205 patients were enrolled: 60 (29.3%) showed RRI > 0.70. The total rate of adverse event was 27 (18.6%) in RRI ≤ 0.7 group and 19 (31.7%) in RRI > 0.7 group (P = 0.042). Significant correlation between RRI > 0.70 and complications resulted in pneumonia (P = 0.016), septic shock (P = 0.003), and acute renal failure (P = 0.001) subgroups. Patients with RRI > 0.7 showed longer ICU stay (P = 0.001) and lasting of mechanical ventilation (P = 0.004). These results were confirmed in cardiothoracic surgery subgroup. RRI > 0.7 duplicates triplicates the risk of complications, both in general (OR 2.03 93 95% CI 1.02-4.02, P = 0.044) and in cardiothoracic (OR 2.62 95% CI 1.11-6.16, P = 0.027) population. Furthermore, we found RRI > 0.70 was associated with a triplicate risk of postoperative septic shock (OR 3.04, CI 95% 1.5-7.01; P = 0.002).
