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.

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 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 .

临床工作中经常遇到为患者滴眼药的工作。以往方法为护士按照六步洗手法洗净双手，左手拇指和食指分开患者上下眼睑，右手将眼药滴入；或要求患者自己分开上下眼睑，护士将眼药滴入。这2种方法分别存在不足：护士洗净双手后接触患者的眼药瓶及瓶盖，手部已不再清洁，然后左手接触患者眼睑，因此易造成感染；患者自己分开上下眼睑，与护士滴入眼药操作不能很好配合，易造成患者疲劳或眼药滴在眼外，造成剂量不准、药液浪费甚至达不到治疗目的。
