ABSTRACT:
OBJECTIVES- 1) To assess the airway clearance of patients on mechanical ventilator in experimental and control group in selected hospitals. 2) To assess the effectiveness of hypertonic saline nebulized suctioning on airway clearance of patients on mechanical ventilator in experimental group in selected hospitals. HYPOTHESIS: H0 – There will be no significant difference in the effectiveness of hypertonic saline nebulized suctioning on airway clearance of patients on mechanical ventilator in experimental group in selected hospitals. H1 - There will be a significant difference in the effectiveness of hypertonic saline nebulized suctioning on airway clearance of patients on mechanical ventilator in experimental group in selected hospitals. METHODOLOGY: The research approach adopted in this study is Quantitative experimental approach. Quasi experimental two groups, pre-test & post-test design selected for this study. The sample size of the present study were 40 mechanical ventilated patient in selected hospitals. In this study non-probability purposive sampling was adopted to select the subjects. RESULT: The above table shows Age wise distribution in control group maximum subjects 9(45%) belongs to above 51 yrs and minimum 3(15%) were in between 31-40 yrs. In experimental group maximum subject 10(50%) of them were above 51 yrs and minimum 3(15%) were in age between 31-40 yrs. Gender wise distribution in control group maximum subjects 11(55%) were male and minimum 9 subject (45%) were female. In control group maximum subject 14(70%) were male and 6(30%) were female. Duration of ventilator wise distribution in control group maximum subjects 15(75%) were between 2-5 days and minimum 5(25%) between 6-9 days. In experimental group maximum subject 10(50%) between 2-5 days and minimum 1(5%) were between 10-13 days. Habit wise distribution in control group maximum subjects 11(55%) of them had no habit and minimum 3(15%) were having alcohol consumption habit. In experimental group maximum subject 9(45%) had no habit and minimum 1(5%) had tobacco consumption habit. Occupation wise distribution in control group maximum subject 9(45%) were labourers and minimum 2(10%) were cotton industry workers. In experimental maximum subject 11(55%) were labourers and minimum 1(5%) were cotton industry workers. Area of living wise distribution in control group maximum subject 13(65%) were living in rural area and minimum 7(35%) in urban area. In experimental group maximum subject 13(65%) were living in urban area and minimum 7(35%) were living in rural area. The pre test mean and SD of heart rate in control group is 90.3 and 5.55 and the pre test mean and SD of heart rate in experimental group is 100.40 and 16.31. The pre test mean and SD of Respiration in control group is 22.65 and 1.79 and the pre test mean and SD of Respiration in experimental group is 24.35 and 2.41. The pre test mean and SD of Spo2 in control group is 94.9 and 2.80 and the pre test mean and SD of Spo2 in experimental group is 96.30 and 2.13 respectively. 1. Repeated measures ANOVA test was carried out. The finding shows that in control group pre test mean of heart rate was 90.3 and S.D was 5.55. The post test 1 mean was 88.00 and SD 6.61. The post test 2 mean was 89.8 and SD was 7.07. The post test 3 mean was 91.5 and SD 7.99. The test statistic value of ANOVA was 1.71. The p value was 0.17. The finding shows that in control group pre test mean of Respiration was 22.65 and S.D was 1.79. The post test 1 mean was 22.80 and SD 1.51. The post test 2 mean was 23.30 and SD was 1.87. The post test 3 mean was 23.30 and SD 0.98. The test statistics value of ANOVA was 1.73. The p value was 0.17. The finding shows that in control group pre test mean of Spo2 was 94.9 and S.D was 2.80. The post test 1 mean was 94.95 and SD 2.88. The post test 2 mean was 94.05 and SD was 2.99. The post test 3 mean was 95.25 and SD 2.31. The test statistics value of ANOVA was 0.72. The p value was 0.54. Above study findings revealed that there is no significant difference in the effectiveness of hypertonic saline nebulized suctioning on airway clearance in control group. 2. Repeated measures ANOVA test was carried. The finding shows that in experimental group pre test mean of heart rate was 100.40 and S.D was 16.31. The post test 1 mean was 94.95 and SD 13.72. The post test 2 mean was 88.30 and SD was 7.69. The post test 3 mean was 86.30 and SD 8.29. The test statistics value of ANOVA was 20.57. The p value was <0.0001. The finding shows that in experimental group pre test mean of Respiration was 24.35 and S.D was 2.41. The post test 1 mean was 23.20 and SD 1.51. The post test 2 mean was 21.50 and SD was 1.57. The post test 3 mean was 21.10 and SD 1.37. The test statistic value of ANOVA was 31.28. The p value was <0.0001. The finding shows that in experimental group pre test mean of Spo2 was 96.30 and S.D was 2.13. The post test 1 mean was 97.60 and SD 1.70. The post test 2 mean was 98.90 and SD was 1.21. The post test 3 mean was 99.75 and SD 0.65. The test statistics value of ANOVA was 29.8. The p value was <0.0001. CONCLUSION: The above interventional study was a good learning experience for the investigator. The result of this study showed that hypertonic saline nebulized suctioning was effective on airway clearance among mechanical ventilated patients thus the null hypothesis (H0) was rejected and (H1) was accepted. Hypertonic saline nebulized suctioning used in clinical setting for patients in selected hospitals was effective.
