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.

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.

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.

Case ReportsCoagulopathy after cardiopulmonary bypass in Jehovah's Witness patients: management of two cases using fractionated components and factor VIIa.
Changes in the Jehovah's Witness (JW) blood refusal policy now give members the personal choice to accept certain processed fractions of blood, such as factor concentrates and cryoprecipitate. ⋯ Processed blood fractions can be a valuable adjuvant to drugs when treating bleeding in JW patients.
