We noted abdominal decompression improved hemodynamic status: pulse decreased, abdominal perfusion pressure increased (p < 0.0001), lactatemia decreased (p < 0.05); improved respiratory function: SpO2 increased (p < 0.0001), respiratory rate decreased in NCPAP group (p < 0.0001), inspiratory peak pressure decreased in mechanical ventilation group (p < 0.0001); improved renal function: uremia, cretininemia decreased (p < 0.0001); improved acidosis status: pH, HCO3 - increased (p < 0.05); and abdominal perimeter decreased (p < 0.0001).
