TWITCHER: a device to stimulate thumb twitch response to ulnar nerve stimulation.
To design and fabricate a device to simulate evoked thumb adduction in response to ulnar nerve stimulation. ⋯ TWITCHER has been well received by participants in simulation exercises including the use of neuromuscular blocking drugs.

ReviewPulse oximetry monitoring and late postoperative hypoxemia on the general care floor.
Hypoxemia has long been recognized as a risk to patients in the operating room and postanesthesia care unit, and hemoglobin oxygen saturation (HbO2) monitoring with pulse oximetry has become a standard of care in these areas. There is growing evidence, however, suggesting that later postoperative hypoxemia also may play a role in organ dysfunction leading to morbidity and mortality. ⋯ In this environment, telemetric pulse oximetry monitoring may represent a cost-effective approach to maximizing quality of care while enhancing risk management. This review discusses late postoperative hypoxemia and identifies areas for further investigation.

Randomized Controlled Trial Clinical TrialCraniofacial electromyogram activation response: another indicator of anesthetic depth.
After finding that craniofacial EMG preceding a stimulus was a poor predictor of movement response to that stimulus, we evaluated an alternative relation between EMG and movement: the difference in anesthetic depth between the endpoint of EMG responsiveness to a stimulus and endpoint of movement responsiveness to that stimulus. We expressed this relation as the increment of isoflurane between the two endpoints. ⋯ Our results suggest that, given the circumstances of our study, an EMG activation response by a nonmoving patient indicates that the patient is at an anesthetic level close to that at which movement could occur. However, because the first EMG activation response may occur simultaneously with movement, the EMG activation response cannot be relied upon to always herald a move response before it occurs. Our results also suggest that EMG responsiveness to a test stimulus may be used to estimate the anesthetic depth of an individual patient.
