Randomized Controlled Trial
[Assertiveness and peripheral intravenous catheters dwell time with ultrasonography-guided insertion in children and adolescents].
Randomized controlled trial which aimed to verify whether the use of vascular ultrasound (VUS) increases assertiveness in the use of peripheral venous catheter in children, and the catheter dwell time, when compared to traditional puncture. Data were collected after approval of theethical merit. Children and adolescents undergoing VUS-guided peripheral intravenous (GVUS) or puncture guided by clinical assessment of the venous conditions(CG) were included in the study. ⋯ Assertiveness was found in 73 (71.6%) GVUS catheters and in 84(71.8%) of the CG (p=0.970), and catheter dwell time presented a median of less than one day in both groups (p=0.121), showing nostatistically significant difference. VUS did not significantly influence the results of the dependent variables investigated. ClinicalTrials.govNCT00930254.

Randomized Controlled Trial
[Insulin infusion in intensive care: randomized controlled trial].
This randomized controlled trial compared the use of an intensive and conventional insulin protocol on clinical outcomes in patients with severe sepsis and septic shock, in the first 72 hours. It was conducted at a university hospital in the city of São Paulo. ⋯ A statistically significant (p<0.001) difference was observed in mean glycemia, but there was no difference in the variables of mean minimum arterial pressure (p=0.06) or maximum (p=0.11), serum creatinine (p=0,33) or in mortality (p=0.11). Although there was no difference between the groups regarding mortality, hemodynamic instability in the conventional group was longer and the only deaths occurred in it.
