Objective To analyze the nursing cost effectiveness of non-indwelling bladder catheter in thora-coscopic sublobectomy,and in order to further determine the feasibility of patients undergoing sublobectomy without indwelling catheter.Methods We prospectively collected the clinical data on a total of 254 patients undergoing thoracoscopic sublobectomy in the department of pulmonary surgery of Guangdong Provincial People's Hospital from May 2021 to January 2023.The patients were randomly divided into a study group(128 patients without catheter)and a control group(126 patients with catheter).The nursing cost-effectiveness indexes and postoperative comfort scores were compared between the two groups.Results Seven patients in the experimental group and sixteen patients in the control group needed repeated placement of urinary catheter There were no significant differences in the general demographic and clinical data between the two groups(P>0.05).The cost of materials related to urinary catheter,nursing cost,and total cost in the control group were higher than those in the study group.The total nursing time in the control group was longer than that in the study group.The per capita material cost,nursing cost and total cost in the control group were higher than those in the study group,and the differences were statistically significant(P<0.01).The total score of the comfort scale and the physiological and environmental dimension of postoperative comfort were significantly higher in the study group than in the control group,with statistical significances(P<0.05).Conclusions Thoracoscopic sublobectomy without indwelling bladder catheter can lower medical expense,reduce nursing workload,and improve postoperative comfort.
