Development and Application of a Self-management Program based on Prothrombin INR Monitoring for Patients with Cardiac Valve Replacement

PURPOSE: The purpose of this study was to develop and evaluate a self-management program based on INR monitoring for patients with cardiac valve replacement. METHODS: This program was comprised of five weekly sessions based on Sousa's Enhance-Behavior Performance Model. The first session included individual teaching, and the other four sessions included Prothrombin Time International Normalized Ratios (PT INR) self-monitoring, telephone counseling and self-management checklist recording. Participants were patients who had cardiac valve replacement. They were randomly assigned to the experimental or control group. Sixteen in the experimental group participated in the self-management program and seventeen in the control group participated in general care. Self-management knowledge, self-efficacy, self-management behavior and PT INR were measured as dependent variables. Data were analyzed using Mann Whitney U-test, t-test and ANCOVA. RESULTS: The experimental group showed significantly higher post-test scores in self-management knowledge (t=5.86, p <.001), self-efficacy (F=18.32, p <.001), and self-management behavior (t=3.44, p =.002) compared to the control group. Also, the experimental group showed significantly higher frequency in maintaining the treatment range of PT INR compared to the control group (chi2=4.80, p =.028). CONCLUSION: The results of the research on the self-management program based on PT INR monitoring showed that it is effective in improving self-management knowledge, self-efficacy, and self-management behavior as well as maintaining treatment range of PT INR of patients with cardiac valve replacement.

The Effect of Transcutaneous Electrical Nerve Stimulation on Pain and Pulmonary Function with Post-Lobectomy Patient with Lung Cancer / 성인간호학회지

PURPOSE: This study was designed to evaluate the effect of TENS on pain and pulmonary function of post-lobectomy patients with lung cancer. METHODS: The study data collection was done from February 4, 2008 to February 7, 2009. The subjects were assigned at random to the experimental group and control group with 20 subjects in each group. The experimental group was measured for pain and pulmonary function after surgery and then again after applying TENS 100 Hz frequency and 40 mA output for 20 minutes. The control group was measured the same as the experimental group except applying sham TENS. RESULTS: The pain score of the experimental group which had TENS applied revealed that there were more significant reductions than the control group which had sham TENS applied. There was no significant difference with the number of times of receiving analgesics between the experimental and control group. The effect of TENS on pulmonary function was significantly different between the experimental group and the control group on VC 2 hours after surgery. There was no significant difference between FVC and FEV1. CONCLUSION: The findings of the study indicate that the TENS is effective in easing the pain of patients after a lobectomy.
