Abstract
Bacground: In general, patients treated in the Intensive Care Unit (ICU) require the installation of endotracheal tubes (ETT) and ventilators. Suction is an intervention to prevent airway obstruction and maintain airway patency. ETT suction caused haemodynamic problems in critically ill patients if the procedure is not appropriate, including pressure regulation and duration of suction.
Objective:The purpose of this study was to determine the effect of negative suction pressure on hemodynamic indices of patients.
Methods:This study is a pre-experimental study with a cross-over design involving 40 respondents (n = 40) taken by consecutive sampling technique. Data collection was using patient observation sheets, medical records, and treatment records. Inclusion criteria were adult patients ≥15 years old, using ETT and ventilator and patients with a diagnosis of pneumonia and incomplete observation were study exclusions. Statistical analysis using paired and independent t-test with a significance of 5%.
Results: The paired t-test showed a significant diffrence in the mean of SpO2, RR, HR and MAP, before and after suction with p value < 0.05. There was no significant difference between negative pressure suction of 20 kPA and 25 kPA (duration of suction 7 to 10 seconds) on all hemodynamic indicators of patients (SpO2, RR, HR, and MAP), p >0.05.
Discussion and Conclusions: Both of these pressures are safe to use in open ETT suction, because the increase in hemodynamics is within the safe limits, however suction must be carried out according to procedure and monitored properly.
