Patients' inability to perform a preoperative cardiopulmonary exercise test or demonstrate an anaerobic threshold is associated with inferior outcomes after major colorectal surgery

摘要: Abstract Background Surgical patients with poor functional capacity, determined by oxygen consumption at anaerobic threshold (AT) during cardiopulmonary exercise testing (CPET), experience longer hospital stays and worse short- medium-term survival. However, previous studies excluded who were unable to perform a CPET or failed demonstrate an AT. We hypothesized that such are risk of inferior outcomes after elective surgery. Methods All undergoing major colorectal surgery attempted assist in the planning care. Patients stratified their test results into Fit (AT ≥ 11.0 ml O2 kg−1 min−1), Unfit Results Between March 2009 April 2010, 269 consecutive screened, proceeded bowel resection. Median stay was 8 days (IQR 5.1–13.4) there 44 deaths (16%) 2 yr; 26 (9.7%) categorized as Unable CPET, 69 (25.7%) 174 (64.7%) Fit. There statistically significant differences between three groups [median (IQR) 14.0 (10.5–23.8) vs 9.9 (5.5–15) 7.1 (4.9–10.8) days, P Conclusions Patients’ inability is associated Future evaluating assessment for should report this subgroup.
