Experimental Study of Music Intervention on Mechanical Ventilation Patients

Objectives: To examine the effects of music intervention on the variables and the anxiety level of mechanically ventilated patients in ICU.Methods: A total of 197 patients receiving mechanical ventilation were randomly assigned to music group, headphone group or control group depending on the sequence of participation. SPSS 11.0 For Windows was used for all data analysis. Results: 1) baseline data: Each group of object of study's baseline data does not have statistics difference (P>0.05), the baseline data is consistent, has the commeasurability. 2) physiological target: The heart rate, the breathing rate two target music intervention group, the earphone control group patient 3 time section heart rate's difference has statistics significance(P<0.05). Blood pressure: music intervention group before the experiment, 10 minute, 25 minutes systolic blood and pressure diastolic pressures are dorpped, the Variance analysis demonstration by statistics significance (P<0.05). 3) anxious level: Compares before the intervention, after the intervention, around music intervention group, the earphone control group, the blank control group's condition anxious score from 49.28, 51.42. 50.92 points dropped 40.10, 44.89,46.00 points separately, music intervention group has intervened the anxious differential value to have statistics significance P < 0.05. Conclusion: 1) music intervention has the stable machinery to ventilate physiological target and so on patient heart rate, breathing rate, systolic pressure and diastolic pressure functions. 2) music intervention with wears the earphone to have reduces the machinery to ventilate the patient anxious level function. 3) compares with the earphone control group, music intervention reduces the machinery to ventilate the patient anxious level the function to be more remarkable. 4) the Uygur and Han Nationality machinery ventilates the patient music intervention group to have the stable machinery to ventilate physiological targets and so on patient heart rate, breathing rate, systolic pressure and diastolic pressure and reduces the anxious function.
