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.

Comparative Study Clinical TrialPreoperative ultra short-term entropy predicts arterial blood pressure fluctuation during the induction of anesthesia.
In this study, we sought to determine whether the preoperative nonlinear index of heart rate variability, ultra short-term entropy (UsEn), could predict cardiovascular responses to the induction of general anesthesia. ⋯ UsEn could predict arterial blood pressure fluctuations during the induction of anesthesia.

Case ReportsAn intraatrial thrombus and pulmonary thromboembolism as a late complication of percutaneous vertebroplasty.
Although percutaneous vertebroplasty is a simple and generally safe method for the management of vertebral compression fractures, cement leakage outside the vertebral body is a potential source of serious complications. We report a patient who presented with dyspnea and edema five years after percutaneous vertebroplasty and underwent open-heart surgery. This case demonstrates an intraatrial thrombus and pulmonary thromboembolism caused by venous leakage of polymethylmethacrylate as a late complication of the procedure.
