Clinical efficacy comparison of different replacement fluid for continuous hemofiltration in severe sepsis / 中国医师进修杂志

ABSTRACT

Objective To compare the clinical efficacy of three kinds of replacement fluid for continuous hemofiltration in severe sepsis,and to develop a more rational composition.Methods Fifty severe sepsis patients with continuous hemofiltration were divided into four groups randomly.The configuration of the replacement fluid in accordance with the random number table,randomly selected from four different formulationsgroup A (13 cases)Ports composition provided by Nanjing general hospital;group B (12 cases)Zhongshan hospital composition; group C (11 cases)an improved composition; group D (14 cases)an improved composition by Donghua hospital affiliated to SUN Yat-sen university.Blood electrolytes,blood gas analysis,renal function,blood glucose(highest and lowest serum glucose in treatment period),high sensitive C-reactive protein(hs-CRP) concentration,calcium concentration in filter were tested before and after every treatment period.Results The concentration of blood electrolytes during treatment had no significant change (P ＞ 0.05).Renal function were improved significantly after treatment among four groups (P ＜ 0.05).The level of hs-CRP decreased significantly after treatment (P ＜ 0.05) and there was no significant difference among four groups (P ＞ 0.05).The change of serum glucose during treatment was the smallest in group D than that in group A,B,C [(3.0 + 0.9) mmol/L vs.(11.2 + 2.0),(3.8 + 1.1),(5.5 +1.3) mmol/L](P ＜ 0.05).Calcium concentration in filter was the lowest in group D than that in group A,B,C [(1.5 + 0.5) mmol/L vs.(2.0 + 0.7),(2.3 + 0.5),(2.1 + 0.4) mmol/L] (P ＜ 0.05).The dosage of heparin was the least during treatment in group D than that in group A,B,C[(6.5 ± 2.8) U/(kg·h) vs.(8.9 ± 3.4),(7.9 ± 3.0),(8.7 ± 3.1) U/ (kg· h)] (P ＜ 0.05).Conclusions Improved composition by Donghua hospital affiliated to SUN Yat-sen university hospital compared to other compositions can better maintain a stable blood glucose levels,have a better anticoagulant effect,reducing the application of heparin,maintain a stable homeostasis.It is worthy of using in clinic.
