Patient awareness under minimal anesthesia may include the painful impulses of a nerve stimulator used for the monitoring of muscle relaxation. We present a case where discomfort from nerve stimulation was greater than that caused by the surgical incision or the endotracheal tube.

To evaluate different pressure transducers, available in the operating room for pressure measurements, interfaced with common monitoring equipment, for quantitation of the train of four (TOF) fade during clinical neuromuscular block (NMB). ⋯ Measuring quantitatively the TOF fade by TPS devices is an economically feasible method for determining the adequacy of recovery from clinical non-depolarizing NMB.

Tympanic temperature can be obtained instantaneously using an infrared emission detection (IRED) thermometer. Its accuracy has been documented in a variety of clinical settings, but its performance at low body temperatures is still unknown. In this study we evaluated its performance during coronary artery revascularization surgery in which mild hypothermic cardiopulmonary bypass (CPB) was used. ⋯ Infrared tympanic thermometry is a reliable, alternative method to measure tympanic temperature and may be useful to assess core temperature in both normothermic and mild hypothermic conditions.
