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.
