Abstract:
Objective:To explore the method of the blood return of continuous blood purification therapy for patients with heart failure.
Methods:A total of 69 patients with heart failure treated by continuous blood purification therapy in our ICU from January 2017 to January 2018 were randomly divided into experimental group (blood return with blood bag,35 patients) and the control group (blood return with machine,34 patients). The vital signs, clinical manifestations and hemodynamic indicators of each patient were collected during the blood return of the first CBP therapy, and the data were analyzed between the two groups.
Results:After blood return of the first CBP therapy, the exacerbation of New York Heart Association (NYHA) heart function grade, SpO2, CVP, HR of patients in the control group were 33.27% (11/31), 0.91 ± 0.06, (12.44 ± 1.43) cmH2O (1cmH2O=0.098 kPa), (118.17 ± 3.27) times per minute and those in the experimental group were 6.25% (2/32), 0.96±0.04, (8.98±1.36) cmH2O, (90.45 ± 3.35)times per minute, respectively. The difference was statistically significant between the two groups (χ2=3.786, t=2.861, -7.565, 3.792, P< 0.05). Subgroup analysis showed that for patients within 24 hours of CBP treatment, the exacerbation of NYHA heart function grade, SpO2, CVP, HR of the control group and the experimental group were respectively 76.92% (10/13), 0.86±0.01, (12.92±1.12) cmH2O, (111.38±2.96) times per minute and 8.33% (1/12), 0.94±0.01, (8.11±0.74) cmH2O, (90.34±1.32) times per minute, the difference was statistically significant (χ2 =9.345, t=-14.101, 2.894, 7.648, P < 0.05). For patients treated with CBP therapy over 24 hours, the difference of the exacerbation of NYHA heart function grade, SpO2, CVP, HR of the control group and the experimental group was not statistically significant (P>0.05).
Conclusions:In patients with heart failure treated with CBP, especially in those treated with CBP therapy within 24 hours, blood return with blood bag may avoid the recurrence of heart failure.
