“Purpose of review

This review examines the literature on the ability of an epidural test dose to detect intravascular or intrathecal epidural catheter misplacement in the obstetric patient.

Recent findings

There is no consensus on the exact nature of the epidural selleck chemical test dose in obstetrics, as no single regimen has been proven to be completely effective as an epidural test dose. The administration of a test dose is especially important in patients who may require the administration

of a large dose of local anesthetic such as for an emergency cesarean section. However, the accidental administration of an intended epidural therapeutic dose during labor analgesia, in either the intravascular or the intrathecal space, is not completely safe.

Summary

Gentle aspiration followed by an appropriate test dose, in epidural anesthesia for cesarean section, and careful observation of the patients in epidural labor analgesia increase the likelihood that an incorrectly placed catheter will be detected and that a harmful reaction to local anesthetics will be avoided.”
“Silver polyhedron coated electrospun nylon 6 nanofibrous membranes were produced using a nonhazardous and green electroless process. The process employed sodium citrate as

a complexing and reducing agent at 80 degrees Liproxstatin-1 cell line C, without the need of any surfactant or hazardous chemicals. Selleckchem Galardin The novel nanofibrous membrane, produced under optimum conditions, demonstrated high infrared (IR) extinction and ultraviolet (UV) blocking and good water vapor permeability. It is expected to have wide potential application for thermal radiation shielding, UV blocking and IR camouflage. (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011″
“The work presented in this paper is concerned with the fundamental study of a damage detection principle in a reverberant medium, based on ambient acoustic noise correlation. The aim here is to theoretically investigate the sensitivity of the correlation of received signals

to a local defect. The acoustic reverberation in the medium is modeled by a random process and an empirical description of the defect behavior is deduced from its experimental characterization. A global parameter r, corresponding to the energy ratio between the change in the correlation function caused by the defect and the defect-free correlation, is defined and theoretically derived. It is shown to essentially depend on the reverberation properties of the medium and the relative positions of the noise source, the sensor(s) and the defect. The theoretical expression of r is experimentally validated in a particular 2D-case (metallic plate) and then used to define the detection range and the optimal placements of the sensors.
