Comparative StudyPerformance of the cerebral state index during increasing levels of propofol anesthesia: a comparison with the bispectral index.
The cerebral state monitor is a new device to measure depth of anesthesia. In this study we compared the cerebral state monitor with the bispectral index (BIS) monitor during propofol anesthesia. ⋯ The overall performance of both monitors during propofol induction was similar. However, the different dynamic profiles of these monitors indicate that BIS may be a more useful index for evaluating intermediate anesthetic levels, whereas CSI may be better for evaluating deeper anesthetic levels.

Clinical TrialMinimum alveolar concentration of sevoflurane for laryngeal mask airway removal in anesthetized children.
In children, it is preferable to remove the laryngeal mask airway (LMA) when the patient is still anesthetized. We sought to determine the optimal minimum alveolar concentration of sevoflurane that would allow removal of the LMA in children without airway complications. ⋯ LMA removal may be accomplished without coughing, moving, or any other airway complication at 1.84% end-tidal sevoflurane concentration in 50% of anesthetized children.

Case ReportsUnrecognized contralateral intrapleural catheter: bilateral blockade may obscure detection of failed epidural catheterization.
Thoracic epidural analgesia has been widely used to reduce both postoperative and posttraumatic pain. We describe a case of inadvertent right-sided interpleural catheter placement and pneumothorax during attempted epidural catheter placement for left-sided rib fractures that went unrecognized because of bilateral blockade and adequate analgesia.

Hydroxyethyl starch, but not modified fluid gelatin, affects inflammatory response in a rat model of polymicrobial sepsis with capillary leakage.
Intravascular volume therapy is crucial in septic patients to improve tissue perfusion and maintain stable hemodynamics. Modified fluid gelatins (MFG) and medium weight hydroxyethyl starches (HES) are the most widely used synthetic colloids. Our aim in this study, performed in septic rats challenged by cecal ligation and puncture (CLP), was to investigate the effects of HES and MFG on pulmonary capillary leakage and to determine whether an antiinflammatory mechanism was involved. ⋯ HES may attenuate capillary leakage by modulating an inflammatory response, whereas an antiinflammatory mechanism was not involved in the effects of MFG on capillary leakage.
