ABSTRACT
Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.
ABSTRACT
Objective To explore the problems and solving countermeasures in application of nursing vertical management,and provide references for nursing post management reform.Methods Through purposive sampling method,nursing administers,clinical nurses,heads of clinical departments and performance directors from five hospitals were interviewed by semi-structured interview method.Data were analyzed using 7-step Colaizzi's phenomenological analysis method.Results Four themes were formed about the problems in application of nursing vertical management,including:affecting department management and doctor-nurse collaboration,insufficient scientificity and fairness of performance evaluation,significant issues regarding post setting of senior nurses,competence and sense of belonging of temporarily deployed nurses.Four themes were formed about the solving countermeasures in application of nursing vertical management,including:improving participation of clinical departments in nursing management,making performance system to public and asking advices of nurses,providing career development for senior nurses,and conducting standardized training and establishing reserve nurses tank.Conclusion The main problems in application of nursing vertical management consisted of affecting department management and doctor-nurse collaboration,insufficient scientificity and fairness of performance evaluation,post setting of senior nurses,and competence and sense of belonging of temporarily deployed nurses.We suggested to better apply nursing vertical management by improving participation of clinical department in nursing management,making performance system to public and asking advices of nurses,providing career development for senior nurses,and conducting standardized training and establishing reserve nurses tank.
ABSTRACT
This paper presented the thinking of security problems of the pulse pressure transducer which was widely used in TCM field. And we suggest that the selection of the pulse sensor should be flexible, the pressure should be comply with the security value of the body's tolerance range, and pulse instrument operator should pay attention to the accuracy and safety, so that the pulse instrument will be more humane, scientific and security-oriented.
ABSTRACT
Objective To explore the distinguishing method and threshold of optimum pulse pressures on Cun pulse and Chi pulse to solve the problem how to exert pressure upon Three Regions Pulse Detecting Instrument.Methods Totally 55 subjects meeting the inclusion criteria were collected.The data of optimum pulse pressures on Cun Guan Chi of the same hand of the same tested person were collected respectively and the comparative analysis on the data was carried out.Results In normal subjects,the attenuation degree of optimum pulse pressures on Guan pulse compared with Cun pulse was 0.189?0.053,and the attenuation degree of optimum pulse pressures on Chi pulse in comparison with Guan pulse was 0.226?0.044.Conclusion Through calculating the attenuation degree of optimum pulse pressures reasonably,the identified threshold of Cun and Chi pulses can be judged from the threshold of Fu-superficial,Zhong-medium,and Chen-deep of Guan pulse.
