Few topics in operative and perioperative patient management generate more controversy than that of appropriate fluid and electrolyte therapy. especially, controversy has swirled around colloid vs crystalloid therapy and the composition of administered fluids, agreement among clinicians as to what fluid therapy is appropriate, and in what amount, is rare. This controversy likely will be enhanced by Arieff' s provocative article. He described 11 adults and 2 pediatric patients. All developed fatal postoperative pulmonary edema, seemingly caused solely by excessive postoperative fluid administration. From January 1999 to December 1999, we investigated 24 patients, which were operated by orthognathic surgery, about the intraoperative fluid therapy and the associated effect in orthognathic surgery, which is regarded as one of the major surgery of oral and maxillofacial surgery. First, They were devided into two groups, that is one-jaw surgery and two-jaw surgery, and each groups were devided by intraoperative fluid volume of 8ml/kg/hr. Subjective assesment was collected through use of a series of 3 questionnaries. In each questionnaire, a 5-point Liekert scale was used far assessment of following parameters of recovery from anesthesia: headache, dizziness, drowsiness, nausea/vomiting, thirst. The patient completed questionnaire 1 at 4 hour after surgery, questionnaire 2 was completed at 24 hours after surgery, and questionnaire 3 was completed at 48 hours after surgery. This study demonstrated that appropriated perioperative rehydration decreases postoperative adverse outcomes and improved the patient's perception of the postoperative period.

<P>Transparent electrodes that can maintain their electrical and optical properties stably against large mechanical deformations are essential in numerous applications of flexible and wearable electronics. In this paper, we report a comprehensive analysis of the electrical, optical, and mechanical properties of hybrid nanostructures based on graphene and metal nanotrough networks as stretchable and transparent electrodes. Compared to the single material of graphene or the nanotrough, the formation of this hybrid can improve the uniformity of sheet resistance significantly, that is, a very low sheet resistance (1 Ω/sq) with a standard deviation of less than ±0.1 Ω/sq, high transparency (91% in the visible light regime), and superb stretchability (80% in tensile strain). The successful demonstration of skin-attachable, flexible, and transparent arrays of oxide semiconductor transistors fabricated using hybrid electrodes suggests substantial promise for the next generation of electronic devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2014/nalefd.2014.14.issue-11/nl502755y/production/images/medium/nl-2014-02755y_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl502755y'>ACS Electronic Supporting Info</A></P>

<P>We report an Ag nanofiber-embedded glass-fabric reinforced hybrimer (AgNF-GFRHybrimer) composite film as a reliable and high-performance flexible transparent conducting film. The continuous AgNF network provides superior optoelectronic properties of the composite film by minimizing transmission loss and junction resistance. In addition, the excellent thermal/chemical stability and mechanical durability of the GFRHybrimer matrix provides enhanced mechanical durability and reliability of the final AgNF-GFRHybrimer composite film. To demonstrate the availability of our AgNF-GFRHybrimer composite as a transparent conducting film, we fabricated a flexible organic light-emitting diode (OLED) device on the AgNF-GFRHybrimer film; the OLED showed stable operation during a flexing.</P>
