Objective:To explore the effect of case teaching in clinical nursing teaching and medical ethics ed-ucation in the department of cardiology. Methods: A sample of 75 nurse interns came to practice in November 2014 to April 2015 were allocated to the control group, while 96 nurse interns came in July 2015 to December 2015 were allocated to the experimental group. The interns in control group were taught according to the traditional teach-ing method, and the case teaching method was used in the experimental group. The scores of critical thinking abili-ty and the times of praise were compared between the two groups. Results:Both critical thinking ability and praise of the interns in the experimental group were better than those in the control group ( P<0 . 01 ) . Conclusion:In-troducing the case teaching method to clinical nursing teaching and moral education can improve nurse interns′clin-ical critical thinking ability and stimulate the enthusiasm for learning. Meanwhile, it is beneficial to cultivate nurse interns′medical humanistic spirit and improve the medical humanistic quality.

Objective To evaluate effects of design of compression and fixation device for wound after permanent pacemaker implantation on compression hemostasis, working intensity of nursing staff and patients′ comfort. Methods Cotton cloth, Velcro tape and snap-fastener were used to design a compression and fixation device for wound after permanent pacemaker implantation. Sixty patients after permanent pacemaker implantation were randomly divided into compression and fixation device group (observation group), and traditional compression group (control group). In addition, the effects of postoperative complications, allergy to medical tape and working intensity of nursing staff for caring wound were evaluated. Results Comparing to the control group, there were significantly lower incidence rate of skin allergy (P<0.05) and shorter working hours needed for nursing staff to care wound (P<0.05).The complications of two groups have no significant differences (P>0.05). Conclusions This design of compression for wound after permanent pacemaker implantation is able to decrease working intensity of nursing staff, improve patients′comfort and show no effects on increasing postoperative complications.

Objective To investigate the effect of radial artery hemostat (TR Band) continuous compression time on bleeding of puncture point, thumb perception, palm swelling and subjective comfort in patients undergoing transradial percutaneous coronary intervention. Methods One hundred and fifty-five patients who underwent transradial percutaneous coronary intervention were randomly divided into two observation groups and a control group. All patients in the three groups were treated by TR Band patent hemostasis. All three groups received the consistent deflation schedule, except the TR Band was removed at the 12th hour post operation in the control group, and at the 6th hour in the 1st observation group and at the 4th hour in the 2nd observation group. Postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort were observed in the three groups. Results The differences of postoperative bleeding of puncture point, thumb perception, palm swelling and subjective comfort among the three groups were statistically significant (χ2=6.31, P<0.05; F=5.26, 4.00, 14.69, P<0.01). In the 2nd observation group, palm swelling was the lowest, but perception, and comfort and bleeding rate is the highest among the three groups. In the 1st observation group, the overall indexes were medium among the three groups. Conclusions The optimal compression duration of TR Band post transradial percutaneous coronary intervention is 6 h, which does not increase the risk of bleeding, but also significantly improve local swelling and perceptual experience, and increase patient comfort.
