Poster Presentations P195 POSTERSThese clips can hold various sucker sizes as they feature an expandable slit. With this clip, the placement of the sucker in the proximal end of the laryngoscope and the position of the sucker tip at the distal end are both easily adjustable for optimal suction. It also clips easily into any laryngoscope without obscuring visual field. Furthermore, in the instance of any bleeding, this sucker is easily detachable and can be used for suction. Conclusion:We routinely use these sucker clips to perform all endolarygneal surgery and overall, feel they are simple, easy to use, and extremely efficient in suctioning fumes.

Objectives: 1) Evaluate the accuracy of Watch PAT in diagnosing sleep-disordered breathing (SDB). 2) Compare the results of Watch PAT and polysomnography (PSG). Methods: Prospective study performed between February and December 2012. Thirty patients with suggestive complaints of respiratory sleep disorder underwent Watch PAT and polysomnography simultaneously. Results: Twenty men and ten women underwent the sleep studies. Mean age was 42.8 ± 12.32 years. There was a trend that the apnea / hypopnea index (AHI) of Watch PAT was significantly higher than that of PSG (p<0.001); however the values of AHI of both sleep studies were significantly correlated (r = 0.762). There was also a high correlation between the values of the following variables: minimum oxygen saturation (r = 0.842, p<0.001), oxygen saturation <90% (r = 0.799, p <0.001), and mean heart frequency (r = 0.951, p <0.001). The analysis which used ROC curve to test the diagnostic efficiency of Watch PAT concluded that the area under the curve could reach 0.727 if the threshold of 12 events/hour was used as the cut-off point in this study with a sensitivity of 96.2% and a specificity of 60%. When analyzing the severe cases of obstructive sleep apnea (OSA) (AHI ≥ 30 events/hour), the area under the curve was 0.846 with a sensitivity of 77.8% and a specificity of 86.4%. Conclusions: Watch PAT tends to overestimate the AHI when compared with PSG, especially for mild OSA. The Watch PAT is an alternative method that is reliable and highly sensitive for the diagnosis of SDB.
