Postoperative cognitive dysfunction after noncardiac surgery: effects of metabolic syndrome.
Vascular risk factors, including metabolic syndrome, are known to contribute to the development of cognitive dysfunction. We tested the hypothesis that patients with metabolic syndrome are more likely to develop cognitive dysfunction after noncardiac surgery. ⋯ The results indicate that cognitive functions were more profoundly impaired in patients with metabolic syndrome undergoing noncardiac surgery compared with their healthier counterparts.

Case ReportsTwo cases of massive pleural effusion noted only after induction of anesthesia in living donor liver transplantation.
Two adult patients who underwent living donor liver transplantation with acute accumulation of right-side pleural effusion are reported. The chest X-ray of patient 1 showed no specific finding 3 days before the operation, and patient 2 was known to have pleural effusion and underwent pigtail drainage before transplant. After anesthesia induction and insertion of central venous catheters, a portable chest radiograph was taken to confirm the positions of the central venous catheters and endotracheal tube. ⋯ Both were discharged from the hospital in stable condition. Our cases suggest that chest X-ray after induction of the anesthesia and before liver transplantation surgery is recommended. In addition to documenting the positions of the central venous catheters and endotracheal tube, a potential life-threatening pleural effusion requiring appropriate management may be detected.

Randomized Controlled Trial Comparative StudyDexmedetomidine: an alternative for epidural anesthesia in tension-free vaginal-tape surgery.
Anesthetic management of tension-free vaginal-tape (TVT) procedures is sometimes difficult to deal with, especially when surgeons request a cough test. Dexmedetomidine has unique sedative and analgesic properties while having minimal respiratory effects, making it suitable for perioperative use in monitored anesthesia care. We aimed to compare dexmedetomidine and epidural anesthesia in TVT patients. ⋯ Dexmedetomidine can be an alternative to epidural anesthesia in TVT procedure requiring cough test.

Randomized Controlled TrialEffects of maternal supplementary oxygen on the newborn for elective cesarean deliveries under spinal anesthesia.
The aim of this investigation was to determine whether supplementary oxygen provided by either nasal cannula or face mask versus room air might affect fetal oxygenation during elective cesarean section under spinal anesthesia by assessing maternal and neonatal regional cerebral oxygenation (rSO(2)) with a cerebral oximeter. ⋯ The effect of maternal supplementary oxygen on the newborn has been demonstrated by a cerebral oximeter monitor and supported by umbilical cord blood gas analysis and Apgar scores.

Clinical TrialOnset of rocuronium-induced neuromuscular block evaluated subjectively and accerelomyographically at the masseter muscle.
The main aim of this study was to compare the onset times of rocuronium evaluated subjectively and by acceleromyography at the masseter muscle (MM). ⋯ Subjective evaluation of contractions of the MM by an anesthesiologist's hand may be reliable to determine faster timing for safe tracheal intubation.
