Does a previous surgical experience interfere on psychic stress in patients submitted to major surgery?

to evaluate the impact of stress in patients undergoing major surgeries under general anesthesia, relating their physical and psychic reactions to the different stages of stress.

we studied 100 adult patients of both genders, who were divided into two groups: Group 1 - 22 patients without experience with surgery; Group 2 - 78 patients previously submitted to medium and major surgery. To investigate the stress, we used the Inventory of Stress Symptoms for Adults, developed by Lipp, the day before the procedure and two days and seven days after the operation. The comparison of groups with respect to gender, pain, and percentage of stress were performed using the Chi-square test, and for the age variable the Student's t test was used. Differences were considered significant at p<0.05.

the groups were not homogeneous as for the overall percentage of stress on the three measurements. G1 had decreased postoperative stress, whilst in G2 it increased. Psychological symptoms of stress prevailed in both groups.

previous surgery reduced preoperative stress but did not affect postoperative emotional disorders.
