Sex Differences in Chronic Postsurgical Pain after Open Thoracotomy.
Journal of Cardiothoracic and Vascular Anesthesia 2024 September 4
STUDY OBJECTIVE: To determine the incidence of chronic postsurgical pain (CPSP) in women after open thoracotomy. Secondary objectives were to compare relevant patient and procedural variables between women and men.
DESIGN: Observational cohort study.
SETTING: Ten university-affiliated hospitals.
SUBJECTS: Ninety-six women and 137 men.
INTERVENTIONS: Scheduled open thoracotomy.
MEASUREMENTS: Pain histories, psychological measures, and perceived health status and catastrophizing scores were obtained. The diagnosis of chronic postsurgical pain was by physical examination at 4 months. Standard preoperative, intraoperative, and postoperative data were also recorded.
MAIN RESULTS: The chronic postsurgical pain incidence was significantly higher in women (53.1%) than in men (38.0%) (p = 0.023). At baseline, women had significantly worse scores on psychological measures (perception of mental state [p = 0.01], depression [p = 0.006], and catastrophizing [p < 0.001]). Women also reported more preoperative pain in the operative area (p = 0.011) and other areas (p = 0.030).
CONCLUSION: These findings show that the incidence of physician-diagnosed chronic postsurgical pain is higher in women than in men after surgeries involving thoracotomy. Sex and gender should be included in future clinical research on pain in surgical settings.
