Effect of a Video-assisted Program on Knowledge of Weaning Critically Ill Patients from Mechanical Ventilators among B.Sc. Nursing Students

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.

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.

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.

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.

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.
