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.
ObjectiveTo summarize perioperative management experience of 16 patients undergoing surgical correction of anomalous origin of the left coronary artery from pulmonary artery (ALCAPA). MethodsWe performed a retrospective analysis of 16 patients who received surgical correction of ALCAPA between January 2005 and December 2013 in Cardiovascular Center of Children's Hospital of Fudan University. There were 6 males and 10 females with their age ranging from 2 months to 13 years (mean age of 23.25±0.63 months) and body weight ranging from 5 to 30 kg (mean body weight of 19.77±0.75 kg). All the patients underwent direct implantation of the anomalous coronary artery into the ascending aorta, and received comprehensive management regarding left ventricular ejection fraction (LVEF), heart rate, blood pressure, arterial blood gas, urinary volume, blood lactic acid and central venous pressure. ResultsPostoperative complications were low cardiac output syndrome (LCOS) in 9 patients (including intractable LCOS in 2 patients) and arrhythmia in 1 patient. One patient with intractable LCOS and arrhythmia died postoperatively with the mortality of 6.25%. Cardiopulmonary bypass time was 85-260 (135.61±35.01) minutes, aortic cross-clamping time was 40-97 (57.32±16.02) minutes, mechanical ventilation time was 34-187 (106.34±41.62) hours, length of CICU stay was 2-21 (8.13±5.02) days, and hospital stay was 12-51 (22.14±5.00) days. Postoperative LVEF and left ventricular fractional shortening were significantly higher than preoperative values (P < 0.05). ConclusionKey points for successful surgical correction of ALCAPA include meticulous perioperative management, preoperative heart function improvement, prevention of postoperative complications and use of new techniques.
