Randomized Controlled TrialTitration of sevoflurane in elderly patients: blinded, randomized clinical trial, in non-cardiac surgery after beta-adrenergic blockade.
Monitoring depth of anesthesia via the processed electroencephalogram (EEG) has been found useful in reducing the amount of anesthetic drugs, optimizing wake-up times, and, in some studies, reducing awareness. Our goal was to determine if titrating sevoflurane as the maintenance anesthetic to a depth of anesthesia monitor (SEDLine™, Masimo, CA) would shorten time to extubation in elderly patients undergoing non-cardiac surgery while on beta-adrenergic blockade. This patient population was selected because the usual cardiovascular signs of inadequate general anesthesia may be masked by beta-blocker therapy. ⋯ Use of the SEDLine™ monitor's data to titrate sevoflurane did not improve the time to extubation or change short-term outcome of geriatric surgical patients receiving beta-adrenergic blockers. (ClinicalTrials.gov number, NCT00938782).

Randomized Controlled TrialImproved accuracy of cardiac output estimation by the partial CO2 rebreathing method.
This study investigated the accuracy of the NICO monitor equipped with the newer software. Additionally, the effects of the increased dead space produced by the NICO monitor on ventilatory settings were investigated. ⋯ This study demonstrated the improved performance of the NICO monitor with updated software. The performance of the NICO monitor with ver. 4.2 or later software is similar to CCO. However, the cardiac output measurement did not fulfill the criteria of interchangeability to the cardiac output measurement by bolus thermodilution. Updates to ver. 5.0 attenuated the effects of rebreathing introduced by the NICO monitor without compromising the accuracy of the cardiac output measurement.

Randomized Controlled Trial Comparative StudyComparison between a dorsal and a belt tactile display prototype for decoding physiological events in the operating room.
Vibrotactile display technology represents an innovative method to communicate vital information on patients from physiological monitoring devices to clinicians. The increasing number of sensors used in clinical practice has increased the amount of information required to be communicated, overwhelming the capacity of visual and auditory displays. The capacity to communicate could be increased with the use of a tactile display. In this study, we have compared a dorsal (DTD) and belt tactile (TB) display prototype in terms of learnability, error rate, and efficiency. ⋯ The communication of information on physiological parameters by tactile displays was easy to learn and accurate for both prototypes. The DTD was easier to learn and affected less by distraction. Further evaluation is required in a clinical setting with expert users to determine the clinical applicability of these prototypes.

Randomized Controlled TrialA randomized-controlled study of intrathecal versus epidural thoracic analgesia in patients undergoing abdominal cancer surgery.
We sought to determine the effectiveness of continuous intrathecal thoracic analgesia (ITA) in comparison with continuous epidural thoracic analgesia (ETA) for the management of postoperative pain after abdominal cancer surgery in a randomised controlled study. ⋯ ITA and ETA produced the same levels of analgesia, without relevant complications.

Randomized Controlled Trial Comparative StudyComparison of effects of rapid colloid loading before and after spinal anesthesia on maternal hemodynamics and neonatal outcomes in cesarean section.
The effects of colloid loading after spinal anesthesia on hemodynamics in parturients during cesarean section have not been fully understood. This study tested the hypothesis that colloid loading after spinal blockade can reduce hypotension compared with preloading, and affect neonatal outcomes. ⋯ Colloid loading after induction of spinal anesthesia was similarly effective in reducing hypo- tension compared with preloading in cesarean section.
