Summary The aim of the present study was to determine precision PiCCO ® system for post‐cardiac arrest patients who underwent therapeutic hypothermia. measurements cardiac output, global end‐diastolic volume, extravascular lung water and pulmonary vascular permeability index assessed using least significant change; this regarded as precise when less than 15%. A total 462 measurement sets were prospectively performed on 88 following successful resuscitation after arrest. Using mean value...

On March 11, 2011, after the Great East Japan Earthquake and tsunami, government declared a nuclear emergency following damage to Fukushima Daiichi Nuclear Power Plant. A second hydrogen explosion occurred on 14 at plant's No. 3 reactor injured 11 people. At that time prime minister urged people living 20 30 km from plant stay indoors. Under these circumstances, many residents of Iwaki City, which was largely outside 30-km zone, left city, making it difficult get supplies remaining...

In Japan, standard prehospital care is provided by emergency medical services teams. Doctor-staffed ambulances play a role in facilitating the immediate treatment of critically ill patients to increase survival rates. However, little known about their activities. We revealed present situation doctor-staffed Japan.First, we surveyed all fire departments Japan and determined whether ambulance was within district boundary. Second, hospitals that operate system list activities during 1-week...

Abstract In a mass decontamination during nuclear, biological, or chemical (NBC) response, the capability to command, control, and communicate is crucial for proper flow of casualties at scene their subsequent evacuation definitive medical facilities. Information Technology (IT) tools can be used strengthen communication such response. Novel IT comprise vehicle-based, remote video camera network systems. During an on-site verification event, image from system attached personal protective...

Intravenous immunoglobulin (IVIG) therapy has been used to treat sepsis, but its mechanisms of action remain unclear. Sepsis causes multiple organ failure, such as acute lung injury (ALI), which involves apoptosis alveolar epithelial cells. In this study, we hypothesized that IVIG suppresses in cells and evaluated mortality, cytokine levels, histological changes the lung, cell after administration, mice with experimentally induced sepsis.Mice received an injection vehicle (saline) or (100...

The large PAPR of orthogonal frequency division multiplexing (OFDM) transmission is one the serious problems for mobile communications that require severe power saving. Iterative clipping and filtering an effective method reduction OFDM signals. This paper evaluates effect with a graded band-limiting filter in iterative method. evaluation result by computer simulation shows excellent peak can be obtained fewer iteration numbers using roll-off instead conventional rectangular filter, number...

Rapid induction and maintaining a target temperature of 32.0-36.0°C within narrow range for <24 hours are essential, but those very hard to perform in postcardiac arrest syndrome (PCAS) patients. We investigated the usability an intravascular management (IVTM) system with neurolept-anesthesia (NLA; droperidol fentanyl). Single-arm, prospective multicenter trial was carried out seven university three affiliated hospitals. In 24 comatose PCAS patients, (33.0°C) rapidly induced maintained using...

Portal venous gas (PVG) and pneumatosis intestinalis (PI) are rare pathologic findings, a delayed appearance of portal vein thrombosis (PVT) in such patients is extremely rare.A 51-year-old man complaining epigastric pain was referred to our hospital. Computed tomography (CT) at admission revealed massive PVG extensive PI, but no PVT. Emergency laparotomy carried out, bowel resection unnecessary.

Background: Succinate dehydrogenase (SDH) is a key enzyme involved in succinate accumulation during ischemia and its subsequent oxidation upon reperfusion, leading to excessive reactive oxygen species production. Malonate, competitive inhibitor of SDH, has emerged as promising candidate for selective SDH inhibition reduce reperfusion injury. However, studies targeting metabolism neuroprotection after cardiac arrest (CA) cardiopulmonary resuscitation (CPR) are still extremely limited. Methods...

Background: Inhaled molecular hydrogen gas (H 2 ) has been shown to improve outcomes in both animal models and patients of cardiac arrest (CA). Although the mechanisms H2 have studied, impacts H on metabolic alterations following CA remain be elucidated. Methods: Rats were subjected 10 minutes asphyxial followed by CPR achieve a return spontaneous circulation (ROSC). Ten after achieving ROSC, rats mechanically ventilated with 21% O (Air group) or plus 1.3% group). Whole-brain plasma samples...

Injuries of the celiac artery and its branches are rare, but potentially lethal. Ligation these arteries is performed to control significant hemorrhage. However, few reports have described adverse effects ligating arteries. A 69-year-old woman with a self-inflicted stab wound was brought our hospital. Her blood pressure could not be measured, therefore aortic cross-clamping performed, epinephrine administered for resuscitation, an emergency laparotomy roots splenic common hepatic were...

Pulmonary dysfunction after cardiac arrest is a common phenomenon. Evidence appears to support the usefulness of quanti-tative assessment pulmonary using extravascular lung water (EVLW) and vascular permeability index (PVPI). We hypothesized that duration (CPA TIME) would impact in patients with postcardiac syndrome. The aim present study was investigate quantitatively EVLW PVPI successfully resuscitated (CPA).
