Abstract :
Background: To determine changes in pulse rate, arterial blood pressures, splanchnic and cerebral
oxygen saturation and arterial oxygen saturation during endotracheal suctioning in patients requiring
ventilation support in the Pediatric Intensive Care Unit.
Methods: This prospective study was performed between June 2014 and December 2014 with patients
requiring mechanical ventilation support in the Pediatric Intensive Care Unit. All patients underwent
superficial endotracheal suctioning. Patients’ cerebral oxygen saturation (rSO2), splanchnic oxygen
saturation (rBO2), arterial oxygen saturation (SaO2), and heart rate were recorded at the beginning of
preoxygenation, at the beginning of and at 5 and 10 sec during suctioning, and over 1 min following
suctioning. rSO2 and rBO2 levels were measured using a near infrared spectroscopy (NIRS) device.
Systolic, diastolic and mean arterial blood pressures were measured before and 60 sec after suctioning.
Fraction of inspired oxygen (FiO2) values were made up to 100% before suctioning, and
preoxygenation was performed for 10 sec. FiO2 values returned to basal levels at 80 sec.
Results: No statistically significant difference was observed in rSO2, rBO2, heart rate or arterial
oxygen saturation during and after suctioning. Statistically significant increases were determined in
systolic, diastolic and mean arterial blood pressures after suctioning. The most significant decrease in
rSO2 and rBO2 was observed at 30 sec, while the most significant decrease in arterial oxygen saturation
and the most significant increase in heart rate were observed at 40 sec. rSO2 and rBO2 decreased 10 sec
before SO2.
Conclusions: Standard endotracheal suctioning does not cause any deterioration in rSO2, rBO2, SO2 or
heart rate.
