Randomized Controlled Trial
Dexmedetomidine in anesthesia of children submitted to videolaparoscopic appendectomy: a double-blind, randomized and placebo-controlled study.
To evaluate the hemodynamic responses to nociceptive stimuli in children submitted to videolaparoscopic appendectomy under balanced anesthesia with isoflurane and dexmedetomidine. ⋯ Dexmedetomidine combined with inhaled isoflurane for anesthesia of children submitted to videolaparoscopic appendectomy, efficiently blocks the hemodynamic responses to nociceptive stimuli. When compared to placebo, the use of dexmedetomidine did not change the need for supplemental doses of fentanyl for maintenance of hemodynamic parameters during the intraoperative period.

Evaluate the factors influencing blood glucose control of type 2 diabetic patients attended at a tertiary health care center. ⋯ A small part of the sample simultaneously achieved the goals for blood glucose, lipids and blood pressure control. Some factors, such as age and gender can be determinants to achieve control of diabetes. Greater efforts are still needed to achieve the goals for treatment in type 2 diabetic patients.

Comparative Study
[Doppler of the umbilical and fetal middle cerebral arteries after magnesium sulfate in preeclampsia].
To compare the ratio between the fetal middle cerebral artery and the umbilical artery using Doppler flow velocimetry indices (resistance index, pulsatility index and A/B relation) before and after administration of magnesium sulfate to pregnant women with severe preeclampsia (pure or superimposed). ⋯ Intravenous administration of magnesium sulfate in patients with severe preeclampsia is associated with increased frequency of fetal Doppler diagnosis of reduced resistance in the middle cerebral artery.

To evaluate patients admitted with near miss maternal mortality criteria to an Obstetric ICU. ⋯ Patients classified as near miss maternal mortality constitute an important group admitted to an Obstetric ICU. Better information about these patients is fundamental to improve care and prevent maternal mortality.
