Propofol reduces the amplitude of transcranial electrical motor-evoked potential without affecting spinal motor neurons: a prospective, single-arm, interventional study.
Propofol inhibits the amplitudes of transcranial electrical motor-evoked potentials (TCE-MEP) in a dose-dependent manner. However, the mechanisms of this effect remain unknown. Hence, we investigated the spinal mechanisms of the inhibitory effect of propofol on TCE-MEP amplitudes by evaluating evoked electromyograms (H-reflex and F-wave) under general anesthesia. ⋯ Propofol did not affect the amplitudes of the H-reflex and the F-wave, whereas TCE-MEP amplitudes were reduced at higher propofol concentrations. These results suggested that propofol can suppress the TCE-MEP amplitude by inhibiting the supraspinal motor pathways more strongly than the excitability of the motor neurons in the spinal cord.

Translation and validation of the Japanese Version of the Quality of Recovery-15 Questionnaire.
Patient-reported outcomes after surgery and anaesthesia have recently attracted attention. A recent systematic review and a consensus guideline recommend that patients' recovery can be adequately measured using the quality of recovery-15 (QoR-15) during the perioperative period; however, the Japanese version of the QoR-15 (QoR-15J) is not available. We aimed to translate the QoR-15 into Japanese and assess its validity. ⋯ QoR-15 was translated into Japanese and the Japanese version's validity was assessed in patients undergoing various types of surgery under general anaesthesia. Our results suggest that QoR-15J is feasible, reliable, valid, and responsive.

Ionized magnesium (iMg) is considered to be the biologically active fraction of circulating total serum Mg (tMg). However, only the relationship between tMg and postoperative shivering has been studied. To our knowledge, hitherto no clinical studies have investigated the association between serum ionized magnesium concentration ([iMg]) and postoperative shivering. Therefore, we aimed to retrospectively examine this association, focusing on hypomagnesemia and depletion of [iMg]. ⋯ A decrease in the [iMg] during surgery was significantly associated with postoperative shivering. Subjects who had an [iMg] lower than 0.6 mmol/L post-surgery and decreased [iMg] during surgery had a significantly higher risk of postoperative shivering. Intraoperative depletion of [iMg] was significantly associated with shivering.
