COMPARISON OF RESPIRATORY OUTCOMES IN WEANING FROM MECHANICAL VENTILATION WITH TWO METHODS OF PRESSURE SUPPORT VENTILATION AND T PIECE WITHIN INTENSIVE CARE UNIT PATIENTS

Due to the lack of direct potential effects and physiological outcomes of each
method of weaning from ventilator, none of the weaning methods was recommended on the other. The
present study was carried out in order to compare the breathing outcomes of weaning from the ventilator
into two methods of ventilation with pressure support and T-piece in patients in the intensive care unit
of Urmia Imam Khomeini Educational-Treatment Center in 2017-18.
Materials & Methods: This descriptive analytical study After obtaining the Ethics License from the
Regional Ethics Committee at the University Research was carried out on 44 patients in the intensive
care unit which patients who were eligible to be considered in study, was chosen and were located the
number of 22 patients in Group A (weaning by pressure support ventilation) and 22 patients in Group B
(weanhng by T-piece method). Data collection were collected using the patients file, the demographic
questionnaire and the checklist of the assessment of the respiratory status. Data were analyzed using
SPSS software version 20 and descriptive statistics (mean and standard deviation) and analytical tests
including parametric tests (T test and ANOVA) and nonparametric (Mann-Whitney, Wilcoxon and
Friedman).
Results: There was a significant difference between the two weaning groups terms of the two criteria of
peak inspiratory pressure and arterial blood oxygen saturation (p<0.05). In other outcomes, there was
no significant difference between the two groups (P>0/05).
Conclusion: Despite the differences in the peak inspiratory pressure and oxygen saturation of arterial
blood between the two groups, there was no significant difference in terms of other weaning outcomes.
So doing supplementary studies in this context is recommended
