Objective To investigate the effects of two different arm postures on radial artery puncture. Methods We randomly divided 100 patients into control group and experiment group according to the operation sequence, 50 patients in each group. In the control group, the traditional method was used for radial artery puncture and sheath placement, while in the experiment group the modified method was used. Result Compared with the control group, the success rate of radial artery puncture in the experiment group was significantly higher (P<0.05), and the time needed was significantly shorter (P<0.05). Conclusions The modified arm posture for radial artery puncture and sheath placement is more effective for exposure of the radial artery puncture point and ensure the stability of the puncture site. With this method, we can improve the success rate of radial artery puncture and shorten the puncture time. It is worthy of clinical application.

Objective To evaluate the nursing strategies about implantation of NeoVas TM biodegradable drug (rapamycin) eluting stents and to provide references for clinical application in the future .Methods A prospective, multicenter, single-blind, randomized controlled study was performed to evaluate the safety and effectiveness of NeoVas TM biodegradable stents .Ten patients with coronary artery disease were enrolled in Department of Cardiac Catheterization , Peking Union Medical College Hospital , Chinese Academy of Medical Sciences .The nursing strategies were analyzed and summarized retrospectively .Results Ten patients with coronary artery disease all underwent successful implantations of NeoVas TM biodegradable stents with cooperation of nursing team.None of the participators were excluded .Conclusions Cooperation of nursing team provides powerful guarantee for safe implantation of NeoVas TM biodegradable stents .The nursing strategies are reasonable and practicable .

As an important measure starting for hospital management, hospital accreditation can effectively guide hospitals to improve their comprehensive service capabilities and management level. The accreditation results of 38 tertiary general hospitals in Jiangsu province from 2018 to 2020 showed that there were weaknesses existing in the development of hospitals, including the radiosity and influence of tertiary hospitals, patient service mode, construction of medical technology capabilities and disciplines, medical quality and safety, nursing quality management and specialized nursing, and information construction. The author suggested that hospitals should return to functional positioning, improve the service quality, strengthen construction of hospital disciplines and technical projects, consolidate the foundation of quality and safety management, improve the level of information technology construction, for references for promoting the high-quality sustainable development of tertiary general hospitals.

Objective To develop an arm support used for bilateral puncture during trans-radial coronary intervention (TRI) and to explore its effects. Methods The arm support used for bilateral radial artery puncture was designed and developed. Totally 100 patients who received TRI in the Cardiac Catheterization Room of Peking Union Medical College Hospital between May and June 2017 were selected and equally divided into an observation group and a control group according to the random number table. Patients in the observation group were served with the new arm support to reveal the points for radial artery puncture, while patients in the control group used the conventional wooden arm support. The effect of puncture was compared between the patients in the two groups. Results The time used for preparation before radial artery puncture was (1.58±0.56) min and the time need for puncturing and placing sheathing canal in the radial artery was (3.51±0.44) min in the patients in the observation group, both shorter than those of the patients in the control group (t=9.511, 8.740; P<0.05). Totally 96% of the patients felt comfortable with the new arm support, and the operation experience satisfaction in 80% of the doctors was excellent, both higher than those of the patients in the control group. Conclusions The performance of this new arm support for bilateral radial artery puncture is stable and reliable. Compared with conventional methods, the time used for preparation before radial artery puncture is shortened for nurses, and the time needed for puncturing and placing sheathing canal in the radial artery is shortened for doctors. The patients feel more comfortable when using this new arm support, and the doctors have a higher experience satisfaction. The new arm support is convenient and flexible for use, and may be used and promoted in cardiac catheterization rooms.

Objective To explore the effects of dietary intervention before selective coronary intervention on patients with type 2 diabetes mellitus and to provide reference and basis for building a feasible and practical preoperative dietary management system. Methods Totally 300 patients with type 2 diabetes mellitus who received coronary intervention in the Cardiac Catheterization Room of Peking Union Medical College Hospital from December 2016 to December 2017 were selected by convenient sampling and divided into the control group (n=150) and the observation group (n=150) according to the random number table. Patients in the control group were fasted for solids and liquids for 4 hours before coronary intervention, while patients in the observation group received foods and drinks for diabetic patients rather than being fasted for solids and liquids as well as individualized dietary guidance from dieticians, specialized diabetes nurses and intervention nurses jointly. The incidence rate of perioperative hypoglycemia. hunger, thirst, anxiety score before and after the intervention, comfort of dietary management were evaluated between the two groups. Results The control group scored higher in hunger, thirst and anxiety than the observation group (P＜0.05);the comfort of dietary management was higher in the observation group than in the control group (P＜ 0.05);the incidence rate of perioperative asymptomatic hypoglycemia in the observation group was 2.0%, while that in the control group was 20.6%;the incidence rate of perioperative symptomatic hypoglycemia in the observation group was 0, while that in the control group was 1.3%. Conclusions Patients with type 2 diabetes mellitus should not be fasted for solids and liquids as conventionally did before selective coronary intervention. Rather, a scientific preoperative dietary management model can prevent the incidence of perioperative hypoglycemia in patients with type 2 diabetes mellitus, enhancing the comfort and safety of operation during the perioperative period.
