RESUMO
Objective To explore the application and nursing care of patients with severe burn patients with scar skin treated by ultrasound-guided PICC catheter placement. Methods Twelve patients with burn area of more than 95% were treated with intravenous catheter placement of PICC under the condition of scar hyperplasia skin with the help of ecg. Results Ten patients in elbow basilic vein catheterization by PICC disposable puncture, 1 cases of catheter in the right upper arm of the basilic vein into vascular sheath scar after guidewire dilating the skin in place leading to vascular sheath damaged anterior guidewire failed in bending catheter, to your left arm to venous catheter success, 1 cases of catheter for initial puncture puncture into the insufficient experience in successful puncture needle when the guide wire back because of scar skin relaxation will not needle guide wire fixing the wire with a lead to two times of puncture, 12 cases of catheter tip position by X-ray showed in the superior vena cava under 1/3, indwelling time ranged from-11 months of March, in the retention period without related complications. Conclusions It is feasible and advantageous for the application of PICC catheter in the treatment of severe burn patients with scar skin.

RESUMO
Objective To investigate the practice and effect of specialist nursing inspection of intravenous infusion in the quality control of specialist nursing. Methods Intravenous infusion treatment nursing group used feed-forward control theory and methods, taking cross-sectional research methods yearly from 2014 to 2016 and referencing intravenous infusion special quality checklist to fully understand the hospital infusion tool selection situation and quality. Intravenous infusion related treatment system operational procedures was established and improved, the monthly quality control plan was made to do quality nursing of intravenous infusion specialist inspections and timely feedback of each month to various sections of the hospital. Results The rational choice of the hospital infusion tool was more reasonable. The proportion of steel needle in 2016 compared with in 2015 and 2014 was decreased by 8.9%(321/920-212/846), 18.8%(321/920-156/968). Intravenous infusion quality was significantly improved in the catheters′normative fix, nursing staffs′mastery of the skills and related expertise control rate, intravenous infusion treatment-related complications e.g. Phlebitis above grade two in 2016 were reduced 22 cases and 30 cases compared with in 2015 and in 2014, meanwhile the number was 18 and 31 in drug extravasation case. Conclusions Special nursing of intravenous infusion has a good effect on the improvement of nursing quality, and feed-forward control is an effective method for quality control of intravenous infusion therapy.
RESUMO
An uncoded transmission scheme called SoftCast has recently shown great potential for wireless video transmission. Unlike conventional approaches, SoftCast processes input images only by a series of transformations and modulates the coefficients directly to a dense constellation for transmission. The transmission is uncoded and lossy in nature, with its noise level commensurate with the channel condition. This paper presents a theoretical analysis for an uncoded visual communication, focusing on developing a quantitative measurements for the efficiency of decorrelation transform in a generalized uncoded transmission framework. Our analysis reveals that the energy distribution among signal elements is critical for the efficiency of uncoded transmission. A decorrelation transform can potentially bring a significant performance gain by boosting the energy diversity in signal representation. Numerical results on Markov random process and real image and video signals are reported to evaluate the performance gain of using different transforms in uncoded transmission. The analysis presented in this paper is verified by simulated SoftCast transmissions. This provide guidelines for designing efficient uncoded video transmission schemes.
