The optimal colloid for renal protection during abdominal aortic aneurysm (AAA) surgery is not known. This study compared the effects of two hydroxyethyl starch (HES) solutions and gelatine on perioperative renal function. Sixty-two patients undergoing AAA surgery were randomized to 6 per cent HES of molecular weight 200/0.62 kDa or 130/0.4 kDa, or 4 per cent gelatine for plasma expansion. Measurements were taken of serum urea and creatinine to mark glomerular filtration, urinary immunoglobulin G : creatinine ratio to mark glomerular membrane function and alpha(1)-microglobulin : creatinine ratio to mark tubular dysfunction before, and for 5 days after, surgery. Serum urea was lower in both HES groups than the gelatine group. Serum creatinine was lower with HES 130/0.4 compared with gelatine at days 1, 2 and 5 after surgery (P = 0.020, P = 0.045 and P = 0.045 respectively). Urinary alpha(1)-microglobulin : creatinine ratio was lower with HES 200/0.62 compared with gelatine at 4 and 8 h (P < 0.050) and lower with HES 130/0.4 compared with gelatine at 4 to 24 h, and on days 4 and 5 (P < 0.050). Urinary immunoglobulin G : creatinine was lower in both HES groups compared with gelatine. There was no difference between the two starch groups. Compared with gelatine, volume expansion with both types of HES during AAA surgery improved renal function and reduced renal injury.

    • "Efforts were also made to determine the effect of 6% HES on renal function. However different indicators were used to test renal function, such as blood creatinine [32], glomerular filtration rate [30], the incidence of AKI based on different criteria [24,34,42] and RRT use2425262731,34,37,41,42]. The result need further confirmation because of the limitations of our included RCTs. "
    [Show abstract] [Hide abstract] ABSTRACT: Use of hydroxyethyl starch (HES) in septic patients is reported to increase the mortality and incidence of renal replacement therapy (RRT). However, whether or not use of HES would induce the same result in non-septic patients in the intensive care unit (ICU) remains unclear. The objective of this meta-analysis was to evaluate 6% HES versus other fluids for non-septic ICU patients. Randomized controlled trials (RCTs) were searched from Pubmed, OvidSP, Embase database and Cochrane Library, published before November, 2013. A meta-analysis was made on the effect of 6% HES versus other fluids for non-septic ICU patients, including mortality, RRT incidence, bleeding volume, red blood cell (RBC) transfusion and fluid application for non-septic patients in ICU. Twenty-two RCTs were included, involving 6,064 non-septic ICU patients. Compared with the other fluids, 6% HES was not associated with decreased overall mortality (RR = 1.03, 95%CI: 0.09 to 1.17; P = 0.67; I (2) = 0). There was no significant difference in RRT incidence, bleeding volume and red blood cell transfusion between 6% HES group and the other fluid groups. However, patients in HES group received less total intravenous fluids than those receiving crystalloids during the first day in ICU (SMD = -0.84; 95%CI: -1.39 to -0.30; P = 0.003, I (2) = 74 %). This meta-analysis found no increased mortality, RRT incidence, bleeding volumes or RBC transfusion in non-septic ICU patients, but the sample sizes were small and the studies generally were of poor quality.

    • "Also, in previous studies, in cardiac and aortic surgery patients with or without renal dysfunction, HES 6% 130/0.4 showed no increase in serum creatinine values or increased incidence of RRT [22, 23]. However, a recent study showed that gelatin impairs renal function more than HES 130/0.4 "
    [Show abstract] [Hide abstract] ABSTRACT: The addition of 6% hydroxyethyl starch (HES) into Ringer lactate priming solution may have adverse effects on hemostasis in patients undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) with or without the use of tranexamic acid. In a prospective, randomized clinical trial, 132 patients were assigned to receive 20 ml/kg of Ringer priming solution with or without tranexamic acid (TA) (Group RS-TA, n=34 and Group RS-noTA, n=32) or 10 ml/kg of 6% HES plus 10 ml/kg of RS priming solution with or without intravenous tranexamic acid (Group HES-TA, n=35 and Group HES-noTA, n=31). Estimated blood loss, chest tube drainage, amount of blood products, hemoglobin, hematocrit, platelet and coagulation parameters were examined before and 24 hour after surgery. For Group HES with tranexamic acid, when compared to other groups, estimated blood loss, postoperative 24 hour drainage loss and blood product transfusions were less (P=0.023; P=0.003; P=0.001; respectively) and hemoglobin, hematocrit values at 12 and 24 hours after surgery increased in comparison to other groups (P=0.041, P=0.034, P=0.004, P=0.001; respectively). Platelet concentrations were similar between groups (P>0.05). In CABG, the administration of tranexamic acid in HES 130/0.4 prime solution study group decreased estimated blood loss and chest tube drainage in comparison to patients receving Ringer prime solution with or without tranexamic acid postoperatively however, no effects on renal functions or postoperative complications were shown.

    • "A contrario, plusieurs études ont trouvé une absence de différence de retentissement sur la fonction rénale, entre les différents types de solutés (HEA de dernière génération 130/ 0,4 vs gélatine fluide modifiée vs albumine diluée), pour des volumes inférieurs à 33 mL/kg utilisés en période peropératoire et postopératoire immédiate (premier jour). Dans une étude randomisée [17], réalisée en chirurgie de l'anévrysme de l'aorte, la fonction rénale moyenne des patients, normale en préopératoire, s'altérait moins avec l'emploi d'un HEA 200/0,6 ou d'un HEA 130/0,4 qu'avec une gélatine. Deux études randomisées, mais à petits effectifs (n = 40 et 65) ont évalué, chez des opérés à fonction rénale préopératoire altérée, l'effet sur la fonction rénale des HEA 130/0,4 (vs. "
