Nasal continuous positive airway pressure (CPAP) is the mainstay of treatment for patients with moderate to severe obstructive sleep apnoea (OSA). However, tolerance and compliance are poor.An audit using the Christchurch Hospital ORL surgery database identified patients who underwent upper airway surgery for OSA. Tracheostomy and bimaxillary advancement patients were excluded. Adults with moderate to severe OSA (Desaturation Index (DI) >10 n.h-1), who had failed atrial of nasal CPAP, and had pre-operative and post-operative sleep study data were identified. Objective (DI) and Subjective (Epworth Sleepiness Score (ESS)) outcome measures were recorded.The database identified 69 patients who underwent surgery for snoring or OSA; of these, 25 patients formed the study group. Sixteen out of 25 improved (64 per cent) after surgery, seven out of 25 showed no change (28 per cent), two patients (eight per cent) showed deterioration in their DI. Forty-eight per cent of patients had >50 per cent post-operative improvement in DI. Fourteen out of 25 (56 per cent) had a post-operative DI <20 n.h-1. Seven out of 25 (28 per cent) had a post-operative DI <10 n.h-1. Upper airway surgery has a role in the managementof selected patients with OSA who cannot tolerate nasal CPAP.

In obstructive sleep apnea (OSA), the short-latency inhibitory reflex (IR) of inspiratory muscles to airway occlusion is prolonged in proportion to the severity of the OSA. The mechanism underlying the prolongation may relate to chronic inspiratory muscle loading due to upper airway obstruction or sensory changes due to chronic OSA-mediated inflammation. Continuous positive airway pressure (CPAP) therapy prevents upper airway obstruction and reverses inflammation. We therefore tested whether CPAP therapy normalized the IR abnormality in OSA. The IR responses of scalene muscles to brief airway occlusion were measured in 37 adult participants with untreated, mostly severe, OSA, of whom 13 were restudied after the initiation of CPAP therapy (usage >4 h/night). Participants received CPAP treatment as standard clinical care, and the mean CPAP usage between initial and subsequent studies was 6.5 h/night (range 4.1-8.8 h/night) for a mean of 19 mo (range 4–41 mo). The duration of the IR in scalene muscles in response to brief (250 ms) inspiratory loading was confirmed to be prolonged in the participants with OSA. The IR was assessed before and after CPAP therapy. CPAP treatment did not normalize the prolonged duration of the IR to airway occlusion (60 ± 21 ms pretreatment vs. 59 ± 18 ms posttreatment, means ± SD) observed in participants with severe OSA. This suggests that the prolongation of IR reflects alterations in the reflex pathway that may be irreversible, or a specific disease trait.

Abstract The high risks associated with general anesthesia in obstructive sleep apnea syndrome (OSAS) patients have been reported. Many authors have suggested that the intraoperative administration of opioids and sedatives should be limited or avoided because these drugs selectively impair muscle activity in the upper airway. We report the case of an OSAS patient who was managed with nasal continuous positive airway pressure (NCPAP) and treated safely in spite of the use of conventional anesthetic and analgesic agents typically used for patients without OSAS. She had little pain during the perioperative period. It is suggested that NCPAP is an effective treatment for not only preventing airway obstructive apnea but for allowing the administration of anesthetic and analgesic drugs without major complications.
