RESUMO
Objective To investigate the relationship between Serum BNP and heart failure in patients un-dergoing maintenance peritoneal dialysis ( MPD) .Methods 80 uremia patients who underwent MPD and 40 healthy volunteers were enrolled in the study.In the morning of treatment, we assessed their cardiac function according to in-terrogation, physical examination, chest X-ray and echocardiography while detecting BNP, Scr, BUN levels in the fasting venous serum of upper extremity.Results 80 MPD patients were divided into 2 groups:a heart failure group (Group A, n=42) and a normal cardiac function group (Group B, n=38).40 healthy volunteers served as a con-trol group ( Group C ) .There were no significant differences in age, weight and sex ratio among 3 groups ( P>0.05).The time period of maintenance peritoneal dialysis in Group A and B was similar (P>0.05).Compared with Group C, the levels of Serum BNP, Scr and BUN were significantly higher in Group A and B( P0.05) .The level of Serum BNP was signifi-cantly higher in Group A than that in Group B (P<0.05).Conclusion The level of Serum BNP may be closely re-lated to the cardiac function and it may be used as a predictor for heart failure in MPD patients.
RESUMO
Objective To expolre the clinical characteristic of hospital acquired acute renal failure(HA-ARF).Methods To retrospectively analyse the clinical datas of 103 patients who were suffered from acute renal failure in the duration of hospital stay within 5 years,which was compared with the homeochronous community-acquired acute renal failure(CA-ARF).Results In the 103 cases of HA-ARF,the incidence rate was 32.04% in the major age range from 60 to 74 years old,infection was the most important factor(33.01%),then other factors were cardial and cerebrovascular diseases(17.48%),acute hypovolemia(14.56%) and operation(9.71%);The complicating other organ nonfunction(34.95%),and the mortality rate was 39.80%,all the factors in HA-ARF were higher than that in CA-ARF.Conclusion The main factors of origin in HA-ARF are infection,cardial and cerebrovascular disease,acute hypovolemia and operation.The mortality rate of this disease is higher.Etilogical treatment promptly and dialysis regimen are the main means to rescue these patients.
