BACKGROUND: Hypotension after induction of general anesthesia (GAIH) is common in anesthesiology practice and can impact outcomes. METHODS: In this prospective multicenter, cross-sectional, observational study, the hypotension was defined as a decrease in mean arterial pressure of > 30% compared to the first measurement in the operation theatre before general anesthesia (GA) induction. Blood pressure was measured immediately at the time of endotracheal intubation (TETI ), at five (T5 ) and 10 (T10 ) minutes after...

PURPOSE: The aim of this study was to compare the force exerted by a three-dimensional (3D) printed modified supraglottic airway (mSGA) vs. that exerted by the i-gel on a 3D printed airway model. METHODS: After a preliminary experiment in Thiel embalmed cadavers, we created a 3D printed mSGA and five 3D printed airway models based on computed tomography data from five female Japanese patients. We compared the force exerted by the i-gel and mSGA on the larynx of the 3D printed airway models...

PURPOSE: Malignant hyperthermia (MH) is an inherited muscle disorder caused by abnormal elevations of intracellular calcium (Ca2+ ) in skeletal muscle. There are several reports of myotoxicity caused by local anesthetics, and the increased intracellular Ca2+ is considered to be an important cause. However, there is insufficient evidence regarding myotoxicity in MH-susceptible individuals when large doses of local anesthetics are administered. This study investigated the effect of MH predisposition on myotoxicity...

PURPOSE: Patients undergoing laparoscopic gynecological surgery are susceptible to postoperative nausea and vomiting (PONV). We hypothesized that a combination of epidural and general anesthesia to minimize intraoperative opioid administration would reduce the incidence of PONV following laparoscopic gynecological surgery. METHODS: Women undergoing elective laparoscopic gynecological surgery were randomly assigned to receive general anesthesia alone (group G, n = 45) or general anesthesia with epidural anesthesia (group GE, n = 45)...

PURPOSE: To comparatively examine in-hospital mortality among different underweight body mass index (BMI) categories in pancreatic cancer patients after pancreatectomy in Japan. METHODS: We conducted a large-scale multi-center retrospective cohort study of adult patients with pancreatic cancer who underwent pancreatectomy between April 1, 2010 and March 31, 2016. Patients were classified according to BMI as follows: normal BMI (18.50-24.99 kg/m2 ), mild thinness (17...

May-Hegglin anomaly (MHA) is an inherited autosomal dominant disorder characterized by giant platelets and inclusion bodies in granulocytes, and thrombocytopenia. There is no consensus on the perioperative management of this disorder. We report a case involving a patient with MHA who was perioperatively managed without platelet transfusion for cervical laminectomy and laminoplasty. In our case, the platelet count was measured to be 0.6 × 104 /µL using an automatic blood cell counter. Peripheral blood smear and genetic test analyses were performed, leading to a definitive diagnosis of MHA...

BACKGROUND: Both anesthetic-induced and ischemic preconditioning are protective against hepatic ischemia-reperfusion injury. However, the effects of these preventive methods on the metabolic function remain to be elucidated. We investigated the anesthetic conditioning and ischemic preconditioning on the metabolic function of the rabbit model of hepatic ischemia-reperfusion. METHODS: After approval by the institutional animal care and use committee, 36 Japanese White rabbits underwent partial hepatic ischemia for 90 min either under sevoflurane or propofol anesthesia...

This study was designed to examine deviation of the bronchus by postural change from supine to lateral position during spontaneous respiration. Fifteen healthy volunteers [13 men and 2 women, mean age: 34 years (range 26-42)] participated. Chest radiograms (anterior-posterior) were acquired in the order of supine, left lateral, and right lateral position. The bilateral bronchus angles and secondary carina angles were measured in the acquired images, and the angles were compared between the supine and lateral positions to evaluate deviation of the bronchus in the lateral position...

Analgesia and temporary inhibition of motor activity without interfering with central nervous function have been the essential merits of local anesthesia. Local anesthetics originated from cocaine have played a major role in local analgesia. However, the relatively short duration of action of local anesthetics has been a concern in intra- and post-operative analgesia. From the early age of modern local anesthesia, physicians and medical scientists had been struggling to control the active duration of local anesthetics...

PURPOSE: The impact of preoperative functional status on 30-day unplanned postoperative intubation and clinical outcomes among patients who underwent cervical spine surgery is not well-described. We hypothesized that functional dependence is associated with 30-day unplanned postoperative intubation and that among the reintubated cohort, functional dependence is associated with adverse postoperative clinical outcomes after cervical spine surgery. METHODS: Utilizing the 2007-2016 American College of Surgeons National Surgical Quality Improvement Program database, we identified adult elective anterior and posterior cervical spine surgery patients by Current Procedural Terminology codes...

PURPOSE: Spinal anesthesia (SA) is being increasingly used in infants to avoid the potential negative neurocognitive effects of general anesthesia (GA). However, SA has been reported to provide a relatively short duration of surgical anesthesia. METHODS: We retrospectively reviewed SA cases for surgical procedures lasting more than 60 min in children up to 3 years old. All patients received bupivacaine 0.5% (1 mg/kg up to 7 mg) with clonidine 1 µg/kg ± epinephrine...
