  • Comparative Study on Adaptive Support Ventilation and Synchronized Intermittent Mandatory Ventilation in Ventilation Weaning in Patients after Fast-Track Coronary Artery Bypass Grafting

    Objective To investigate whether the respiratory support weaning based on adaptive support ventilation ( ASV) could reduce the duration of mechanical ventilation in patients after fast-track coronary artery bypass grafting ( CABG) . Methods After CABG during the same fast-track general anesthesia, 46 patients were randomly assigned to an ASV group or a synchronized intermittent mandatory ventilation ( SIMV) group as control. The duration of mechanical ventilation, hemodynamic parameters, and airway pressures were recorded. Meanwhile, the variables and the number of the arterial blood gas were recorded. Results The duration of mechanical ventilation was shorter in the ASV group than that in the control group [ 196( 152-286) ] min vs. 253( 196-498) min, P lt;0. 05] . The duration of ICUstay was shorterin the ASV group than that in the control group [ ( 14. 5 ±0. 7) h vs. ( 16. 8 ±0. 4 ) h, P lt;0. 01] . Fewer arterial blood analyses were performed in the ASV group than those in the control group [ 5 ( 4-7) vs.7( 6-9) , P lt; 0. 05] . Conclusions A ventilation weaning protocol based on ASV is practicable. It may accelerate tracheal extubation, shorten the length of ICU stay, and simplify ventilation management in patients after fast-track CABG.
