RESUMO
Objective To reveal the virulence genes and the polymorphisms of chromosomal 16S rRNA gene of Yersinia enterocolitic strains isolated from different districts in Jiangsu Province,2015. Methods Five virulence genes(ail,virF,yadA,ystA and ystB)of Yersinia enterocolitic strains isolated from different districts in Jiangsu Province were detected by using polymerase chain reaction(PCR),and phylogenetic analysis of chromosomal 16S rRNA gene was performed by amplification and sequencing. Results In this study,73 Yersinia enterocolitic strains were collected in Jiangsu Province in 2015.Among them,56(76.7%)strains carried virulence genes,and ail-virF-yadA -ystA -ystB+were the dominate types in diarrhea patients and other hosts.All strains can be clustering into 4 groups according to the phylogenetic analysis of chromosomal 16S rRNA gene.Conclusions The non-pathogenic Yersinia enterocolitic(ystB+)is the dominant strain in Jiangsu province,and the pathogenic strains are also found in this region.The result of phylogenetic analysis of chromosomal 16S rRNA gene and the profiles of virulence genes are highly consistent.
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
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.
