Seventy-eight workers, drawn from a population of 1502 presumably healthy working men who were interviewed about sleep habits and sleep disorders, underwent polygraphic recordings for at least 1 night. A significant association was found between the complaint of excessive daytime sleepiness and the incidence of sleep apnea. Workers with more than 10 apneas per hour of sleep complained significantly more about loud snoring, hypermotility in sleep, and frequent headaches. They had significantly more ENT findings and hypertension.

1. Vomiting and restlessness following ENT and eye surgery are undesirable, and may be related to the emetic and analgesic effects of any analgesic given to augment anaesthesia during surgery. 2. To rationalise the choice of analgesic for routine ENT surgery we examined the intraoperative, recovery and postoperative effects following the administration of either buprenorphine (3.0 to 4.5 micrograms kg-1), diclofenac (1 mg kg-1), fentanyl (1.5 to 2.0 micrograms kg-1), morphine (0.1 to 0.15 mg kg-1), nalbuphine (0.1 to 0.15 mg kg-1), pethidine (1.0 to 1.5 mg kg-1) or saline (as control) given with the induction of anaesthesia in 374 patients. A standardised anaesthetic technique with controlled ventilation using 0.6-0.8% isoflurane in nitrous oxide and oxygen was employed. The study population constituted 7 similar groups of patients. 3. Intraoperatively, their effects on heart rate and blood pressure, airway pressure and intraocular pressure, were similar. This implies, most surprisingly, that neither their analgesic nor their histamine releasing effects were clinically evident during surgery. By prolonging the time to extubation at the end of anaesthesia, only buprenorphine, fentanyl, morphine and pethidine provided evidence of intraoperative respiratory depression. 4. Postoperatively, buprenorphine was associated with severe respiratory depression, prolonged somnolence, profound analgesia and the highest emesis rate. Diclofenac exhibited no sedative, analgesic, analgesic sparing, emetic or antipyretic effects. Fentanyl provided no sedative or analgesic effects, but was mildly emetic. Morphine provided poor sedation and analgesia, delayed the requirement for re-medication and was highly emetic. Nalbuphine and pethidine produced sedation with analgesia during recovery, a prolonged time to re-medication and a mild emetic effect. None provided evidence, from analysis of postoperative re-medication times and analgesic consumption, of any pre-emptive analgesic effect. 5. We conclude that nalbuphine (mean dose 0.13 mg kg-1) and pethidine (mean dose 1.35 mg kg-1), given individually as a single i.v. bolus during induction of anaesthesia, are the most efficacious analgesics for routine in-patient ENT surgery.

Obesity, short stature, hypotonia and excessive daytime sleepiness are characteristic features of the Prader-Willi syndrome. Excessive daytime sleepiness has been attributed to obstructive sleep apnoea (OSA). To investigate the role of anatomical factors in OSA in the Prader-Willi syndrome, clinical and ENT assessment, radiology of the upper airway and polysomnography including sleep oximetry were done in 14 subjects. Excessive daytime sleepiness was present in eight of 14 subjects as determined by a mean sleep latency to non-rapid eye movement stage I-II of < 5 min and/or self-rating sleepiness score > 9 (Epworth Sleepiness scale). Seven subjects were snorers or mouth breathers and dental abnormalities were present in 11. Sleep apnoea, as determined by a combined apnoea-hypopnoea index of more than 10 respiratory events per hour was present in 12 of 14 subjects. On clinical assessment, the nasopharynx, oropharynx and hypopharynx were small in one subject. No subject had redundant pharyngeal mucosa or an enlarged tongue. However, radiological studies performed in the awake supine posture showed a slight reduction in the cross-sectional area in nine subjects at the oropharyngeal level and in four subjects at the nasopharyngeal level as compared with normal control subjects. Sleep apnoea and minor radiological evidence of narrowing of the upper airway are common in the Prader-Willi syndrome, although clinical otolaryngological examination is often unremarkable. Excessive daytime sleepiness occurs in approximately 50% of all patients with Prader-Willi syndrome. Although obstructive sleep apnoea is one important factor related to sleepiness, an additional central disturbance of sleep mechanisms is present.

Diagnosis of a sleep apnoea syndrome in severely snoring patients with diurnal sleepiness is growing in importance in the consulting rooms of general practitioners, internists, ENT specialists and pneumologists. However, time and cost reasons limit the diagnostic procedures conducted by practitioners to outpatient screening. Two different systems are presently available in Germany. The MESAM system (Madaus, Freiburg) records by means of a microphone and various electrodes the oxygen saturation, heart rate, snoring and sleeping position of the patient. The Apnoe-Check System (Medanz, Starnberg) determines the nasal and oral respiratory flow by means of a mask fitted with thermistors. Evaluation is accomplished in the case of MESAM via a conventional personal computer whereas with the Apnoea Check System the apnoeas and their duration can be read off direct from a writer. The cost ratio of these systems is approximately 3:1 (MESAM:Apnoea Check). Wie compared both systems by parallel measurements on 19 female and male patients and controlled the results obtained by measurements with a CO2 infrared absorption spectrometer in our sleep lab. A total of 3201 nocturnal events were recorded via MESAM and 1488 via the Apnoe-Check System. The highest number of apneas was recorded by MESAM in a patient with severe sleep apnea syndrome, namely, 546 apnoeas in one night. The lowest number of apnea events was experienced by a healthy male with 33 apneas in a night. With the Apnoe Check the maximum of nocturnal events was 255, the minimum being 8 events in one patient. In 64.6% of all nocturnal events there was time congruence for both systems.(ABSTRACT TRUNCATED AT 250 WORDS)

Obstructive sleep apnoea syndrome is due to pharyngeal obstruction of inspiratory airflow with preservation of thoraco-abdominal respiratory movements. This disease has been described for about thirty years, but is now the subject of growing interest. According to the increasingly abundant literature on this subject, OSAS is associated with essentially cardiovascular morbidity and mortality (systemic hypertension, pulmonary hypertension, heart failure, coronary heart disease, arrhythmias, cerebral vascular accidents and sudden death). The pathophysiology of its underlying mechanisms and its complications is complex and multifactorial. The diagnosis of this syndrome should be suspected on clinical interview (snoring, excessive daytime drowsiness, and apnoea during sleep) and is confirmed by polysomnography. Nasal continuous positive pressure with elimination of aggravating factors is the reference treatment in 1994. The diagnosis and management of this syndrome requires a multidisciplinary approach with collaboration between general practitioners, neurologists, maxillofacial/ENT surgeons, cardiologists and respiratory physicians.

The prevalence of sleep-disordered breathing (SDB) was evaluated in a male population sample of Lorraine (university staff), with a protocol including a self-completed standardized questionnaire, anthropometry (including neck, waist and hip circumferences) and non-invasive ear, nose, and throat examination. Among 357 subjects present in the institution at the moment of the survey, 334 (93.6%) accepted to participate, and 300 (84%) returned the questionnaires. The anthropometric results corresponded to the French normative values according to gender and age. We chose a value of 32 as limit of the body mass index (BMI) between weight excess and obesity; this limit was exceeded by 7.2% of the subjects. The mean age of the sample was 44.8 (SD 10.1) years; the waist-to-hip ratio was of 0.907 +/- 0.053. The ENT examination found a high prevalence of nasal septum deviations (52.6%), of soft palate (25.2%), and uvula (42%) abnormalities; 32.1% of the subjects had experienced amygdalectomy. The non-responses to the questionnaire were infrequent (less than 2%), except for the questions regarding a history of hypertension (2.6%), weight fluctuations the last 5 years (7.6%), and the number of years in school (12%). The questionnaire included, for each question, the optional answer "don't know"; this answer was chosen for the questions concerning the duration of snoring (37.1%), stopping breathing during sleep (12.7%) and the parental history of narcolepsy (18.7 and 20.7%) and sleep apnoea (33.7 and 36.4%). 5.7% of the subjects declared sleep apnoeas at least once per week: 16.1% had unrefreshing sleep; 10.6% admitted to excessive daytime sleepiness; 41.9% were habitual snorers. These results indicate a prevalence of SDB in our sample which is comparable to the figures obtained in other European studies. Further analysis of our data will indicate if, besides weight excess and its troncular distribution, cigarette smoking and respiratory symptoms, the "minor" ENT abnormalities play a role in the pathogenesis of SDB.

ENT specialists are now being asked for help by increasing numbers of snoring patients who complain about nocturnal apnea and excessive daytime sleepiness. A final diagnosis is often made in a sleep disorders center. Sleep medicine has emerged as a new inter-disciplinary specialty during the last decade, although otorhinolaryngologists commonly are unable to fully interpret clinical findings. This report discusses the terms and information often detailed at a sleep disorders center. The evaluation of diagnostic and therapeutic procedures is explained.

Snoring is a common disorder and may lead to the development of Obstructive Sleep Apnoea (OSA) with its associated hazards. Differentiation of patients with OSA from patients with simple snoring is crucial to the ENT surgeon before selecting treatment. This study aimed to assess the reliability of the Epworth Sleepiness Scale (ESS) to screen for OSA among snorers. Forty-six patients referred for treatment of snoring were studied. Each patient completed the ESS questionnaire and subsequently underwent a hospital sleep study. The ESS scores did not correlate with the apnoea/hypopnoea indices calculated from the sleep studies (correlation coefficient 0.12). The lack of correlation is mainly because simple snorers can also suffer from excessive daytime sleepiness, due to an unclear mechanism. The ESS is a useful questionnaire for assessing disability as a result of snoring but it is of no value in distinguishing simple snorers from patients with OSA.

As a result of a previous audit on the management of sleep apnoea hypopnoea syndrome (SAHS) which showed long waiting times that were primarily due to unnecessary interspecialty referrals, a change in practice was adopted. All referrals are now sent a questionnaire about symptoms suggestive of SAHS, the Epworth Sleepiness Scale score and their body mass index (BMI) which when returned are categorized into having a high, intermediate or low risk of SAHS. Those patients with a high probability have home overnight oximetry and those with intermediate probability have video oximetry. Those with a low probability are referred directly to ENT. We audited the first 100 patients referred. All were General Practitioner referrals to either ENT or respiratory medicine. Only two patients had a low probability score and were seen directly in ENT. Following sleep study analysis, 10 patients were referred directly to ENT with no respiratory medicine follow-up and nine were discharged back to the General Practitioner with no apnoea or snoring. Eighty-one patients were followed up by respiratory medicine. Of these, 49 received a trial of nasal continuous positive airway pressure (nCPAP) and six were referred to ENT. Therefore the majority justified an investigation to exclude SAHS in the first instance and an unnecessary initial ENT appointment was avoided. We have reduced the average waiting times to sleep study by approximately 90 days and to nCPAP trial by 32 days, mostly due to decreased delays in interspeciality referrrals. We have also demonstrated a greater than 50 per cent reduction in ENT clinic visits, a small increase in the number of sleep studies but no increase in respiratory clinic workload.
