The acute respiratory distress syndrome (ARDS) is a syndrome of acute respiratory failure associated with severe inflammation and diffuse alveolar damage. Recent studies have demonstrated that the soluble receptor for advanced glycation end products (sRAGE) plays an important role in the pathogenesis of ARDS. The aim of this study was to ascertain whether plasma levels of sRAGE were elevated in ARDS patients compared with appropriate controls. ⋯ There was no significant difference in plasma sRAGE levels between survivors and non-survivors (P=0.34). Our results demonstrate that elevated levels of plasma sRAGE may provide a useful marker for ventilated ARDS patients. Furthermore, the relationship between plasma sRAGE levels and PaO2:FiO2 ratio in the ARDS population provides the hypothesis that ventilatory strategy may influence alveolar epithelial damage in ARDS.

Several studies have suggested that the menstrual cycle has the impact on sedation. No previous study has evaluated the effects of the menstrual cycle on sedation level and propofol requirement with preoperative intravenous dexmedetomidine. Sixty-four adult fertile women receiving general anesthesia for elective gynecologic surgery were included in the study. ⋯ From propofol administered to loss of eyelash reflex and BIS values reach to 50, propofol requirements were significantly least and duration were shortest in the LD group among the four groups. Menstrual cycle phases affect the sedation of propofol induction with preoperative intravenous dexmedetomidine, which is deeper in the luteal phase. We should cautious of excessive sedation by propofol anesthesia with preoperative dexmedetomidine in the luteal phase.

Case Reports
Life-threatening anaphylactic shock due to chlorhexidine on the central venous catheter: a case series.
In this article, we report two life-threatening anaphylactic shocks by an antiseptic coated central venous catheter (CVC) within a 6-month period in our cancer center. Anaphylactic shock was preceded immediately after insertion of a central venous catheter (CVC) coated with silver sulphadiazine and chlorhexidine acetate (Blue FlexTip(®) ARROWg(+)ard Blue(®), 14Ga, Arrow International, Inc. ⋯ Though antiseptic coated CVC anaphylaxis has been reported in Japan, Europe and America, to our knowledge, this is first reported in China. We present these rare cases to remind clinicians about hypersensitivity to chlorhexidine that could potentially be life-threatening.

This study is to test the effectiveness of fiber-optic-guided endotracheal suction catheter (visual sputum suctioning system or VSSS) in dog models. ⋯ Visual sputum suctioning system collected more sputum and caused less tracheal mucosa damage than conventional suctioning.

To compare the different outcomes of dexmedetomidine (Dex) vs. propofol combined with sevoflurane in children's laparoscopic surgery by noninvasive continuous cardiac output monitoring (NICOM). ⋯ Compared with propofol, the combination of Dex in children undergoing laparoscopic surgery shows better inhibition on HR.
