Methods: a total of 364 Cases who would be undergoing colonoscope examination were equally divided into both test group and control group. Patients of 182 cases in test group were given mixed gas (half of laughing gas and half of oxygen) for analgesia during their examination. While the control group patients were conducted the examination just as routine. Indexes including the intensity of pain, manipulation time, the success rate of examination, oxygen saturation, and heart rate changes of the two groups patients before, during and after the examination were observed. Results: in terms of the analgesic effect, manipulation time, and the success rate of examination, patients of test group were superior to those of control group (P<0.01).There was no significance in both oxygen saturation and heart rate changes between test group and control group patients (P>0.05).Conclusion: analgesic effect of nitrous oxide is good. It is also safe, effective, convenient, non-invasive in manipulation. It could promote the success rate of patients undergoing colonoscope examination.
