目的：探讨对心脏外科术后患者应用循证护理对预防切口感染的效果，以期为临

目的：探讨对心脏外科术后患者应用循证护理对预防切口感染的效果，以期为临床心脏外科术后患者提供针对性护理干预方案提供有力的客观依据。方法：纳入我院心脏外科2023年2月~2023年8月收治的100例患者，采用随机数字表法分组，对照组与观察组，各50例，所有患者均择期手术治疗，根据分组采取不同护理干预，对照组行常规护理，观察组行循证护理，观察并评估两组术后切口愈合情况，统计两组临床指标，检测两组护理干预前后血红蛋白（Hemoglobin，Hb）、白细胞计数（white blood cell，WBC）、中性粒细胞（Neutrophil，N%）等血细胞指标水平变化，应用Kolcaba的舒适状况量表（general comfort questionnaire，GCQ）评估两组护理干预前、护理干预后3d、护理干预后7d身心舒适状况。结果：观察组切口愈合率较对照组高（P＜0.05）；观察组手术时间、切口恢复时间、抗生素应用时间、住院时间较对照组短（P＜0.05）；护理干预前，两组Hb、WBC、N%水平无明显差异（P＞0.05），护理干预后，观察组WBC、N%水平较对照组高，Hb水平较对照组低（P＜0.05）；护理干预前，两组GCQ评分无明显差异（P＞0.05），护理干预后3d、7d，观察组GCQ评分较对照组高（P＜0.05）。结论：对心脏外科术后患者应用循证护理对预防切口感染的效果显著，通过护理干预不仅可避免术后切口感染发生，同时还可促进切口愈合，对巩固手术治疗成效、预防术后炎症反应、提高身心舒适度具有重要意义，值得大力推广

Objective: To explore the effectiveness of evidence-based nursing in preventing incision infection in patients after cardiac surgery, in order to provide a strong objective basis for targeted nursing intervention plans for clinical cardiac surgery patients. Method: A total of 100 patients admitted to the cardiology department of our hospital from February 2023 to August 2023 were randomly divided into a control group and an observation group, with 50 patients in each group. All patients were scheduled for surgical treatment, and different nursing interventions were taken according to their grouping. The control group received routine care, while the observation group received evidence-based care. The postoperative wound healing of the two groups was observed and evaluated, and clinical indicators of the two groups were statistically analyzed, Detect changes in blood cell indicators such as hemoglobin (Hb), white blood cell (WBC), and neutrophil (N%) levels before and after nursing intervention in two groups. Use Kolcaba's General Comfort Questionnaire (GCQ) to evaluate the physical and mental well-being of both groups before, 3 days after, and 7 days after nursing intervention. Result: The incision healing rate in the observation group was higher than that in the control group (P<0.05); The observation group had shorter surgical time, incision recovery time, antibiotic application time, and hospital stay compared to the control group (P<0.05); Before nursing intervention, there was no significant difference in Hb, WBC, and N% levels between the two groups (P>0.05). After nursing intervention, the WBC and N% levels in the observation group were higher than those in the control group, while Hb levels were lower than those in the control group (P<0.05); Before nursing intervention, there was no significant difference in GCQ scores between the two groups (P>0.05). On the 3rd and 7th days after nursing intervention, the GCQ scores of the observation group were higher than those of the control group (P<0.05). Conclusion: The application of evidence-based nursing to patients after cardiac surgery has a significant effect on preventing incision infection. Nursing intervention can not only avoid postoperative incision infection, but also promote incision healing, which is of great significance for consolidating surgical treatment effectiveness, preventing postoperative inflammatory reactions, and improving physical and mental comfort. It is worth vigorously promoting

Objective: To explore the effect of evidence-based nursing on preventing incision infection in patients after cardiac surgery, so as to provide a strong objective basis for providing targeted nursing intervention programs for patients after clinical cardiac surgery. Methods: 100 patients admitted to cardiac surgery in our hospital from February 2023 to August 2023 were randomly divided into control group and observation group, with 50 patients in each group. All patients were treated by elective surgery, and different nursing interventions were taken according to the grouping. The control group was given routine care, while the observation group was given evidence-based care. The postoperative wound healing of the two groups was observed and evaluated, and the clinical indexes of the two groups were counted. The changes of Hemoglobin (Hb), white blood cell count (WBC) and Neutrophil (N%) before and after nursing intervention were detected, and the physical and mental comfort of the two groups was evaluated by Kolcaba's general comfort questionnaire (GCQ) before nursing intervention, 3 days after nursing intervention and 7 days after nursing intervention. Results: The wound healing rate in the observation group was higher than that in the control group (P < 0.05). The operation time, incision recovery time, antibiotic application time and hospitalization time in the observation group were shorter than those in the control group (P < 0.05). Before the nursing intervention, the levels of Hb, WBC and N% in the two groups had no significant difference (P > 0.05). After the nursing intervention, the levels of WBC and N% in the observation group were higher than those in the control group, while the level of Hb was lower than that in the control group (P < 0.05). Before the nursing intervention, there was no significant difference in GCQ scores between the two groups (P > 0.05). On the 3rd and 7th day after the nursing intervention, the GCQ scores in the observation group were higher than those in the control group (P < 0.05). Conclusion: Evidence-based nursing has a significant effect on preventing incision infection after cardiac surgery. Nursing intervention can not only avoid postoperative incision infection, but also promote incision healing, which is of great significance for consolidating the effect of surgical treatment, preventing postoperative inflammatory reaction and improving physical and mental comfort, and is worth popularizing.
