Randomized, Controlled Trial Comparing Synchronized Intermittent Mandatory Ventilation and Synchronized Intermittent Mandatory Ventilation Plus Pressure Support in Preterm Infants
Pediatrics, 2006Co-Authors: Zenaida C. Reyes, Nelson Claure, Markus K. Tauscher, Carmen D'ugard, Silvia Vanbuskirk, Eduardo BancalariAbstract:BACKGROUND. Prolonged mechanical Ventilation is associated with lung injury in preterm infants. In these infants, weaning from synchronized Intermittent Mandatory Ventilation may be delayed by their inability to cope with increased respiratory loads. The addition of pressure support to synchronized Intermittent Mandatory Ventilation can offset these loads and may facilitate weaning. OBJECTIVE. The purpose of this work was to compare synchronized Intermittent Mandatory Ventilation and synchronized Intermittent Mandatory Ventilation plus pressure support in weaning from mechanical Ventilation and the duration of supplemental oxygen dependency in preterm infants with respiratory failure. METHODS. Preterm infants weighing 500 to 1000 g at birth who required mechanical Ventilation during the first postnatal week were randomly assigned to synchronized Intermittent Mandatory Ventilation or synchronized Intermittent Mandatory Ventilation plus pressure support. In both groups, weaning followed a set protocol during the first 28 days. Outcomes were assessed during the first 28 days and until discharge or death. RESULTS. There were 107 infants enrolled (53 synchronized Intermittent Mandatory Ventilation plus pressure support and 54 synchronized Intermittent Mandatory Ventilation). Demographic and perinatal data, mortality, and morbidity did not differ between groups. During the first 28 days, infants in the synchronized Intermittent Mandatory Ventilation plus pressure support group reached minimal ventilator settings and were extubated earlier than infants in the synchronized Intermittent Mandatory Ventilation group. Total duration of mechanical Ventilation, duration of oxygen dependency, and oxygen need at 36 weeks9 postmenstrual age alone or combined with death did not differ between groups. However, infants in synchronized Intermittent Mandatory Ventilation plus pressure support within the 700- to 1000-g birth weight strata had a shorter oxygen dependency. CONCLUSIONS. The results of this study suggest that the addition of pressure support as a supplement to synchronized Intermittent Mandatory Ventilation during the first 28 days may play a role in reducing the duration of mechanical Ventilation in extremely low birth-weight infants, and it may lead to a reduced oxygen dependency in the 700- to 1000-g birth weight strata.

effect of volume guarantee combined with assist control vs synchronized Intermittent Mandatory Ventilation
Journal of Perinatology, 2005Co-Authors: Kabir Abubakar, Martin KeszlerAbstract:To compare the effect of combining assist/control with volume-guarantee (AC+VG) vs synchronized Intermittent Mandatory Ventilation with VG (SIMV+VG) on tidal volume (VT), peak inspiratory pressure (PIP), mean airway pressure (MAP), respiratory rate, heart rate, oxygen saturation (SpO2), and minute volume (MV) in preterm infants. A total of 12 infants were randomized to receive AC+VG, followed by SIMV+VG, or the opposite sequence for four alternating 2-hour periods. Airway pressure of machine breaths was higher during SIMV. MV and VTe were similar, but more variable during synchronized Intermittent Mandatory Ventilation. The VTe of unsupported breaths during SIMV was lower than machine breaths of SIMV and AC. There was more tachycardia and tachypnea with a lower and more variable SpO2 during SIMV. SIMV+VG is associated with higher work of breathing indicated by tachycardia, tachypnea and lower SpO2 compared to AC+VG. VG appears to be more effective when combined with AC than with SIMV.
