Results: 1) observation group patients’ blood glucose values after water fasting were significantly higher than control group patients (t=5.382, t=5.893, t=6.624, t=7.934; P0.05), SAS and SDS scores of observation group patients 1h before the examination and inspection were significantly lower than the control group patients (t=6.382, t=6.562, t=4.958, t=7.632;P<0.05). Conclusion:Two hours before bronchoscopy is more conducive to the maintenance of water fasting blood sugar stable patients, reduce stress levels, relieve negative emotions in patients with positive clinical significance.
