Randomized Controlled Trial Multicenter StudyImpact of ibuprofen administration on renal drug clearance in the first weeks of life.
The administration of ibuprofen or any other nonselective cyclooxygenase (COX) inhibitor drug in early neonatal life is associated with a reduction of glomerular filtration, which reduces the elimination of drugs dependent on renal function for clearance. However, the relationship between COX inhibitor drug indication (prophylactic or therapeutic) and the magnitude of this effect remains unclear. ⋯ A significant and clinically relevant reduction in drug clearance is observed when ibuprofen is coadministered independent of indication, postmenstrual or postnatal age. Population modeling with covariate analyses can provide us with the tools to further disentangle the impact of nonselective COX-inhibitors on renal drug clearance.

Controlled Clinical TrialThe effect of propofol as an antioxidant agent in intravenous regional anesthesia.
Intravenous regional anesthesia (IVRA) is a technique whereby a tourniquet is used to restrict blood flow to an exsanguinated limb. Propofol was shown to attenuate ischemia-reperfusion damage. We aimed to investigate the effect of low-dose propofol as an antioxidant in this process. ⋯ However, in Group P, serum levels of MDA after the release of the tourniquet periods were significantly lower than that before the release of the tourniquet (p < 0.05). The addition of propofol (20 mg) to lidocaine for IVRA inhibits MDA levels. We conclude that the addition of propofol to lidocaine can be considered as a useful antioxidant in this type of anesthesia.
