Abstract:
Aims: Endotracheal suctioning is the most effective way to clear discharge and maintain open airway. This is usually done by nurses. This study aimed to determine the effect of combinational changes of catheter size and its related suction negative pressure on hemodynamic parameters of patients undergoing mechanical ventilation.
Materials & Methods: In this clinical trial study, thirty-five patients undergoing ventilators were eligible for inclusion were selected by available sampling method. Endotracheal suctioning was performed for each patient ۴ times with at least ۲ hours interval by catheter ۱۰ and ۱۲ and negative pressures of ۱۰۰ and ۱۵۰ were used. Hemodynamic parameters of all patients were recorded immediately before, immediately after, ۱۰ and ۲۰ minutes after each intervention. The data were then analyzed using SPSS ۲۱ and ANOVA with repeated measures.
Findings: Suctioning with catheters ۱۰ and ۱۲ at pressures of ۱۰۰ and ۱۵۰ increased the hemodynamic parameters immediately after endotracheal suction. These increases was significant in systolic blood pressure (p=۰.۰۰۴) and mean arterial blood pressure (p=۰.۰۱). This test showed a statistically significant difference between intervention and intra-intervention in mean arterial oxygen saturation at post-suction time (p=۰.۰۰۱).
Conclusion: Although the catheter ۱۲ and pressure ۱۰۰ and ۱۵۰ indicated a greater increase in hemodynamic parameters at the time immediately after endotracheal suctioning, the changes are minor and within the normal range and decreased ۱۰ and ۲۰ minutes after the procedure and approached pre-suction time.
