BACKGROUND The relationship between pre-hospital care and the prognosis of out-of-hospital cardiac arrest (OHCA) caused by respiratory disease is unclear. This study aimed to assess the impact of pre-hospital care on the prognosis of OHCA caused by respiratory disease. METHODS In a nationwide, population-based, observational study, we enrolled 121,081(More)
Among 166 specimens with classical complete transposition, pulmonary or subpulmonary stenosis was present in 22 cases. The bases for obstruction were pulmonary valvular stenosis (one case), membranous subpulmonary stenosis (nine cases), anomalous attachment of the mitral valve to the ventricular septum (five cases) and combinations of causes (seven cases).(More)
OBJECTIVES Although cost analyses for emergency care are essential, data on costs of care for out-of-hospital cardiopulmonary arrest (OHCA) are scarce. The present study aimed to analyze health care costs related to OHCA using a nationwide administrative database in Japan. METHODS Using the Diagnosis Procedure Combination database in Japan, we identified(More)
Population aging has rapidly advanced throughout the world and the elderly accounting for out-of-hospital cardiac arrest (OHCA) has increased yearly.We identified all adults who experienced an out-of-hospital cardiac arrest in the All-Japan Utstein Registry of the Fire and Disaster Management Agency, a prospective, population-based clinical registry,(More)
BACKGROUND Unwitnessed OHCA patients with non-shockable initial rhythms account for nearly half of all OHCA patients, and their prognosis is extremely poor. To date, no studies have focused on these patients. This study aimed to investigating the predictors of favorable and poor prognosis in these patients. METHODS We conducted a nationwide,(More)
A pathologic study of the cardiac conduction system was performed in 57 patients who died within 30 days after aortic valvular replacement. Histologically, there were old and recent lesions present in 34 (60 percent) and 43 (75 percent) of the patients, respectively. Old lesions did not show meaningful correlation with preoperative electrocardiograms.(More)
Echocardiographic and necropsy studies were performed in 304 patients with various cardiac diseases. The overall prevalence of disproportionate ventricular septal thickening (septal to free wall ratio greater than or equal to 1.3) was 10%. However, it was related to the type of cardiac lesion. Prevalence was high (greater than 20%) in pulmonary stenosis or(More)
The effect of prehospital epinephrine on neurological outcome in out-of-hospital cardiac arrest (OHCA) is still controversial. We sought to determine whether prehospital epinephrine administration was associated with improved outcomes in adult OHCA. A nationwide, population-based, propensity score-matched study of OHCA patients from January 1, 2011, to(More)
BACKGROUND Conventional cardiopulmonary resuscitation (CPR) (chest compression and rescue breathing) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA) because of the asphyxial nature of the majority of pediatric cardiac arrest events. However, the clinical effectiveness of additional rescue breathing (conventional CPR) compared with(More)
BACKGROUND Cerebral regional oxygen saturation (rSO2) can be measured immediately and noninvasively just after arrival at the hospital and may be useful for evaluating the futility of resuscitation for a patient with out-of-hospital cardiopulmonary arrest (OHCA). We examined the best practices involving cerebral rSO₂ as an indicator of the futility of(More)
