Abstract:
Objective To evaluate the effectiveness of intratracheal tube suctioning by respiratory mechanics measurement.Methods The indexes of respiratory mechanics,including respiratory rate,expiratory tidal volume,% leak around the tube,dynamic respiratory compliance and mean airway resistance were measured just before and 20 minutes after intraendotracheal tube suction in mechanical ventilated children with respiratory failure.Results Fifty-two measurements was carried out in 11 patie nts.The mean values of respiratory risistance was (116.73±27.12)cmH2O/L.s before suctioning and (93.38±26.64)cmH2O/L.s after suctioning,with significant differrence(P＜0.01)；The mean values of % leak around the tacheal tube dereased from(18.12±4.12)% before suctioning to (8.71±3.76)% after suctioning (P＜0.05),The mean values of expiratory tidal valume was markedly increased from(7.31±2.12)ml/kg before suctioning to(5.72±1.2)ml/kg after suctioning(P＜0.01),The total respiraory rate markedly decreased after suctioning.Conclusion The respiratory mechanics measurement is very useful to evaluate the airway patient.The removal of secretions is crucial in respiratory managemet.
