Case ReportsSuccessful management of segmental zoster paresis on the upper arm with temporally burst spinal cord stimulation.
Segmental zoster paresis (SZP) of the limbs is characterized by a focal, asymmetric neurogenic weakness that may occur in an extremity affected by herpes zoster (HZ). In this case report, we describe the case of a patient with SZP who presented with these problems and responded well to temporary spinal cord stimulation (SCS) and systematic rehabilitation. A 62-year-old female patient was referred for right upper limb pain, weakness, and insomnia due to pain. ⋯ Furthermore, the grip strength of the right hands increased from 6.7 to 16.8 kg at discharge. We induced temporal SCS and rehabilitation of the right upper limb SZP and successfully reduced the pain. An in-depth understanding of the neurological complications secondary to HZ should be emphasized, with temporal SCS and rehabilitation expected to play a crucial role in the motor recovery of patients with SZP.

Observational StudyRisk factors of cardiac arrest and failure to achieve return of spontaneous circulation during anesthesia: a 20-year retrospective observational study from a tertiary care university hospital.
There is still a lack of robust data on the epidemiology of cardiac arrest during anesthesia. We investigated the frequency and risk factors of cardiac arrest during anesthesia over the past two decades at a tertiary care university hospital in Japan. ⋯ Blood loss was the most common cause of cardiac arrest and blood loss-induced cardiac arrest was independently associated with failure to achieve ROSC. Further improvements in treatment strategies for bleeding may reduce the future incidence of cardiac arrest and death during anesthesia.

Safe sedation management using volatile anesthetics during cardiopulmonary bypass.
Several pieces of evidence suggest that volatile anesthetics (VAs), which were originally used as sedatives, have myocardial protective effects against cardiac ischemia-reperfusion injury. In Europe and the United States, the use of VAs during cardiopulmonary bypass (CPB) is widespread, as 2019 European Association for Cardio-Thoracic Surgery (EACTS)/European Association of Cardiothoracic Anaesthesiology/European Board of Cardiovascular Perfusion, 2011 American College of Cardiology/American Heart Association, and 2017 EACTS guidelines recommend their use in cardiovascular surgery, based on their potential myocardial protective effects. ⋯ Therefore, it is important to be aware of the risks and possible adverse events associated with VA use during CPB to ensure safe sedation management. Herein, we describe in detail issues such as intraoperative awareness, air pollution, and damage to oxygenators due to VA use and propose precautions.

Neurological sedative indicators during general anesthesia with remimazolam.
The bispectral index (BIS) value during general anesthesia with the newly developed anesthetic remimazolam is reported to be relatively high; however, the reason for this and the appropriate indicator for assessing the sedation level during remimazolam anesthesia have not been determined. In this study, the level of sedation during general anesthesia with remimazolam was evaluated using several different indicators. ⋯ Processed electroencephalograms (BIS and PSI), and SEF of BIS® were relatively high during anesthesia with remimazolam, but SEF of Sedline® or pupillary diameter could be a supportive indicator to confirm sedation level during remimazolam anesthesia.
