INTRODUCTION: One hundred adult patients hospitalized in the surgical wards of two hospitals of Belo Horizonte city, Brazil, were separated into two groups: group 1, 22 patients who had no previous experience with surgeries; and group 2, 78 patients who had been previously submitted to major surgical procedures. OBJECTIVE: To evaluate the impact of psychical stress on patients submitted to major operations under general anesthesia and to correlate physical and psychological reactions to different stages of stress. METHOD: The Stress Symptoms Inventory for Adults was used one day before and two and seven days after the operation. The groups were compared with regard to sex, level of pain and stress percentage with the chi-square test and for age with the Student t test. The level of significance was set at p < 0.05. RESULTS: The groups were not homogeneous regarding the general percentage of stress on the occasion of the three measurements. The level of stress was decreased in Group 1 and increased in Group 2. Psychic stress symptoms prevailed in both groups. CONCLUSION: Previous experience with surgery under general anesthesia reduces preoperative stress, but does not affect postoperative stress.
