ABSTRACT
Objective To observe the relations ot vWF,DD concentration and venous thrombosis caused by detaining needle of different time.Sensitive indicators for early prediction of venous thrombosis would be seeked so as to provide theoretical and experimental basis for the selection of intervention time.Methods The detaining needle were placed in the vein of rabbit ears with transfusion.The changes of vWF and DD concentration for the mannitol group and the saline group were measured in different retention time,while the venous thrombosis caused by detaining needle was observed pathologically.Results The results of serological test:(1)vWF concentration:when the needle was detained for 1 day,the vWF concentration of two groups peaked.(2)DD concentration:after the needler was set,the DD concentration of both groups was higher than those before detaining needler.When the needle was detained for 1 day and 3 days,the DD concentration was significantly different from those before using detaining needle.Result of pathological observation:When the needle was detained for 1 day,the venous throm-bosis rate was 100％ for both groups with a moderate degree of thrombosis.Conclusions Detection of the concentration of vWF and DD has certain reference value for predicting detaining needle-induced venous thrombosis.In order to prevent venous thrombosis,intervention should be carried out as soon as possible after detaining needle was set.
ABSTRACT
Objective To know the present situation and the different humanistic caring abilities among college nursing students,so as to provide reference for education training strategy of nursing humanity care.Methods A total of 396 college nursing students were investigated by using the nursing students' humanistic caring ability scale.Results The total score of nursing students' humanistic caring ability was (110.85±21.57),with a scoring rate of 61.59％.Statistically significant differences of humanistic caring ability were found among students of different education levels,different genders and different colleges.Conclusions The level of nursing students' humanistic caring ability was low,so nursing schools and clinical teaching hospitals should strengthen the training of students' humanistic caring ability according to the characteristics of different education level,and take effective training strategies to improve college nursing students' humanistic caring ability.
