Objective To investigate the influence of mental nursing on mental status and nursing quality in patients with thoracic surgery.Methods A total of 60 patients underwent thoracic surgery in a hospital in Zhengzhou from June 2016 to June 2018 were selected and divided into the mental nursing group（n=30）and the routine nursing group（n=30）according to random digits table.Patients in the routine group received routine nursing

while in the mental nursing group received routine nursing and mental nursing.Scores of symptom check list（SCL-90）and Pittsburgh sleep quality index（PSQI）of patients in two groups before admission and after discharge were compared;operating time

hospitalization time and nursing satisfaction of patients in two groups were compared.Results SCL-90 scores of anxiety

depression

fear

coercion

paranoia

hostility

psychosis and interpersonal relations in the mental nursing group when discharging were（1.40±0.11）

（1.17±0.05）

（1.01±0.10）

（1.21±0.12）

（0.71±0.04）

（1.14±0.13）

（0.81±0.04）and（1.04±0.08）

respectively.All were lower than those in the routine care group

which were（1.50±0.21）

（1.40±0.11）

（1.21±0.08）

（1.41±0.13）

（1.10±0.20）

（1.31±0.17）

（1.15±0.03）and（1.14±0.05）

respectively;all differences were statistically significant（P<0.05）.When discharging

PSQI score in the mental nursing group was（7.6±1.1）

which was lower than that of（9.6±1.2）in the routine nursing group

with statistically significant differences（P<0.05）.Operating time and hospitalization time in the mental nursing group were（225.1±38.8）min and（7.7±2.2）d

both of which were shorter than those of（229.7±40.1）min and（10.0±2.3）d in the routine nursing group

with statistically significant differences（P<0.05）.Total satisfaction degree in the mental nursing group was 83.3%

which was higher than that of 56.7%in the routine group

with statistically significant differences（P<0.05）.Conclusion Mental nursing can effectively improve mental status and nursing quality in patients with thoracic surgery

which is worthy of clinical promotion.
