Abstract

Objective:To compare the effects of open tracheal suctioning (OS) plus intermittent mandatory ventilation (IMV) vs closed tracheal suctioning (CS) plus volume guarantee ventilation (VG) on changes in mean cerebral blood-flow velocity (CBFv) of ventilated very low birth weight (VLBW) infants.Study Design:A total of 75 normotensive, ventilated VLBW infants (with normal cranial ultrasounds) had monitoring of mean CBFv, PCO 2 and mean arterial blood pressure (MABP) before, during and after 220 tracheal suctioning sessions during the first week of life. Multiple linear regression analysis was used to determine the factor(s) influencing the magnitude of relative changes from baseline in mean CBFv after suctioning.Result:In all, 49 VLBW infants receiving IMV had monitoring during 124 OS sessions between July 2002 and May 2005; 26 VLBW infants receiving VG had monitoring during 96 CS sessions between January 2006 and July 2007. The average magnitude of relative changes in mean CBFv was significantly less with CSVG, and was associated with the magnitude of relative changes in PCO 2 and suctioning-ventilator group.Conclusion:The average magnitude of relative changes in mean CBFv was reduced in VLBW infants with CSVG vs OSIMV.
