Abstract In adult high-frequency oscillatory ventilation (HFOV), stroke volume (SV) and mean lung pressure (PLung) are important for lung protection. We measured the airway pressure at the Y-piece and the lung pressure during HFOV using a lung model and HFOV ventilators for adults (R100 and 3100B). The lung model was made of a 20-liter, airtight rigid plastic container (adiabatic compliance: 19.3ml/cmH2O) with or without a resistor (20cmH2O/l/sec). The ventilator settings were as follows: mean airway pressure (MAP), 30cmH2O;frequency, 5-15Hz (every 1Hz);airway pressure amplitude (AMP), maximum;and % of inspiratory time (IT), 50% for R100, 33% or 50% for 3100B. The measurements were also performed with an AMP of 2/3 or 1/3 maximum at 5, 10 and 15Hz. The PLung and the measured MAP were not consistently identical to the setting MAP in either ventilator, and decreasing IT decreased the PLung in 3100B. In conclusion, we must pay attention to the possible discrepancy between the PLung and the setting MAP during adult HFOV.

Abstract Hyponatremia, a common electrolyte disorder associated with traumatic brain injuries (TBIs), has high mortality and morbidity rates. The aim of this study was to identify the risk factors for hyponatremia associated with TBI. We retrospectively analyzed the cases of TBI patients who were admitted to the emergency intensive care unit at Okayama University Hospital between October 2011 and September 2014. A total of 82 TBI patients were enrolled. The incidences of hyponatremia (serum sodium level of<135mEq/L) and severe hyponatremia (serum sodium level of<130mEq/L) within the first 14 days after admission were 51オ (n=42) and 20オ (n=16), respectively. After admission, hyponatremia took a median period of 7 days to develop and lasted for a median of 3 days. Multivariate analysis demonstrated that higher fluid intake from days 1 to 3 and the presence of cranial fractures were risk factors for hyponatremia. The 58 patients with hyponatremia experienced fewer ventilator-free days, longer intensive care unit stays, and less favorable outcomes compared to the 24 patients without hyponatremia;however, these differences were not significant. Further studies are needed to determine the optimal management strategy for TBI-associated hyponatremia in the intensive care unit setting.

Abstract We sought to identify the incidence, injury patterns, and financial burden of ladder fall injuries to provide a reference for reinforcing guidelines on the prevention of such injuries. We enrolled the patients who were injured in a ladder-related fall and required intensive care between April 2012 and March 2014 at Okayama University Hospital, a tertiary care hospital in Okayama City:9 patients injured in 7 stepladder falls and 2 straight ladder falls. The median patient age was 69 years, and 8 were males. Six falls occurred in non-occupational settings. Head injuries predominated, and the injury severity score ranged from 2 to 35 (mean=21±12). At the time of discharge from the intensive care unit, one patient had died and 5 patients had some neurological disabilities. The case fatality rate was 11%. The total cost of care during the review period was ¥16,705,794, with a mean cost of ¥1,856,199 per patient. Ladder fall injuries are associated with a high rate of neurological sequelae and pose a financial burden on the health insurance system. A prevention education campaign targeting at older-aged males in non-occupational settings may be a worthwhile health service investment in this community.

Abstract In recent years, it has become evident that molecular hydrogen is a particularyl effective treatment for various disease models such as ischemia-reperfusion injury; as a result, research on hydrogen has progressed rapidly. Hydrogen has been shown to be effective not only through intake as a gas, but also as a liquid medication taken orally, intravenously, or locally. Hydrogenʼs effectiveness is thus multifaceted. Herein we review the recent research on hydrogen-rich water, and we examine the possibilities for its clinical application. Now that hydrogen is in the limelight as a gaseous signaling molecule due to its potential ability to inhibit oxidative stress signaling, new research developments are highly anticipated.

Abstract Worldwide, hemorrhagic shock in major trauma remains a major potentially preventable cause of death. Controlling bleeding and subsequent coagulopathy is a big challenge. Immediate assessment of unidentified bleeding sources is essential in blunt trauma patients with hemorrhagic shock. Chest/pelvic X-ray in conjunction with ultrasonography have been established classically as initial diagnostic imaging modalities to identify the major sources of internal bleeding including intra-thoracic, intra-abdominal, or retroperitoneal hemorrhage related to pelvic fracture. Massive soft tissue injury, regardless of whether isolated or associated with multiple injuries, occasionally causes extensive hemorrhage and acute traumatic coagulopathy. Specific types of injuries, including soft tissue injury or retroperitoneal hemorrhage unrelated to pelvic fracture, can potentially be overlooked or be considered “occult” causes of bleeding because classical diagnostic imaging often cannot exclude such injuries. The purpose of this narrative review article is to describe “occult” or unusual sources of bleeding associated with blunt trauma.

Abstract A 38-year-old primipara Japanese woman suffered cardiac arrest due to a pulmonary thromboembolism 1 day after undergoing a cesarean section. Extracorporeal cardiopulmonary resuscitation was initiated and extracorporeal membrane oxygenation support was needed for 24 h. Despite intensive care, the patient was diagnosed with brain death on day 6. With the family’s consent, comprehensive end-of-life care including organ donation was discussed based on our hospital’s policy. The family decided to donate her organs. Specific training and education are required for emergency physicians to optimize the process of incorporating organ donation into end-of-life care while respecting the patient’s and family’s wishes.
