Randomized Controlled Trial
Topical anaesthesia and intravenous cannulation success in paediatric patients: a randomized double-blind trial.
It is not known whether the choice of topical anaesthetic influences the likelihood of successful i.v. cannulation in the paediatric population. The null hypothesis of this study was that no difference exists in the initial success rate of cannulation between two commonly used topical anaesthetics. ⋯ No difference exists in the cannulation success rates between the two anaesthetics. The choice of topical anaesthetic in paediatric cannulation should be based on other factors such as cost, time to anaesthesia, efficacy of the agent, and adverse effect profile.

Comparative Study
Comparison of the novel hydroxyethylstarch 130/0.4 and hydroxyethylstarch 200/0.6 in brain-dead donor resuscitation on renal function after transplantation.
The renal effect of hydroxyethylstarch (HES) solutions remains controversial. We hypothesized that the use of HES with a mean molecular weight of 130 kDa would reduce renal dysfunctions in the recipients. Our study was aimed at comparing the effects of two fluid regimens (HES 130/0.4 or HES 200/0.6) used for the resuscitation of brain-dead donors on the rate of delayed graft function (DGF) and the serum creatinine levels post-transplantation. ⋯ Using a modern, third-generation, rapidly degradable HES preparation with a low degree of substitution seems to be associated with a better effect on the renal function of recipients.

Recent studies showed that hyperglycaemia (HG) blocks anaesthetic-induced preconditioning. The influence of HG on anaesthetic-induced postconditioning (post) has not yet been determined. We investigated whether sevoflurane (Sevo)-induced postconditioning is blocked by HG and whether the blockade could be reversed by inhibiting the mitochondrial permeability transition pore (mPTP) with cyclosporine A (CsA). ⋯ Sevoflurane-induced postconditioning is blocked by HG. Inhibition of the mPTP with CsA is able to reverse this loss of cardioprotection.
