To compare the effects of conventional ultrafiltration and modified ultrafiltration in protecting patients' pulmonary function during cardiopulmonary bypass.Thirty infants patients (less than 7 kg) were divided into two groups: conventional ultrafiltration group (CUF, n = 15) and modified ultrafiltration group (MUF, n = 15). The volume of ultrafiltration, transfusion, hematocrit (HCT) before and after ultrafiltration, patients' respiration function (respiration index, A-aDO2, airway pressure), the time of mechanical ventilation and ICU in the two groups were respectively monitored.The transfusion in MUF group was significantly less than in CUF group (P0.01), and the volume of ultrafiltration in MUF group was significantly more than in CUF group (P0.01). The time of mechanical ventilation and ICU staying in MUF group were significantly shorter in MUF group than that in CUF group (P0.05). At 12 and 24 hours after operations, the A-aDO2 in MUF group was lower than that in CUF group (P0.05), and the respiratory index in MUF group was higher than that in CUF group (P0.05).The modified ultrafiltration can effectively improve pulmonary function after operations for low weight infants. |
