PURPOSE: The newly introduced erector spinae plane block (ESPB) has given anesthesiologists an alternative regional anesthetic technique for thoracic analgesia. Although ESPB and retrolaminar block (RLB) have similar puncture sites, no clinical study comparing ESPB and RLB has been reported. The aim of this study was to compare ESPB and RLB in terms of analgesic efficacy in the context of multimodal analgesia following breast surgery. METHODS: Fifty female patients undergoing breast surgery under general anesthesia were randomly allocated to receive either ultrasound-guided ESPB or RLB with 20 mL of 0...

PURPOSE: Body perception disturbance is a common symptom and may be one of the key targets of treatment intervention in complex regional pain syndrome (CRPS). As a comprehensive assessment tool of body perception in patients with CRPS, the Bath Body Perception Disturbance Scale (BPDS) was developed, and its adequate reliability and validity have been reported. However, there is no available Japanese version. Therefore, this study aimed to develop a Japanese version of BPDS (BPDS-J) and to investigate the validity of this scale in Japanese patients with CRPS...

PURPOSE: The aim of this study was to evaluate the effects of hydroxyethyl starch (HES) 130/0.4/9 compared to 5% albumin on renal and coagulation safety profiles, volume efficacy and glycocalyx degradation in major abdominal surgery. METHODS: The study was approved by the institutional ethics committee as a single center, open-labeled randomized trial. Fifty patients undergoing hepatic or pancreatic surgery were randomly assigned to the HES group (n = 25), who received HES 130/0...

PURPOSE: Although uniportal video-assisted thoracoscopic surgery (VATS) has been widely used, the associated postoperative pain is still severe. Currently, a variety of regional anesthesia methods have been used to relieve postoperative pain. In our study, we wanted to evaluate the effectiveness of ultrasound-guided erector spinae plane block (ESPB) as a postoperative analgesia after uniportal VATS. METHODS: Eighty patients scheduled to undergo uniportal VATS were randomly divided into Group ESP and Group C...

PURPOSE: The effect of hyperglycemia on acute kidney injury (AKI) in patients undergoing cardiac surgery is unclear and may involve as yet unexplored factors. We hypothesized differential effects of intraoperative hyperglycemia on AKI after cardiac surgery depending on baseline inflammatory status, as reflected by the C-reactive protein (CRP) level. METHODS: This retrospective study included patients who underwent cardiac surgery seen at our hospital from 2008 to 2018...

The coronavirus disease (COVID-19) pandemic has brought critical challenges to anesthesiologists and perioperative practice. Whereas anesthesiologists may be primarily concerned with airway and respiratory management, the COVID-19 data accumulated to date indicate that primary and/or secondary cardiovascular complications are common. Previous studies have demonstrated that the mortality rate is significantly higher in patients with cardiovascular disease (CVD) than in patients without CVD. Dysregulation of immune function in patients with CVD may be involved in the prognosis of COVID-19 patients...

A substantial proportion of patients with coronavirus disease 19 (COVID-19) develop severe respiratory failure. Although the exact pathophysiology of severe COVID-19 pneumonia remains unknown and the characteristics of these patients are heterogeneous, the acute respiratory failure often fulfills criteria for acute respiratory distress syndrome (ARDS) and the clinical characteristics are also consistent with what is previously known about ARDS. Cohort studies also report distinctively high association between perioperative COVID-19 and postoperative mortality...

PURPOSE: The dynamic response of pressure monitoring circuits must be evaluated to obtain true invasive blood pressure values. Since Gardner's recommendations in 1981, the natural frequency and the damping coefficient have become standard parameters for anesthesiologists. In 2006, we published a new dynamic response evaluation method (step response analysis) that can plot frequency spectrum curves instantly in clinical situations. We also described the possibility of the defect of the standard parameters...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease [coronavirus disease 2019 (COVID-19) infection] first appeared in December 2019 in China and is now spreading worldwide. Because SARS-CoV-2 can be transmitted via aerosols and surface contaminations of the environment, appropriate use of anesthesia machines and appropriate behavior in the operation room (OR) are required specifically in relation to this disease. The use of high-performance hydrophobic filters with a high rate of virus rejection is recommended as the type of viral filter, and surgical team behaviors that result in aerosol splashes should be avoided...

PURPOSE: Volatile anesthetics (VAs) protect myocardial cells in cardiovascular surgery. A recent clinical trial of cardiopulmonary bypass (CPB) surgery reported no significant difference in mortality rates between the use of VAs and total intravenous anesthetics at 1 year postoperatively. However, oxygenator function may affect the VA pharmacokinetics. Thus, we measured the VA blood concentrations during CPB in patients managed with four different microporous polypropylene hollow fiber membrane oxygenators...

Anesthesiologists and intensivists are modern-day professionals who provide appropriate respiratory care, vital for patient survival. Recently, anesthesiologists have increasingly focused their attention on the type of spontaneous breathing made by non-intubated patients with pulmonary disease cared for in an intensive care unit, and also patients with chronic pain receiving cognitive behavioral therapy. Prior to our modern understanding of respiratory physiology, Zen meditators recognized that breathing has a significant impact on a person's mental state and general physical well-being...

Even though several studies have demonstrated the effectiveness of opioid free anesthesia (OFA) strategies in pediatric patients, OFA has not been studied in pediatric renal surgery. We, therefore, conducted a prospective observational pilot study on a total of 26 children to assess the feasibility and efficacy of using a single injection ultrasound-guided paravertebral block (PVB) at T10 level with 0.4 mL/kg bupivacaine 0.25% in combination with sevoflurane as an OFA technique in elective open renal surgery...

PURPOSE: The development of a preoperative anesthesia clinic (PAC) can reduce the number of surgical cases canceled on the day of surgery. However, there are only a few studies on the details of cancellations in the operating room. This study aimed to assess the incidence and reasons for surgical cases canceled from admission to the operating room to the start of surgery. METHODS: This retrospective study involved patients who underwent anesthesia performed by anesthesiologists between January 2008 and March 2019...

PURPOSE: We aimed to compare retrospectively the rates of renal morbidity and mortality in surgical patients receiving 6% HES 130/0.4 to those receiving albumin. METHODS: From a Japanese nationwide medical database between 2014 and 2016, we identified adults who received HES 130/0.4 (HES group) or albumin (albumin group) as a single colloid solution on the day of surgery. After propensity score matching, the two groups were analyzed with χ2 or Mann Whitney U test...

Coronavirus disease 2019 (COVID-19) has affected anesthetic care worldwide, including the provision of anesthesia for pediatric patients. Hospitals have balanced the risks associated with the potential surges of resource-intensive COVID-19 patients against the probable morbidity of delaying elective surgical procedures. These decisions are complicated by the unclear influence that COVID-19 has on the perioperative risk for disease-positive pediatric patients. We conducted a comprehensive literature search on MEDLINE for publications involving pediatric patients with COVID-19 who underwent general anesthesia...

Muscle relaxation induced by neuromuscular blocking agents (NMBAs) is necessary for tracheal intubation and immobilization during surgery. Although acetylcholinesterase inhibitors have been successfully used as antagonists for NMBAs, they have their limitations; their effects are transient and ineffective against profound neuromuscular blockade. In the past, alternative antagonists were developed, such as germine and 4-aminopyridine, which are effective for the treatment of diseases causing muscle weakness and could potentially be used as antagonists for NMBAs...
