Haemodynamic variations during independent lung ventilation in paediatrics

Independent lung ventilation (ILV) has been suggested in order to reduce volutrauma and barotrauma in the treatment of lung pathology with unilateral prevalence. The application of different PEEP levels to each lung can allow an increase in gas exange and reduce haemodynamic variations connected with high transpulmonary pressure. Application of synchronized ILV with ZEEP or 5 cm H2O PEEP did not in itself cause haemodynamic changes any different from those that occur with intermittent positive pressure ventilation (IPPV) and continuous positive pressure ventilation (CPPV) with 5 cm H2O of positive end-espiratory pressure (PEEP). Maintaining 5 cm H2O of PEEP in the less affected lung and increasing progressively PEEP from 5 to 15 cm H2O in the more pathologic lung, central venous pressure (CVP), cardiac rate and mean arterial pressure (MAP) remained stable. The application of progressive PEEP levels in the less damaged lung while maintaining a stable value in the more damaged lung showed an increase in CVP and cardiac rate and reduction in MAP: Applying synchronised ILV (sILV) an improvement in PaO2 was noted compared to volume controlled ventilation with 10 cm H2O of PEEP. The improvement in PaO2 appears more evident when the "best" PEEP for each lung has been applied.
