Abstract Objective This study aimed to evaluate the nociceptive profile and the intake of analgesic drugs of patients submitted to rotator cuff repair surgery. Also, to evaluate the nociceptive thresholds and the integrity of the descending inhibitory system, pain catastrophism and prevalence of nociceptive or neuropathic pain. Methods Approved by the Ethics Committee of La Salle University (1.325.433/2015). 40 patients (>18 years old) who underwent rotator cuff repair surgery (divided in small and large injuries) were recruited. The used instruments were: Sociodemographic Questionnaire, Functional Pain Scale, Visual Analogue Scale (VAS), Quantitative Sensory Test (QST) and Conditioned Pain Modulation Task (CPM). Results Patients had a significant difference in pain thresholds QST heat (independent samples t test) and quality of sleep, mood and anxiety (paired t test) in groups preoperative. There was a significant correlation between preoperative CPM and postoperative VAS (Pearson Correlation). It was observed that, in preoperative, 38 patients used analgesics continuously. Besides that, in postoperative, use of opioid drugs was higher in patients with small injury (13 patients) than in those with large injury (9 patients). Conclusion Therefore, patients with rotator cuff injuries did not present alterations in the descending inhibitory system, but showed alterations in pain thresholds, which may interfere in the postoperative period and still be related to the consumption of analgesics. |
