INTRODUCTION The peripheral perfusion index (PI) is a noninvasive numerical value of peripheral perfusion, and the transcutaneous oxygen challenge test (OCT) is defined as the degree of transcutaneous partial pressure of oxygen (PtcO2) response to 1.0 FiO2. The value of noninvasive monitoring peripheral perfusion to predict outcome remains to be established(More)
Cardiac pheochromocytoma is relatively rare. Few reports describe the intraoperative and postoperative progression of patients experiencing a life-threatening pheochromocytoma crisis treated with extracorporeal membrane oxygenation (ECMO).A 35-year-old man was referred to our facility for paroxysmal hypertension with a 10-year history of sweating,(More)
BACKGROUND Previous studies have suggested that β1-receptor blockers benefit septic shock patients. This study aimed to determine whether β1-receptor blockers benefit tissue perfusion in sepsis and to identify parameters to reduce the risk of this drug in sepsis. METHODS Consecutive septic shock patients were recruited from the Intensive Care Unit of(More)
BACKGROUND Electrical impedance tomography (EIT) is a real-time bedside monitoring tool, which can reflect dynamic regional lung ventilation. The aim of the present study was to monitor regional gas distribution in patients with acute respiratory distress syndrome (ARDS) during positive-end-expiratory pressure (PEEP) titration using EIT. METHODS Eighteen(More)
The aim of this study is to determine the mechanism of sepsis-induced vascular hyperpermeability and the beneficial effect of glucocorticoid in protecting vascular endothelium. Male Sprague-Dawley rats were given either a bolus intraperitoneal injection of a nonlethal dose of LPS (Escherichia coli 055:B5, 10 mg/kg, Sigma) or vehicle (pyrogen-free water).(More)
AIM Identification of a novel gene in mouse testis and its relation to spermatogenesis. METHODS Genes expressed during different developmental stages of the mouse testis were screened by DNA microarray. The results of chip analysis were authenticated by reverse transcription-polymerase chain reaction (RT-PCR) technique, as well as the tissue distribution(More)
BACKGROUND Setting lactate kinetics at >30% might improve the clinical outcomes of patients with sepsis-associated hyperlactatemia. The aim of this study was to explore the outcome benefits of stepwise lactate kinetics vs central venous oxygen saturation (ScvO2)-oriented hemodynamic therapy at 6 h as the protocol goal during early resuscitation. METHODS(More)
OBJECTIVES Several studies have investigated the prognostic value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in patients with infection. However, the result was controversial. Thus, the purpose of the present meta-analysis was to determine the prognostic value of the sTREM-1 level in predicting mortality at the initial stage of(More)
BACKGROUND The dilemma of pathogens identification in patients with unidentified clinical symptoms such as fever of unknown origin exists, which not only poses a challenge to both the diagnostic and therapeutic process by itself, but also to expert physicians. METHODS In this report, we have attempted to increase the awareness of unidentified pathogens by(More)
For hemodynamic monitoring, the pressure transducer is suggested to be fixed at the level of the phlebostatic axis in critically ill patients [1,2]. The correction and adjustment of pressure transducer are emphasized in central venous pressure monitoring in clinical practice. The exact position of the transducer is relatively easy to be ignored for invasive(More)
