Gynaecological operation as an objective stressor in women.
OBJECTIVE
The purpose of the study was to verify the usefulness of Number Scale of 0-10 points (used to assess pain) and the concentration of prolactin (PRL) in the blood serum for the evaluation of stress in patients undergoing surgical intervention on gynaecological wards.


METHODS
The study was carried out among 200 patients with different gynaecological illnesses operated in The Department of Reproduction and Andrology Skubiszewski Medical University of Lublin. The study used a questionnaire and Medical Documentation Analysis Sheet, especially constructed for the purpose of study, and Numerical Scale 0-10 to self-evaluate the stress level. Moreover, prolactin (PRL) concentration as a marker of stress reaction in the blood serum has been evaluated as well. The differences were determined by U Mann-Whitney and Kruskal-Wallis tests. Wilcoxon's test was used to compare the parameters examined on two levels in dependent groups. The calculations assumed 5% conclusion error and p<0.05 as statistically significant different.


RESULTS
The patients reported higher stress prior to the operation than after it (p<0.001). PRL concentrations were significantly higher in the patients after the operation (p<0.001). No correlation between subjective level of stress and PRL concentrations before operation (p=0.254) have been found. The patients who reported higher stress had higher PRL concentrations in the postoperative period. The highest PRL concentrations were observed in the patients who underwent laparoscopy and laparoscopy with hysteroscopy and the lowest values were noted among the patients after hysteroscopy.


CONCLUSIONS
Surgical intervention was perceived by women as stressful, disregarding the type and extent of an operation. Patients' subjective evaluation revealed higher stress level before the operation while they were waiting for the surgery. Contrary to that, prolactin concentration was higher in the first day after the surgery. Therefore, prolactin was not an objective marker of psychological stress in the examined group. Trauma caused by surgical intervention as a biological stressor induced an increased prolactin concentration in blood serum during the postoperative period.
