ABSTRACT:

Introduction: Advanced technology is a major part of the ICU and mechanical ventilation (MV) is one of the most commonly used treatment modalities in the care of the critically ill patient. Up to 90% of patients globally require mechanical ventilation (MV) during some or most part of their stay in the ICU. Mechanical ventilation (MV) is a key component in the care of critically ill and injured patients. Delays in weaning the patient from MV increase the number of complications and may lead to increased expenditure. Consequently, weaning constitutes a major challenge for the intensive care staff. It is important to wean the patient from MV as expeditiously as possible. Several studies indicate that the implementation of nurse-led, protocol-directed weaning reduces the amount of time spent on MV, the length of ICU stay, and associated costs. Objectives of the study: The purpose of the study was to assess the effect of video assisted programme on knowledge regarding weaning of critically ill patients from mechanical ventilator among B.Sc. Nursing students at selected Nursing, Colleges Guwahati, Assam. Materials and Methods: Pre-experimental one group pre-test post-test design was adopted for the study. In this study, 50 B.Sc. nursing student of Sankar Madhab college of Nursing were selected by using non-probability one group pre-test post-test technique. The tools used for the study were demographic proforma, structured knowledge questionnaire and video on weaning of critically ill patient from mechanical ventilator. The analysis was done by using descriptive and inferential statistics in terms of frequency distribution, percentage, mean, standard deviation, paired ‘t’ test and chi-square. Results: The result shows that there was marked increase in post-test knowledge. In knowledge, the mean post-test score (18.4) was higher than mean pre-test knowledge score (10.7) and the mean difference between the pre-test and post-test score is 7.3. The calculated ‘t’ value was found to be 30.15. This indicates that the video assisted programme on weaning of critically ill patient from mechanical ventilator was effective in improving the knowledge of B.Sc. Nursing 4th year students. Conclusion: Present study concluded that the video assisted programme on weaning of critically ill patient from mechanical ventilator was effective in improving the knowledge of the B.Sc. Nursing 4^th year students.

INTRODUCTION:

Mechanical ventilator is often life-saving procedures, but constitutes an expensive treatment modality which is associated with iatrogenic complications such as ventilator-associated pneumonia (VAP) and ventilator-induced lung injury, which can lead to the development of the acute respiratory distress syndrome (ARDS) and increased mortality and morbidity.¹ The reasons for initiating MV are diverse. The most common reasons for initiation of MV are described as follows: pneumonia acute lung injury (33.2%), chronic obstructive pulmonary disease (9.7%), cardiogenic pulmonary edema (5.2%), neurological emergencies (16.9%), post-operative complications (24%) and cardiopulmonary arrest (11%).²

The time used versus time available for weaning ratio represents a new way of reporting the weaning status and process at an organizational level. Although various patient and systemic factors were linked to weaning activity, the most important factor was whether the intensive care unit nurse’s made use of time available.³ It showed that weaning frequently was given low priority despite being an essential part of care of the mechanically ventilated patients.⁴ It is vital for intensive care nurses to deliver high quality care to the critically ill patient using relevant technologies but also incorporating psychosocial care measures.⁵This balance is often one of the largest challenges facing by nurses in the intensive care environment. For this reason, intensive care nurses need to determine the unique interventions that will positively impact on the mechanically ventilated patient and assist in the patient’s progression toward desired outcomes.

OBJECTIVES:

The objectives of the study were:

1. To assess the pre-test knowledge regarding weaning of critically ill patients from mechanical ventilator among B.Sc. Nursing students at selected nursing colleges, Guwahati, Assam.

2. To assess the post-test knowledge regarding weaning of critically ill patients from mechanical ventilator among B.Sc. Nursing students at selected nursing colleges, Guwahati, Assam.

3. To determine the effect of video assisted programme on knowledge regarding weaning of critically ill patients from mechanical ventilator.

4. To find out the association between the pre-test knowledge score regarding weaning of critically ill patients from mechanical ventilator with selected demographic variables as age, duration of previous exposure to ICU, previous theory knowledge.

MATERIALS AND METHODS:

An evaluative research approach and a pre-experimental one group pre-test post-test design were used in the present study to accomplish the objectives. 50 numbers (fifty) of 4^th year B.Sc Nursing students studying in Sankar Madhab college of Nursing participated in the study. Ethical clearance certificate and formal permission was taken from the concerned authorities to conduct the research study. The tools used for the study were demographic proforma and structured knowledge questionnaire. The data obtained was analysed in terms of objectives of the study by using descriptive and inferential statistics. The software used for data analysis was Excel 2007.

With reference to the assessment of pre-test and post-test knowledge score on weaning of critically ill patients from ventilator presented in [Fig.1], the result indicates that in pre-test 29(45.31%) patients have inadequate knowledge, 35(54.69%) patients have moderate knowledge and none of them have adequate knowledge. Whereas in the post-test, 1(1.56%) patient have inadequate knowledge, 37(57.81%) have moderate knowledge and 26(40.63%) have adequate knowledge. So, post-test score remains higher than the pre-test knowledge score.

The data presented in table. 2 shows that the mean post-test knowledge score 18.4 was higher than the mean pre-test knowledge score 10.7 and the difference between pre-test and post- test was 7.3. The calculated t value was 30.15 and p value was .00001 at level of 0.01 significance. There is a significant difference between pre-test and post-test knowledge score on weaning of critically ill patient from mechanical ventilator. This indicates that the video assisted programme on weaning of critically ill patient from mechanical ventilator was effect in improving knowledge of B.Sc. Nursing 4^th year students.

Sakhardande, Veena D (2019) conducted a study on the effect of planned teaching program on knowledge regarding weaning of critically ill patients from mechanical ventilators among staff nurse working in critical care nursing of selected hospital in Pune city. In pre-test majority 12% samples had poor knowledge, 86% had average knowledge and 2% had good knowledge. Where as in post-test 100% had good knowledge. pre-test mean value was 13.5 and post-test mean value was 22.7 and there was no association between pre-test knowledge score and demographic variables.⁶

The present study findings that is presented in table 3 shows that there is no significant association between pre-test knowledge with selected demographic variables. The data also shows that the chi square value computed in pre-test knowledge with selected demographic variables were found to be not significant at <0.05.

Tejas P. (2018) conducted a study on effectiveness of planned teaching program on knowledge regarding care of care of patient with mechanical ventilator nursing students in selected nursing college at Gujarat state Findings revealed that pre-test knowledge mean score was 15.18(51.93%) and post-test mean score was 25.71(85.72%) and t-test value was 29.81 at the significance level 0.05 level df value was 59. Thus, findings shows that the planned teaching program was effective.⁷

CONCLUSION:

The findings of the study revealed that the total post-test knowledge score is significantly higher than the pre-test knowledge score. Thus, video assisted programme regarding weaning of critically ill patient from mechanical ventilators has an effect in enhancing knowledge among B.Sc. Nursing 4^th year students.
