Acute normovolemic hemodilution (ANH) is used to reduce the risk of peri-operative allogeneic blood transfusion. Although crystalloid and/or colloid solutions have been used for volume replacement during ANH, ...
Perforation of the right ventricle by a pacemaker lead is a rare and potentially life-threatening complication. We present a patient who developed right ventricular perforation, pneumothorax, and a cyst and un...
There are few cases of anaphylaxis after local application of fibrin sealant diagnosed by skin tests.
Platypnea–orthodeoxia syndrome (POS) is a rare clinical condition characterized by respiratory distress and/or hypoxia developing in the sitting/upright position, which is relieved in the recumbent position. T...
It is unclear whether perioperative Bispectral Index™ (BIS) monitoring in pediatric cases with acute liver failure (ALF) is effective for evaluation of neurological function. We describe a pediatric patient wi...
It has been suggested that radiating pain during spinal or epidural needle insertion and catheter placement can be an indicator of needle-related nerve injury. In this study, using a historical cohort, we inve...
Few studies examined time-to-time changes of cuff pressure of an endotracheal tube during surgery. We retrospectively analyzed the changes of cuff pressure during thyroid surgery and examined its relationships...
We report a case of COVID-19 with Legionella co-infection that was treated successfully.
Hyperactive dysfunction syndrome (HDS) refers to a constellation of symptoms developing from cranial nerve overactivity caused by neurovascular compression at the root entry or exit zone near the brainstem. Al...
Intrapulmonary percussive ventilation (IPV) facilitates the mobilization and clearance of bronchial secretions. Cricothyroidotomy using a Mini-Trach II device is a minimally invasive method used for secretion ...
Anaphylaxis caused by a catheter itself used for endovascular surgery is rare, and a method for detection of a causative catheter has not been established. We report a case of catheter-induced anaphylaxis in w...
We present a case of COVID-19–positive pediatric patient for urgent urological surgery by spinal anesthesia to avoid aerosolizing procedure.
Laparoscopic surgery for a patient with Fontan physiology is challenging because pneumoperitoneum and positive pressure ventilation could decrease venous return and the accumulated partial pressure of arterial...
Ventilator auto-triggering is associated with poor outcomes. Herein, we present a case of delayed tracheal extubation after cardiac surgery due to cardiogenic auto-triggering.
Glutaric acidemia is a type of multiple acyl-coenzyme A dehydrogenase deficiency, an inborn error in fatty acid metabolism. In patients with glutaric acidemia, during the perioperative period, prolonged fastin...
During pulmonary segmentectomy, identification of the target segment is essential. We used bronchoscopic jet ventilation (BJV) to delineate the intersegmental plane by selectively sending air into the target s...
We tested the hypothesis that the C-MAC® video laryngoscope (C-MAC) with an external display is more useful than the disposable i-view™ video laryngoscope (i-view) with an integrated display or a Macintosh dir...
Systemic anesthetic management of patients with mitochondrial disease requires careful preoperative preparation to administer adequate anesthesia and address potential disease-related complications. The approp...
Pheochromocytomas produce hormones, cytokines, and catecholamines. We report perioperative anesthetic management of a rare interleukin-6 (IL-6)-producing pheochromocytoma.
Spinal nerve block is difficult with minimally invasive cardiac surgery (MICS), because of the risk of serious bleeding complications due to full heparinization. Continuous extrapleural intercostal nerve block...
Most patients with congenital tracheal stenosis (CTS) develop respiratory symptoms early in life. CTS remaining undiagnosed until adulthood is rare.
Patients with spinal cord injury (SCI) frequently complain of intractable pain that is resistant to conservative treatments. Here, we report the successful application of 1-kHz high-frequency spinal cord stimu...
Although most epidural catheter knot formation has been reported in lumbar epidural catheter placement, knot formation in a thoracic epidural catheter has been experienced.
Acute onset paraplegia after endovascular aneurysm repair (EVAR) is a rare but well-known complication. We here show a 79-year-old woman with paraplegia caused by static and dynamic spinal cord insult not by i...
To prevent cardiac collapse and to protect cerebral function, hypothermic cardiopulmonary bypass is established before resternotomy. However, ventricular fibrillation under hypothermia facilitates left ventric...
Conventional coagulation tests, such as prothrombin time and activated partial thromboplastin time, are not sensitive to anticoagulation by apixaban. We evaluated the antithrombotic effect of apixaban using a ...
Various attempts have been made to meet patient desires, especially among younger and otherwise healthy individuals, for cosmetically satisfying incision with atrial septal defect (ASD) repair. One of procedur...
The prospect of patients with obstructive respiratory dysfunction undergoing surgery has increased with the growth in the elderly population; however, there have been few investigations about the recovery prof...
Patients with an anterior mediastinal mass are at risk of perioperative respiratory collapse.
The IMPELLA® is a minimally invasive left ventricular assist device. We report a case in which transesophageal echocardiography (TEE) was useful in diagnosis of left ventricular rupture after IMPELLA® insertion.
Prophylactic antibiotics and neuromuscular blocking agents (NMBA) are two of the major causative agents of anaphylaxis after induction of anesthesia.
Coronary artery spasm has rarely been reported in pediatric patients. Previous studies have reported comorbidities and risk factors for coronary artery spasms. We present the case of a complete atrio-ventricul...
The depth of anesthesia (DOA) is estimated based on the anesthesia-induced electroencephalogram (EEG) changes. However, the surgical environment, as well as the patient him/herself, generates electrical interf...
Cancer pain management in children is challenging owing to their unique patient characteristics. We present the case of a 10-year-old girl whose cancer pain was successfully managed using an intrathecal neurol...
The Postoperative Quality of Recovery Scale (PostopQRS) is a survey-based tool that measures quality of the postoperative recovery in multiple domains over multiple time periods. The purpose of this study is t...
Ultrasound-guided supra-inguinal fascia iliaca block (SFIB) is widely used as regional anesthesia of the hip and thigh. It is difficult to judge the blocking effect and the spreading local anesthesia. We hypot...
The number of robot-assisted surgeries being performed has increased in recent years, even in patients with risk factors, such as obesity, owing to advancements in medical technologies. We here report the anes...
Anesthetic management of coronary artery bypass grafting surgery (CABG) in a dextrocardia patient with situs inversus totalis is rarely encountered and seldom reported in the literature.
The optimal intraoperative blood pressure range and crystalloid administration protocol for the prevention of acute kidney injury (AKI) after elective noncardiac surgery remain unknown.
We report a case in which a list of high-risk pregnant women on cloud-based business communication tools was useful in formulating an anesthetic plan for unscheduled cesarean section.
Anticoagulation management of patients with antiphospholipid syndrome (APS) undergoing cardiac surgery is challenging due to the prolongation of activated clotting time (ACT). Currently, no study has compared ...
Fibrinogen concentration is an important indicator of the treatment for obstetric disseminated intravascular coagulation (DIC). We present how using the fibrinogen measuring device could solve problems in the ...
