Randomized Controlled Trial Multicenter Study Comparative Study
Safety of HES 130/0.4 (Voluven(R)) in patients with preoperative renal dysfunction undergoing abdominal aortic surgery: a prospective, randomized, controlled, parallel-group multicentre trial.
Patients with impaired renal function are at risk of developing renal dysfunction after abdominal aortic surgery. This study investigated the safety profile of a recent medium-molecular-weight hydroxyethyl starch (HES) preparation with a low molar substitution (HES 130/0.4) in this sensitive patient group. ⋯ As we found no drug-related adverse effects of hydroxyethyl starch on renal function, we conclude that the choice of the colloid had no impact on renal safety parameters and outcome in patients with decreased renal function undergoing elective abdominal aortic surgery.

Multicenter Study Comparative Study
Fibrinolysis or hypercoagulation during radical prostatectomy? An evaluation of thrombelastographic parameters and standard laboratory tests.
Radical prostatectomy is at high risk for intraoperative and postoperative bleeding due to surgical trauma, release of urokinase and tissue type plasminogen activator. We conducted this prospective, observational multi-centre study to assess the degree of systemic fibrinolysis or hypercoagulation in the perioperative period. We studied serial changes in standard laboratory values and in thrombelastographic (TEG; Haemoscope Corporation, Skokie, IL, USA) parameters including lysis at 30 and 60 min (LY-30, LY-60), alpha-angle (alpha) and maximum amplitude. ⋯ Neither standard coagulation parameters nor TEG values showed any significant activation of fibrinolysis or of hypercoagulation in the preoperative period. Nevertheless, hypercoagulation seems to have a substantial clinical impact as it has been shown that cardiovascular complications and pulmonary embolism were the most common causes of death after retropubic prostatectomy.

Randomized Controlled Trial Multicenter Study Comparative Study
HES 130/0.4 (Voluven) or human albumin in children younger than 2 yr undergoing non-cardiac surgery. A prospective, randomized, open label, multicentre trial.
For perioperative volume therapy in infants and young children, human albumin has frequently been the colloid of choice. Recently, HES 130/0.4 (6% hydroxyethyl starch, Voluven; Fresenius Kabi, Bad Homburg, Germany) was developed, which demonstrated improved pharmacokinetics and a favourable safety profile in adults compared with hydroxyethyl starch products with a less rapid metabolization. ⋯ Both HES 130/0.4 and human albumin 5% were effective for haemodynamic stabilization in non-cardiac surgery of young infants with no adverse impact on coagulation or other safety parameters in our study population.

Multicenter Study
Stable plasma concentrations of unbound ropivacaine during postoperative epidural infusion for 24-72 hours in children.
The aim of this open, non-controlled, multi-centre study was to evaluate the pharmacokinetics and safety of a 24-72 h continuous epidural ropivacaine infusion in children aged 1-9 yr. ⋯ Following a 24-72 h epidural infusion of ropivacaine 0.4 mg kg(-1) h(-1) in 1-9-yr-old children, the plasma concentrations of unbound ropivacaine were stable over time with no age-dependency.
