Randomized Controlled Trial
[The effect of oral ondansetron in the prevention of postoperative nausea and vomiting].
Not so many years ago, the incidence of postoperative nausea and vomiting used to reach 40% to 50%. More recent publications indicate that this complication still reaches considerable frequency: 20 to 30%. The present study had the objective of evaluating the impact of oral administration of ondansetron on the incidence of postoperative nausea and vomiting among patients submitted to general anesthesia. ⋯ Ondansetron, 16 mg orally, administered before the operation significantly reduced the incidence of postoperative nausea and vomiting. The simplicity of administration and low cost of this presentation justify the choice of this administration route.

This report describes the clinical characteristics of children and adolescents bearers of oncological disease who were admitted to PICU with severe sepsis and septic shock. The predicting factors for mortality and for need of pulmonary mechanical ventilation were also determined. ⋯ This research suggests that early intensive treatment for children with cancer exhibiting severe sepsis and/or septic shock could be an important factor to influence the mortality rate of these patients. Moreover, that noninvasive ventilation could be an option to reduce endotracheal intubation and invasive ventilation.

Randomized Controlled Trial Clinical Trial
[Racemic bupivacaine, levobupi vacaine and ropivacaine in regional anesthesia for ophthalmology -- a comparative study].
Racemic bupivacaine, used in peribulbar anesthesia owing to its high potential to promote motor blockade, presents a smaller safety margin for cardiotoxicity in relation to ropivacaine and levobupivacaine. The objective of this study was to compare the degree of motor blockade and alteration of intraocular pressure (IOP) produced by racemic bupivacaine, levobupivacaine and ropivacaine in peribulbar block. ⋯ Considering the advanced age of most of these patients and the high concentrations of local anesthetics used in peribulbar blockade, the use of ropivacaine and levobupivacaine produces motor blockade as effective as racemic bupivacaine while minimising risks for cardiotoxicity.

To determine the profile of patients at the Hospital São Paulo with pressure ulcers (PU). ⋯ The study showed a high risk of PU development, indicating the importance of having knowledge about the main characteristics of the hospitalized patients who may develop pressure ulcers, and, thus, preventing them.

Ophidic accidents are a serious health problem for tropical countries, because are responsible for the high incidence of morbidity and mortality. ⋯ Accidents owing to poisonous snakes are frequent in the State of Goiás, the young male population is more often attacked and they are an important cause of death.
