Objective To observe the effect of precision nursing based on visualization technolo-gy in treating patients with pulmonary nodule surgery.Methods A total of 186 patients with surgery for pulmonary nodules were randomly divided into control group and observation group,with 93 cases in each group.The control group was given routine nursing,while the observation group was given vi-sualization technology assisted precision nursing on the basis of the control group.The psychological status[the Self-rating Anxiety Scale(SAS)score and the Self-rating Depression Scale(SDS)score]and postoperative recovery[score of the Quality of Recovery Scale with 15 items(QoR-15)]were compared between two groups,and the nursing satisfaction degree was compared between the two groups as well.Results After the intervention,the scores of SAS and SDS in both groups de-creased,and the score of each item in the observation group was significantly lower than that in the control group(P＜0.05);after intervention,the each item of the QoR-15 and the total score in the observation group were significantly higher than those in the control group(P＜0.05);the nursing satisfaction degree of the observation group was 97.8％,which was significantly higher than 89.2％in the control group(P＜0.05).Conclusion Precision nursing based on visualization technology can improve the adverse psychological state of patients with pulmonary nodule surgery,enhance the quality of postoperative recovery,and increase nursing satisfaction degree.
