Multicenter StudySevere and long-lasting complications of the nerve root and spinal cord after central neuraxial blockade.
Although rare, major complications after spinal and epidural anesthesia do occur. We report the complications after central neuraxial blockade occurring in 2000 in France. ⋯ These findings suggest the influence of underlying spinal conditions in these complications.

Comparative StudyThe validity of bispectral index values from a dislocated sensor: a comparison with values from a sensor located in the commercially recommended position.
The influence of sensor dislocation on bispectral index (BIS) values is not clear. We compared the BIS values obtained from dislocated sensors with those from the commercially recommended positions. ⋯ The results indicate that during induction of and emergence from general anesthesia, a dislocated BIS sensor may produce questionable BIS values.

Comparative StudyThe effect of albumin concentration on plasma sodium and chloride measurements in critically ill patients.
We tested the hypothesis that the difference between indirect and direct sodium assays would be related to the plasma albumin concentration. Further, we proposed that differences between indirect and direct chloride assays might be explained by interference from other plasma constituents, particularly bicarbonate, and possibly albumin. ⋯ The central laboratory and ICUs assays are analytically, statistically, and clinically different for both sodium and chloride. Unless taken into account, the differences could be large enough in hypoalbuminemic populations (such as critically ill patients) to affect clinical diagnosis and decision making.

Clinical TrialCo-injection of clonidine prolongs the anesthetic effect of lidocaine skin infiltration by a peripheral action.
The addition of clonidine to local anesthesia prolongs the local anesthetic action, but in humans, the contribution of a peripheral mechanism remains unclear. ⋯ Clonidine has a significant peripheral action in enhancing duration of local anesthesia on superficial co-infiltration with lidocaine.

Randomized Controlled TrialThe effect of epidural anesthesia with different concentrations of ropivacaine on sevoflurane requirements.
We evaluated sevoflurane requirements during combined general-epidural anesthesia with different concentration of ropivacaine. ⋯ Epidural anesthesia can decrease sevoflurane requirements to a larger extent when a higher concentration of ropivacaine was applied.
