The effects of providing information and instilling reassurance on uncertainty in weaning from mechanical ventilation
Abstract:
Uncertainty is a feeling of a lack of confidence, insecurity in a threatening situation, and
unfamiliarity which often occurs in the patients being weaned from mechanical ventilation
because they feel insecure and lack confidence in breathing. A quasi-experimental pre-test–
post-test design was used to examine the levels of uncertainty before and at two hours after
weaning from mechanical ventilation. The design also aimed at determining the effects of
providing information and instilling reassurance on uncertainty in the patients being weaned
from mechanical ventilation. The sample included 40 patients admitted to the surgical
intensive care units and medical intensive care units at the Somdej Prapinklao Hospital,
(Naval Medical Department), Bangkok, and the Somdej Pranangchao Sirikit Hospital,
(Naval Medical Department), Chonburi Province. The subjects were selected purposively
and then assigned to the control group and the experimental group, each consisting of 20
patients. The control group received routine nursing care, whereas the experimental group
received information and instilling reassurance. The instruments used for intervention
consisted of providing information and instilling reassurance for weaning from mechanical
ventilation. In addition, the instruments for data collection were composed of a demographic
characteristics data form, the readiness for weaning assessment, and the uncertainty for
weaning assessment. The data were analyzed by using frequency distribution, percentage,
Chi-square, mean, standard deviation, paired t-test, and independent t-test.
The result from this study showed that before and at two hours after weaning from
mechanical ventilation, most patients in both groups had moderate uncertainty. The patients
who received the provided information and instilling reassurance had a lower mean score of
uncertainty after the intervention (p < .001). Also after the intervention, the patients who
received the provided information and instilling reassurance had a lower mean score of
uncertainty than that of the patients who received only routine nursing care
(p < .001).
The results suggest that nurses should provide information and instilling reassurance to
reduce the uncertainty of patients being weaned from mechanical ventilation
