目的探讨护理干预在预防肺癌患者心血管系统并发症中的应用效果。方法选取2013年8月至2014年8月间南京市第一医院收治的160例肺癌手术患者,按照床位单双号分为观察组和对照组,每组80例。观察组患者采用循证护理,对照组患者采用常规护理,比较两组患者术后肺功能、疼痛情况及心血管并发症发生率。结果观察组患者术后第5d的氧气分压(PO2)高于对照组,二氧化碳分压(PCO2)低于对照组,第1s用力呼气容积(FCV1)大于对照组,术后第3d的疼痛情况轻于对照组,两组比较,差异均有统计学意义(均P<0.05)。观察组患者左心衰、窦性心动过速及心房纤颤等心血管并发症少于对照组,两组比较,差异有统计学意义(P<0.05)。结论循证护理能够减少肺癌患者术后心血管并发症。 Objective To explore the effect of nursing intervention on the prevention of cardiovascular complications in patients with lung cancer. Methods Totally 160 patients with lung cancer who underwent operation from August 2013 to August 2014 in Nanjing No.1 Hospital were divided into observation group and control group according to single and double bed number. Evidence-based nursing was used in the observation group and routine nursing in the control group. The postoperative pulmonary function, pain and cardiovascular complications were compared between the two groups. Results The oxygen partial pressure (PO2) of the observation group was higher than that of the control group on day 5 postoperatively. The partial pressure of carbon dioxide (PCO2) was lower than that of the control group. The forced expiratory volume (FCV1) at 1s was greater than that of the control group. The situation was lighter than the control group, the difference between the two groups was statistically significant (P <0.05). The cardiovascular complications such as left heart failure, sinus tachycardia and atrial fibrillation in the observation group were less than those in the control group. There was significant difference between the two groups (P <0.05). Conclusion Evidence-based nursing can reduce postoperative cardiovascular complications in patients with lung cancer.
