Objective To explore the application value of nursing model based on Snyder's hope theory in patients with permanent enterostomy after radical rectal cancer surgery.

Methods A total of 100 patients with permanent enterostomy after radical resection of rectal cancer were randomly divided into control group and study group, with 50 patients in each group. Control group received routine nursing mode, and the study group received nursing mode based on Snyder's hope theory, and the perioperative nursing content was set and implemented according to the theoretical framework of goal, path thinking and dynamic thinking. The anxiety state, hope level, self-care ability and medical coping style were evaluated by self-rating Anxiety Scale (SAS), Herth Hope Scale (HHI), self-care ability Scale (ESCA) and Medical Coping Style Questionnaire (MCMQ) before nursing intervention (admission day) and after nursing intervention (discharge day). The quality of life scale (QLQ-C30) was used to evaluate the quality of life (functional domain, symptom domain and general health status domain) of patients in the two groups before nursing intervention (the day of admission) and after nursing intervention (at 1 month of follow-up after discharge).

Results After nursing intervention, SAS, avoidance and yield scores and symptom domain score were significantly lower than those before nursing intervention, HHI, ESCA, face score and functional domain score and general health domain score were significantly higher than those before nursing intervention (P < 0.05). After nursing intervention, the scores of SAS, avoidance, yield score and symptom domain score in the study group were (53.36±5.22), (13.51±1.22), (11.05±1.01) and (490.55±37.33), which were significantly lower than (57.82±3.42), (18.85±1.65), (15.74±1.40) and (543.33±32.33) in the control group (P < 0.05). The scores of HHI, ESCA, face and functional domain and general health status domain were (42.26±2.28), (123.00±8.10), (23.22±2.01), (336.67±41.33) and (92.33±9.55), which were significantly higher than (36.78±2.74), (105.00±7.18), (16.58±1.46), (300.11±37.66) and (80.33±5.83)in the control group (P < 0.05).

Conclusion Nursing mode based on Snyder's hope theory can effectively relieve patients'anxiety, improve their hope level and self-care ability in patients with permanent enterostomy after radical rectal cancer surgery, which is of significance to the improvement of patients' quality of life and the establishment of positive medical coping styles.
