| Summary: | 碩士 === 國立臺北護理健康大學 === 護理研究所 === 101 === Wound infection may lead to the complication of postoperative wound, so the prevention of postoperative wound infection not only reduces the psychological and physiological stress of patients, but also decreases the length of states in hospital and medical costs. Different dressing solutions used do not have the same effect of preventing wound infection. So far no recommendation is clearly made for selecting dressing solution for wound care after surgery. The purpose of this study was to compare the two kinds of dressing for wound care in infection rate after cardiac surgery, wound pain, and material costs. A repeated measures experimental research study was conduct with two groups. The experimental group provided normal saline solution alone for wound care; whereas the control group provided normal saline with povidone-iodine solution. Finally, 154 participants who underwent coronary bypass surgery or valve-related surgery at a medical center. The average age was 61.88 years. Data was analyzed by IBM SPSS 20.0. Descriptive statistics included frequency, percentage, mean, and standard deviation; and inferential statistics involved chi-square test, two-samples of independent t-test and linear mixed effect models. The results showed no statistically significant difference between two groups in wound infection rate , ASEPSIS score (F=.04, p =.84), wound pain scores (F=.92, p=.34), but dressing material costs (t=9.017, p<0.001). Using normal saline alone did not increase postoperative wound infection, and wound pain. This intervention could reduce the cost of dressing. Normal saline may be used as wound dressing after cardiac surgery. Further study suggests to observe more understanding about normal saline using wound care after surgery for other surgical wounds.
