To explore the influence of before operation intervention on the patients undergoing parastomal hernia repair.

From June 2018 to April 2019, 42 patients who underwent parastomal hernia surgery in Guang'an people's Hospital were selected as the objects of observation, including 23 males and 19 females. The average age of the patients was 38.5 years old. According to the random number table, 21 cases in each group were randomly divided into intervention group and control group. Patients in the control group received routine preoperative examination, intraoperative and postoperative care. The patients in the intervention group were given positive psychological guidance before, during and after operation on the basis of routine nursing. The heart rate, blood pressure and other vital signs of the two groups were recorded, and the anxiety index of the patients was measured by Zung self-rating anxiety scale (SAS).

The blood pressure of the intervention group before anesthesia and when the tracheal tube was pulled out was more stable than that of the control group [(116.25±8.79) mmHg vs (129.17±7.65) mmHg, (121.35±15.30) mmHg vs (126.17± 10.85) mmHg], the difference was statistically significant (t=5.24, 8.173, P<0.05). The heart rate of the intervention group before anesthesia and when the catheter was pulled out was stable compared with that of the control group [(71.23±7.26) bpm vs (80.26±7.63) bpm, (77.39±5.63) bpm vs (85.26±11.69) bpm], the difference was statistically significant (t=6.358, 8.241, P<0.05). Before anesthesia and 3 days after operation, the SAS score of the intervention group was lower than that of the control group [(42.63±76.69) scores vs (48.26±6.62) scores, (43.16±6.32) scores vs (46.28±5.32) scores], the difference was statistically significant (t=2.356, 2.145, P<0.05).

The psychological intervention in operating room has a significant stabilizing effect on the emotional and physiological characteristics of the patients.
