RESUMO
Objective:To construct a bowel preparation nursing guidance based on key point control theory and mind mapping in full abdominal enhanced CT examination to provide a basis for improving the intestinal preparation and image quality of intestinal patients.Methods:This was a randomized controlled trial, 104 patients were selected as the research subjects who underwent full abdominal enhanced CT examination in the Second Hospital of Shanxi Medical University from January to August 2022, and randomly divided into the control group and the intervention group by table of random numbers, 52 cases in each group. The control group was given routine nursing guidance, while the intervention group was given nursing guidance based on key-point control theory and mind mapping. Compare the differences in intestinal cleanliness, intestinal fullness and CT image quality between the two groups.Results:The proportion of patients with good intestinal cleanliness was 65.4% (34/52) in the intervention group, which was higher than 25.0% (13/52) in the control group ( χ2 = 22.32, P<0.01). The proportion of patients in the intervention group with grade I intestinal filling was 71.2% (37/52), which was higher than the 23.1% (12/52) in the control group ( χ2 = 27.76, P<0.01). The proportion of patients in the intervention group with excellent image quality was 80.8% (42/52), higher than 30.8% (16/52) in the control group ( χ2 = 28.56, P<0.01). The score of State Anxiety Inventory score of patients in the intervention group was (41.21 ± 5.08), lower than that of the control group (48.69 ± 6.40) ( t = 6.60, P<0.01). The satisfaction score of patients in the intervention group was 43.50(39.00, 46.00), which was higher than that of the control group 39.00(36.25, 43.00) ( Z = - 3.45, P<0.01). Conclusions:The bowel preparation nursing guidance based on key-point control theory and mind mapping can effectively improve bowel preparation of patients and the image quality of full abdominal enhanced CT examination.
