AB INTRODUCTION:Few scientific evidence has demonstrated the effects of respiratory physiotherapy in intubated children. The clearance maneuvers in mechanical ventilation in this population require further investigation.OBJECTIVES:Analyze and compare the hemodynamic effects, ventilation and respiratory mechanics of two techniques in intubated children with respiratory failure.METHOD:Eleven children with mean age of 28.42±15.42 month were randomized into two groups according to the technique used: (1) Bag Squeezing (BS; n=5) and (2) vibrocompression thoracic (VCT; n=6). All variables were studied before, immediately and 30, 60 and 120min after the maneuvers (p<.05).RESULTS:for both groups were found similar results, no significant differences. Heart rate and mean blood pressure presented higher in BS group in the post maneuver (p=.04, p=.43) compared with pre maneuver. The HR, ETCO2, plateau pressure and static compliance were also higher in the post-maneuver in VCT group. There was no significant difference in the other respiratory variables or respiratory mechanics. Significant negative correlation between Rst e Cst was observed in the BS at all the times evaluated (R=.97,p=.00;R=.89,p=.04;R=.75,p=.00) The same results were observed for VC and ETCO2 post maneuvers (R=.90,p=.03). In the VCT was found positive correlation between the Rst and the Pp before maneuver (R=.97,p=.01),30(R=.94,p=.00) and 120min post (R=.66,p=.00) and between VC and ETCO2. There was also a positive correlation between VC and ETCO2 immediately after maneuver (R=.82,p=.04) and 30 min post (R=.87,p=.02).CONCLUSION:Both techniques didn't present changes in hemodynamic and ventilatory responses, even in the respiratory mechanic.
