The first part of OSAHS patients preoperative evaluation purposes: obstructive sleep apnea hypopnea syndrome (obstructive sleep of apnea to-hypopnea syndrome, OSAHS) patients to make a more comprehensive and accurate preoperative assessment, in order to reduce the risk of perioperative. Methods: general 106 OSAHS patients before surgery, the functional status of the organs and the airway to observe the patient's mouth opening, Mallampati class, submental A distance, the length of the horizontal branch of the mandible, the atlanto-occipital joint degree of stretching BMI (body mass index, BMI), neck circumference, sleep apnea hypopnea index (of apnea to-hypoventilation index, AHI), Cormack-Lehane (CL) grading and mask ventilation conditions to select the method of induction of anesthesia. Results: circulatory, respiratory, liver, endocrine system complication, which is mostly in hypertension in 30 cases (28%), followed by ECG abnormalities in 15 patients (14%); body physically healthy situation ASA (American Society of Anesthesiologists) grade Ⅰ, 43 cases (41%), grade II in 63 cases (59%). Intubation difficult patients, 3 patients (3%), possible intubation difficult 103 patients (97%); CL grading Ⅳ (absolute difficult intubation), 2 patients expected four cases of difficult mask ventilation ; the fiberoptic bronchoscopy sober intubation 6 patients, 100 patients with rapid sequence intubation. CONCLUSION: OSAHS patients is often associated with multiple organ damage and more for difficult airway, should make accurate preoperative evaluation to determine the induction of anesthesia, reduce the risk of anesthesia management. The second part of the GlideScope video laryngoscope for clinical research purposes OSAHS patients with nasal intubation: To observe the GlideScope video laryngoscope and Macintosh laryngoscope for obstructive sleep apnea hypopnea syndrome (OSAHS) patients nasotracheal interpolation glottis exposure tube, intubation, number of intubation time and hemodynamic changes. Methods: 100 cases of OSAHS patients assessed feasible rapid sequence intubation, divided into GlideScope video laryngoscope group and Macintosh direct laryngoscope group. The General observed of recording two groups of patients, the throat revealed Cormark-Lehane (CL) grading, intubation times, intubation time, and before and after intubation heart rate, blood pressure, and calculated for each point in time, heart rate - pressure product (RPP ). Results: the proportion of grade Ⅰ ~ Ⅱ grade using the GlideScope video laryngoscope CL and time intubation success rate as high as 96% and 98%, while the Macintosh laryngoscope group compared with 47% and 84%, the difference between the two groups statistically significant. GlideScope video laryngoscope intubation time group (41.7 ± 14.8) s, shorter than the Macintosh laryngoscope group (51.3 ± 21.0) s. After induction of anesthesia, the two groups of patients with blood pressure and RPP than before induction of anesthesia reduced, no significant changes in heart rate. Two groups of patients with elevated heart rate than 2min after intubation before induction of anesthesia and endotracheal intubation; blood pressure and RPP increased within 1min after intubation compared with before induction of anesthesia and endotracheal intubation. Before the difference between the two groups of patients in the intubation of the trachea and heart rate and blood pressure after intubation with anesthesia induced comparison between groups, the difference was not statistically significant. Conclusion: GlideScope video laryngoscope for OSAHS patients may improve nasal intubation laryngeal exposure classification, improve time intubation success rate and shorten the time required endotracheal intubation, hemodynamic changes with the Macintosh laryngoscope similar.
