed with statements concerning their attitudes towards the ward round. Thirty-five members of staff were surveyed. The overall response rate was 74.3 per cent (n = 26). The majority of staff agreed that the ward round was a constructive use of their time and served to promote team spirit. It allowed for adequate communication between medical and nursing staff but there was uncertainty about the provision of adequate patient communication. The nursing staff agreed that the ward round provided a valuable learning experience. There was uncertainty about this among the medical staff. There was agreement in both groups that patients find the ward round to be reassuring. A significant majority of staff expressed concerns over maintenance of patient confidentiality. These findings could be used to inform changes in the departmental ward round structure. Specific attention should be directed to discussing sensitive issues in a more private setting and maximizing educational opportunities for junior medical staff.

Nasal septal perforation repair using open septoplasty and unilateral bipedicled flaps.

The aim of this study was to assess the success of the technique of open septoplasty with bipedicled flaps in achieving long-term closure and control of symptoms. Between 1993 and 2000, 32 patients underwent surgery for nasal septum perforation. Twenty patients with large perforations underwent posterior edge repair only. The remaining 12 patients (five female, and seven male) with perforations less than 20 mm in diameter underwent open septoplasty and a unilateral bipedicled flap closure. A retrospective review involving a symptom scores assessment and follow-up examination was conducted. One patient died of unrelated illness, and was excluded. Results showed 10 of the remaining 11 patients achieved closure after a mean follow up of 10 months. The symptoms of crusting (p < 0.0001), epistaxis (p < 0.02), discharge (p < 0.012), whistling (p < 0.011), and overall discomfort (p < 0.02), were all significantly improved. We conclude that by using this technique on patients with small perforations less than 20 mm, it is possible to achieve up to a 90 per cent perforation closure rate, and a significant improvement in patients' symptoms.

The admission of patients with peri-tonsillar abscess to a general ENT ward and its influence on secondary post-tonsillectomy haemorrhage.

Patients with peri-tonsillar abscess require hospitalization. The aim of this prospective study was to determine whether the admission of patients with peri-tonsillar abscess to the same ward as those undergoing tonsillectomy influences the incidence of secondary post-tonsillectomy haemorrhage. We included all adult patients undergoing in-patient tonsillectomy (n = 183) and all patients with proven peri-tonsillar abscess (n = 46) over a 1-year period. Both patient groups were nursed in the same general otolaryngology ward. The operation dates of those patients who developed secondary post-tonsillectomy haemorrhage were matched to the dates when patients with peri-tonsillar abscess were admitted. Out of the 71 patients who had tonsillectomy on days when patients with peri-tonsillar abscess were admitted, 10 developed secondary haemorrhage. Out of the 112 patients who had tonsillectomy on days when no one in the ward had peri-tonsillar abscess, 16 developed secondary haemorrhage. No difference was demonstrated (chi2 = 0.0014, P > 0.05). In this study, admission of patients with peri-tonsillar abscess to a general otolaryngology ward does not influence the incidence of secondary post-tonsillectomy haemorrhage in patients undergoing elective surgery.
