Abstract:
Background of the study
Weaning from M is the process of gradually withdrawing artificial ventilation to the
intubated patients for short or long time in critical care setting.
Objective of the study
The objective of the study was to assessment the knowledge and practices of ICU
nurses regarding the weaning criteria from the ventilator in public hospitals in Sana'a –
Yemen
Research Methodology
A descriptive cross-sectional study was carried out at a public hospitals in Sana’a
City-Yemen among ICU nurses. The sample size was 93 Yemeni nurses. The sample
size was determined through used EpiCalc 2000. A stratified simple random sampling
was applied. Data were collected by using a close-ended questionnaire to testing
knowledge and observational checklist to testing nurses practice. A pilot study was
conducted and validity and reliability of the questionnaire was also tested. The data
were analyzed using SPSS and measured using frequency and percent for categorical
variables and Means and SD for quantitative variable. t-test was used to determine the
differences between two variables and one-way ANOVA determine the differences
between more than two variables. χ2-
test was used to determine the relationship
between categorical variables. A P-value <0.05 was considered statistically significant.
Approval from Al-Razi University was obtained and principles of hospitals and oral
consent was obtained from nurses to participate in the study.
Results
The results showed that (51.6%) of ICU nurses were male, (52.7%) were married
with mean ± SD, 29.7 ± 4.5 years old, (75.3%) had working experience from 1-5 years.
Two third (64.5%) of them had a diploma degree, (40.9%) had courses training in ICU
and (83.9%) of them had not received training program on the WC ftom MV. (54%) of
the nurses had correct knowledge toward WC from MV whereas (46%) of them had
incorrect knowledge. While (39%) of nurses had poor knowledge, and (50%) of them
had moderate knowledge and (11%) of them had good knowledge, While (46%) of the
nurses were correctly practiced to WC from MV, whereas (44%) of them were not
done and (10%) need correctly practiced. As regards to level of practice, (49%) had
poor practice, (36%) had a moderate practice and (15%) had a good practice. There
was no significant differences in the mean knowledge scores toward WC by
demographic characteristics of nurses (P>0.05).
A significant differences in the mean knowledge scores toward WC according to
diploma degree in respiratory therapy was found (P<0.05) but not for course training in
WC and courses training in ICU (P>0.05). A statistically significant differences was
found in mean practice scores toward WC from MV by demographic characteristics of
XVI
nurses (P<0.05) but not for sex (P>0.05). A statistically significant differences was
found in mean practice scores toward WC from MV by diploma degree in respiratory
therapy, course training in WC and courses training in ICU (P< 0.05).
Conclusion and Recommendations
This study conclude that (50%) of the nurses had moderate knowledge toward WC
from MV and (36%) of them had moderate practice, This study recommended
increasing knowledge and practice of ICU nurses through the courses training and
implementation WC and protocol weaning in all ICU units.
