Association Between Sternotomy Versus Thoracotomy and the Prevalence and Severity of Chronic Postsurgical Pain After Mitral Valve Repair: An Observational Cohort Study.

摘要: Objective Investigate differences in the prevalence and severity of chronic postsurgical pain (CPSP) after cardiac surgery via thoracotomy versus sternotomy are not well-understood. Design An observational cohort study. Setting A tertiary care hospital. Participants Four hundred twenty-eight patients (sternotomy: 192 patients, thoracotomy: 236 patients) who underwent mitral valve repair. Interventions questionnaire about surgical wound evaluated with a numerical rating scale (NRS) was sent. NRS responses for current pain, peak last four weeks, average weeks were evaluated. Measurements Main Results The main outcomes CPSP using CPSP. defined as >0 that developed procedure. During median follow-up 29 months, 79 complained 15 64 patients). Multivariate ordinal logistic regression showed (adjusted odds ratio [aOR], 3.17; 95% confidence interval [CI] 1.64-6.12; p = 0.001), (aOR, 2.00; CI 1.11-3.61; p = 0.021), 2.21; 1.31-3.72; p = 0.003) significantly higher thoracotomy. an independent predictor 3.63; 1.67-7.88; p = 0.001). Conclusions among repair than sternotomy.
