The patient state index (PSI) is a parameter of a four-channel electroencephalography (EEG)-derived variable used to assess the depth of anesthesia. A PSI value of 25–50 indicates adequate state of hypnosis, a...
Amniotic fluid embolism (AFE) is a life-threatening obstetric emergency. Because the maternal mortality associated with AFE is very high, early recognition and prompt treatment are important for improving the ...
Sodium-channel myotonia (SCM) is a nondystrophic myotonia, characterized by pure myotonia without muscle weakness or paramyotonia. The prevalence of skeletal muscle channelopathies is approximately 1 in 100,00...
Modified electroconvulsive therapy (m-ECT) is utilized worldwide as an effective treatment for drug-resistant psychiatric disorders. However, during m-ECT, treatment of hypotension and hypertension in response...
Wilson’s disease is a rare autosomal recessive disorder affecting copper metabolism, which presents liver and brain dysfunction caused by abnormal copper accumulation. We report a patient who showed exacerbati...
5-Aminolevulinic acid (5-ALA) is utilized for photodynamic diagnosis-assisted (PDD) surgery. However, it has been associated with vasodilation, hence, occasional hypotension.
Information on epidemiology of prolonged mechanical ventilation (PMV) patients in the acute care setting in Japan is totally lacking. We aimed to investigate clinical features, impact, and long-term outcomes o...
Intraoperative hemodynamic management is challenging because precise assessment of the adequacy of the intravascular volume is difficult during surgery. Perfusion index (PI) has been shown to reflect changes i...
The incidence of postoperative nausea and vomiting (PONV) is higher in patients receiving volatile anesthetics than those receiving total intravenous anesthesia (TIVA) with propofol. However, it is unclear whe...
Hemoglobin Kansas (Hb Kansas) is a rare disease with cyanosis.
Long-term opioid treatment for chronic non-cancer pain has become controversial, given the increasing prevalence of opioid dependence. However, there is little information on therapeutic strategies for this co...
The use of deep pericardial suture (DPS) is a widely used technique to lift the heart and expose the targeted vessels during off-pump coronary artery bypass grafting (OPCAB). Several reports alert massive blee...
The right external iliac vein (REIV) is often used for portal vein reconstruction in patients undergoing pancreatoduodenectomy with portal-superior mesenteric vein resection. We report a case of cardiac arrest...
Hypertrophic obstructive cardiomyopathy (HOCM) is a type of hypertrophic cardiomyopathy associated with left ventricular outflow tract stenosis. The increased pressure gradients across the left ventricular out...
The Geriatric Nutritional Risk Index (GNRI) based on serum albumin level and body weight and the Controlling Nutritional Status Score (CONUT) based on serum albumin level, total cholesterol level, and total ly...
Patients with renal failure are susceptible to electrolyte disturbances including life-threatening hyperkalemia, and intraoperative hepatic damage exacerbates it. We report a case on hemodialysis who developed...
Severe mitral regurgitation (MR) after aortic valve replacement (AVR) is a serious complication. Although several causes of MR after AVR have been reported, severe MR due to geometric changes in the mitral val...
Although 5-aminolevulinic acid (5-ALA) is used for the photodynamic diagnosis of bladder tumors, hypotension is the most commonly observed adverse effect. We present a case of 5-ALA-induced severe hypotension ...
Video-assisted thoracoscopic surgery (VATS) is usually performed under general anesthesia with a double-lumen tube. Recently, VATS without tracheal intubation in a patient with severe respiratory dysfunction h...
Urea cycle disorders are rare; arginase-1 deficiency is one of those extremely rare autosomal recessive metabolic disorders. Arginase-1 is one among the enzymes involved in the production of urea from ammonia ...
Serotonin syndrome is a rare but potentially severe disease, which is caused by hyperstimulation of serotonin receptors in the central nervous system. Several antidepressants exert their effect by modulating i...
Von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. Coagulopathies such as VWD are evidently risk factors for post-surgical bleeding. Perioperative management of patients wit...
Minimally invasive cardiac surgery (MICS) for simple congenital heart defects has become popular, and monitoring of regional cerebral oxygen saturation (rSO2) is crucial for preventing cerebral ischemia during pe...
Retrocaval ureter was diagnosed in a woman complaining of ureteric pain in the last trimester of pregnancy. We describe the rationale behind the administration of epidural analgesia for her colic attack.
Surgeries requiring one-lung ventilation (OLV) in patients with Fontan circulation pose great challenges. However, little information is available regarding the safety of OLV in Fontan patients when hemidiaphr...
Kounis syndrome (KS) is defined as the occurrence of acute coronary syndrome (ACS) associated with an anaphylactic reaction, and there have only been a few reports of its occurrence under general anesthesia.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) can control massive postpartum hemorrhage.
Patients with achondroplasia have various airway deformations and spinal anatomic abnormalities; therefore, performing general anesthesia and neuraxial anesthesia in such patients can be challenging.
Subglottic stenosis is a known complication of traumatic and prolonged endotracheal intubation. It is rare that the causes of severe subglottic stenosis are revealed to be an unexpected foreign body after airw...
Blind epidural catheter placement can lead to inadvertent misplacement. We present a case of intercostal misplacement of a thoracic epidural catheter.
INTELLiVENT®-ASV (iASV) is a respiration mode on the Hamilton G5. The ventilator uses a closed-loop mechanism that automatically adjusts settings related to oxygenation and ventilation.
