A Case of Fatal Fat Embolism Syndrome During Osteosynthesis Saved by Veno-Arterial Extracorporeal Membrane Oxygenation.

Fat embolism syndrome (FES) occurs when fat droplets from bone marrow or adipose tissue enter the circulation due to bone fractures or surgical interventions. It typically develops 12 to 72 hours after injury. However, fulminant FES, characterized by its rapid onset, is rare and can rapidly progress to a life-threatening condition.

Cardioprotective Effects of Sodium-Glucose Cotransporter Subtype Inhibition on Ischemic and Pharmacological Preconditioning.

Background: Sodium-glucose cotransporter (SGLT) 2 inhibitors partially inhibit SGLT1 expression; however, whether a clinical dose of SGLT2 inhibitor abrogates ischemic preconditioning (IPC) is unknown, and the pharmacological cardioprotective effect under SGLT1 inhibition has not been examined. In this study, we investigated whether a clinical dose of tofogliflozin abrogates IPC and whether pharmacological preconditioning with olprinone has cardioprotective effects under SGLT1 inhibition.

Methods: Male Wistar rats were divided into seven groups (seven rats per group) and subjected to the following treatments before inducing ischemia/reperfusion (I/R; 30 minutes of coronary artery occlusion followed by 120 minutes of reperfusion): saline infusion control treatment (Con); ischemic preconditioning (IPC); IPC after phlorizin infusion (IPC+Phl); IPC after low-dose tofogliflozin infusion (IPC+L-Tof); IPC after high-dose tofogliflozin infusion (IPC+H-Tof); olprinone infusion (Olp); and Olp infusion after phlorizin infusion (Olp+Phl).

Association between enterocyte injury and fluid balance in patients with septic shock: a post hoc exploratory analysis of a prospective observational study.

Background: The required fluid volume differs among patients with septic shock. Enterocyte injury caused by shock may increase the need for fluid by triggering a systematic inflammatory response or an ischemia-reperfusion injury in the presence of intestinal ischemia/necrosis. This study aimed to evaluate the association between enterocyte injury and positive fluid balance in patients with septic shock.

Removal of a catheter mount and heat-and-moisture exchanger improves hypercapnia in patients with acute respiratory distress syndrome: A retrospective observational study.

To avoid ventilator-associated lung injury in acute respiratory distress syndrome (ARDS) treatment, respiratory management should be performed at a low tidal volume of 6 to 8 mL/kg and plateau pressure of ≤30 cmH2O. However, such lung-protective ventilation often results in hypercapnia, which is a risk factor for poor outcomes. The purpose of this study was to retrospectively evaluate the effectiveness and safety of the removal of a catheter mount (CM) and using heated humidifiers (HH) instead of a heat-and-moisture exchanger (HME) for reducing the mechanical dead space created by the CM and HME, which may improve hypercapnia in patients with ARDS.

Anaphylactic shock in a patient with severe aortic stenosis treated with adrenaline and landiolol for circulatory management: A case report.

Rationale: We present the first case of a patient with severe aortic stenosis who developed anaphylactic shock and was successfully treated with adrenaline and landiolol, a highly selective β1-receptor blocker, to prevent disruption of the myocardial oxygen supply-demand balance caused by tachycardia.

Patient Concerns: An 86-year-old woman was scheduled for simultaneous anterior-posterior fixation for a burst fracture of the 12th thoracic vertebra; 200 mg sugammadex, a neuromuscular blocking agent antagonist, was administered postoperatively, and she was extubated without complications. However, 6 min after extubation, her blood pressure decreased abruptly to 55/29 mm Hg, and her heart rate increased to 78 bpm.

Absent right superior vena cava with persistent left superior vena cava in a patient with COVID-19.

Vascular injury associated with cannulation during extracorporeal membrane oxygenation (ECMO) induction is a rare but life-threatening complication. The presence of abnormal vascular anatomy increases the risk of vascular injury and should be recognized before cannulation. We report the case of a patient with coronavirus disease (COVID-19) who was expected to undergo ECMO.

Allergen-Related Coronary Vasospasm "Kounis Syndrome" Requiring Administration of Epinephrine and a Coronary Vasodilator.

Kounis syndrome is an anaphylactic reaction leading to acute coronary syndrome. The acute treatment of anaphylaxis is epinephrine; however, epinephrine may cause coronary vasoconstriction, reduce coronary blood flow, increase myocardial oxygen demand, and worsen myocardial ischemia. On the other hand, coronary vasodilation, a treatment for acute coronary syndrome, can aggravate hypotension in patients with anaphylaxis.

Association between endotoxemia and enterocyte injury and clinical course in patients with gram-positive septic shock: A posthoc analysis of a prospective observational study.

Endotoxemia often occurs in patients with gram-positive infections. The possible mechanism is thought to be bacterial translocation after enterocyte hypoperfusion injury. However, the association between endotoxemia and enterocyte injury among patients with gram-positive septic shock has never been assessed.

[An Analysis of Autologous Blood Transfusion in Major Orthopedic Surgery : Our Experience with 2,262 Patients.].

Background: Allogenic blood transfusion accompa- nies the risks of infection, allergic reaction, and immune suppression. We analyzed the patients having autolo- gous blood transfusion in major orthopedic surgery in our hospital.

Methods: We analyzed 2,262 patients scheduled for autologous transfusion for the last 22 years (from Sep- tember 1991 to September 2013) retrospectively.

[A Case of Acetaminophen Poisoning Associated with Tramcet Overdose].

Tramcet is a mixture of tramadol and acetaminophen. Acetaminophen poisoning may be caused by excessive intake of Tramcet. A 17-year-old female took excessive quantity of Tramcet before noon.

Comparative efficacy of levobupivacaine and ropivacaine for epidural block in outpatients with degenerative spinal disease.

Background: Levobupivacaine has less toxic potential on both the cardiovascular and central nervous system and has been widely used for postoperative epidural analgesia in surgical patients. However, there are few reports on the efficacy of epidural levobupivacaine in outpatients with lumbosacral radiculopathy. This study was carried out to evaluate the comparative efficacy of levobupivacaine and ropivacaine for epidural block in outpatients with degenerative spinal disease and sciatica.
