INTRODUCTION Fever is frequently observed in critically ill patients. An independent association of fever with increased mortality has been observed in non-neurological critically ill patients with mixed febrile etiology. The association of fever and antipyretics with mortality, however, may be different between infective and non-infective illness. (More)
OBJECTIVE Two series of experiments were designed to evaluate whether early arginine vasopressin improves acute outcome following resuscitation from traumatic brain injury and severe hemorrhagic hypotension. DESIGN Prospective randomized, blinded animal study. SETTING University laboratory. SUBJECTS Thirty-three swine. INTERVENTIONS In series 1 (n =(More)
BACKGROUND The purpose of the study was to compare initial resuscitation with arginine vasopressin (AVP), phenylephrine (PE), or isotonic crystalloid fluid alone after traumatic brain injury and vasodilatory shock. STUDY DESIGN Anesthetized, ventilated swine (n = 39, 30 +/- 2 kg) underwent fluid percussion traumatic brain injury followed by hemorrhage (30(More)
UNLABELLED Arginine vasopressin (AVP) is a promising treatment for several types of irreversible shock, but its therapeutic potential has not been examined after severe chest trauma. Two series of experiments were performed to fill this gap. METHODS Series 1: anesthetized, mechanically-ventilated pigs (n = 20, 29 +/- 1 kg) received a blast to the chest,(More)
BACKGROUND Although high-molecular-weight hydroxyethyl starch (HES) has been reported to cause acute kidney injury (AKI), it is not clear whether low-molecular-weight HES (6% HES 70/0.5) can be a risk for AKI or not. We hypothesized that intraoperative 6% HES 70/0.5 administration is not related to postoperative AKI. METHODS A retrospective chart review(More)
To compare the attitudes of physicians towards withholding and withdrawing life-sustaining treatments in intensive care units (ICUs) in low-middle-income Asian countries and regions with those in high-income ones, and to explore differences in the role of families and surrogates, legal risks, and financial considerations between these countries and regions.(More)
Recombinant human soluble thrombomodulin (rhTM) is a novel class of anticoagulants for treating disseminated intravascular coagulation (DIC). Although rhTM is widely used in clinical settings throughout Japan, there is limited clinical evidence supporting the use of rhTM in patients with sepsis-induced DIC. Furthermore, rhTM is not approved for DIC(More)
Little evidence exists regarding the need for a reduction in postoperative heart rate after repair of type A acute aortic dissection. This single-center retrospective study was conducted to determine if lower heart rate during the early postoperative phase is associated with improved long-term outcomes after surgery for patients with type A acute aortic(More)
OBJECTIVES A volume-outcome relationship in ICU patients has been suggested in recent studies. However, it is unclear whether the ICU-to-hospital bed ratio affects the volume-outcome relationship. The aim of this study is to investigate the relationship between hospital volume and in-hospital mortality of adult ICU patients in relation to the ratio of ICU(More)
Active cytomegalovirus infection is not uncommon in critically ill non-immunosuppressed patients. We conducted a preliminary observational study to determine the prevalence of active cytomegalovirus infection in cardiovascular surgical patients. One hundred patients admitted to the intensive care unit following cardiovascular surgery were enrolled between(More)
