ABSTRACT
Objective To explore the effect of two methods on phlebitis induced by peripherally intravenously infused dopamine. Methods One hundred and ninety-five patients with phlebitis caused by peripherally intravenously infused dopamine were randomly divided into experiment group and control group according to the parity of hospitalization number in our department during September 2013 to December 2014. Ninety-eighty cases were assigned in the experiment group and 97 in the control group. In the control group, the venous infusion was done with 24G common intravenous detaining needle and general micro pump infusion extension tube. In the experiment group, it was done with 24G safety intravenous detaining needle, disposable connecting pipe with precision filter and DuoDERM attached to the needle wing of puncture site and its upper skin. The two groups were compared in terms of the incidence and occurrence time of phlebitis. Results The incidence of phlebitis in the experiment group was significantly lower than that of the control group, and its severity significantly lower than that of the control group. In addition, the occurrence time was significantly longer than that in the control group. Conclusion Venous infusing with 24G safety intravenous detaining needle, disposable connecting pipe with precision filter, and DuoDERM attached to the needle wing of puncture site and its upper skin can effectively reduce the incidence and occurrence time of phlebitis caused by dopamine.
ABSTRACT
Genetic diversity of Lilium sargentiae was detected in this paper by sequence-related amplified polymorphism (SRAP) marker. One hundred wild samples were collected from 10 places, and 15 SRAP primer combinations were used for determination. NTSYS-pc2.1 and POPGEN1.32 were used for data analysis. The results showed that a total of 170 clear DNA bands were amplified, 163 of which were polymorphic. The proportion of polymorphic loci was 90.58% on the level of species. Nei's (1973) gene diversity (H) was 0.2631, Shannon's Information index was 0.3661, the G(st), was 0.3672, and the genetic distance ranged from 0.2021 to 0.5749. All materials could be clustered into four groups by UPGMA. The results demonstrated that the genetic diversity of L. sargentiae was rich on the level of species, and the genetic diversity within populations exceeded among populations. The correlations of genetic diversity and distribution were significant in L. sargentiae.
