Analysis of the effects of pulse high-volume hemofiltration on severe acute panceatitis / 中华急诊医学杂志

ABSTRACT

Objective To compare the effects of pulse high-volume hemofiltration (PHVHF) and continuous veno-venous hemofiltration (CVVH) on severe acute panceatitis (SAP). Method From January 2005 to December 2009, a total of 38 patients with SAP were randomly(random number) divided into PHVHF group ( n = 18)and CVVH group ( n = 20). After hemofiltration for 72 hours, clinical symptoms, APACHE Ⅱ score, biochemical changes and mortality were observed. The levels of TNF-α, IL-6, and IL-10 in plasma were assayed by using ELISA before and after treatment. The doses of dopamine used in shock patients were also observed. Measurement data were expressed in(-x) ± s, and t-test was used for comparison between two groups. Results In both groups ,symptoms were markedly improved after treatment. The APACHE Ⅱ score, serum amylase, creatinine, and white blood cell count were decreased ( P ＜ 0.05). Besides, hypoxemia and acidosis were corrected, and the PHVHF group was superior to the CVVH group especially in heart rate, breathing and APACHE Ⅱ score ( P ＜ 0. 05).The levels of TNF-α, IL-6 and IL-10 decreased in both groups ( P ＜ 0.05), and the PHVHF group was superior to the CVVH group ( P ＜ 0. 01 ). The doses of dopamine used in shock patients also decreased in both groups ( P ＜0. 01 ), and they decreased more in PHVHF group than in CVVH group ( P ＜ 0.05). The mortality was 11.1%in PHVHF group and 25 % in CVVH group. Conclusions PHVHF is obviously superior to CVVH in the treatment of SAP, and can serve as an important adjuvant therapy for SAP, stabilizing the hemodynamics and reducing the levels of pro-inflammatory factors and mortality.
