Background: Anesthetic management of pheochromocytoma and paraganglioma with Fontan circulation is challenging for physicians, with attention to cardiovascular physiology.
Case Presentation: We performed anesthetic management for pheochromocytoma and paraganglioma in three patients with Fontan circulation. We maintained intraoperative central venous pressure at preoperative level under fluid infusion and administrating nitric oxide to decrease pulmonary arterial resistance.
Background: Hepatectomy for patients with Fontan circulation consists of high central venous pressure and low pulmonary vascular resistance, and is challenging for physicians.
Case Presentation: We performed anesthetic management for hepatectomy in three patients with Fontan circulation. Massive bleeding and transfusion as well as careful management were needed.
Background: Carbamoyl phosphate synthetase deficiency (CPS1D) is a urea-cycle disorder (UCD). We report successful perioperative management of pediatric living donor liver transplantation (LDLT) in a CPS1D patient.
Case Presentation: A 10-year-old female patient with CPS1D underwent LDLT.
Background: Postreperfusion syndrome (PRS) after portal vein reperfusion during liver transplantation (LT) has been reported to cause rapid hemodynamic changes and is associated with a prolonged postoperative hospital stay, renal failure, and increased mortality. Although there are some reports on risk factors for PRS in brain-dead donor LT, there are a few reports on those in living donor LT. Therefore, we retrospectively reviewed the factors associated with PRS to contribute to the anesthetic management so as to reduce PRS during living donor LT.

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.

This study was conducted to test our new radiation protective device (RPD) for anesthesiologists and TEE operators in SHD interventions. The RPD, which consists of a head side shield and a cradle shield, was mounted on a 0.

However, the role of GIRK channel activation in pain signaling remains unknown mainly due to the lack of potent and selective GIRK channel activators until recently. The present study was designed to determine the effects and mechanisms of ML297, a selective GIRK1/2 activator, on nociception in the spinal cord by using behavioral studies and whole-cell patch-clamp recordings from substantia gelatinosa (SG) neurons.

On the other hand, the anticoagulation factors in fresh frozen plasma can also deter the clotting ability. This study investigated the effect of fresh frozen plasma administration on the comprehensive clotting ability following cardiopulmonary bypass.

However, it is not clear whether there is an optimal systolic blood pressure (SBP) level after reperfusion for living-donor transplant outcomes. The aim of this study is to investigate the effect of SBP after reperfusion on early graft function in living-donor kidney transplantation.

CS patients are increasingly being treated with cardiac resynchronization therapy-defibrillators (CRT-Ds). For the first time, we report the anesthetic management of a CS patient with a CRT-D.

Case Presentation: A 45-year-old woman was admitted for local recurrence of pheochromocytoma complicated by intestinal pseudo-obstruction. The intestinal pseudo-obstruction showed poor response to α-adrenergic receptor blocker and she was scheduled for surgical resection of pheochromocytoma.
Background: Bleeding and carbon dioxide (CO) gas embolism have been reported as serious complications associated with laparoscopic surgery. We present a case of cerebral infarction presumably caused by CO gas embolism during laparoscopic hepatectomy.
Case Presentation: During liver resection, the end-tidal CO suddenly dropped from 40 to 21 mmHg.
Objectives: Seizure duration and morphology, postictal suppression, and sympathetic nervous system activation are all recommended as assessments of adequate seizure in electroconvulsive therapy (ECT). However, blood pressure and heart rate are not typically assessed as part of sympathetic nervous system activation because of the administration of anesthetic or cardiovascular agents during ECT. Although the pupils are known to reflect to the activity of autonomic nervous system and the degree of brain damage, previous studies have not examined the relationship between seizure of electroconvulsive therapy and pupillary response.

PEX with albumin replacement fluid reportedly decreases fibrinogen levels. However, no reports have described the effects of PEX with albumin replacement fluid on blood coagulation parameters and blood loss during the perioperative period.

A 27-year-old woman with Crohn's disease, who had sustained clinical remission for two years following treatment with mesalazine and nutrition therapy, was admitted to our hospital complaining of dry cough, mild dysphagia, and slight fever. A computed tomography of the chest demonstrated an increase in the thickness of the tracheal wall. Bronchoscopy showed a diffusely erythematous and edematous mucosa with whitish granular lesions in the trachea and main carina.

Dominant mutations in the Serca2 gene, which encodes sarco(endo)plasmic reticulum calcium-ATPase, predispose mice to gastrointestinal epithelial carcinoma [1-4] and humans to Darier disease (DD) [14-17]. In this study, we generated mice harboring N-ethyl-N-nitrosourea (ENU)-induced allelic mutations in Serca2: three missense mutations and one nonsense mutation. Mice harboring these Serca2 mutations developed tumors that were categorized as either early onset squamous cell tumors (SCT), with development similar to null-type knockout mice [2,4] (aggressive form; M682, M814), or late onset tumors (mild form; M1049, M1162).

Ultiva® is not approved for epidural or intrathecal use in clinical practice. Previous studies have reported that Ultiva® provokes opioid-induced hyperalgesia by interacting with spinal dorsal horn neurons.
